Review on 💾 CT51264BA1339 Crucial 4GB DDR3 1333MHz PC3-10600 CL9 UDIMM 240-Pin Unbuffered Desktop Memory Module by Jeff Johnson

I liked the price. Liked the reviews. I ordered an upgrade from 4GB (2x2) to 8GB (2x4). There was some concern about how this RAM would work with my MSI motherboard and the original RAM. According to Crucial, everything is compatible. Easily installed cards in 2 open slots. Booted up and both BIOS and Win7 immediately recognized all 8GB. Win7 immediately showed a loop freeze, and every 30-45 seconds the active Windows panels were deactivated (you had to click them again). Was skeptical it was memory related but before that everything worked fine. Who cares about all the details, but the painstaking trial and error troubleshooting uncovered (I think) a driver problem (the most common culprit in Win problems). Now everything works fine. I'm still not sure how upgrading the RAM will cause problems with the USB wireless driver, but I will say that the problem is on the driver side, not the RAM. If there is anything else to report, I will update the review.
