It's like talking to a brick wall

Linpack calculation errors like in his pic are more than likely CPU GTL1/2 or NB GTL related, I've told him this too. Since CPU GTL1/2 can't be adjusted seperate of CPU GTL0/3, he is screwed basically so he needs to back off settings till its stable.

CPU GTL1/2 wants to be high, CPU GTL0/3 wants to be low, you can't dial both in low and expect stability, only other alternative is raising Vtt and balancing it out.

I can replicate those type of Linpack errors on my DFI board simply by changing GTLs by as little as 0.0008v sometimes, and this means one of two things. First most likely my Vtt needs some minor adjustment, or second I've found where the max or min threshold for logic receiver GTL sampling lies.

You can't test GTLs with a tight PL as well, need to be done with at least PL-2 lower than aimed. That way takes strain off MCH, and if Vnb was too low it won't trash your results. CPU multi should be dropped as well by 1 or 2x. To give a frequency that'll work on VID for testing.

That's exacly what I meant before, quads with high clock + mem with high clock + low performance level probably will no go.

Definitely mate.

On my previous RF i ran a Q6600 G0. It walled at 481mhz FSB, I ran that every day...but I only ran on 7x multi so 3.36ghz, PL7, and 1158mhz ddr freq. Board threw fits if i tried 8x and 481. It didn't like it period.

There is one among us with a C2D and he has the same problem.

Ooh... If this is the problem ASUS would have told me that.
I tell you ASUS is trying to fix this problem but doesn't really know how to. BIOS 0902 should have been released a few weeks ago but they didn't because the problem isn't fixed. They only released it because of the fan mail that they received lately.

With 2x2 or 2x1?

With the G.SKILL F2-9600CL5D-4GBPI of course.
