ram not stable on stock voltages

[execine]

My ram seems not to be really stable as i cannot run normaly orthos test
at stock speeds, so naturally, i cannot overclock to be my pc stable...

i use kind of cheap one 500w qtek psu and no ups, what should i do next?
immediately buy new psu, o first buy ups, maybe ups would help?

thanks..

btw, what psu would you suggest?

i run core2 duo e6600 with x1800xt 512...

maybe ur motherboard is not stable for overclocking.

oh, i forgot, i have asus p5b deluxe wifi m/b which seems to be a good overclocker...

i don't know what RAM you have, but if you've got 2+ modules, try running them one at a time. i found out with my RAM that 1 module would run fine at stock settings (and above), but the other would be extremely unstable anywhere near stock settings, so I'm going to have to RMA them...

i got corsair TWIN2X1024A-6400 5-5-5-12 xms2

i will try that...

Corsair XMS likes 2.75~2.8V

maybe, but should i increase voltage if ram is working underclocked ?

I do not know about underclocked but at stock settings, XMS wants 2.7~2.8V.
A highly respected member of this board recommends that and I do it.

well, seems like i really had to get a good psu long time ago... i bought today coolermaster igreen power 600w and seems to be stable now at stock speeds i would have never thought about that... always was thinking what's the fu... difference, all of them 500-600w, just ones costing 150$, others 40... why pay more.. stupid me...

I think that is for DDR1, this is DDR2. DDR2 starts at ?1.8V?, so 2.7V sounds way too high. That said, it is common for the highest speed / lowest latency ram to require a little boost in voltage from the stock setting to get the max speed.
