I was wondering if anyone has been able to get these running at CAS 6 at all. I have been unsuccessful so far as I can't seem remain stable when running Prime95 Blend. I currently have them running 7-7-7-20 at 1376 mHz on a Gigabyte X58A-UD3R with an i7 920. any input or ideas would be appreciated. thanks.

Try 7-7-6 first. Then 7-6-6.

You probably won't need a DDR voltage bump on the first move, but the second most likely will.

You may also need to bump the IOH voltage slightly (1.12-1.20 - somewhere in-between there), and also increase the vtt/QPI voltage as well.

Maybe try a newer BIOS if you have done so already. The latest one has better memory support.

I'm currently using the latest (F4) BIOS. I have it down to 7-7-6-20 on stock voltage. I've been trying to get up to 4.01 GHz (191x21) but, linpack keeps failing after between 10 and 15 minutes. I think my vCore is fine and my vDimm is at 1.64 and VTT is at 1.34. any idea what might cause this?

Actually the latest is F5. Link

Try increasing your memory voltage to 1.66V (and negate the message it says about going above 1.65V).

Some CPUs don't do well overclocking with turbo mode on. Try using the 20x200.

Also those timings seem a little tight as your sticks are rated at 7-7-7-24. But if the above doesn't work, try running them at their rated specs.
