I have a homebuilt system appx. 4 years old, specs are posted below. I'm looking to add another GB of ram. The current ram I have is 2 sticks of Corsair CMX512-3200LL, as they came in the matched set TWINX1024-3200LL. The latency on these sticks are 2-3-2-6 1T. I am having an extremely difficult time finding the same sticks with those timings. I was wondering if i will suffer any significant performance decrease or stability by adding 2 CMX512-3200C2 sticks as seen in the matched kit TWINX1024-3200C2. These have higher latencies of 2-3-3-6 1T. I was also wondering if anyone knows of any place i can get my original RAM for a reasonable price. Another option is to just get 2 sticks of 1GB ram, if the price difference isnt too great. Please let me know what your opinions are.

I would just get 2 gigs of ram. The prices have dropped a lot and you can get 2 gigs for as little as $150.00.

I heard that it is better (more stable) to have two sticks vs four in some systems.

That's because they haven't made exactly those sticks for close to 4 years -- products change within weeks/months in the memory industry.

You should be fine.
