ADATA XPG V2 Review: 2x8 GB at DDR3-2400 C11-13-13 1.65 V
by Ian Cutress on November 11, 2013 1:00 PM ESTSingle dGPU Gaming
For our single discrete GPU testing, rather than the 7970s which normally adorn my test beds (and were being used for other testing), I plumped for one of the HD 6950 cards I have. This ASUS DirectCU II card I purchased pre-flashed to 6970 specifications, giving a little more oomph. Typically discrete GPU options are not often cited as growth areas of memory testing, however we will let the results speak for themselves.
Dirt 3
Bioshock Infinite
Tomb Raider
Sleeping Dogs
Nothing much separates any memory setting when using a single discrete GPU.

The silly part is that this is marketed as "gaming" memory while its advantages in gaming on a discrete GPU are minimal. It should be marketed as accelerating applications, which would be a much more reasonable statement. I bought 2400MHz memory not because I play games but because I perform encoding and file compression on my PC, and that is a situation where fast memory makes a difference.As far as making a recommendation on value, Ian stated (and I agree) that memory prices are very volatile. It's basically impossible to make a lasting value comparison on memory because of this. What is a great deal today could be eclipsed next week by a dramatic price decrease of a faster, better product. I agree with Ian omitting a value comparison because it would be pointless a month after the article is posted. However, the performance comparisons of different memory speeds and timings are still of value.
I think the general conclusion he stated is still of value - buy something faster than DDR3-1600 but don't spend too much money because the performance increase is minimal beyond that.

Are any of your planned reviews going to look at the impact of timing relaxation needed to run 4 dimms instead of 2? Having bumped off 12GB a few times I'm now running 18 in my aging i7-920 box; and with both my browsers (Opera, FF) having multi-process upgrades forthcoming that will let them expand beyond the 4GB barrier I've decided on 4x8gb for my new system.The Von Matrices - Monday, November 11, 2013 - link
I don't understand why you're creating a new term "performance index" instead of just using the more standard time to first word (in ns). It would behave exactly in reverse to your "performance index" with lower times being better but otherwise the comparison would be the same.ShieTar - Tuesday, November 12, 2013 - link
I agree. Its not only more standard, it is also physically more meaningful, and can be adapted to describe the performance of software with known algorithms E.g. if your ramdisk is reading 512-Byte-sectors from memory, its performance will scale with the "time to get a full sector".But of course, frequency is also a much more useful parameter to distinguish electromagnetic signal than wavelength, and you still can't get anybody who learned their field on wavelength to give it up. Once people start to think within certain terms, they are very stubborn about changing definitions.

If you run IGP benchmarks can you please run at something relevant? 11 fps is not relevant.cmdrdredd - Monday, November 11, 2013 - link
Still with these big heatsinks on the memory? I almost have to use the low profile Samsung stuff because of my Noctua cooler not allowing much clearance.meacupla - Monday, November 11, 2013 - link
I think these unnecessarily tall RAM heatsinks are still being made, because the manufacturers think people will use CLC CPU coolers instead of a dual tower heatsink.or maybe they think the only people who will buy this type of RAM are people with real water cooling loops.
or maybe they are for LNG overclocking contests or something.
Either way, if the customer is sensible enough to buy a tower heatsink in the first place, I'm sure they would also be sensible and buy some lower profile, 1600Mhz or 1866Mhz CAS8 or CAS9 RAM, instead of overkill 2400Mhz.

giant ramsinks long predate CLCs. For that matter I'm fairly sure they predate tower style heatsinks as well.Hood6558 - Wednesday, November 13, 2013 - link

Some battlefield 4 tests would've been nice... According to corsair, 2400 memory was giving up to 20% better performance than 1333.mbut I've yet to see another test like that one to corroborate.
