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 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 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:

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.

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.
