i checked corsairs website, on a troubleshooting page it said this.

Many systems will indeed support DDR 400 memory. However, if for example your system came with a 533 FSB CPU you may be limited to DDR333 memory until you upgrade your CPU to an 800 Front Side Bus (FSB) CPU provided your system will support a faster CPU. The following guidelines may help with this: If the FSB of your CPU is 400 For Intel and 100 MHz for AMD, the memory speed supports only DDR 266. If the FSB of your CPU is 533 For Intel and 133/166 MHz for AMD, the memory speed supports DDR 266/333 If the FSB of your CPU is 800 MHz for Intel and 200 MHz for AMD, the memory speed supports DDR 333/400

this might be the problem but it says on the page where i bought it " This memory has been veriﬁed to operate at 200 MHz (DDR400) at aggressive latencies of 2-3-3-6. "

could this be the problem ?
