removed old DDR3 ram and installed Corsair 2x2 1800 8-8-8-24. Set all skew values to auto. Set 8-8-8-24 2N PL7 all other ram settings auto
Set ram voltage to 1.81. FSB 450x9 333 strap

BSOD

upped voltage a few ticks - BSOD

raised PL to 8 - bsod

dropped FSB to 400x9 333 strap boots fine Everest latency 59.5

Any thoughts?

Thanx

I7 980x 4.43G P6X58D 6G Mushkin 1612 6-8-6-24 1T EVGA GTX480 826/4200 Noctua DH14 Corsair 850W PSU 2 - 1TB WD HDD, 1 600G WD Vraptor for FSX Thermaltake Armor+ Case W7 64 Pro.

Ram voltage is 2.0v

Did you leave everything else the same or did you set CPU GTL and NB GTL back to AUTO?

Do they have the settings listed at Corsair for this board?

I cant look at this right now but will try later today

Wasn't sure how the skews would affect things so I reset everything and just set 8-8-8-24 2t - everything else at auto.

Memtest failed a the start.
AFter sleeping on it I decided to try leaving the settings as I had with Mushkin, including skews. Upped voltage to 2.0

currently running memtest86 with no errors so far!

no answer on any settings from corsair forum yet.

Possibly I was being overly cautious in resetting everything. Gotta go out for a few hours so I'm letting memest do it's thing

theres your problem

You should have left everythng EXACTLY as it was except reset GTL's to AUTO, set memory voltage to the Corsair MAX (which I think its 2.0 on those sticks.).. and if any errors appear, THEN set those GTL's back to what we established for the mushkins cuz for the VTT those are the correct GTL's (you can run those GTLs if you want anyway)

If its stable and you are running the GTL's leave it... those are correct for the VTT we set

I'm sure you probably solved your problem though... let me know if you see anything screwy but with the base voltages we established and the 2.0v memory voltage it should run stable

You probably wont get 1T and I know PL7 is the best they will do at 1800 but you can try for 1T after everything else is proven stable

So far so good - memtest stable after 3 hours. Know the cpu clock is ok so now I'll try blend tests.

ok - OCCT custom mix test stable for 2 hrs.

So far so good.

I was able to run PL6/1T but during OCCT mix tests it crashed after a while. FWIW, difference between PL7/1T and PL7/2t is read is 11000MB/s with 50.5 latency at 2T/7.

Understand. Flew online for almost 2 hours last night with no issues at all. I plan on sending offerings to the memory gods daily!

BTW, LOVE the GTX 280. Surprised that it runs so cool but it sure is big, Even in my large Kandalf case I was moving cables around to get it in.
