ADATA XPG V2 Review: 2x8 GB at DDR3-2400 C11-13-13 1.65 V

Our final set of GPU tests are a little more on the esoteric side, using a tri-GPU setup with a HD5970 (dual GPU) and a HD5870 in tandem. While these cards are not necessarily the newest, they do provide some interesting results – particularly when we have memory accesses being diverted to multiple GPUs (or even to multiple GPUs on the same PCB). The 5970 GPUs are clocked at 800/1000, with the 5870 at 1000/1250.
Dirt 3
Bioshock Infinite
Tomb Raider
Sleeping Dogs
There are obvious games that benefit from high speed memory in multi-GPU configurations: Dirt 3, both in average and minimum FPS data is a prime example. Others, like Tomb Raider, offer a sub-1% difference. Sleeping Dogs seems to hit its asymptotic peak around 2133 C10.

BF4 will hopefully be part of my 2014 test bed, I'm still getting equipment arranged to make it relevant and trying to decide a consistent benchmark. Running through an empty server atm is the only consistent way, but it might not be considered a true representation of what's possible.d9ssk02md - Tuesday, November 12, 2013 - link
Well, on my sandy bridge it only took a year or two of running memory at 1.65V to develop random freezes. Lowering the voltage (and the speed) to 1.5V made the issue completely disappear.Gen-An - Tuesday, November 12, 2013 - link
A bit surprising these couldn't go higher, considering they are likely using Hynix H5TQ4G83MFR ICs. I have some sticks of the same bin (2400C11 2x8GB) but a different brand (Silicon Power) and I've been able to push them to 2933.
