Sounds like you may have many settings wrong. PC2700 ram is for 166fsb, the XP3200+ runs at 200 fsb, being your running at 100 fsb right now for 1100mhz, And I bet you have the ram set at spd for 166/333, your running seriously Async, which AMDcpu's do not like at all. Now that 3200+ should run at 166 for 1823 mhz without a problem. It will just be recognized as a XP2500+. But the ram should be set to manual and 1:1 or 100% so the ram and CPU are running at the same speed. But as AMD808 mentioned, you need PC3200 to realize the full potential of that CPU. Ram is backwards compatible, meaning higher numbers can run at slower speeds, but it is not forwards compatable, You can only run a little over the rating. Ram specs are as follows.
