I brought a used corsair pc4000 (2x256) a month ago and I never did any test on it. Last night, I was using it on my 3.2E. It pass the MemTest for 8hrs running at default speed(200:200, 1:1). Since the memory is rated at 250mhz, it there a way to test it at 250mhz.

I oc'd my 3.2E to 225fsb and set the mem at 400 which is 1:1 for Asus MB. It passed 13 times and I stopped it. I increased the fsb to 240 and I got tons of errors. Does this mean I got bad chips since it didn't pass 240?

When you increase the fsb, do you need to increase the vcore. I don't think I can boot 3.2E at 240fsb.

Here's my setup:
P4P800
7000A CU
Silenx 400W PSU
9800PRO->XT
Corsair pc4000 2x256

btw, the USB Legacy was disabled.

Unless you can eliminate your CPU by lowering your mutiplier, you will probably need to increase vcore. Don't forget vdimm and chipset voltages also. You may need to look at your timings, for a jump like that.

So basically, I will need to up vcore and vdimm when I test the memory at a certain fsb. right?

Indeed..... you'll have to overclock your system to test the memory at it's rated speed.
