Dominator GT 1866 Overclocked to 2000MHz with BD.

post #1 of 9
Thread Starter 
I dont know if this is a large overclock with this ram but it is the most overclock that I have been able to do with ram.
The timings are the same at both 1866 and 2000Mhz. Is this normal? Can this ram run even higher? Is this too much for this ram?

It is very stable at 2000Mhz. Should I try higher clock?

Is it safe to take memory speed higher than 2000Mhz when its only rated for 1866MHz?

Please let me know if this is too much of a strain on my ram. I dont want to ruin my ram. It seems to be doing fine and they are staying cool. Not reaching over 40C but I am a little concerned seeing that I have not done much memory overclocking and this is the highest I have ever taken speed above the stick's rated speed.

Is it too much for the dominator gt 1866 to handle speeds of 2000 and above?

You will not hurt RAM by overclocking it unless you increase the RAM voltage beyond that specified by the RAM maker.

How fast the RAM will run depends on the CPU it is paired with. AMD Phenom II Denab CPUs will generally run RAM at 1600-1800 MHz. Thurban CPUs will generally run RAM at 1800-2000 MHz. FX/Zambezi CPUs will run RAM as high as 2400 MHz. though unfortunately none of these OC frequencies produce much system performance gain, typical only ~1%.

Thank you for the info. +1 rep
Do you think my ram will support 2400Mhz cause its only rated for 1866Mhz?
Also, I have voltage knocked up 1.525v which is 0.025v over factory specs, is this bad?

I dont think it would have posted without voltage increase from what I remember but I could be wrong. I have seen others increase ram voltage when overclocking. I just assumed that it would help with stability. Is this wrong.

Please help.

There is no way to know how fast your RAM will run stable other than trying it step by step to see. It's OK to run the voltage a little higher - as needed for stablity. Most std. DDR3 RAM is safe up to 1.65v without issue. You can always e-mail the RAM vendor's Tech to be sure.

Well I know there is RAM rated at 1.5v and at 1.65v. Are you saying that RAM rated at 1.5v is safe all the way up to 1.65v?

I do not fully understand your last statement here. Some DDR3 RAM is rated at 1.65v

Yes you safe up to 1.65v according to manufacturer. But i would say 1.7v safe.

Yes most all 1.5v rated RAM is safe up to 1.65v.
