other:

Windows was crashing constantly, so I troubleshooted with Memtest and found the problem RAM related.

 

The mobo is known to be picky about 400Mhz RAM, especially if they are bad. However, VS512MB400 has worked before on a PT800CE-A, and it will work this time if I can get a fully working Corsair in it. I am unable to exchange the RAM in store because I have sent out the UPC for a rebate. I have already tested the mobo with several other dual channel RAM sticks and it works without any Memtest errors. I have tried the VS512MB400 in an Intel 875P mobo and it ONLY works UNDERCLOCKED at 333mhz.

 

This RAM does not work at its specifications, so can I RMA :(:. I don't need to overclock, I just need it stable and working. Soon. Thanks, RAM guy.

Getting errors with both modules would suggest some other problem, I would try and set the Dim Voltage to 2.7X Volts and test them one at a time. And if you still get errors, then lets try replacing them. Please follow the link in my signature “I think I have a bad part!” and we will be happy to replace them or it!
