Corsair memory advice.

[MagicUK]

I've got an asus sabertooth x58 and memory set up is abit of a strange one.

I've got 3x2gb corsair dominator 1600mhtz and 2x8gb corsair vengeance 1866mhtz running both at 1.66v and 1604mhtz, now the 3 dimms are running in tri channel and the 2 vengeance are running in dual channel, does this board even supports dual channel? Also the corsair vengeance is showing (CMZ8GX3M2A1866C9) in cpuid, is this ok to run at 1.66v 24/7' I'm currently running the system at blck 160x23 which I think the system is running at a little over 3600mhtz(i7 950) it's been running prime blend stable for 2 hours as we speak, how long shall I be doing before I class as stable?

Yes, the memory controller supports dual channel as well.

The vegence is rated for 1.5v but "should" be fine running at 1.65v. You could always try setting the voltages to something like 1.55v and see if the Dominator is happy running that low.

Usually I would say leave Prime95 to run for about 8 hours before classing it as stable other people prefer running it for longer though. Another option is 20 runs of IBT to check if it's stable, but I prefer Prime as the blend test also checks RAM stablility as well.
