Negative Positive
Title: Defective DIMM
Review: This product failed as it warmed up to operating tempererature. The warmer it got, the worse it got. It took me some time to figure out it didn't work when warm. I of course tested it immediately after installation using the BIOS memory diagnostics and everything was fine. Then later my system started failing, going to the dreaded blue screen (Windows 7 Pro 64-bit) and automatically rebooting. I knew the only thing I had changed was the new DIMMs so I shutdown and removed and reinstalled, tested again. Of course it had cooled down by then and tested fine. I actually had to restore my hard drive from my server backup. I finally calmed down and thought it through, tested the memory, let it warm up, some problems, warmed up completely, system would not boot all the way without blue screen and restart, tested again using BIOS diagnostics and it failed first test. Removed DIMMs, restored system AGAIN, and everything works fine.
Is the review positive or negative?
