Bests & Worsts Reviews from Amazon

I have a cyberpower PC, and I bought these sticks to upgrade my current ADATA sticks. Having had problems in upgrading RAM before, I learned that the Clocking Latency is critical, or you will get the blue screen of death, reboots, and eventually you'll burn out your systems internal clocking mechanisms. My current white ADATA sticks installed in my system have a latency of 16-18-18, which is what these red sticks advertise as their CL. However, what was sent has a CL of 16-20-20. I returned the incorrect item with a description of exactly why, and they sent me exactly the same wrong sticks with the same latency of 16-20-20. I am now about to return the same product again for the second time. To all of you experiencing glitches after installation, I would strongly recommend you read the little white tag on your RAM sticks and see if the CL is identical to what you already have. A lot of the 5 star reviews here describe EXACTLY the problems that occur when incompatible RAM is installed. The seller may want to take a hard look at how many of these have gone out not as advertised, because they could be inadvertently wrecking PCs.
