When one of my cores fails prime95 with 8GB's it reduces the system stress just enoguh to let the other cores run for hours. It's a very fine line here.

I have tried P1&P2 off with 8GB no improvement. Even tried crazy relaxed ram timings, still NFG. I know there is a magic combo somewhere to get 8GB stable at 1800FSB I just haven't hit it yet. It's very time consuming because I have to reboot to test, more testing tonight.

Hi, I just happened to read this post as I have been running this board previously with a QX9770 & 8Gb of RAM linked at 1800

I've used 4x 1GB Crucial Ballistix 2000 D9GTS, 8Gb Patriot Viper 2000 SLi Samsung HFC0 & 8Gb CSX Diablo 2000 D9GTR.

All were able to run UNLINKED at 2000 & higher but to run them linked I had to lower to 1800 as the QX9770 refused to do 500FSB (2000).

8Gb Patriot Viper at 2000 9-8-8-28 2.0V NB 1.60 NBGTL -0.08mV
8Gb Patriot Viper at 1800 8-8-8-22 1.90v NB 1.60 NBGTL -0.08mV
8Gb CSX Diablo at 2000 8-7-6-19 2.10v NB 1.62
8Gb CSX Diablo at 1800 8-7-6-19 1.95v NB 1.60

always with P1/P2 enabled

The most crucial part is NB voltage, it needs a LOT of it for 8Gb at high speed

loosen tRC: 50-63 & tRFC: 100-110 to test

Hope it helps, I had mixed feelings with this board, many joys & some letdowns, but what is sure is that it is a challenging board
