Hello , i just baught Crucial Ballistic DD2 2gigs PC6400 few days ago and i just seen the Crucial Ballistic DDr2 PC1066. are the two that much difference between each other? or did i make a mistake going with the ddr800

Depends on whether your motherboard supports memory at ddr 1066. Also, depending on the rest of your components, you may not see any difference. If your memory is the bottleneck then 1066 may help.

Honestly though, if the ddr800 was quite a bit cheaper than 1066 ($20-30+), then just keep it.

Fast memory, don't worry about it.

well im getting GIgabyte P35 DS3L and it support DDR1066 , but can i OC later on? or is DDR2 800 and DDR2 1066 not that much of a difference.

you'll be fine. You can overclock the memory to 1066.

As you have the top of the line Ballistix memory it should be able to reach quite a lot higher than the specified 800, even more so if you relax the timings a little (I'm assuming it's CAS 3?).

BOTH sets of my Ballistix PC2-6400 can run DDR2-800 at CAS 3 or DDR2-1200 at CAS 5. No mistake there.

In dual-channel mode, you won't get ANY performance benefit from running the memory clock at higher than 1.5x the CPU FSB clock. Gigabyte calls the ration "3.00" where they refer to memory data rate versus CPU FSB clock rate.

So basically, running the memory at Gigabyte's "3.00" setting will put your memory speed at DDR2-800 (400MHz clock) with an FSB-1066 processor (266MHz clock). And since the memory you've chosen overclocks well, you can get to FSB-1600 (400MHz clock) while still keeping the memory at gigabyte's "3.00" setting.

Most of the people here are running 32-bit operating systems where anything more than 3GB total memory doesn't make much sense. Finding a user of a 2x 2GB Ballistix kit could take a while.
