The G.Skill DDR 1333 7-7-7-21 1.5v,it will run at 1600mhz at 8-8-8-24 1.5v,It will even run at 1866Mhz at 10-10-10-30 1.5v.This is pretty good memory to be so cheap.I have alway ran it at 1200mhz anyway since 1600mhz did'nt really show no gain,Plus my CPU run a little cooler at 1.5v instead of 1.64v that my OCZ had to run at.It does load my desktop quicker ,I have ran any benchmarks ,but I doubt there will be any difference .I hope it makes decoding faster.
My motherboard only has four DIMM slots. I believe what it does is a bit of a hybrid implementation. It'll run three sticks in tri-channel, and one in single. So that way you'll see a performance boost due to the tri-channel, but can still enjoy greater amounts of memory.
Not 100% certain on this my self, but I've got all four DIMM slots populated, all 16GB shows up correctly, but every where I look it is reported as running in Tri-channel. Can't say I've seen any real performance benefit from dual channel so maybe it is being reported wrong. Don't know.
Anyhow I've always valued quantity over dual vs tri-channel.
