Pros: Good price

Cons: 1 of the modules was bad and was causing BSOD errors. Ran Memtest86 on both modules for 12 hours and got 6 errors. Took one of the modules out and ran the test again. This time I saw 10 errors in 12 hours. Swapped modules and it ran clean for 12 hours. Definitely one of the modules is bad. I'll contact Patriot and see how good their lifetime warranty is. Note, I bought this memory 2 months ago but just got around to bulding the PC 2 weeks ago and the memory was bad out of the box. It took me that long to isolate the cause of the BSOD errors.
