Pros: I bought these based on the timings, capacity, price, color and reviews. I installed them as default with no BIOS tweaking and they came up with correct timing on a RIPJAW MOBO. However they were subject to BSOD randomly. Through several weeks of research and testing I found a simple fix of adjusting the default voltage of 1.50 to 1.55 was all that was needed. 1.5 volt was not enough to run 4 sticks of ram (Ok with two but not four). I am now VERY PLEASED with this ram and have not had any more problems in the last 6 months.

Cons: Be nice to have a comment on the package to increase the voltage on 4 stick kits although it may be a motherboard issue not memory.
