dpcole72 Posted August 23, 2008 Share Posted August 23, 2008 At 5-5-5-18, 2.1V? My mobo is a Gigabyte GA-P35-DS3L (BIOS rev 8F) and my CPU is an Intel Q6600 G0 stepping. The BIOS claims the RAM does 1066 - manual tweaking gets it at 800 @ 4-4-3-9 just fine. But trying to tweak my system's memory and bring down my latency of 73.1ns :eek:, I'm getting nowhere if I use an SPD other than 2 or 3... 2.5 and 2.4 always seem to result in memtest crashes. I've seen everest benchmarks from others; they too have the Q6600 and their RAM latency is around 50ns. More interestingly, if the RAM transfer speed is above 5200MB/s, it'll crash. I AM able to do 1020MHz at 5-5-5-15... but above 1020 memtest fails within 5 minutes; often within 2... I've done tests comparing Everest benchmarks with what memtest thinks the RAM speeds are. Everest puts 8x400 as being faster. Memtest says 340x9 blows 8x400 out of the water. The FSB is volted +0.1 and the north bridge (G)MCH is at +0.2v, as all four RAM slots are populated (each has 2GB). I am a bit thick in this area; why does the SPD setting seem to be reliable only at 2.0 and 3.0? Anything else like 2.4, 2.5, 3.2 won't work and 4.0 is too much unless I use the original 266MHz FSB for the CPU. Thx for any advice you might offer!
