Z68 Extreme7 Gen3 670 sli Problem

[venguard]

I keep reading that Bios 2.22a fixes the problem im having, i have 2 670 in SLI but only one gets detected, i have checked that they both work by putting them in one at a time, iv updated to bios 2.30 and this has not fixed the problem, were do i find this 2.22a bios to check it it works?

I have the same motherboard, and am contimplating purchasing a couple of the 680's soon so i hope you find a solution! Probably a silly question, but; you've definitly got them in the right PCIE slots, right?

Only one of them is PCIE 3.0 (the second one down) and will only run at that speed with an IvyBridge cpu installed, all the others are PCIE 2.0. With my two 470s i have them in the top most slot, and the 4th slot (the middle one).

i got a hold of the 2.22a bios, both my 670s are working fine now in sli. 2.30 breaks it so im sticking with 2.22a which also has a new date then 2.30,crazy
