Hi everyone, Its been a while since i've posted here but I need some help. My friend asked me for some help with his memory his computer has been displaying that he doesn't have enough virtual memory. So I looked his computer specs up and found that his mobo supports PC2700. Now here's the question. On the page it says speed supported PC2700 MB/sec (messages at PC2100). What does this mean? Here is the website:http://h10025.www1.hp.com/ewfrf/wc/...docname=c00038821&lc=en&jumpid=reg_R1002_USEN Any help would be appreciated.
