Biostar I915PA7 Memory FAQ

Can I use DDR memory?

No, only DDR2 memory can be used in the Biostar I915PA7. 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 and PC2-4200 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 Biostar I915PA7 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 Biostar I915PA7, you do not need to worry about the CL rating. If you are overclocking, then going with a lower CL may help stabilize your Biostar I915PA7 motherboard.
