Cons: Ordered the 16 GB kit (2 x 8 GB). At first, my PC indicated the full amount of RAM was installed, but only half of it was usable. Did some trouble shooting, and found that with one of the sticks installed, the computer booted. With the other, it would not, no matter which RAM slot it was in. Returned the kit and received a replacement no problem. The new kit is DOA. Neither stick registers. Very disappointing!

Overall Review: I have no trust in Crucial memory now. Maybe it's bad luck, but...maybe not.
