I'm going to buy new memory tommorow and wanted to know what would be better. The memories will be installed on striker ii formula mb and q9550 cpu. also I will overclock my cpu to 3.8ghz .
2x2GB Mushkin XP Black Essential Edition Dual Channel or
2x2GB Mushkin XP Yellow Frostbyte RadioActive Edition Series Dual Channel or
2x2GB Corsair XMS2 TwinX CL5 Dual Channel or
2x2GB Kingston HyperX CL5 Dual Channel
All the DDR2 RAMs you listed are almost equal in performance. Just choose one of those which don't need EPP to be enabled to function in the highest clock (e.g. 1066MHz) and go for the cheapest one from the list. I am a sufferer of buying 2x2GB RAM which need EPP to be enabled for functioning@1066MHz.
Thank you very much for your replies!
I've got corsair memory and very satisfied with its performance. Within less than half an hour i succesffully set them to 1100mhz and cpu @3.9ghz. The system was stable for 7 hours and then i needed to go to work. I want to play more with advanced timings- now they are all on auto and will stress test the system at weekend for 15-17 hours to be sure everything ok.
