Hello, bought some new ram Adata Vitesta Extreme Edition ddr2 800, rated 4-4-4-12 at 800mhz by manufacturer. Should oc to 1000mhz fine with some kind of ram timings, not that I'm trying that. My mboard is Gigabyte 965p-ds3 (v1 or 2, can't remember, will find out if needed) Bios version F12. My cpu is e6400 oc'd to 3.01ghz (stock hsf). Fsb is at 376 to achieve this (with 8x multiplier). When this setting is in place, my options for the memory multiplier are 2 (which sets the frequency at 752mhz) or the next increment up is 2.5 (sets the frequency at 940). System will boot with the SPD timing settings with the memory multplier at 2.5 (940mhz), the SPD timings show in the bios as 5-5-5-18. It boots fine, ran a half hour of memtest, seems ok, but for some reason it's showing as 7-7-7-20 in the memory tab of cpuz. System will not boot with multiplier @ 2.5 (940mhz) and timings at 4-4-4-12. Which is to be expected, no problem there. I just want to get it running at 800mhz with timings at 4-4-4-12, the hardware is definitely capable of doing this. I don't want to try to change the fsb, I already tried once, set it to 390 (which still only gives me 780mhz ram) so the cpu was now 3120mhz, but it wasn't having it, no boot. Anyway I'm not trying to further OC the CPU. So the questions are: Is there a way to get it going at 800mhz with 4-4-4-12 (without ocing the cpu more)? Is 752mhz @ 4-4-4-12 better or worse than 940mhz @ 5-5-5-18 (or 7-7-7-20, which cpuz is showing!) ? Should I consider getting after market cpu hsf to push to the fsb to 400 or beyond? (this would allow me to get the ram at 800 4-4-4-12 but would push my e6400 to 3200mhz)?
