Yes, I climbed up to 1.20v, as is the maximum recommended for 24/7?

With dreams GTX460 is stable to 1.48 v, and when I have the two seats, but it go to 1.55V is not stable ...

NB I have always to 3000MHz @ 1.35 / 1.375V.

And if course, use the sli patch hack.

I'll try to raise the HT to 2400MHz and see what happens.
Try 1.4v on the CPU-NB your northbridge might be under some considerable strees

I placed the 2 nd GTX460, and changed several things.

I turned up the HT, 2000 @ 2400 @ v 1.26
The CPU-3000MHz NB @ 1.40 v
And the NB voltage to 1.22 v.

I will try a prime95 ...

WOW, 5 seconds 1 core fail.....xD

I would try to use 1.5V on the CPU and try from there, if not then your mobo may some how be turning you down and try a 890FX mobo or downclock your settings just a notch

I do not think it is for vcore ... With a single GPU is stable at 1.48 to 12h prime95.

I tried to raise the voltage of the HT and NB I went up to 1.30 v, but it gave me BSOD 124.

Yup but all your components are getting a considerable amount of strees with your overclocks running and a sli card just been put into gear so there's more demand for power and your CPU might not be getting all the amperage it needs, try 1.5v and see what happens, if its still the same then you may Need to downclock a little

Than the only thing I have for suggestions is to either upgrade to a 890FX chipset motherboard and hope for the best or downclock your CPU and NB just a notch and go from there
