Doesn't matter what I do, volts up or down, default or manually set, my rig is no longer IBT stable (always fails on 2nd test), and fails orthos too, but takes longer. I even tried dropping fsb down to 300! Any ideas what could be causing this? Latest BIOS/drivers etc. Gaaagh!
system not IBT stable even underclocked!

Have you tested your ram with memtest?

Set the timings to 5-5-5-18-54-12-12-12-12. Thats what I did to get my RAM stable.
Corsair's site doesn't seem to have it listed. It just says 5-5-5-18-2t. It's all set to run off SPD atm, and I've run the memory at way higher than stock with no problems. I have a feeling it's my mobo. But without being able to change FSB voltages I can't really tell for sure.
I've said this about 5 times recently use LinX instead of IBT (they're both based on Intel LinPack), if it's failing on the 2nd test constantly I will bet you it's a bug with IBT.
I once spent 2mths wondering why my i7 wasn't stable even at stock (kept failing on 2nd test in IBT) only to find it was a program bug with choosing only 8 threads, apparently you needed to run 16 threads even though i7 is an 8 thread CPU.
IBT = unreliable.
