well 1st off what a great chip this E4 sandy is....

currently at 2.8ghz at stock vaultage (actually a little over according to my asus probe - 1.42 - 1.44 vaults.

further to yesterdays mail about heat, i am assured that my temps will drop once the arctic cooler cement beds in, currently at 53degs under full load, but am told i can expect to get that under 50 degress as soon as she is bedded in. if not i will reseat it with arctic silver.


anyway, my only minor gripe is i am having to use my 5/6 divider with my ram.

it is the G-skill standard 2gb ddr500 ram from overclockers, and it appears it should be running ok at the standard 1:1 with a 250mhz fsb.

sadly it is very flaky when i do that :/

now if it cant be fixed i am not bothered, this is the fasted computer i have ever used, but if i can get it quicker why not.

my motherboard is a brand new asus a8n-sli premium. it doesnt state the memory dividers (its a bit odd) for 1:1 you select ddr400, 5:6 ddr333 etc.

i selected the 1:1 DDR 400, and wacked the fsb to 250, but under prime it failed within 5 mins, and it couldnt complete a round of 3d mark.

at current speed - (2805) with the 5:6 rati0 the ram is at 425mhz and it seems rock stable.... but it is meant to be ddr500 ram.

i know other things can affect it, motherboard stability at haight fsb's etc but i would have thought that should be ok at these relatively low levels.

It will certainly make the system more stable. 250mhz bus speed x5 puts it quite a way out of spec. x4 takes it back to 1000mhz, which would be right on the money.

sadly no joy..... knocked back to 4 and still froze.

Run at 1T, it is up to 10% faster.

Memory instability can be caused by the mobo, BIOS version, PSU, heat, memoryslots and ........


hi

managed to push my memory times a bit... have given up on ddr500 now, as it isnt happeneing even with more juice.

still with 1T mem timings, as well as pushing the others a bit i am getting 8730 on 3d mark 05 which i think is ok for now :)
