Hopefully this should be the end of this thread
Firstly, before I removed the old cards last Sunday I went into the BIOS/CMOS and returned all settings to default, after which the computer would not even boot up in Safe Mode. So I just switched it off and removed them for sending back to Crutial.
Replacement Crutial 'Ballistix' memory cards arrived Saturday morning. The data sheet for these memory cards states
2.8v, so I left the DDR Voltage to 2.8v. All other timing settings back to Default. Changed boot order to boot off CD and ran Memtest86 for about 4 full passes.
NO ERRORS reported :-) Yippee.
Ran Scandisk, deleted and corrected a number of currupted files.
Ran Clean Disc and Defrag (which it said it needed).
Booted up Windows XP Pro and left it running as we've been away this weekend. So far no crashes/faulting modules or any other problems.
Hopefully this will be the end of my problems for the time being, however, I do wonder what was the cause of the memory cards failing as it seemed to a 'creeping' problem that gradually got worse. Have Crutial had a 'batch' problem with these memory cards, or is my computer doing something to 'break' them over a peroid of time. I wouldn't expect Crutial to answer the first part for commercial reasons, however they have replied.
Thanyou to
Crutial for replacing them FOC, especially since I have had the memory for 18 months.
