Vdroop is a fickle thing with the Aorus boards. I’ve actually noted an improvement but I always set the "High" LLC setting anything above that is just overkill and will overwork the VRMs. I wouldn’t count your IMC out either I achieved superb memory overclocks on the Asus X370-F I hit 3466MHz out of the box with firmware 3402 didn’t need to do any more than switch the memory divider. In contrast I have to fight the Aorus every step of the way for 3466 and fight it even more for 3600.
Heads up guys I’m also not switching back to the Gaming 5 now I’ve finished modding F22b firmwares so while I will continue to make modded firmware it will be done "blind". Also starting with the completion of F22b firmware mods for the B350 boards firmware mods will be DROPPED for the following boards; B350 Gaming, B350 Gaming 3, X370 Gaming K3. Modded firmware previously made for those boards will of course continue to be made available for download.
A bit of daily news guys, anyone who may come to this thread but also owns a Biostar GT7 Biostar have now released new firmware based on AGESA 1002a. I know I’m not popular with Biostar where I kept prodding them about this (and the easy to solve bugs with their firmware) but they are still head and shoulders above the likes of Gigabyte.
EDIT: All modded F22b firmware is now up

Looks like Gigabyte has just released new F23d firmwares based on AGESA 1002a, as well. Plus, there are now X470 firmwares available if you want to compare them to the X370 ones.
BTW, I used Q-Flash to flash your K7 F22b firmware and it’s working like a charm. I really appreciate how many settings you unlock, and how you organize many of them more sensibly than the original BIOS. Thank you! 
Ket that biostar is a mighty fine little board, i love the layout and the racing flag scheme, gonna have to get one of these next weekend.
wow on my taichi at 3333mhz the latency is 57ns

Yup, just seen it myself too. Once again I’ll be forced to redo all of the edited strings for -D firmware because GB keep changing them for no feking reason (getting seriously pissed off with that)
. Just when I thought I could leave this turd I’m gonna have to stick with it a bit longer while I mod some F23d firmware. At a glance it does not look like GB have fixed or added anything with F23d but I’d be extremely surprised if they have not fixed the HPET bug. Be nice if they could get off their arses and fix the bugs in the firmware I’ve been having to fix for the last year as well but this is GB, they slap shit together and don’t test or debug any of it. If GB Matt is to be believed all GB do is whine and complain to AMD "too buggy", no GB, the AGESA code is not buggy, the bugs are your doing and fault they do not plauge any other manufacturer.
Dont be fooled by looks! the asrock taichi is the number 1 board by a mile for amd and intel, if you get this board you will get the best out of your hardware make no mistake about that, it has the best power delivery i have ever seen on any motherboard ever, thats where the moneys gone with it, if you buy this board you wont have any of the stupid problems that gigashite keep presenting to their customers, i dont normally waste my time recommending motherboards but the gaming 5 or k7 arent even in the same fucking league here fella. My memory runs 10ns faster, my cpu temps are 9c lower and the board itself runs much much cooler, simply because it can cope with power… also unlike the gigashites everything works properly even from the very first bios release, Asrock have released 4 bios updates already this year and every one just keeps getting better and better, ive got memory multipliers ive never seen on any other ryzen board in 150mhz increments, where as with gigashite, their bioses have only got worse! to the point they are going backwards.
This company actually cares about its customers and it listens! nah though seriously theyre not even in the same ballpark, ive had not 1 single issue with this its bloody great. It has a monstrous amount of settings in the bios it aint a board for beginners, and yes even the 2 zone led software works 100% perfect. The taichi’s NVME raid is blisteringly quick actually doubling throughput, very very nice boards.
Please save yourself the agony of wasting anymore time on this piece of dog shite, its not even worthy of having a ryzen7 installed in it. Anyhoo if you dig around you can pick one up for £160 and it will be the best purchase you ever made, in fact to tell the absolute truth asrocks budget ryzen boards are still way better than anything from gigashite. so yes the taichi is the one to go for not even top end asus boards can match it. Ive overclocked the snot out of mine and the vrms get barely warm to the touch.
I havent even started with watercooling yet as you can see from the pics, soon will be adding a pump either side and watercooling the graphics and cpu separately, and btw even with a decent air cooler you will hit 4.1Ghz easy on the r7 1700, ive fitted 2 x 360 rads ready though so im ready for hardline tubing might go with glass or copper tubing as my brother is a plumber lol!
Wait a minute here, youve got to pump 1.41v into your ram to get 3360mhz? jesus christ i run mine at 1.33v at that speed.
Modified F23d firmware is up for Gaming 5 and K7.
I hope you’re all sitting down for this news but… GB have actually done some work for F23d, I’m yet to test how much actual work they have done but for the first time in a damn year advanced memory subtimings are displayed correctly in the UEFI.
Ket youre a fucking star for looking after these people. well done gigabyte its only taken you 13 months
Thanks for the feedback. Yeah, I hope the X470 Taichi then follows in the footsteps of the X370 Taichi with the quality. I don’t think the X470 Tachi Ultimate will be worth the extra features for me though.
I am experimenting now with making small mods to my case (Coolermaster CM690 III, I made my own plexiglass sidepanel attached with magnets, and removed the top 5.25" drive bay cage), so the LED controls are welcome. Just a pity the X470 Taichi doesn’t have a 5 pin LED port, so the RGBW LED strip I got will then probably just function as a RGB strip and leave the white LEDs off. Hopefully it fits… Your case looks great, I am sure it will look even better once you are done with it. I don’t think I will go in the direction of custom loop water cooling though, seems like a lot more maintenance than just taking a leaf blower (of sorts) to my PC twice a year for one minute.
My H100i V2 struggles quite a bit with temperatures if I try to go any higher than 3.8GHz on my 1700x, so I decided I prefer the silence more than the extra 100MHz I could still get out of the CPU. We’ll see what the temperatures are like on the Taichi, hopefully better.
If only I could get a board for that much… Living in Namibia has some downsides, and prices for technology is one of them. An X370 Taichi would probably cost me somewhere in the range of £240 - £280 here (using current exchange rates). Hopefully the X470 Taichi won’t be more expensive. I paid around £210 for my Gaming 5 in April last year.
Hey @all
After a clean-install + F22b (Thanks to @ket ) all is much much better!!! Really stable OC @ 3.60GHz ~1.248V… FlareX @ 3400 MHz 14-14-14-22-36 CR1 ~1.414V… BCLK @ 100.10Mhz STABLE 100%… AMD GOP working 100%… FastBoot 100%… Kingston Savage SSD - 560/540MB/s (R/W), 33/113MB/s (R/W) FORCES AMD SATA AHCI Drivers v1.3.1.267
NO BSOD WHATSOEVER!!! I must say that GB really fell behind here… I agree completely that @ket has done freaking wonders faster & with actual results!!! Cheers mate!!!
You’ll have a shiny new firmware to try at some point today as well 
I haven’t done anything more to these firmwares other than diagnose the problems, continuously plug away at GB with the problems, fix a couple bugs myself, clean up the firmware so it doesn’t look like an intern made it, expose a swath of options so the board actually has basic functionality, and expose some options so the board is a semi-capable overclocking board. Hmm… ok, thats actually quite a lot now I look back at it lol. I would not consider it coincidence either that memory SPD data reading is suddenly fixed it’s a bug that was fairly high up the list on the bug report I sent to my GB contact. Hopefully the people he passed it to gave GB R&D an almighty kick up the backside for their sloppy work.

I take an air jet of sorts to my PC as well
Its meant for blowing dust off the Harley but it works great on the PC too 
That H100i should be able to cope with a 1700X easy I use a modded Master Liquid 240 and I never see temps over 50c even in hot weather @ 3.85GHz 1.35v unless I’m running scientific applications like BOINC SETI@home or milkyway@home projects (superb stabillity testers, if your CPU is BOINC stable its everything stable). You might want to hold on to that Gaming 5 for a while before plunging for a new board if GB continue to actually fix bugs theres a danger in a month or two it won’t be a pile of crap.
To be honest I expected the H100i to do a bit better in my case. I use Prime95 to make sure that my system will stay within temperature constraints no matter what load I put on it, and Prime95 (and AIDA64 FPU stress test) seems to push the temperatures up the most. I actually have to have the fans look at the CPU temperature instead of the water temperature in those cases, because otherwise the CPU would overheat way before the fans have a chance to spin up, since the water temperature rises too slowly (even if I have the pump run fast). So I have a separate Corsair Link profile when I encode videos that then switches the fans to look at the CPU temp, then I will get around 60C to 75C on my CPU. Prime95 will bring me to around 80C or slightly higher, but still under the limit of 85C. At 3.9GHz I struggled to stay under 85C with Prime95. My temps at idle are in the 30C - 40C range I think, where I then see those regular temperature spikes that seem to be common for Ryzen. I can’t remember my voltages really, but I use low-ish voltage along with Extreme LLC so that the voltage doesn’t drop too much.
Unfortunately the one issue I have (Sound Blaster Z) cannot be fixed with a BIOS update, so I will have to try to sell it as soon as I see my Taichi is stable.
Honestly I’d just invest in an Xonar card, way better than that SB crap and far easier than messing around swapping boards. You could also harass Creative about the problem its a bug in their drivers. Their drivers are riddled with bugs though so you really don’t want to touch Creative cards with someone elses 100ft barge pole. EDIT: was also going to mention but had to cut the reply short that you will always run the risk with a Creative card on any mainboard of it not working right as the fix Creative should be making to their drivers was put on board manufacturers to implement in firmware because Creative suck so you will always be at the behest of a board manufacturer being bothered / remembering to pick up Creatives slack each time. BOINC projects like SETI and milkyway are better for stability testing as well the calculations are just far more complex so stress the CPU in many more ways than something simple like Prime or AIDA will.
Ket,
I flashed your F-5 bios to my AX370 K-3 board and it seems that I cannot get the RAM to stay at 3200mhz. Some times it does run there and other times seems to down-clock. Was wondering if the latest bios for F-22 would be better? Also wanted to know if you have a primer on what settings should be changed for a stable FSB. I’ve seen you make suggestions on stabilizing the voltages, so any information without reading 39 pages of this is welcome. I use this as a HTPC only and am looking to maximize the performance with stability. A mild overclock at best.
Thanks,

I would switch to F22b it should solve your problem. FSB does seem to be a bit on the dynamic side by default its just how Zen appears to operate with my modded firmware I disable spread spectrum which leads to the FSB being a bit more stable but without an actual clock generator chip theres not much which can be done to try and set an FSB speed more consistently.
Agreed ket, somethings wrong with that corsair cooler that belongs to mach5, i can hit 3.75Ghz on the stock cooler! 4ghz should be no problem peaking at 68c on that corsair, there is a setting in CBS/Power States that enables/disables throttling try experimenting with that m8.

Good news for you sir, i can indeed confirm the wonderful soundblaster Z soundcard works awesome in the taichi board, i tried it last weekend for some FL studio work. support for the SBZ was added with bios v2.30 which was 10th may 2017
here is a list of compatible soundcards for the asrock: https://pcpartpicker.com/products/sound-…ble_with=fZKhP6
And remember guys its taken gigabyte over a year to sort the most basic of problems, at that rate it will be another year before they are all fixed.
i use your modified f23d for Gaming 5, but the sub timing for the memory still not displayed correctly (it still display default 2133 MHz subtiming)
thank you
