I have mentioned this before in our recent memory review list, but it is worth mentioning: reviews are often just snapshots in time, and when price is such a major factor with regards to memory, if a kit happens to have a heavy discount at the time, it can impact the review conclusion.  Memory can be a null point in a motherboard: stick in the cheapest 1866 C9/C10 kit you can find, enable XMP and away you go with no afterthought.  More expensive kits do not always equal performance, and as our benchmarks go, higher specification kits might also have little affect (expect BF4 testing, where initial reports say it is relevant and I will add in our 2014 testbed update).

The problem Corsair has with this nice looking Vengeance Pro kit is twofold: at 2400 C10, there are very few gains over a slower 1866 C9 memory kit to be hand in terms of real world benchmarks.  You can throw as many synthetic benchmarks at me as you like, I personally do not care – they do not show any direct real world benefit and are utterly pointless for memory reviews.  The other problem is the price.  Compared to other DDR3-2400 C10 2x8GB 1.65V memory kits:

$150: Team Xtreem LV DDR3-2400 C10 2x8GB 1.65V (on offer)
$175: G.Skill TridentX DDR3-2400 C10 2x8GB 1.65V
$177: Avexir Core ASUS Z87 DDR3-2400 C10 2x8GB 1.65V
$177: Avexir Core MSI Gaming DDR3-2400 C10 2x8GB 1.65V
$177: Avexir Core MSI OC DDR3-2400 C10 2x8GB 1.65V
$230: Corsair Vengeance Pro DDR3-2400 C10 2x8GB 1.65V
$280: Corsair Dominator Platinum DDR3-2400 C10 2x8GB 1.65V

Any reasonable gamer is going to jump on the cheaper memory kit (saving either $80 for the on offer kit or $55 for the next one down) and boost a GPU a grade or spend more on CPU cooling.  While there is some amount of overclocking headroom in our sample, the loose XMP tRFC and tRC timings might be cause for concern as well.  Ultimately Corsair need to price this kit around the $170-$180 mark to be in with a shout of selling volume to users building their own systems.

    What are the exact voltages each timing/subtiming? You only list the subtimings and peak MHz, but no voltages.

    Ian Cutress,
    Hello! This is another article stating 1866/C9 being the minimum for Haswell and to avoid 1600 or less. Even going so far as to say, "Any kit 1600 MHz or less is usually bad news."

    However, this ignores 1600/C8 modules. The 1600/C8 score a 200 on your Performance Index at stock timings. This is at your recommended 200 level. There are several kits of 2x4 GB 1600/C8 on Newegg that have memory profiles of 8-8-8-24 at 1.5v. I'll repeat, these 1600 8-8-8-24 1.5v kits score 200 on the Performance Index and hit the current memory sweet spot for most people of 2x4 GB. This scores within around 3% of the 1866/C9 kits which have a Performance score of 207.

    The reason I bring this up is that the 1600 8-8-8-24 kits are often less expensive than the 1866/C9 kits and offer essentially all of the performance.

    I enjoy reading your articles and appreciate how active you have been lately!

    Here is an example of a great value for a 2x4 GB kit. This item has 500+ positive reviews and normally sells out when it goes on sale (as it is now).

    Where in the article does it state this? These days I want the most compatibility and reliability, and that means being in the JEDEC standard and at 1.5v. I don't care about a few extra fps or synthetic performance figures, I'll save my $80 and enjoy increased stability. Reply

    "we are not going to set any records" with tRFC at 10? lol, sure we would! Do you actually understand the timings you are writing about? Real tRFC is the line above where the numbers are near 300. Now we have huge table of timings that is totally useless because we can't trust it at all...

    Btw, your spam filter is awful – looks like it blocked my (dynamic) IP for unknown reason.

    Oh dear god. Not this again. It is time for a thorough debunking, based on the data presented, because clearly it is not going to stop.

    Established from Anandtech's own testing data:
    There is no distinguishable, patternable difference between 8GB and 16GB memory kits. In some cases, there is a swing one way or the other, but nothing is consistent.
    I think that most enthusiasts would recommend, if asked by a friend on a midrange budget, a 1600 8gb kit. The lowest price for that at C9 timings on newegg is $55. Not the $150 - 250 being bandied about for these moronic kits.


    An 1866 C9 16GB kit comes in at ~$115. (It is safe to assume that *some* kit will always be on offer.)

    So let's look at the conclusive data:

    From all the graphs, we can conclude the difference between the Best "stupid" kit and a reasonable 1600 c9 kit is:

    Average 2.78%
    Max 13.27%
    Min 0.00%

    The best results for the stupid kits are:
    13.27% running Explicit Finite Solver (3d only, the 2d result was 3.3%) on an IGP. Anyone running this is not using an IGP to do it, I suspect.
    12.91% on USB3 copy. The page for those results states they are pulled from the Motherboard reviews, so there's no indication this speed isn't motherboard specific rather than memory specific (as some AsRock boards have USB boost which allegedly seems to work). One result on this same test had a 34.55% lead, but it had the same lead (or larger) on "faster" kits than the 1600 kit, so I am treating this as an outlier.

    The vast majority of the results are just not in the stupid kit's favour.

    The "Weird triple unbalanced" above refers to the idea that there is some lunatic out there running a 4 generation old Dual GPU card in crossfire with a different, single GPU from the same generation but a different spec. This is referred to as "esoteric" but I think it's safe to assume that the only person doing this is someone who has video cards sitting in a pile next to a testbed because they're a video card reviewer.

    Suffice to say I don't think this test is representative of any real world use pattern, but then neither are a lot of the tests where the stupid kits "shine" (if you can call 12% advantage for a 300% price premium "shining").

    The 5970 and 5870 are the same GPU. It might have been interesting to see if downclocking the 5870 to match the 5970 made any difference, but this isn't as odd as you seem to think. I would guess a 3- or 4- card tri- or quad-Crossfire setup would be less common, given that it isn't easy to find motherboards that can take 3 or 4 dual-slot cards.

    It's slightly skewed in that the setup is current-gen other than the video cards, but it is similar to the way quite a few people build. They don't necessarily build a brand-new box every couple years, but replace modularly - I went from an AM3 board with an Athlon64 processor to a PhenomII, to an AM3+ board (which necessitated a RAM upgrade), then replaced the video card twice. My video card is 3 generations old, but handles what I play just fine, so next time around will be another processor upgrade.

    Intel-land is a little different, since they change sockets more frequently and a lot of people didn't see it worth the expense to upgrade when there was socket compatibility (SB -> IB, for example), but this setup doesn't strike me as that unusual. If I dropped the kind of money it takes to get a triple Crossfire setup, I'd hang onto it until the games I played started to overwhelm it.
