G.Skill Sniper Series 8 GB Dual Channel Memory Module (F3-12800CL9D-8GBSR2)

So I grabbed 2 sets of this up. My rig is current and in my sig, so check the specs. I almost moved to 1366 from my phenom 2 platform for the triple channel memory until I did some more research. Sandy bridge is dual channel memory, but just as good if not improved over triple channel stuff.

My sandra memory bandwidth at stock and 1.25v was around 20 gb/s. I decided to shoot for the 1866 overclock. I needed 1.35v to get stable in prime and also discovered I needed a vccio bump to 1.16v after passing memtest but failing a worker after a couple hours in prime, so be weary of that. Timings for 1866 were loosened to 10-10-10-25 from stock 9-9-9-24 although Im sure that there are some that could be tightened back up on 1.35v Im currently running, or maybe with a little bit more voltage. Under the 1866 overclock my sandra memory bandwidth is about 23 gb/s and my latency is 58ns.

These sticks have great performance for any platform. And on sandy bridge where the cpu/IMC are so closely intertwined, I cant help but imagine such a reduced voltage (and by proxy, temperature) which will encourage chip longevity.
I decide to go with these sticks after being sorely dissapointed by garbage corsair vengeance. Two sets failed on me and would not run at rated speeds no matter the voltage increase, with only 2 dimms populated. Corsair makes good products, just not memory in my oppinion. Stick with gskill for that and you wont be let down.

As you can see from my pics, it is only slightly bested in the bandwidth department by triple channel, but the difference is really negligible.

The following benches are with the 1866 overclock. Its very easy to attain so sorry I didnt include the stock benches as well.



This picture is with highly overclocked ram (2ghz i think- the yellow one) with tighter timings on an AMD platform, at look at the bandwidth improvement of the sniper used on sandy bridge.
