hello I have two sets of this ram in a EVGA 780i SLi A2 P08 BIOS version motherboard.

I have a wierd problem when I run memtest on just one stick of these it errors out unless I set it to a lower speed. (I have it set to 5-5-5-15-2T 2.0 volts DDR1000 which is EPP#1)

BUT hen I have all 8Gb in it doesnt error why is this is there a better way of testing? Maybe a different configuration?

did you run it with 1T?
and are they the same settings between 1 stick and 4 sticks?

thank you for your reply should this set be ran at 1T? the specs say 2T. I will try that with 8GB. Usually when I run any ram, especially 8GB it doesnt work correctly.

[Jonilink]

i used the exact same settings for both sets weither using 1 2 or 4 sticks. 5-5-5-15-2T 2.0v

I have also tried 2.1 volts

Yesterday I let the comp sit over night testing just 4GB of ram both kits ran for 6 hours no errors.

[Jonilink]

ok just tried 1T command rate with one stick at a time and at DDR1000 it would not post
but a DDR800 it did post and every stick passed memtest so one stick at a time will pass memtest. I also tried one kit (2x2GB) and sam thing at DDR1000 and 1T no post. Then I set the ram to DDR800 and it would post I ran memtest and no errors.

I decided to play Farcry 2 and it ran for about an hour till I got the nvlddmmkm.sys blue screen so now im back where I started lol

Anymore ideas?

Is there a special configuration to get 8GB of the ram to run on a 780i Sli A2 motherboard?

[Jonilink]

I tried also using 8GB at 1T and it wouldnt boot only works with 2T

our rated spec is 2T, not 1T, so 1T is not guaranteed by us
and running with 4 sticks, you may need to add FSB volatge to make it stable
thanks
