Right, so I decided to go the BIOS tweaks only way and I’m glad I did. I applied the following settings in PBE:
I went for an overclock to 1350mhz for a start, since I know the GPU is stable at 1400@1125mv. Also, since I can’t use MSI to set a +50 power limit, I upped the Max Power Limit to 187W and decreased the Power Control Limit to 2%. I chose 187 because when stock, the card is set at 125W and 50% Power Control Limit. 125*0.5=62.5. 125+62.5=187.5. So now the card defaults to what’s basically stock and +50 power limit without me having to apply settings in MSI/Wattman, which always screws up the memory timings.

Now it still spikes up to 1158mv, but during gaming I’m seeing mostly 1100 and 1125mv. Will now try to tweak the timings even tho I’m getting 220GB/s at 2050mhz. Might also try further undervolting to 1100 as everything seems stable at 1125. It seems that going for BIOS tweaks only without using OC software is entirely possible and not annoying as I previously thought. A bit like it is with CPU overclocking which I’ve always done in the BIOS.
Oh, and the card is now scoring between 220 and 225 in oclmembench(up from the 210 it used to score with the broken ARB_DRAM_TIMING and ARB_DRAM_TIMING2 values) [[File:Screenshot_23 (2).png|none|auto]] This is with the standard memory strap in the “silent” BIOS I’m experimenting with, so I’m very happy. HWiNFO is showing no errors as well.
For anyone who wants the stock timing for the 2050mhz strap, it is this: 777000000000000022CC1C00CE695D4CF0571218B90DE60B00400700240614207A8900A00300000013123740BE323E18
Thats not bad @TheVic1600 , I don’t have the timings to hand right now but I have an optimised set of Samsung timings that can probably get another 7-10GB/s out of the memory at the same frequency. Let me know if you want to try them and I’ll dig them out.
@ket Yup, It’d be great to try those. I have been trying timings almost every day for a few weeks now and I’ve learned some things about what works for my card and what doesn’t:
-I seem to be hitting a wall at 221GB/s at 2050mhz. I can get 225 and 227GB/s sometimes right after booting into Windows but subsequent tests always result in 221. -2100mhz always results in artefacts unless I loosen the timings so much I end up scoring about 218GB/s. 2075mhz gave me just 1GB/s more but ended up crashing during gaming, so 2050mhz is max my memory can go. -Sensibility to TW2R is huge. I can only lower TW2R from 31 to 29 if I loosen almost everything else and with that I only get 219GB/s, so I’ve given up on that. -ACTRD and ACTWR seem to work at 19 and 18. Loosening those to 22 and 21 lets me go 4 on TRRD with 26 and 55 on TRP_RDA and TRP_WRA(tho I didn’t test more than 1 game with that config, so I’m not completely sure that works) -Memory errors only show up if I lower TW2R and they show up in the millions. Otherwise, instability manifests in the card either showing artefacts(Dirt 3’s Benchmark seems t be great at bringing them when other games don’t) or having a driver/system crash.
Overall, XFX’s silent BIOS default memory timings are surprisingly good. I get the best stable performance when I take the default strap and loosen the timings you said don’t affect performance at all or add stability. With that I can go 22 on the TCL(down from 24), but the performance seems to be the same(still hitting the 221GB/s wall). Interestingly, when I tried to overclock the core to 1400mhz(didn’t work because of the undervolt), I managed to score a consistent 224-225GB/s with the same timings. Does the IMC also work better at higher core frequency? Maybe that’s the key to going over the 221GB/s wall? I can go 1400 on the core, but it requires more voltage and I wouldn’t want the card to become hot and noisy again, so I’d rather stay at 1350 and just accept I can’t go over 221. So yea it would be nice to see what your strap looks like, tho so far this “FC” Samsung VRAM seems to be noticeably worse than the “FB” ones. I’m still happy with the card at 1350mhz equalling a 1380mhz RX580 in 3DMark Fire Strike and Sky Diver. In Dirt 3’s benchmark I’m up 10-11% on the card’s stock result.
@TheVic1600 heres the timing strap if you send me over a copy of your vBIOS I can probably make some tweaks and changes to smooth some things out. Its not an exact science optimising memory on Polaris due to no silicone being created equal but with enough time, testing, and patience you can nail it down to 95% at least some cards might just need a tiny tweak left or right for absolute stability. Samsung memory really doesn’t play nicely on Polaris it doesn’t matter if you have FC or FB Sammy, I had a card with FB Sammy actually and that topped out at 2050MHz no matter what I did or tried, Hynix and Micron memory are very good though last RX590 I played with I got the Micron on that to 2375MHz with optimised timings, or 9500MHz, whatever way you prefer to refer to the memory frequency. I did enough to get like second or third in the Futuremark rankings with systems using a 2700X. I’ll chuck the screens up as a few attachments in case you’re curious as you won’t find the results on Futuremark tables because I’m not the sort to partake in OCing in that way anymore. In case you are wondering the card is seen as an RX580 in the attached images because I modded the vBIOS to get around the driver level check so I didn’t have to keep messing around with a software hack, it was a laziness thing lol.
Anyway, here’s that timing strap for Samsung memory; 777000000000000022CC1C00106A4D4DC0691016378D160B0068C70014051420FA8900A00300000015153F48B1384C1A
There’s a tiny amount of play in the timings but this is for long term stability reasons and because it just doesn’t make any real difference to performance. If these timings aren’t completely stable for you (they likely will be, I made damn sure of that for 95%+ of cases) change these timings: TRRD to 5 (big factor for stability) TCCDS to 5 (should help prop up minimum frames in extreme cases a bit but adversely might lead to a bit of extra microstutter) TRP_RDA to 27 (big factor for stability) TR2W to 29. These changes shouldn’t be necessary but if they are start with just changing TRP_RDA to 27.
@ket Thanks a lot! Will give these a try right away and report later. In my previous post I mixed TW2R and TR2W. I meant to say TR2W. Really curious wether your strap will run as it is with a TR2W that’s tighter than everything i’ve tried so far.
I’ll post my BIOS here if you feel like taking a look over it. I’m pretty ok with it tho what I’d like to fix are the voltage overshoots that still happen. I’ve used HxD to set a VID of 1.075V and while it does stay between 1 and 1.1V most of the times, HWiNFO sometimes still shows spikes of up to 1.181V. The temps and overshoots are clearly lower than at stock tho, so it’s only a minor problem. You mentioned in one post that XFX’s BIOSes are kinda shit and I feel that’s true. I’ve tried adding an offset to the NCP81022 but that section I’m supposed to edit just doesn’t exist in my BIOS. Also one of the 4 parts I’m supposed to edit to change the VDDCI is missing. I’ve also had to fix a broken fan curve which had the card’s minimum fan speed at 75%.
EDIT: Would also be nice if the card got recognized as an RX580 since I have to use that driver patcher to make it work. I have tried using HxD to do the driver bypass tweak in your first post, but it didn’t do anything, the drivers still refused to work without the patch.
EDIT: Well, so far so good. oclmembench is now mostly 222GB/s with some 221 values. FireStrike score is just 1 point(14333) better than what I scored yesterday(14332) but I’m sure you’ve tested your strap for stability way more than I did. Also had no memory errors and no artefacts in 3 Dirt 3 benchmarks in a row so this has passed all my initial stability tests so far. Will later see how it performs in more demanding stuff like Doom 2016 and Wreckfest. The Dirt 3 benchmark scores are about the same as what I got yesterday in terms of avg FPS, but I feel there’s a 1-2FPS improvement on the min FPS values. Great, because I care more about min FPS as my monitor can only display 60FPS so I’m well over that in most of the games I play. Will likely have a go at playing with the values you mentioned as well if something goes wrong.
@ket Oh wow, that’s a lot of changes, thanks a lot. Will try it out in some hours.
And yes, my card has a single 8-pin connector. I just have one question:
Is it safe to increase both TDP and Power Limit as long as TDC stays stock? No worries about the shoddy VRM? I saw some people on another forum calling the VRM as bad as the PowerColor one and that’s the reason I went conservative on setting both. The card wasn’t throttling at 150W power limit so that’s why I left it like that.
Right, I got to test the BIOS and only had one memory error after playing some Dirt 4. The card was a lot more silent than usual, because I didn’t use MSI Afterburner’s custom fan curve but it also got pretty toasty(for my taste at least) at 83C in the most graphically demanding stage I played. The game ran better than usual tho, with fewer and smaller dips under 60fps. Also did a LuxMark test before flashing your BIOS and after and there was a gain of about 90points. I also remembered 1137mv should be enough for 1400mhz core, as I was hitting that with 1125mv previously so I went into PBE to set 1400 and also lowered the High PWM temp down to 75c. Before PBE I used HxD to disable Zero Fan at your suggestion, since I noticed I can’t hear the fan spinning at 20% when the card is idle anyway. Oh and the Max Fan speed setting is broken in XFX’s BIOS as if I set the card at 100% fan speed using Wattman, it reaches 4k RPM despite your 2.2k setting. No problem as I’m pretty sure 2.2k would not be enough to properly cool the card.
Sure enough 1400mhz ended up being stable and I now get 226GB/s in oclmembench. The High PWM adjustment helped too with the max temp now being 78C. At 1400, the LuxMark score jumped another 120points. Dirt 3 Benchmark ended up at 158/134, so my minimum FPS is now just 4FPS under the stock card’s average FPS
I’m reading online that these cards are actually fine at 85-90c for even extended periods of time. Is that true? I was previously desperate to keep the card under 75, despite the jet engine noise necessary for that. If I can actually stretch to 85c, then 1400mhz at 1137mv is actually doable with low-ish noise.
EDIT: The card starts to glitch in Fire Strike as soon as the temperatures get into the upper 70s-lower 80s. Screen starts to randomly cut out(flickers to black) and I also see a few random textures appearing on screen when they shouldn’t. It also begins to throttle at around 75(could have something to do with ‘Target Temp’ being 75 in the BIOS). I thought maybe it’s my 1400mhz overclock but exactly the same thing happened at 1350. It got through the test at 1400mhz, despite the glitches and scored 14495, ~130pts over my previous best. Max temperature was 79C(since I adjusted the ‘Max Temp’ down to 75C from 85C). I cranked up the fan speed to ‘jet engine’ level and attempted another run at 1350 to see if this has to do with high temps. The throttling was reduced, the card only reached 72C and I was thinking this is a thermal issue until a black screen came. Note that this was a black screen in 3DMark. The system or drivers didn’t crash. But yea, I guess it’s time to loosen the timings.
EDIT 2: Managed to achieve stability in 3DMark. Started by changing TRRD(4>5) and TRP_WRA(53>55). At this point the bench still crashed, but at a later stage than before. Setting TRP_RDA(26>27) finally ensured a trouble-free run, despite an 83C temp. This was at 1350 so it remains to be seen what’ll happen at 1400. The throttling is still an issue and I suspect the higher(1.137) auto voltage could be the culprit, as the card was previously holding a solid 1350mhz at 1.075V. Then again 1400mhz with throttling will still end up being faster than 1350 without throttling. Oh and oclmembench scores are exactly the same at these looser timings. Still getting 222-223GB/s at 1350core just as before.
@TheVic1600 see bottom of post for an updated vBIOS that should iron out the kinks, changelog in zip archive. I’d suggest uninstalling the driver with display driver uninstaller from safe mode then reinstalling it to make sure the driver isn’t messing itself up which happens more regular than it should when you are changing memory timings. I’m shooting a bit blind when it come to the fan curve for your card so that might need tweaking still 1137mv I set as I’m unsure what vdroop is like on your card depending on the voltage regulator and if the phases are doubled or not vdroop can be as bad as about 60mv so I assumed worst case scenario here to be safe. The reason you can’t hear the fan at 20% is because if your card is anything like the XFX RX590 I messed around with something is broken in the firmware or the drivers the fans won’t actually spin at all until 35%, and if you set a lower RPM for the idle power limit it just breaks things even more. I’m going to point the finger at XFX for this one. Most GPUs, particularly Polaris, do run toasty but with some really good TIM, proper balancing of fan values and optimising that voltage to GPU frequency curve it is possible to have a fairly cool, power efficient, and quiet running card… even if its an XFX model
If you haven’t already you might want to take a look at how the memory is being cooled on your card XFX cool the memory on the RX590 absolutely terribly (you can check my review of it for details) so its worth looking at your card. If you need to play with timings outside of what I’ve changed things to with this vBIOS the only options you’ll need to try adjusting one at a time in order of what should be the most effective (and reverting the previous change) TRP_RDA 26 > 27, TRRD 4 > 5, TCCDS 5 > 6. Thats it, just those 3 timings, you can try to squeak TRP_WRA down to 53 if you are really looking for every last drop but 55 is the optimal value between stability and performance. In fact those screen blackouts you had by more than any other settings are caused by TRP_WRA being set too tight or TRRD, typically the former not the latter Samsung is REALLY good at holding a stupid tight TRRD. You might also want to try increasing VDDCI to 0.95v if you get memory errors before adjusting timings benefits with a lower or higher VDDCI is completely hit and miss sometimes slightly lower is better, sometimes not. The only constant here is that higher than 0.95v absolutely does not help with memory stability. Also I’m stupid and looked at the memory straps wrong in that other vBIOS, fixed that now.
@ket Thanks! I’ll give it a go later and I’ll also do a reinstall with DDU if I encounter problems again. As for voltages, the card is all over the place when I’m gaming/benchmarking. With your 1137mv setting I’m seeing anything from 1151 to 1056, with peaks close to 1.2V depending on the load put on the GPU. With a 1075mv setting I’m seeing between 1.1V and 1V with peaks up to 1.15. So it seems that for X max auto voltage, I’m getting X+15mv max and X-75mv min with X+70mv peaks. Vdroop is very hard to gauge in these conditions so I’ll probably tweak the voltage myself and see if I can get rid of the throttling. I know the card didn’t throttle at 1350mhz@1075mv, but it couldn’t hold 1400mhz with that voltage, so maybe somewhere between 1137 and 1075 would be the sweet spot for 1400mhz.
As for the fans, I am 100% sure they are spinning@20% as I have checked with the flashlight on my phone and have seen them start to spin as soon as Windows gets to the login screen. HWiNFO also shows the GPU Fan at around 1k RPM when the card is idle and cold.
https://www.overclockersclub.com/reviews…gb_xxx_edition/ This is a review of my card where they take it apart. The memory cooling situation doesn’t seem too bad if you ask me. They seem to be right under the heatsink under the fans. But then again I don’t know much about GPU coolers. I imagine it would be better if they stuck some small heatsinks on the modules. Either way, the fact that the card passed the 3DMark test with looser timings despite being over 80C makes me think thermals aren’t a big problem on this card right now.
As for VDDCI, if you look at the screenshots from my previous post, you can see that it’s always locked at 838mv under load. I don’t know if you adjusted it or not but I remember when I tried to change it, I only found 3 of those 4 B6 03 values I’m supposed to change. Also, while the first 2 were at the same offsets as the ones in your guide, the 3rd one was at a completely different one. Not wanting to risk frying my IMC, I left it as it is. Odd that it stays between 838 and 869mv when it’s actually set at 950mv. Must be another great XFX BIOS “feature”.
@TheVic1600 nope I didn’t change VDDCI at all, different vBIOSes will have some stuff at least at different offsets so that last offset you found B6 03 at should be absolutely fine to change. Memory cooling on your card is actually better than for the 590 but the ICs are probably still getting toasty if you can fit some low profile BGA heatsinks under there I would. Its still better how things are on your card than just letting the modules cook themselves alive like on the XFX 590 though.
not only XFX, but many other vendors "feature" too. you can look back to post #39 i explained how can you change this. doesn’t seem to help a bit, so i’d advise to not even waste time with it
a discussion about max temps could be interesting, 80-90 celsius should definitely be fine, i was running mine in 80c range before decided to change stock thermal paste. rumour has it, starting with polaris, all newer GPUs have dozens of sensors everywhere inside chip and operating temp could reach as high as 110 celsius, part of the chip that is the hottest is the hotspot and this temperature is displayed as a sensor reading
@karmic_koala Thanks. I guess I’ll leave the VDDCI alone as I’m happy with what I’m getting out of the VRAM. I doubt a VDDCI adjustment will let me do 2100mhz judging by what @ket said about Samsung VRAM.
And to think the 590 Fatboy was one of my options last summer when I got the parts in my signature. A big online retailer here had these 3 XFX cards on sale(RS 570, GTS 580 and Fatboy 590) and the 570 looked like the best deal(price/performance), followed by the 590. I seriously considered the Fatboy 590 as it was only slightly more expensive than the GTS 580. But in the end, the 570’s price proved to be too good, so I went with that, knowing I might be able to push it to 580 levels of performance through overclocking. Now I’ve seen RX590s scoring a little under my RX570 in LuxMark, so I’m overall still very happy with the purchase(after modding) despite the card’s flaws. There was no other way I could’ve gotten so much performance for such a small price.
Yup RX570 is underrated hugely the 580 is only like 7% faster at best I really don’t understand why AMD made the 580, without optimising the memory timings on top of that 7% the 580 doesn’t make any sense at all. All that extra core speed on the 590 does practically nothing as well in actual games so if anyone is trying to decide between the 580 and 590, if the 580 is a decent amount cheaper get that or the 570.
@ket Didn’t have much time tonight but gave the new BIOS a try in Fire Strike at 1350mhz core. Throttling was still there, but a lot less and only happened after the card pushed past 75c. At that point it was showing between 1340 and 1349, so no big deal. 1087mv is surely better than 1137 and I expect to be able to hit 1400 at around 1100 or 1087(if I’m really lucky). But before trying that, the memory timings will again need adjustments as the screen flickering to black thing returned. I’ll DDU and reinstall the drivers tomorrow to make sure the problems aren’t driver related and if the problem persists, I’ll adjust the timings as you recommended.
@ket Right, today was very disappointing and I’m beginning to think the card’s actually a turd. Started loosening the timings and ended up at the timings I achieved 2 days ago. Those were no longer stable(flickers/black screens in FireStrike) so I suspected it’s the lower core voltage. Reverted back to 1137mv and the card was still not stable. I had previously got rid of the throttling at 1087mv by raising the TDP to 220. Well, at 1137 the throttling was back, despite the card not pulling more than ~168W. I have nowhere to go. TDP is 220, power limit is 221, 8pin+pcie slot means my maximum is 225. Even worse, going TRP_WRA 57 still meant flickering in 3DMark. Either the test I did 2 days ago was a fluke or I’ve somehow degraded my memory modules from all the benchmarks. Should I just forget about 3DMark and just focus on gaming? Games didn’t crash at all and the flickers in 3DMark occur in the “Demo” bit at the start. The actual benchmarks run without issue. Also did the DDU and driver reinstall, which made no difference.
Update: I flashed the BIOS you originally tweaked and which I then tweaked a little to pass 3DMark Fire Strike 2 days ago. It passed again. No graphical issues whatsoever(but it did behave just like before with throttling). So it wasn’t just a fluke. I might’ve screwed something up today when loosening the timings or your original memory straps screwup actually works for my card, lol. Either way, I’m not so disappointed anymore and the card surely has no damage.
EDIT: Did a Fire Strike test at 1400mhz@1137mv. It was stable for quite a bit of the Demo(still eventually showed artefacts and flickers) and I kept an eye on the voltage in the most stressful bit of the test. It hovered around 1050-1090mv, so quite a bit of vdroop. GPU also throttled down as much as 1335mhz during those low voltages. That’s also the point at which the flickers began, so I’m thinking I’d need more voltage to be stable at 1400. My card’s ASIC quality is 72.3, so I’m thinking of going up to 1150mv(the card’s default voltage) and increasing the med and max PWM since the card is very silent right now.
@TheVic1600 can you get a video of what the card is doing when its artifacting? These timings might need a bit of refining but if it is what I think it is this strap should fix the issue; 777000000000000022CC1C00106A5D4DC0691016BC8D160B0068C70014051420FA8900A00300000015153F48B1384C1A
In short I think you have Samsung 7Gbps memory parts that have just been pre overclocked to 8Gbps from high binned 7Gbps parts by XFX (not the first time I’ve encountered this on a 570, or 470 for that matter) so they aren’t holding up the same as actual 8Gbps parts. If what I think is right its TRRD alone causing the problem but I adjust a couple other timings for the sake of being a little more cautious, if these timings are stable start by pulling TRP_WRA down you’ll get a decent boost.
@ket Will try that strap tonight and also get a video. Is it even possible for XFX to take 7Ghz modules and fake them like this? And could a 7Ghz part do 8.2Ghz at these pretty tight timings(since they are stable at 1350mhz core)? I think the flickering I get at 1400 is core voltage-related. In my old build I had a Radeon HD5750 with Elpida VRAM and I remember those were complete shit at overclocking as they wouldn’t go anywhere higher than stock, which was actually 50mhz under what they were rated for. It was a bottom-end cheapy version of the 5750, so maybe the memory cooling on it was very bad.
Not my video, but this is pretty much what happens to my card. Usually I get the first flicker at this point in the demo, after which the flickers either become more frequent or the screen goes completely black. If the screen goes black, I can see the card’s power consumption in MSI Afterburner’s OSD goes down to 79W and stays constant. If I let the demo run, it actually ‘survives’ the flickers and then the main benchmarks run without any issues, tho they are shorter so the load on the card doesn’t last as long as it does in the demo. The system or drivers don’t crash and pressing Alt+F4 closes the benchmark. The PC behaves normally afterwards.
Haven’t tried the strap yet, just updated the post with that video.
