im also trying 3 3 3 5 and 2.5 3 3 5..hope all goes well..
forget the "5" part of the timing, 5 does nothing but cause an unstable system. It actually should the the total sum of the first 3 timings...3+3+3=9 Try 8, 9, 10, or 11

i can say tho..ddr501 looks nice...thinkng that in a few weeks i may actually buy some, or make a trade somewhere..
yeah and that DDR500 prolly has some slow dog a$$ timings that your PC 3200 can do...you have top notch ram so save your money.....
