Overclocking P4 630 on a Lanparty 875P-T

[Tlord]

Hey,

DFI lanparty 875P-T
P4 630
GEIL ultra-x pc 3200 (with tccd chips appearantly)


So far it's perfectly stable @ 3,82 on stock voltage. Now when i try to raise the fsb to 270 with memory doing 2,5-4-4-7 @2,9vdimm it freezes up and i have to clear cmos.

Any advise? I really want to get it going at 4ghz

Well, you are using PC3200 ram, which will definately hold back your oc. I am not familiar with the Ultra-X series, so I really don't know how high they will go. Have you tried using the 5:4 divider? Give it a shot, but the 875P-T is known for the dividers not working over ~255fsb. That is when the dividers on my boards start crapping out. And yeah, up the vcore a little bit. Keep it below 1.55 volts or 60C, whichever comes first.

TCCD reaching it limits I 'd say

Try 6-3-3-2.5 or 8-3-3-2.5 at 1/1.

Settings for 5/4, try Cpc addr/control disabled , fine tune -auto, and 1.7-.8Vagp.
I can get 5-2-2-2 5/4 @ 280+ fsb with my 630 with everyhting on auto and just 1.8Vagp but it depends on your memory.If it will not do 5-2-2-2 try 5-3-3-2.
God luck.

Thanks, i'll try that and post the results

Nope, no luck either. I think the memory is the problem here, i tried running the 5/4 divider with your settings ford, but no go. I'll have to find some used gskill or something..
