Memory Problems...

[Dr_BenD_over]

Workstation this time around. Some rather critical files are getting bad bytes written to them when I create them. Where I should be getting 0x00, I wind up getting 0x10. I've had the program which generates the file checked on both 32bit and 64bit versions of Win7 and the file get's created correctly. If I create the file on my Win7 64b I get the wrong byte. If I create the file in XP Pro 32bit on the same system, the file is OK so I'm thinking it's a problem with the memory above the 3.2GB boundry which it doesn't seem that memtest checks (tested with that and the POS one that's built into Win7) Can anybody recommend something that can do an exhaustive test on all 4GB of ram?

My only thought would be to put one stick in at a time and test.
That way you can be sure that you don't miss a section of the RAM.

Again, I've chased memory ghosts before so everything is subjective. Mind you the Window's 7 Diagnostic is actually pretty damn good a spotting issues.

Good idea, why didn't I think of that.

It's also be routinely having to run consistancy tests on the primary OS drive, WD's tools say there's nothing wrong with the drive

if you get the same error weird, may or may not be ram.

try getting ubcd, and run it from dos, well at boot. grab it here : Ultimate Boot CD - Download the UBCD

Any critical system at work is on a UPS.
