Interesting. When i disassembled by Crosshair VI Extreme for first start i got Q-Code 8 (and later Q-Code 9A) and have to remove backplate as part of troubleshooting, but it wasn't glues. There just few lines of hard plastic insulator.

Inspect PCB on damage. If some traces on PCB are damaged it may cause board to do not post. Signal can't jump over damaged part.

Data from LED also be helpful (CPU LED, RAM LED, e.t.c.).

did I brick the board?

Hi, all I gave my old crosshair vi hero to my ex-wife when I put the system together I installed a cooler master hyper 121 CPU cooler. I had to take off the backplate to the CPU socket it was glued on so I pride it off with a screwdriver when I got the system together it would not post q code 0d. then I got her an MSI mag water cooler when I was putting that on I put on the old CPU backplate I noticed that the adhesive insulator had some wholes in it from the screwdriver. I tried it anyway this time I got one long beep and two short beeps and q code f9. did I brick the board?

Zewspeed Thank you for this excellent post as well as your follow-up to Sandman!

This is exactly the information I needed as I'm running a Corsair H100i v2. I actually had some sort of conflict between Aura & iCue a couple weeks ago that resulted in the pump and fans turning on and off every few seconds, though that appears to have been strictly a software issue as it hasn't come up again after updating both.

I don't believe I'd miss the particular setting you mentioned from 7201 as I haven't experienced coil whine (or the environment I'm using my PC in has enough background noise to prevent me from noticing). Same goes for performance bias, at 1440p my GTX 1070 Ti is the bottleneck.

Thank you and +Rep (hoping it still works w/migration)

My 2700x/B-Die does best on 6401. Tried up to 7601 but came back and won't try any more with this chip. It feels too good not waiting for yet another Bios with hopes of any improvements for 2xxx series.
Thanks! 6401 is another excellent release, working fan control + all the goodies like 7201 for the 1000 series too.

Thing is, in my experience the newer Zen2 AGESA based BIOSes are better behaved when pushing the limits of memory OC vs the PinnaclePI based ones like 6401. When I was still using my 1700 some pretty tight memory settings would sometimes need a double boot on 6401 to POST whereas the exact same settings on 7201/7704 would always POST on the first try. This is on a cold boot, not previously being powered on. Not really a problem, but it's something to point out. Never had a cold boot failure on the Zen2 based BIOSes.

To recap, for the 1000 series 6401/7201 provide "the full package" and 7704/7901 are a good choice sacrificing some things necessary to eek out the last drops of performance out of these CPUs.


2000 series are completely different in their behavior and peculiarities, never had one so I can't comment on them.

Quick background: I'm using a Ryzen 7 1700. Put 7403 on my board a while back, other than the weird double-boot thing it does sometimes it's been stable with a mild overclock.

If you want full compatibility with the 1000 series regarding tweaking abilities, then install 7201 (AGESA ComboPI 1.0.0.2). It's the last BIOS that has properly working performance bias (+3% IPC from the 2000 series) and the full AMD CBS menu, but fan control is broken. Minor or major inconvenience depending on you using an AIO cooler or something with a pump. It's also the last BIOS that lets you set power supply control to typical idle vs low current idle, this solves coil whine at idle with cstates enabled.

All the 73xx-76xx series BIOSes don't have the proper performance bias settings for the 1000 series and don't have the AMD CBS menu enabled on these CPUs, so you can't do any proper tweaking nor do any Pstate OC. These behave weirdly, too, so skip them.

7704 (AGESA ComboPI 1.0.0.4b) works fine and so does 7901 (AGESA ComboPI 1.0.0.6), both having working fan control, faster boot vs 7201 and all, but then you can't use performance bias, and these don't have the power supply control option exposed in the CBS menu. If you have idle coil whine then disable cstates, power consumption at idle will be a few watts more, but nothing more.

IMO, 7201 if you don't have an AIO cooler or a water pump, else 7704/7901.

HeroofTime Thank you all for the replies in regards to the CSM bug and the sleep bug.

As for RAM speed limitations, why wouldn't one simply compensate by tightening timings versus aiming for faster speeds that aren't allowable by the board?

But it will be interesting to find board DDR4 limit anyway.
DDR4-4500 is achievable on this board, but i doubt this frequency is usable. Probably, smth like 4266 would be it`s limit, like with X470 Taichi.

By limit I define not only stable overclock on chosen frequency, but also the ability to tighten the timings on that frequency.

I have another problem with the board: its memory settings are limited by 4000 and only with biosmod you can go further
