Hi I have a Sempron system and I have a question about memory.. how does having expensive 1GB 4000 memory have better overclocking compared to having just ordinary Kingston 3200 value ram? now I was able to increase my CPU perfomance by 200mhz using value ram Iam currently runing a Sempron 3000+ @2.oghz and 900FSB. If I were to buy more expensive OCZ gold 4000 memory will I get a better over clock? Oh yes since Iam only using Sempron 3000+ (754) claw hammer I only have single channel DIMM. thank-you for any advice!
