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.

    Can't change the type from 8166 MHz. to the proper 1866 MHz. but most folks should be able to figure it out...

    Of course, if you have an APU-based system, the faster memory does indeed make a difference... though I agree, it's the exception rather than the norm.
  • JlHADJOE - Thursday, October 25, 2012 - link

    But then its totally contrary to one of the main reasons behind having an APU -- penny pinching.

    These kits cost twice the DDR3-1333 going rate, so that's $75 you could have put into a GPU. Can't speak for everyone, but I'd probably choose an i3 with DDR3-1333 + a 7750 over an A10-5800k with DDR3-2400.

    My thoughts exactly.

    1600 seems to be the sweet spot on price and performance.

    Anandtech did a series of memory frequency tests like a year ago (I forget exactly). While they found that 1333 to 1600 didn't offer much in terms of average FPS gains in gaming, it had a clearer impact on minimum frame rates. I'm not saying it's worth it either way here, but I'd like people to give some attention to minimum frame rates when talking about the benefits of bumps in memory frequency.

    That said, 2400 is obviously overkill here, but that should be obvious to anyone who wants to spend their money efficiently.

    The article the did a year ago (with Sandy Bridge in mind) says absolutely nothing about minimum frame rates vs average... I don't even see how faster memory could have such an effect with a dedicated GPU.

    It might have been techreport. They're the guys who usually do those frame-time measurements.
  • poohbear - Thursday, October 25, 2012 - link

    pseudoking what are u talking about? there is virtually NO effect on minimum frames on a dedicated GPU system. Ever since the memory controller moved to the CPU, the RAM timings have become ALOT a less important component in the system. The only way it shows a difference is when you go to all kinds of outlandish scenerios that involve isolating the GPU and CPU to situations that show some difference between RAM, but in a real world setting those situations are so rare that it becomes pointless to even entertain them.

    But add running virtual machines to your list of reasons why a lot of memory might be good. When working from home I've actually typically got the host machine where I'm doing most of my actual work plus at least two virtual machines running, each VPN'ed into a different remote network. So it isn't too uncommon for me to see about 90% of my 16 gb in use at any one time. And I do occasionally hit times when I have to shut down one VM in order to start another. So I wouldn't actually mind having 32 GB.

    On the other hand, while I need a large quantity of RAM, my 1600 MHz G-Skill works just fine performance wise so I don't need speed - I need quantity.
