Corsair Vengeance Pro Review: 2x8 GB at DDR3-2400 10-12-12 1.65 V
by Ian Cutress on December 13, 2013 2:00 PM ESTIGP Gaming
The activity cited most often for improved memory speeds is IGP gaming, and as shown in both of our tests of Crystalwell (4950HQ in CRB, 4750HQ in Clevo W740SU), Intel’s version of Haswell with the 128MB of L4 cache, having big and fast memory seems to help in almost all scenarios, especially when there is access to more and more compute units. In order to pinpoint where exactly the memory helps, we are reporting both average and minimum frame rates from the benchmarks, using the latest Intel drivers available. All benchmarks are also run at 1360x768 due to monitor limitations (and produces more relevant frame rate numbers).
Bioshock Infinite:
No real average frame rate difference on IGP with Bioshock Infinite - we avoid the 1333 C9/1600 C11 pitfalls. On minimum frame rates however, the inclusion of more memory takes a hit here.
Tomb Raider:
The Corsair kit takes the top spot for Tomb Raider on IGP, both in average and minimum frame rates, despite the overall differences being relatively small.
Sleeping Dogs:
Sleeping Dogs is very consistent - again we avoid the low PI pitfalls at the bottom of the graphs.

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

my buddy's aunt earned 14958 dollar past week. she been working on the laptop and got a 510900 dollar home. All she did was get blessed and put into action the information leaked on this site... http://cpl.pw/OKeIJoteiva - Thursday, January 2, 2014 - link

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).1600 MHz 8-8-8-24 1.5V

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.Senti - Friday, December 13, 2013 - link
"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.
http://www.newegg.com/Product/Product.aspx?Item=N8...
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.
