Corsair DDR2 800MHz Gaming memory Maximum overclock

WingZero30 · 22 Jun 2010 at 17:58

Hi guys, I have Corsair DDR2 Ram 800MHz of 3Gb (3X1GB sticks). Currently I am running my ram @ 427MHz(DDR2-854MHz) on VDimm 1.8V (stock voltage); So it is mildly overclocked. I would like to know the maximum overclock people have achieved with this ram and what is the maximum acceptable VDimm? Also how high can I go with this ram on stock voltage? Thanks!

My mobo is Gigabyte EP45 UD3LR.

I'm sorry, I can't answer your question. But may I ask - is your ram running in Dual channel mode (should be able to check using CPU-Z)?

Looking at the motherboard manual, there doesn't seem to be a way to populate 3 slots and maintain dual channel mode.

As I have 3Gb of Ram (3X1Gb sticks); it is running in 'flex memory mode'. So 2 sticks of 1Gb each are running in Dual channel mode while the remaining 1Gb memory stick is running Single channel mode.
In CPU-Z it says 'Channels : Dual & Dc Mode: symmetric'

Ah, fair enough. Good luck with the RAM overclocking

Maybe andi you can give me some advice with regards to your Ram overclocking experience if you did some overclocking of your ram.

I have done a little (got my 800MHz Corsair 2x2GB kit to 900MHz), nothing massively impressive - just slackened off the timings a bit and pushed in a touch more voltage to get it stable. As all RAM is different I would suggest doing something like this in small stages and see how far you can push it while keeping it stable.

My current RAM is actually 1333MHz DDR3, but I have been running it at 1440MHz for over a year with stock volts (1.64v). I'm convinced it is some 1600MHz RAM that was improperly labelled

Thanks for the info :cool:

. Which software program is good for ram testing and also how does ram testing work? I understand cpu and gpu overclock testing but I haven't got a clue about ram testing.

I have seen DDR2 667 modules running @ 975Mhz in bios max OC before temp is an issue and causes instability.

Just dont try and OC the ram too much to be on the safe side
