Second I am fixing my Brother's Computer. Here is what I got confused. Here how it started. He said his MB died; he will ship me the computer and I can replaced the MB and save his Data AKA Porn :lol: . I said ok no Bigge. I bough the MB for TIME saving. So got him an Asus P4P800-VM MB Upon my diagnostic I found out; his ECS MB is GOOD :w00t:; His retail P4 prescott 3.2 is BAD I crossed check with known Good CPU. Any rate it getting replaced. He have 2 OCZ PC3200 512 a Modules. Running in a Dual Mode. Mean while I installed my spare CPU which is P4 2.6 Gig 800FSB. After installing every thing like OS and Benchmark programs; I have notice some thing real odd 3D mark see FSB as a 200MHZ FSB Asus WebSite where they compare the MB its says it only supports 533/400 When you pull MB specification it says it can support 800/533/400. I though may be 3D mark is goofy so I ran program on my computer. Its says I am running 800 FSB My Dell have 875Chipset; with PC3200 Memory/ P4 with 800FSB. So guys I am so confused now. It making no sense. I use think in P4 with 800FSB memory bus is quad-pumped. The real frequencies are 100/133/200 MHz; in actual data pahses.
