Thread: 4GB-800MHz vs 2GB-1066MHz

    Default 4GB-800MHz vs 2GB-1066MHz

    Which RAM config is best for performance boost (real life benchmark), considering that the CPU & other components remain unchanged? I mean, which is more important for performance: memory capacity or memory clock? The 4GB kit are Kingston Value RAM while the 2GB kit are Kingston HyperX RAM.

    CPU: Intel C2D E8400 3GHz (6MB L2, 1333MHz FSB)
    Mobo: Asus P5K Pro (P35 chipset, support up to 8GB of 1066/800/667MHz memory)

    Memory clock is usefull for benchmarks only: super pi and things like that.
    For everyday use like gaming and other apps, memory capacity is better.-

    My Gigabyte P35-DS3L system is currently running 6GB of memory at 828MHz using 4-4-4-12 primary timings. With 4GB of PC2-8500 ram, memory speed was 1080MHz using 5-5-5-15 timings.

    As mentioned above, benchmark scores are lower at 828MHz, but real world performance and gaming benchmarks are virtually identical.

    Check out DDR2 800 CL5 vs 1000 CL4 vs 1200 CL5, a comparison for some specific benchmarks.

    Well, this is awkward... After installing another 2 sticks of 1GB RAM (now total: 4GB), Windows is unable to detect my sound card. I thought I installed it incorrectly, because I also replaced the hard drive's SATA cable after installing the memory modules. The sound card's rear was too near to the SATA ports, so I temporarily removed it to avoid my hand from bumping into it. But no matter how many times I reinsert the sound card, Windows still cannot detect it. Now I don't think the problem is the sound card because its Power light is on.

    My sound card is X-fi Xtreme Gamer Fatality Pro. It comes with 64MB on-board memory (Creative calls it X-RAM). So... anyone has a problem similar to mine? Can reinstalling 64-bit Windows solve this?
