Pros: Run at specified timings, rank 2
Cons: High heatspreaders and too much rice
These are 2 rank modules, therefore making them perfect for APU guys. Runs at specified XPM and you can set CR to 1 without any problems. Haven't tried optimizing the timings but the kit does 35K read and write and 37K copy on my 4770k with latency of 47.6 ns.
