Summary: Not sure whether those saying 'great' and all knows about the cas latency. At 400mhz, the cl is 18.104.22.168. Only at 333mhz the cl is 22.214.171.124. This made my corsair xms2 400mhz 126.96.36.199 downgrades to 333mhz settings. At worst of all my bios is lock for ram settings!.
PNY memory sticks and known Quality issues - Dont Buy
12 July 2014
Summary: Junk - do no buy. I continue to have failed memory dump error and blue screen of death. I bought these to double my memory running Win 7 32 bit. When using my old Kingston 2MB (1MB x2) modules, I never get these types of errors. The memory type is correct, it is just the quality. After many failures, I researched this on the internet (newegg, etc.) and found that others are having quality issues with PNY memory. I would go with another compnay.

Summary: Ordered total of 4 (2 orders) and received not what was printed on page. Both were corsair and one was ddr2 and other was ddr3. DDR3 not compatible with motherboard and neither was the ddr2 sticks. Started RMA with amazon and sent all back for refund. Email returned states only 1 of the 2 were returned and only a partial refund.
Summary: Received it today. It is PNY Ram, but it is not the same OPTIMA as on the website depicted. It is a plain white packaging with the RAM loose inside of it. Not the product I expected from a professional Product like PNY. Wont be buying PNY in the future. Will most likeley return this and go with Kingston...
