What brand/quality of RAM is this, what mainboard, and what slots are you putting the RAM in? Also, you said you tried different power supplies, but what brand/power level have you tried? [/B]
Memory: 3 Micron PC2100 DDR 266 512MB ECC Unregistered; also I have 3 other sticks of Micron PC2100 DDR 266 256MB ECC Unregistered. Memory was put in all three slots for testing. I run the 512MB in slot 3 on the board
Motherboard: ASUS A7V266 (with latest BIOS). Today I am headed to my old workplace to "borrow" an ASUS A7V266 and an Asus A7V8X VIA 8235 KT400 (266/333/400)MHz DDR ATX for testing.
Power Supply: tested 2 Enermax 350W "AMD/Intel approved".
Right now after running the memory through several testing routines I have not had any failures. Also there have been no reboot cycles since I updated from WinME to WinXP Pro. If nothing good happens with this test session I might just go swap stuff for the following upgrade:
Asus P4B533-V P4 400M/533Hz FSB 845G chipset (DDR) ATA133,ATX
Intel P4 2.26 GHz 512 k PGA 478pin 533FSB Retail Box
Memory PC3200 184PIN 256MB DDR400 SDRAM
Sound Cards Sound Blaster Audigy X Gamer w/1394 Port
If I swap it out with what I have still under warranty I can get this above for $150.
Here is a little blurb about memory problems within WinME from
Extremetech.com .
"According to the report, Microsoft support has confirmed that the problem exists and that they are currently researching a solution. The memory leak occurs when users open large programs or files in Windows ME and then later close them. By design Windows is supposed to "recover" the amount of free memory available to the system for other tasks. However, due to this leak, Windows ME never actually manages its free memory properly, thereby leaving a system unstable and highly vulnerable to freezes, crashes and "blue screens of death." The problem does not affect any other version of the operating system."
I never had a huge problem with ME until having to reinstall it this past time. I never really liked WinME because it was a huge drag but getting it for free was not something I could turn down. If I would not have gotten my copy of WinXP Pro from Microsoft by going to one of their Technet briefings I would not have bought it either.
