Pros: This memory so far in the M5a99fx pro R2,0 MB I have had no issues. Works great

Cons: The memory is a little tall, with the EVO 212 CPU cooler installed (push/pull config) memory could not have gone in first mem slot, thankfully the 2nd and fourth slots are used when just 2 slots being used.

Overall Review: Have not been able to really test fully this memory with memtest or other software, had to RMA vid card for the build, the dreaded Black Screen with R9 280X, no extra card to use while waiting for rma.

Pros: Just installed on M57SLI-S4 board with no probs Showing up 5 5 5 18, will check BIOS and adjust re the reviews I have read here.

Cons: None

Overall Review: Ordering another set soon

Pros: Installed uneventfully in a Dell Dimension 4700 Better PC performance by far from the 512mb that was in it.

Cons: None

Overall Review: Would buy again....
