Intel D945PSN Memory FAQ

Can I use DDR memory?

No, only DDR2 memory can be used in the Intel D945PSN. DDR2 operates at a lower voltage. DDR2 also uses a different notch than DDR so you can cannot plug it into an incompatible bank.

What does PC2-3200, PC2-4200, and PC2-5300 mean?

The number is the throughput speed of the memory in megabytes per second. The speed you need depends on what the installed CPU supports. You can also run faster rated memory for future upgrading or overclocking.

What does the CL number mean?

Column Address Strobe (CAS) Latency, or CL for short, specifies how many clock cycles the Intel D945PSN motherboard must wait before the memory module is ready to deliver the requested memory. The lower the CL number, the faster the access time.

However, the performance difference between CL=2 and CL=3 is so small that you will not notice any degradation in speed. Unless you are overclocking your Intel D945PSN, you do not need to worry about the CL rating. If you are overclocking, then going with a lower CL may help stabilize your Intel D945PSN motherboard.
