TEAMGROUP XTREEM DARK PC2-8500 vs CORSAIR PC8500 4GB XMS2 DOM

What's your cpu? If you're interested in overclocking and don't want a bottleneck, I'd get some DDR2 800 with low timings. If those are your only options, I'd go with Corsair.

thanks for your reply.

I have a q9550 overclocked to 3.6. I was going to go for Corsair but a friend pointed out the Team xtreem memory which is quite a bit cheaper. HAvign never heard of the brand i thought i would ask.
Oh and I have a P5qPro mb

I would still go with some DDR2 800 with low timings. You'll be bottle necking the q9550 unless you lower the frequency on the ram.

Where do you live (can you buy from newegg.com)?

Thanks for your reply!

Thats a problem. I live in Portugal so I can't buy from Newegg. I can however, give you a link with the RAM that I CAN buy.

As you were saying that i shoudl go with 800mhz RAM, I was looking at the Corsair XMS2 Dominator: http://www.mpinfor.com/product_info.php?cPath=29_81_395....

Yes, that's probably your best choice of ram from that site.

Thanks alot for your help!
