ROG Crosshair VIII Hero / FORMULA / IMPACT / DARK HERO / EXTREME LN2 OC Guide


Recommended Posts

I tried also this beta BIOS with no issues except the fact that the CPU is running at 4.450 mhz in CB20 instead of 4.500-4.525 mhz all cores with BIOS 3003. No improvement for FLK, still limited to 1.866 mhz.

As a result I returned to 3003.

I've benched yesterday for a couple hours with bios 3101 and an 5950x, seemd fine for first look. Even ln2 switch was working and no stupid high cb (-20C) post issues with it like in earlier bioses.

I've revisited yesterday this bios and it seems my cpu has no CB and CBB at -162C with fclk 1433, board worked like a charm. Best bios so far according to my experience.

Does anyone managed usb working for win 7 on Impact?

I had googled some stuff.
Haven't gotten to it yet.
Waiting on a ps/2 pci card.

Afaik you need to mod the device id for the usb driver so it can be regonized.
Maybe these links will help you.
Please report back if you have found a way to get working.

Thanks for the tips it was good to start with..

Actually found a link for modded drivers to x570 on other forum:

https://retrosystemsrevival.blogspot.com/2019/12/windows-7-usb-3031-amd-x570-drivers.html?fbclid=IwAR0pRDU_ts0rZb5mQ5OsCqM0B6rU5L6dKmvV3XgvufXbXgrKAYMLe2iGItA

But since i do not have an am4 board with ps2 to prepare the install, I've asked a friend of mine to do it for me then simply booted from that pre-installed drive with usb drivers. It loaded a bit for a minute or two but after that works like a charm. Actually on the Impact not much slots left for a ps2 pcie card anyway haha. So credits goes to my buddy @northsys ;).

Benchmarks to come...

 First Run 5950x on Impact / Bios 3101 with IF 1400 Mhz goes ~ - 185°c.... after than I have many problems. 

Tested everything ... all the time ,...I have CB @ ~ - 130°c and cbb with - 122°c

F**k

A hours later the Set/CPU goes best with IF 1900.  🤨😂

Yes... IF 1900 Mhz 1:1 3800 Mhz RAM. 

But I have CB @ ~ - 152°c and cbb @ - 142°c.

 

https://hwbot.org/submission/4658392_mahaudi_cinebench___r20_ryzen_9_5950x_14473_marks

 

Tested with LN2 Jumper ON and OFF. Nothing helps. ...the same...... As if it wouldn't work

Teste many IF Settings.... nothing helps . 😒

 

I've heard this behavior a few times on the Asus Boards.

Apparently they just want to bring the Dark Hero to the front under LN2.

 

Maybe I will test the Gigabyte X570 Master, .... so there doesn't seem to be such problems. There have also been comparisons with the Impact and the Master, and the same CPU runs much better on the Gigabyte X570 Master

That pretty much matches my experience.

It would be nice to have a BIOS that works properly under LN2

I think that's your cpu to blame, i had cpu's that did the same as you describred, and others worked fullpot flawless, did you test the cpu on other board to see if it's specifically board issue or cpu behaviour?

No not yet

I was only told that some of them had the same problems on the Impact ... then immediately afterwards the same CPU was tested on a Gigabyte X570 Master and these problems were not the case

I am having some weird behaviour with the last bios ( 3201 )
Board seem to get stuck on 02.

After flashing back to 2701 it was gone.
Later flashed 3201 again and was able to run it without problems and ran some fclk 2000/4000 mem test.
Tested mem for about 4 or 5 days to see the 02 postcode get back.

Going to try the most recent bios now and I do see that Asus has removed the 3202 from the official site.
So this might have been fixed.

New bios 3204

Anyone else experienced troubles with 3201 ?
Or any problems with the most recent bios ?

Edit:
Tried 3204.
Still stuck 02.
Reverting back to 3003....

Edit 2:

3003.

same shit....

 

Tried 2702. 

You guessed it. No Joy. 

Gonna run something else....

 

 

Edit 48726.

 

I am such a Nub. 🙄

It was the display cable at the back of the monitor which wasn't fully connected....

Ran 3204 for a few days now. 

Anyone experienced trouble with the ln2 jumper resulting in a instant 92 postcode ? 

 

It is too much VDDG_CCD, according to my experience. My CPU does not work above 1.13V. Does not matter with LN2 or normal mode. If i set it manually to 1.2V in Win it always will be equal to VSoc. Otherwise board works as expected on cold:
