Corsiar Memory OC problem!

[jh616]

I have got the CORSAIR CM2X2048-6400 DDR2 kits
http://www.newegg.com/Product/Product.asp?Item=N82E16820145590

I can run system stable at 4-4-3-4@800mhz (FSB 200) on 1.9v (memory voltage). The problems came when I try to OC. You can find the settings and result on the table below:

FSB RAM Voltage Status
200 800 1.9v stable
230 920 2.3v stable
240 799 1.9v stable
240 960 2.3v no post
250 750 1.9v stable
250 833 2.3v stable
250 1000 2.3v no post
266 888 2.3v not stable
270 540 1.9v stable

It seemed that memory bandwidth can’t exceed 920mhz, even if I set the memory voltage to 2.5v.
Did I buy a bad corsair memory? I have no idea why this happened. Because this memory can OC to 1048mhz according to legitreviews. http://www.legitreviews.com/article/258/1/

I wonder this problem might cause by the MB, for Gigabyte is not good at OC. But I don’t have an extra MB at hand, so I can’t do the test.

Does anyone can give me some help?

Thanks!

not all sticks of ram oc to the same level, even of the same model. have you tried loosening timings any?

Yes. I did loose the timing to 5-5-5-15 when I OC.

could also be a memory controller limitation.. who knows. it's really hard to say without testing the ram in a different rig, or testing ram with known performance levels in your rig..

You sure your processor and chipset aren't holding you back? With the Gigabyte board, I don't know what kind of results you can expect.

There's a reason most memory reviews aren't done on Gigabyte boards, I imagine...
