Hi all! I have a Pentium 3.2GHz with an 800 FSB. My mobo also supports max 800 FSB. Therefor the fastest memory allowed is DDR400(PC3200). A friend of mine wants to sell me his 2 sticks of 1GB "High performance" memory. The problem is that it is PC4000(DDR500?). Could they really work in my system at PC3200 or will it slow down my CPU? He said he had the timings at 3-3-3-8 when he overclocked them to 550. Then they should work at 2-2-2-5-1T at 400. Or am I wrong?
