is it BIOS 3501? it has been in beta for close to 2 months already and I only want stable version 😔
No, is the 3402! I never use BETA bios! One problem though, but maybe is Windows, I have a problem and crashes using my 64GB 2x32GB Corsair 3600MHz RAM at his XMP speed. I have to leave it at Jedec specs 2133MHz to be completely stable. And it's weird!

Hi everyone, sorry for the bump but I couldn't believe my motherboard didn't support SLI and also couldn't believe someone had figured out how to get around the SLI cert issue.

I tried following the pdf steps by getting SLI cert from my donor board, but I cannot seem to figure out where to insert it into the dsdt for the other board.

My first attept I got ACPI error bsod. Second attempt there's no PCIe devices anymore.

Can someone help me figure out where exactly the cert goes into my DSDT file?

Hello, this is a pretty old thread - I suggest to create a new thread instead.

Don't forget to include your hardware spec (motherboard brand & model, GPU, and anything else that might help).
