@wildcard Samsung memory really doesn’t OC well on Polaris, Hynix or Micron is what you want. That 2000MHz strap doesn’t look like a stock strap either looks like some shitty auto optimised PBE timings. I don’t have much time atm with requests spewing out my eyeballs for Polaris and mainboard firmware mods along with writing articles and reviews I think the only way I’m going to fit all this in is to start something donation based for Polaris mods as well otherwise I don’t think I’m even going to have time to sleep 
Hi! I’m working on app for rebuilding modules in vbios. And early method working fine. But I stuck with vbios signature verification. I compare all modules of four vbioses and find out that PowerPlayInfo includes some different two bytes 3125, 3025, 4626, 6326… etc… so possibly they are signatures.

Then i tried to understand Vbios header, and that is what i made:
So vbios has two checksums:
CRC-8 for check spi rom for faulty. If this value is Ok - then Gpu core will load firmware
CRC-32 is based in PCI config, and probably checking data and command tables for checksum ok.
Also i compared this value with 4 gpus
If you know the location of signature in vbios or driver, or how to bypass this on linux-windows, it could be very useful, thanks!
@bigguygeo as far as I am aware Polaris vBIOSes do not have signatures but the driver does do some kind of check for all Polaris cards (except RX580) where if it finds a modified vBIOS the driver will install but not load. Cleanest solution to that problem is to just make the driver think you have an RX580, the other method is to use a software hack that’ll allow the driver to load regardless bypassing the check. I have no idea why AMD put the check into the driver but left out the RX580 in that check, considering Polaris is only any good once you’ve optimised the GPU frequency to voltage curve and fixed the god awful memory timings it was obviously in AMDs best interest to not add a driver level check at all.
I read some forums research, and before pixelclock patch released (possibly Windows registers patch for bios signature verification), users modded driver by reverse engineering to patch return success from verification stack. So I think amd using crc repository for vbios verification. My suggestion is that: scenario is simply compare. Driver read vbios, generating custom checksum to vbios, reading crc repository and then compare generated crc register with checksum repository and return success, jump not equal to other stack.
So if somebody could reverse checksum generation method, than we can fix by patching one reserved for future data or command module and other info type part of vbios, so it will return success to driver and that’s all.
I wouldn’t know on that front @biguygeo you’d need to ask someone who has messed around with the AMD Windows driver but finding someone that has will be difficult nobody wants to touch AMDs Windows driver because from all reports I’ve seen that driver is a total clusterfuck.
I believe you. But I think that somebody will get it useful. Many users have successfully modded 5xx with simple decimal sum fix of unused bytes. Someone even succeeds with 5700 xt modding. This crc checksum verification applies only on file size of vrom (65 kbs) other modules like gop and gop table resource are away from crc check.
I found this:
///////////////////////////////////////////////////////
This FFFFF padding outside of the file is used to fill unexpected end of file and nothing more. Still can’t understand how file size equals hexfile length
Ok, FILE SIZE?
73E9 = E973 = E600
74E9 = E974 = E800
76E9 = E976 = EC00
78E9 = E978 = F000
79E9 = E979 = F200
7FE9 = E97F = FE00
80E9 = E980 = 10000
Still can’t understand how this is working, but maybe its sort of EFI image rules of file size
///////////////////////////////////////////////////////
So checksum check is limited by this value size. This value is simply after 55AA at the beginning of the vrom
I haven’t looked at the state of RDNA modding a whole lot, I know its got some people working on it but anything like vBIOS mod tools are a way off still from what I’ve seen. If you have any useful links for 5700XT modding then I’ll take a look at those to check in again on how its going.
For some reason I can’t post links
So simply add www

Can someone help me remember how to change the VDDC offset in hex? Thanks
I want to set 1.250v from 1.100v
https://www.mediafire.com/file/5j285ph64…-strap.rom/file
Nevermind I got it. If anyone wants a 1.250v VDDC Sapphire Pulse RX 560 2GB BIOS lmk. I can clock my Gigabyte RX 560 4GB to 1480mhz on 1.250v btw.
Hey!
During a research, I’ve made a modification to a PolarisBiosEditor. The modification is called “PolarisBiosEditor-xml”.
I’m not sure if I’m going to develop it further, but it is open source and I hope it maybe useful not only for me.
Dumping into XML-based stdout is done for more data that is not visible in a GUI.
About video outputs, i2c buses, VDDCI-related, generic option ROM headers.
The main intended usage is helping editing and interpreting data opened in external hex editor.
To connect with an external hex editor dumped structures are associated with their HEX offset from the start of VBIOS file.
So to edit some value just go to the shown offset in external hex editor, change it, then open file in PolarisBiosEditor-xml and check that the correct value in the XML dump is changed. Save VBIOS with the editor to fix checksum.

To distinguish the role of a program from other PolarisBiosEditor forks the "xml" is added in a version. It is named 1.7xml.
The source and .Net binary (windows + linux/mono) are avaiable at github:
https://github.com/galkinvv/PolarisBiosEditor-xml
I'm not going to discuss issues, but maybe will accept Merge Requests. Feel free to fork!
The only GUI addition is displaying more columns for VDDCI (only displayed in GUI, no editing enabled)
P.S. There is mining-related Ad link in app (just a link). It was added before me, I’ve just kept it paying respect to previous author. I’m not affiliated with it in any way.
Thank you! Your xml version is really incredible and useful for builds! Thank you for it!
Can you explain how to save xml to file? Because I cannot find any other option then copy paste from command line…
To redirect xml to file:
* Open cmd in a folder with PolarisBiosEditor.exe
* start application with a redirection to a file via >
like
1
PolarisBiosEditor.exe path\to\input-file.rom > outfile.xml
* close gui window to finish application and finalize/flush file writing.
Opening more than one file with redirection woudl lead to catting several xmls from different VBios in same file. This is possible, but don't look useful
bigguygeo, I haven’t enough posts on this forum to anwser your PM. The PM feature is still locked for me.

Returned to this thread after a while. And yes, my TCCDL is currently 4 and I have Samsung memory. Will try 6 and will also try your previous suggestion to loosen either TRCDW/TRCDWA(16 to 17) or TRCDR/TRCDRA(26 to 27). Already have TRP_RDA at 27. Very happy with the mod still, tho I’ve had to come up with a ‘summer fan config’ as I began seeing artefacts in some games in June when the weather became hot enough here. The card sounds like a jet engine while gaming again, but it is completely stable and error-free. Maybe loosening TCCDL will allow me to use the quiet fan config again, or maybe aim for 2100mhz(currently at 2050).
@TheVic1600 it will depend on what type of artifacting you are getting, if its core artifacts the only thing you can do it back down the core clock and voltage, if it is memory artifacts then loosening a few key timings a bit should see you right again or you could make those cooler mods I suggested so the memory is much more effectively cooled which would likely also cure your artifacts if they are indeed memory ones.
I first put TCCDL to 5 and didn’t notice any performance impact. Didn’t have any memory errors either. But yesterday while playing Days Gone, I began noticing green dots in some parts of the game and HWiNFO reported about 30 memory errors. So today I also loosened TRCDW and TRCDWA to 17, which completely got rid of the issue. Managed to play 3h today without any artifacting and without any errors. I noticed the game uses almost 6GB of VRAM, more than anything I’ve played before, which might explain why it artifacted when other games didn’t. I’m not going to try to push the GPU/memory any further as I’m pretty sure I’m right on the limit with it.
Hey guys!
While searching for information on my Rx 570, I stumbled on thread and thank love that i did it!
I’ve seen @ket and @TheVic1600 test configs and memory timings, and this is what i needed to read.
I’m new here in the forum so cant post images and stuff, but i would like to tell my story and see if you guys could help me. I’ll re-read the thread this week and to try to trim the timings on the weekend.
I just bought a used ASUS RX 570 Expedition 4GB, and it got hot. So i decided to learn about radeon software and see what it could do to me, and i was happy to see the Wattman adjust settings. Tried to fiddle with some specs and found something that i was not expecting. My card is now at 1420Mhz @ 1080mv on the last stage and memory is at 1750Mhz @ 850mv, power is +50%, and the fan curve gets aggressive after 60C. Was not really believing the core stability and thought that ive hitted the famous silicon lottery there. I decided to play with Vram frequency to see what i could get, and on Wattman i could not use 2000Mhz without getting errors on HWinfo, decided to leave ate 1900Mhz and was stable until last night, when I’ve faced myself on a black screen. I was really frustrated that i could not see or mess with the timings on my VRAM over wattman, and could not see what I was doing wrong, since i did see some performance gains from going from 1750Mhz to 1900Mhz, but mostly on the benchmark that i’ve been using, which is the Superposition.
I am going to use this GPU to play and record, but was wanting it to hit the bandwidth speed that is expected of 220Gbps, while it’s now doing 160Gbps on 1750Mhz @ 850 mv on the VRAM.
Do you guys have any suggestions or ideas to help me? Do you guys think i can reach those bandwidth speeds? Could the undervolt be stressing the card?
Anyway, this was a awesome read, and thanks for the following attention. I’ll be back during the week. You all have a nice one!
Hi @ramyr0
If you look here you can see that your RX570 has Elpida VRAM. Sadly, that’s really not going to overclock well as it’s the worst sort of memory you can get on any graphics card. The VRAM chips on your card are the Elpida EDW4032BABG. Here you can see they are rated for 1.75ghz=1750mhz, which is the stock VRAM frequency on the RX570. Sadly you will not be able to get these chips to 2000mhz. Even 1850-1900mhz will probably be hard to achieve. Your best bet is probably staying at 1750mhz and tightening the timings.
As for overclocking the GPU Core, run GPU-Z and look for ASIC Quality value in the Advanced tab. The higher the ASIC Quality, the more you’ll be able to undervolt or overclock your GPU. For reference, my RX570 has an ASIC Quality of 72.3% and I’m at 1350mhz @ 1068mv. Your card at 1420 @ 1080mv should have an ASIC Quality higher than mine if it really is stable. I remember I could push my RX570 to 1400mhz with MSI Afterburner and play Wreckfest with it, but it would crash in a lot of other games.
Also, what you’re seeing as 850mv is not the VRAM Voltage but the IMC(Integrated Memory Controller) Voltage, which is also around 800-900mv on my card. The VRAM Voltage can’t be changed on these cards and you don’t need to change it anyway.
Because your card doesn’t have 2 BIOS chips, I recommend following this guide so you can blindly un-brick the card in case you need to after a BIOS flash. It’s important that you have a way to un-brick the card before you start modifying the BIOS. That guide may be for the RX5600XT and Navi GPUs but it works in pretty much the same way for Polaris.
Upload a copy of your vbios to something like mega and post a link, I can then make a bunch of changes for a baseline configuration of sorts for you to work from. Unless you’re playing with some things using a hex editor you really don’t need to worry about bricking your card as even if you use a "bad" memory strap that strap is only used at the defined memory frequency and as we only need to adjust the last few straps for the highest frequencies its not something thats a problem when flashing the card from a DOS prompt or Windoze flasher. Elpida memory blows so don’t even try OCing it by far the best way forward there is to stick with stock frequency and optimise the memory timings. 1.4GHz or so for the GPU core is pretty average for an RX570/580 I wouldn’t recommend pushing for higher as you’ll likely only gain another 30-50MHz and need a lot more voltage to do it, the small increase in performance absolutely wouldn’t be worth it considering you’d be throwing power efficiency out the window and generating a lot more heat. As the card is second hand I would absolutely recommend giving the card and HS a thorough clean and applying new TIM and thermal pads, higher conductivity ratings are obviously better but you don’t need insanely high spec stuff to maximise thermals, something around 8w/m-K for the paste and 6w for the thermal pads will be fine.
