So far so good with my ROG CrossHair VIII Formula and BIOS 3402.

Baio

v3402 avaliable also for ROG Crosshair VIII Formula.
Yesterday was signed as beta, today I found it in Asus italian website marked as final... the 2 files seems identical, does anyone know if it's...

Yes of course... forgot to write it.

Baio

Samsung 980Pro + WD Black SN850 + 5700XT, all running fine @4x on my Crosshair VII Formula.

Baio

Very strange... I solved this issue a couple of times just reeating the RAM, but I suppose you already tried it.

Baio

I read only critics about this release... I must say that IMHO is one of the best I've tried.
I swapped RAM kit (both Corsair B-Die) along with installing the new BIOS and I can set them stable...

Thanks!

Baio

I suppose it's not official, isn't it?
I mean, it's an unofficial beta... I can't find it on Asus website but 3102 beta is present.

Baio

Not from the italian site... still there.

Nor the Crossahair VIII Formula? Only the Dark?

This can happen as Calculator does not calculate well everytime... each system is unique ad sometimes you have to tune some value on your own.
Try to follow what I wrote in my former post that is...

I don't have a Zen3 CPU, mine is a 3900XT but I can tell how I reached 1900 IF 1:1 with 4x8Gb RAM.
Setting BIOS as suggested by Calculator gave me great instability and reboot problems, so I put all...

Don't know if is a D3 error... I just read "CHECK CPU" in the dashboard... but everything works fine.
This behaviour is present untill BIOS 2501.

Baio

Ok, so I can confirm I have no WHEA error after resuming from sleep, only the inbuilt LCD display of the mobo that shows "CHECK CPU" message instead of CPU temperature.

Baio

Found first issue for BIOS v3003, when waking from sleep the inbuilt display of the mobo gets stuck on "CHECK CPU" instead of showing the CPU temperature.
System seems to be fin anyway, how can I...

Really strange... I’ve just updated to 3003 (I had Aura installed) and RGB works as usual...
Did you flash using the Flashback option?

If so, I think your mobo needs a RMA.Â*

Did you try to reflash the BIOS?

Thumb up for me... only thing I had to raise 0.01v of my DRAM to make them stable.

Baio

Thanks for this 'little guide', they are all known piece of information, but having all of them in row it's very usefull.

My experience can unfortunately confirm all you wrote... I've passed from...

Gonna give it a try... but disablilng it means the CPU is always stuck at maximum power consumption?

Baio

An still no solution around! :(

Baio

Still testing, but seems ok... obviously as this RAM is rated 17-17-17 @4000Mhz.
Why BIOS 2701 (beta) and not 2702 (final)?

Baio

Hi Uplink,
Thanks for your help.
I went through all the steps you listed, RAM gets set to 18-17-17-17-37 instead of D.O.C.P. 17-17-17-17-37, according to both CPU-Z and DRAM Calculator.
Obviously...

Thanks for reply.
No, they are 4 sticks of single rank RAM, according to Thaiphoon.

Baio

Those BIOS drive me nuts... :(

Here's the story so far... had 2 kits 2x8Gb of G.Skill, 1 was 4000 and one 4133. Worked smoothless @3600 CAS14 until BIOS 2206, then no more luck.
Sold the 4133 kit...
