Market Positioning

As mentioned in the previous page, this memory kit has some immediate challengers in and around the price range for the capacity:

$145: Corsair Vengence 4x4GB DDR3-1600 7-8-8 (8.75ns / 13.125ns)
$150: Kingston HyperX 4x4GB DDR3-2400 11-13-13 (9.17ns / 12.08ns)
$150: Corsair Vengeance 4x4GB DDR3-2400 10-12-12 (8.33ns / 11.25 ns)
$150: Mushkin Redline 4x4GB DDR3-2400 10-12-12 (8.33ns / 11.25 ns)
$150: G.Skill Trident 4x4GB DDR3-2400 10-12-12 (8.33ns / 11.25 ns)

$145: G.Skill TridentX 2x8 GB DDR3-2133 9-11-11 (8.43ns / 11.72ns)
$150: Crucial Ballistix 2x8 GB DDR3-1866 9-9-9 (9.65ns / 13.40ns)
$150: GeIL Evo Veloce 2x8 GB DDR3-2400 11-12-12 (9.17ns / 12.08ns)
$150: Kingston HyperX 2x8 GB DDR3-1866 9-10-9 (9.65ns / 13.40ns)
$155: G.Skill TridentX 2x8 GB DDR3-2400 10-11-11 (8.33ns / 11.25 ns)

The $145 and $155 2x8 GB kits from G.Skill really shoot across the bow of the GeIL ship Evo Veloce in the same capacities, but most of the 4x4 GB $150 DDR3-2400 C10 kits also offer better XMP sub-timings for the same price, meaning the advantage of the Evo Veloce is obviously memory density per module.

ASUS MemTweakIt

With our overview of the ASUS Republic of Gamers range of products, one piece of software caught my eye while I was testing.  The ASUS MemTweakIt allows for almost complete control of the memory subtimings while in the OS, such that users can optimize their settings for memory reads, memory writes, or for pushing the boundaries.  The upshot of this software in our context is that it takes all the sub-timings and settings and condenses them into a score.  As the memory kits we test contain XMP profiles, these profiles determine a large majority of the sub-timings on the kit and how aggressive a memory manufacturer is.  We should see this represented in our MemTweakIt score.

As we do not know the formula by which ASUS calculates this value, it has to be taken with a pinch of salt.  It could be weighted in favor of one of the settings versus the other.  Normally I would not put such an non-descript benchmark as part of our testing suite, but the MemTweakIt software does give us one descriptor – it gives us a theoretical rate of improvement across the range of kits we test, and allows us to order them in the way they should perform.  With this being said, the results for our kits are as follows:

ASUS MemTweakIt

Percentage Increase Over DDR3-1333

In terms of MemTweakIt scores, the Geil 2400 C11 kit pulls in just behind the G.Skill 2133 C9 kit.  The price between these two kits is $150 for the GeIL and $130 for the G.Skill, meaning if the benchmarks pan out like the MemTweakIt scores, the extra $20 on the GeIL kit is the ‘module differentiation’ between having a 4x4GB kit and a 2x8GB kit.

    Actually, yes you can tell the difference depending on the applications you run. In fact, the distributed OpenCL GPU computing projects I use over at BOINC, the biological research, requires extreme frequencies. The higher the processor frequency, the higher your GPU load and ability to install more GPUs for the project becomes. If I run my RAM at 1333Mhz with my 7950, I need to run 8 work units in order to get that memory to get 80% efficiency. After overclocking my RAM to 1800Mhz I was able to get the efficiency up to 95%. With faster memory, I could run less work units, and install a second graphics cards, although I would likely need 2133Mhz quad channel memory in order to saturate two 7950s in the HCC project. In POEM, I would actually need 4266Mhz quad channel DDR3 in order to saturate a single 7950 more than likely.

    Another scenario is AMD APUs, where FPS almost scales linearly based on RAM frequency because it uses system RAM as VRAM. GPUs are very memory intense, which is why GPUs have 256-384 bit memory interfaces. With an APU, the GPU on the die is restricted to the lame 64 bit memory interface we have with our system RAM.

    RAM kits like these are sold to people who need them, if you don't need them, buy the lower frequency RAM.

    "The higher the processor frequency" I meant "The higher the memory frequency"

    "to get that memory to 80%" should be "to get GPU utilization to 80%"

    What's with the cost analysis of all these high speed $150 kits? Would you actually shell out that amount of money for a run of the mill gaming/enthusiast system when there's a ton of 1600 4x4GB or even 2x8GB kits on Newegg selling for $75-85?

    I've wishlisted like half a dozen G.Skill kits within that range AND with blue spreaders specifically... If I width the search there's tons more obviously, just hoping one of those goes on sale during Thanksgiving for like $50-60, even tho I'm in no dire need to upgrade from 8GB.

    (and yeah, looking at blue purely for aesthetic reasons obviously!)

    I would because it would cut my research rate in half. I run OpenCL GPU projects on my systems, where if I had 2400Mhz memory I could output twice as many work units with my graphics cards per day in Help Conquer Cancer.

    Green PCB? Really? Yuk

    Black or Nothing

    Do you ever look at your ram once you install it?
  • JonnyDough - Friday, October 26, 2012 - link

    That's how I feel. I used to care about the color of my computer case, etc but I realized that its more about longevity and ease of installation for me. It's nice to go with a color theme, but the extra cost each time I upgrade just isn't worth it. So now that I've matured a bit I've decided on mostly black boxes and hardware as its plentiful and price competitive.

    how about adding a folding on cpu benchmark?
  • valnar - Friday, October 26, 2012 - link

    Memory companies will continue to put out insanely spec'ed pieces so they get reviewed by Hardware sites, because it's the only way to get their name out there. Otherwise, memory as a whole is a pretty boring component. Why else do they also need to have interesting names and brightly colored heatsinks? Marketing at its best (or is it worst?)
