Hello all, I'm very pleased that I'm joining the Nova club. I've only ever used Asus motherboards in all my previous builds so interested to see what ASRock have to offer.

I thought I'd start with trying to dial in my memory overclock first, trying to target 6400Mhz ideally, and using the AM5 Hynix Guide here as a starting point but I'm hitting a bit of a wall and I'm only a few hours in. As soon as I set my memory voltage higher than 1.44v the system refuses to boot, even when keeping all other timings and settings the same. Is this the same bug talked about earlier in the thread that we are waiting for a fix for?

What's worse, is that when it does that it seems to reset my secure boot/TPM somehow so I have to go through the Bitlocker recovery shenanigans over and over again. A message about fTPM flashes up for a brief moment but disapppears. In the past I've always used a discrete TPM but is this just now a fact of life overclocking when using firmware TPM/Pluton?

Still getting used to the new AM5 overclocking process and the voltages but this is where I'm at the moment:

9800X3D / Corsair Vengeance 2x32GB @ 6400CL32 (cmh64gx5m2b6400c32)

VDDIO: 1.20v
DRAM VDD: 1.42v
DRAM VDDQ: 1.42v
DRAM VPP: 1.80v
SoC: 1.25v
VDD Misc: 1.10v
CCD: Auto
IOD: Auto
VDDP: 0.95v

I've figured this out now. Apparently my memory has a 1.435v limit on the memory and that is why the board refuses to boot with anything above that. It doesn't look like there is any way to override that (don't see an option for high voltage mode?), although I think it should be enough as I'm not chasing crazy frequencies and targetting 1:1.

One other curious behaviour is I was initially happily stability testing at 6400/3200/2133 while tweaking the timings, using the above voltages (VDDP bumped up 1.05v). However, now even with loose timings I'm getting all sorts of errors quickly unless I have vSOC at 1.26v, and I'm not sure 2133 FCLK is going to work anymore. Is it possible that I could have degraded my chip only within a couple of days? The stability testing was Karhu and TM5 1usmus config.

No, rather not. 6400 and 2133 need voltage, also depending on the timings. Don't expect that low SOV voltage such as AM4 is sufficient.

AMD DDR5 OC And 24/7 Daily Memory Stability Thread

https://www.amd.com/en/technologies/expo Soon to be released EXPO AMD optimized DDR5 memory. Likely as with Intel memory, A-die will be preferred. M-die is a close second. It has been said that like 3800-4000 1-1 the sweet spot for AMD 5000 series CPUs, 6000 1-1 should be the sweet spot...

A thing which frequently bothers me with my Nova is that the Board/Bios frequently confuses/changes the boot disks.
I have two EFI disks with bootloaders in my PC (which hosts 3 x Windows). One is the main bootloader, the other one is a backup. Via bcdedit I named the backup one accordingly, so that I can see, from which EFI disk the (first) one was loaded, when I see the (black) boot menu.
My Nova has a strong tenendy, when I enter the bios/uefi that it changes the boot order and sets the backup one as the first one - without letting me know. I don't want this sequence/order change and I frequently change it again manually and safe it to my profile.
Next time when I enter the bios and do NOT open the boot page with boot sequence, I can almost be sure, that the boot sequence was changed after the following boot.

Anybody else maintaining two EFIs + bootloaders and facing same issues?

All my BIOS settings. This passes KARHU RamTest 40000%. :) The website won't let me use an Imgur link AND won't let me use Spoiler around the pics to stop the wall of scroll. :(

Is this the optimal performance and stability on these settings that you showed here? I just use them on the same board paired with 9800x3d. Can you recommend anything else in the BIOS settings for the best and most stable FPS in games? Thanks in advance!!!

Updated settings on my Taichi.

I raised the voltages as even though it passed Karhu RamTest and even Core Cycler and y-cruncher, sometimes when I was opening multpile tabs from a website, the original tab I was opening from crashed and closed. It no longer does that.

Hopefully Asrock comes out with a bios soon with AGESA 1.2.0.2b so we get to try that too.

Buildzoid just bought the X870E Taichi Lite - at first I thought because he's has real interest in it - but it maybe he's just rambling about it (haven't watched it to the end yet):

Anyone with a 9900x and 2x32GB running 1:1 6400 that can share any potential hints? I can't seem to budge past 6200, from initial investigation / trial. Still have to get more into the weeds (coming from Piledriver), so to speak. On Taichi, latest Beta, using EXPO.

VDDGs at 1.1v/1.0v help a ton. My RAM won't even boot without that.

Can you please let me know what the default values of VDDG CCD and VDDG IOD as set by ASRock on the Taichi for the Ryzen 9000 series? Ryzen Master is barfing so I can't look at the values (Zen Timings doesn't list it). Thx!

Anybody had bugs with bios settings that were previously disabled just enabling itself again?

I had iGPU disabled and for some reason it enabled itself recently. Also had a bunch of virtualization/security stuff disabled that also got enabled for no reason.

Well there is 3.15 for some boards....only motherboards company that I know not giving new BIOS to top products first.
