Need help in Overclocking Corsair Dominator PC2 8500/1066

Hi,
I need your advice because I tried today to overclock my new kit DDR2 Corsair Dominator PC8500. My config is as follows, I have a Core 2 Duo 4400 3.1GHz CPU with 2 x 1GB Corsair Dominator PC8500 at 2.2V and (coef * 2.66 then) and Gigabyte 965P-DS3 ver 1.0 with chipset ventilated and updated BIOS. I have a old RAM working on the system. Now I had added the Corsair and want to overclock the same. Need some help for that.

Did you do CTRL + F1 in bios to access the advanced settings. According to a site specializing in overclock the motherboard they were quite disappointed this motherboard. Go to the bios advance settings. I just update my BIOS to the latest version. In many mag, this memory was the reference with the Asus P5B deluxe. All have achieved incredible frequency.

Re: Need help in Overclocking Corsair Dominator PC2 8500/1066

In my case I have a Corsair 1066MHz which is set on 5-5-5-15 at 2.2V, In accordance with the timings and voltage the maximum much be 840Mhz. The fact is that the P965 does not support PC8500 officially takes no argument as well. On my Core 2 Duo 4400, it is also written 2GHz, 3GHz and do not interfere at all. If all were sold THAT PC8500 owners to P35 for example, it would not work. Then adjustment coef memory is weird.

This tends to prove that your motherboard is mismanaging desync up. Have you tried starting from a higher FSB. Otherwise it is also possible that your memory is faulty, it seems to me surprising that it is the motherboard. I tried with a higher FSB, but it crashes above 330MHz. I remind you that this is a C2D 4400, 200Mhz origin. I think my system refuses the FSB which I am trying to achieve.

It is true that it's strange but it may happen that the computer modification dislike certain settings without knowing why. It is hard to understand the relationship between FSB RAM coeff. Sometime this works when you upgrade the bios. I did a test under Memtest. After 2 hours of testing I found that everything is fine on 420Mhz 4-4-4-12 at 2.2V. You can also try to run OCCT to check out the system stability.

Yes MEMtest can help you out to figure out the same. In my case it showed the 350Mhz stop for E4xxx seem consistent. Perhaps the voltage tweak will not be so stable on high coef memory, and my FSB limit forbids me to go higher. That means I need to change the CM and the CPU. A proper upgrades is quiet necessary for the same. So just ensure that you have everything new in that.

It is better to take a kit 2x4 2GB 1GB kit. The increasing frequency of your ram can be in my view will lie to 600MHz for the 8500 24 / 7 is already very well more if you put your ram in coeff 1 / 1 Makes you already 600 fsb. I would say OCZ REAPER PC8500 2 x 2GB with absolutely no heat and take 550Mhz 2.2V. So you can get 8 x 533Mhz see 8.5 x 533 ram is that your sync. You must change Dram frequency and put the DDR2-1066 MHz frequency, only they will not hold if the VDram is Auto, it would also change.
