First of all i am on a p5w-dh, and am using bios 1101. I am current running at 9x400 fsb. Ram is set to 1:1. Timings are set to SPD. Everything that needs to be disabled is, including hyperpath 3, virtualization.
I am using a coolermaster watercooling kit, and my ram is 2x1gb of OCZ pc6400 rated at 4-5-4-15 @ a max of 2.2v. Powersupply is an OCZ modstream 540W with plenty of amprage on the 12v rail.
To prepare my motherboard i have removed the NB and SB heatsinks and changed the gunk to AS5, the water block for the cpu is also using AS5. And the NB fan that comes with the Mobo is installed.
Phew...now that you have all my information here is the issue. My Vcore right now is set at 1.55v, idle temp is 39 C and load temp maxes at 55 (taken from speed fan and asusprobe, coretemp is quite a bit higher as expected). The issue is that dual prime will run stable for a few hours and then i wont get an error, but the computer will just all out reboot on me. In fact i can boot and dual prime for a few hours at as low as 1.45v but it does the exact same thing. Do i need to give it yet more voltage to get it stable, it just seems very odd to me that i wouldnt get an error, i just all out reboot.
I also have some side questions. I had to set the ram timings to SPD to get the FSB to go above 350ish, computer wont even post with timings manually set. Why is this, if my ram is rated at pc800 at specific timings, shouldnt it be able to do those timings at the rated speed with the rated timings? Another question, my fsb enables ddr1000, which also runs well but at SPD timings. If i DO in fact have to keep the ram timings set to SPD should i go do the 4:5 divider and run the ram at 1000mhz or keep it 1:1 at SPD timings.
Also could it be my bios, what is the generally accepted best overclocking bios. Any and all help is greatly apprciated guys, thank u
P.S vMCH, vFSB and vICH are set to max vDimm is set to 2.2v, and mobo temps never budge from 43C
