Hi Steven The DDR2 will fit your PC, but the reason it dose not work is because its 240 pins and yours is 200. To turn on the four core. Type in config in programme search, and click on system configuration, go to boot menu and click on advanced. Window will come up with how many cores you want to run from 1 to 6 press apply, and job done,also there is a PCI lock, if you tick this it will tell the pc to recognise all stuff you plug in vie USB and aux. Also disconnect the remote access, as this gives any one access to your PC The 4core im running is running well temps between 56c and 66c and multitasking is great, all programs running CPU running at 58 percent and Ram running at 40 percent, and instant change from one programme to another. For an intel its very good. Speak to you soon. ill be in the south at the week end. Jack
