Dont know about the SLI set up (maybe you just have a quirky card that doesn't like to be OCd) but my question is, did you get that CPU to 3.9 Ghz on stock cooling? Did you just increase the multiplier? What seetings did you use to get that? I love this 940 CPU, but I am thining about finally OCing it.
i have a custome wate loop im using water bro not stock im at a 18.5x fsb at 211 and voltage at 1.625 some chips run underless voltage on air i would shoot for 3.7 ghz just bump up the multaplyer leave your ht at 1800 if u go i higher u will get more heat out of it
This is an easy fix. The blackscreen on SLI when loading post 178 drivers is caused by you having different bios revisions on your individual cards. Go to your manufacturer and request the latest bios revision for your specific card.
Create a dos boot flash drive, and get NVFLASH. Once you have nvflash on the boot disk, boot into dos and run it. It will allow you to update the bios on each card individually. Boost the pcie voltage to 1.55 for dual and 1.6 for tri sli and you'll be golden.
