Yesterday I've updated the bios to the latest 5843 (I'm using the same 3700x, M.2 SSD as system drive) and since then the Windows won't boot at all, bios won't allow downgrade...set defaults in bios, nothing works, pretty hopeless situation
Can you roll back to the previous BIOS or download a different BIOS version?
 
Yes, probably, CSM on/off must match what Windows was installed with. If you need CSM off for Resizable Bar, you have to reinstall Windows. Sorry.

Regarding the bios in question, 5843, I have been using it for many weeks now with a 3700X and it is rock stable. Haven't had a single problem, and it boots the fastest of all bios versions.

Keep in mind, it undervolts my 3700X so I have to use a positive offset on Vcore to get maximum boost. Works well though, it boosts like a 3800X.
 
New Audio drivers are available:

Version 6.0.9088.1

Hi I just make an overclock in the cpu by CTR, and achieve 4,550mhz with 1,363mv and 4,175mhz with 1,175mv. I am just encontering a problem to ovorclock my ram. the only configuration that works until now is the DOCP, but the only option that I have in DOCP is 3200. All that I have tryed until now dont let the system boot.

I have a good micron e-die kit crucial balistic 3200mhz, and cant go past 3200mhz :cry:
memory model: Crucial BLS8G4D32AESBK.M8FE1
Using ram calculator 1.7.3, and bios 5843.
Any piece of advice?
 
Don’t use the DOCP setting. Just go to the memory frequency section and change it there.
 
Infinity Fabric frequency can't be faster than the memory frequency (well half the memory frequency).

No IF can go to 3600. You want your RAM to 3600, but your IF to HALF that - to 1800 because the real RAM DOUBLE DATA RATE - DDR.

3600 MT/s RAM actually runs at 1800 MHz. So the IF should be at 1800 MHz too. So 3600 MT/s RAM and 1800 MHz IF has the good 1:1 ratio for performance.

I don't have any PCIe 4.0 devices to test it with, but CPU Z is showing PCIe 4.0 bus spec with this new BIOS.

Tnx. something to check, some of first BIOS version also had it but don't recall if anybody managed to use it. I just loaded last best settings I had with previous BIOS.

I used 5843. Both CPU-Z and GPU-Z say that Bus Interface is PCIe v4, but 3080 works as PCIe v3.
One of the past versions of the BIOS allowed access to PCIe v4 x8, but later it was removed.
X470 can use PCIe v4, but apparently AMD does not give that option to vendors.
 
Is anyone having issues with SATA hard drives waking up with this lates BIOS?

I have 3 of the same model hard drives connected via SATA for a parity MS Storage Space pool, but one drive has been dropping out AFTER the computer wakes up from sleep. When I restart the computer, it's fine.

Although all 3 drives are the same model. The one dropping out is a few years older and Crystal Disk Mark says it doesn't have APM like the other two newer drives.

EDIT:

I did just update the x470 drivers from AMD (released this June), so hopefully that'll make Windows play better with the latest BIOS. I shall see.
 
Still having the issue. I just ordered a new drive. It's so only $40 to $50 on Amazon. Not worth the effort to troubleshoot further.

I still think it's related to that one, oldest drive not having APM.
 
Hey,

Just jumping here and mentioning that with 5851 I've been having some unusual sleep issue. I haven't really put time into this but after coming out of sleep I'll get a restart (bsod is set not to restart in Windows). I also have a 3ware 9650 and I think it's trying to put it to sleep because I get a few card resets in a row around the same time.

However if I run memtest, prime 95, cinebench nothing happens. I even did a 5 hours h265 (x265) transcode and causes more processor usage than CPU-z or cinebench. I'm also overclocking a bit, mostly trying out PBO2 and the curve optimizer power band settings:

5800x - PBO2(auto-overclock), Boost override @100 , Curve Optimizer -20 on all cores
Memory XMP 3200 16-18-18-38-56 1.35volts
Cosair a500
I can hold 4700mhz on all cores and about 4950mhz single, cpu-z - 665/6920.

I'm surprised at the stability so far with this board, maybe I can break 5gz if I play more. However I'm concerned the BIOS has some bugs because I also see references to PCIe 4.0 which the board doesn't have.
 
Where did you find that reference to PCIIe 4 ?
