First kit I'm testing is the blue Cellshock DDR3-1866 CL8 with D9JNL chips, it's the same kit CryptiK is using.

This is the highest 32M-stable speed I managed on CL7-7-7-14 1T, VDIMM is 2.04V:

Now I'm working on CL8-8-8-24 1T, but I can't even get it 32M-stable at 1000MHz with 1.90V, with the same subtimings CryptiK is using. Even on 2T with even more relaxed subtimings it's impossible.
The specific DRAM skews that worked well at CL7 don't work at CL8.
What's your secret?
Heh you mean me? Nothing really, just straight run boot from BIOS with the settings you can see. No idea what I have vNB set to for low FSB/ram around 1996 MHz, I think 1.43v for memtest stability.

I don't use ram skews though, just leave them on auto.

Memtest would always error out after a few passes...

For high clocks seems the 266 strap is favourable on my board. This REX is in 3D better than my previous one, but FSB is fully blocked at 635... bummer
Where can I get BIOS 0002? It's not on the FTP. 635 FSB is pretty nice, my CPU tops out before that so I have no idea what the board limit is.

When you are running 610 FSB + what vNB are you using? Do you just have stock cooling and if so what is your NB temp at. I find it impossible to keep it under 56*C load with stock heatsink & MX-2 with a fan on it.
