Stability on 939

[wschuerm]

System:

A64 3500+ (DH7-CG 130nm)
Corsair PC4000 rev. 3 (run it at 3-4-4-10-2T)
MSI K8N NEO2 Platinum bios 1.3
Point of View 6800GT 256mb
Themaltake Butterfly 480W PSU
NEC 3500 DVD+-RW
Plextor Plexwriter premium
Maxtor 120 gb SATA
the MSI Wireless module that comes with the mobo
2 * 120mm fan for the watercooling that draw power from the mobo and 4 * 80mm fans that draw power from the powerlines + 1 Coolermaster cold cathode light (tube)
Innovatek XX-flow on the cpu
Innovatek Graph-o-matic on the GPU and OCZ copper ramsinks on video mem
Black ice extreme II radiator
Hydor L30 pump and small watertank
All in a aluminum Xaser III

The reason I give full deatails is because I'm not really sure what my problem is. It might be that the PSU is just not up for the job. But I think it's my own A64 overclocking ignorance.

Most of the errors I get are memory references or just plain old reboots of the system. I ran memtest at memorys rated speed and settings (3-4-4-10-2T (10 is rated 8 by corsair) at 2.75v with 10*250fsb) In memtest v3 i got 9 errors up to 100%.

I don't really know what the problem is, I'm pretty sure my cpu can do 2.5ghz (not sure above that caus the thing really needs voltage currently at 1.65v)

So is it the mem or the PSU.

One other thing that makes me think PSU is that when I overclocked my 6800GT to 400mhz from 350mhz I actually got lower scores in 3dmark03 which is probably the nVidia clock throtteling due to data inconsistency, so maybe the card isn't getting enough power?

If anyone has any ideas, or a good list of steps to follow on a system similar to mine for overclocking then please post.

Try bumping up the voltage first to the CPU. I think those 939s can handle a good bit. I that doesn't work try backing down the multiplyer. Raise the voltage to your agp if you can.
Don't go craisy with the voltages. Just give each thing enough to work. Try more voltage on the ram if you can. I think thats the default voltage on that memory correct?

2.75v is default for the memory to run at 250mhz yes. I've had the cpu up to 1.7 and some more but I don't know what level is to much (I'd like to use my cpu for at least 2 more months).

I think (for now it's the ram in conjunction with the PSU). AFter reading the anandtech review on tccd memory again they said they were using ocz powerstrem psu's for testing now because these yielded higher memory overclocks. I'll probably buy another psu first and then some ocz pc3200 rev2 or some gskill pc 4800 (or at the same time). My watercooling setup should be fine, all components are handpicked and it's not "a kit" It got my PIV down to 30C but I should check if the waterblock is seated correctly on the cpu. On the other hand the thermal monitoring chips on this mobo suck like nothing else. Right now I'm running at 10*240 and 1.6V vcore MSIcorecenter tells me the cpu is 40C PCwizard2004 tells me it's 36C. You pick one....
