overclock stable, tweak time? :P

[AMG]

HI

I have a
E0 Q9550 overclocked to 3.8Ghz and stable, I have the RAM at 900Mhz (1:1) as I m a noob for memory overclocking, I m wanting to overclock the memoery to get the most out of the system, but I have no idea how to keep the stablity, I m upgrading my OS to 64bit vista soon than try the RC but thats another story

my mobo is a asus tek rampage formular X48 with the 0701 BIOS, there is a switch on my mobo near the PCIe slots what does it do as a side note.


however I feel my voltage are on the high side, but the system itself seems happy when it comes to voltage/temps as nothing is that hot in my HAF case

but I want to lower them
CPU 1.25volts
CPLL @1.6 (mobo keeps overvolting and runiing over that through )
FSB term 1.4volts
SB1.5-1.55volts
SB 1.1 is 1.125
NB is 1.35volts
Dram is 2.2volts nothing fancy
GTL ref voltage multiplers set on North bridge and cpu these are 0.68x

can I inprove these ? i have enabled the Vdrop feature so voltage is a bit more constant.

I see no point in doing like 24 hours stress tests as if its going to fail it would in the first 5 minutes particauly prime however I did run it for over a hour. max temps is 70c fore core #0 than it cooled right off again other wise it sits no higher than 65-66c while priming

regards

Load line calibration does some scary things with ringing when the voltages change, which rather puts me off using it.
2.2V is a lot for DDR2, what's the ram rated to? I'm reasonably sure a set of ocz I had expired because I put 2.2V through it for a while. Will it really not run 900MHz at lower voltage?

You either get to raise the multiplier on the ram, which is likely to push it far too fast to be stable. Lowering timings to 6-6-6 may stabalise it, and high fsb with loose timings is probably quicker. Otherwise, lower the voltage a bit, and test for timings like 5-5-5-15 and 4-5-5-15, see how low they'll go

Sadly that's not true. 5 mins prime stable is nothing, an hour stable isn't that great either. There's good reason why people run it for hours, having it crash 4 hours in is annoying as hell but still shows that your machine isn't stable

OCZ rate the reapers at 2.2 volts for 1066Mhz, high I know but hay i pulled it back on purpose so I can only work on the cpu without RAM being too much problem

i had to enable loadline or i would have needed higher voltage than my titan would struggle so i enabled it and took the volts right off it seems to work fine

as for the stress testing, the person who said that 24 hours inst needed, needs a kick LOL
