COMMENTS:
The Vantec Stealth is the quietest PSU I have ever used. Also, the voltages are consistently above its rating.
PROBLEM SUMMARY:
Starting with the first installation of Windows XP, I began getting random BSOD stop errors, most of which pointed to an "unknown driver problem". The errors included all the usuals, IRQL_NOT_LESS_OR_EQUAL, BAD_POOL_CALLER, PAGE_FAULT_IN_NONPAGED_AREA, MEMORY_MANAGEMENT, NTFS.sys error, some didn't even have a name. Following "numerous" clean installations of Windows XP, as well as replacing the PSU, video card, etc., and several adjustments to BIOS, I finally broke down and RMA'ed the bundled board to my retailer. They ended up replacing both memory modules.
PROBLEM SOLUTION: The original dimms (two Kingston ValueRam KVR400X64C3A/512 modules) were built with "Vitelic" brand chips. In single channel mode they worked great. But for some reason these chips would not work in DDR mode with the ASUS board. The retailer replaced both dimms with two similar Kingston ValueRam KVR400X64C3A/512 modules that were built with "Elpida" brand chips. DDR mode works great and I have not had any problems or crashes since the dimms were replaced.
