Corsair Now Retailing 128GB UDIMM DDR4 Kits, Starting at $1755by Ian Cutress on May 15, 2015 8:35 AM EST
Not much exciting happens in the land of DRAM I know – usually the most exciting things occur when we get a standards change, or when capacities increase. Luckily for DRAM manufacturers we got the first taste of consumer grade DDR4 back in 2014, and almost a year later in 2015 we are now seeing capacities double per module from 8GB to 16GB. We reported on one company promoting their 16GB modules, specifically an 8x16GB kit for 128GB, and now it is the turn of Corsair who is guaranteeing US availability as this press release went live direct from the Corsair website.
Corsair is launching three kits as follows:
|Corsair DDR4 128GB Kits|
|Vengeance LPX||8x16GB = 128GB||DDR4-2400||14-16-16-31||1.2 V||$1755|
|Dominatior Platinum||8x16GB = 128GB||DDR4-2400||14-16-16-31||1.2 V||$1980|
|Dominatior Platinum||8x16GB = 128GB||DDR4-2666||15-17-17-35||1.2 V||$2120|
Aside from the price, the timings are naturally quite interesting. JEDEC specifications for DDR4 come in at DDR4-2133 15-15-15, and most of the modules we saw at the release of DDR4 were on those lines, moving up to DDR4-3200 with a slow rise in subtimings. The first two kits from Corsair, the Vengeance LPX and Dominator Platinum, arrive at DDR4-2400 14-16-16, indicating a rise in frequency and a decrease in CAS latency, all while retaining the nominal 1.2 volt specification from JEDEC rather than jumping up to 1.35 volts. Nice.
The other kit in the stack is at DDR4-2666 15-17-17, also at 1.2 volts, which is somewhat in-line with the 8GB module kits we have seen so far. Using our Performance Index rating, as described in our large run-down of DDR4 module performance earlier this year, puts each of the kits as the following:
Vengeance LPX 128GB DDR4-2400 C14 = 2400/14 = 171
Dominator Platinum 128GB DDR4-2400 C14 = 2400/14 = 171
Dominator Platinum 128GB DDR4-2666 C15 = 2666/15 = 177
This is around the Performance Index of the midrange kits for both DDR4 and DDR3, indicating a level of performance in that area.
The pricing on the other hand commands a distinct premium. The Vengeance LPX kit starts at $1755, with the Dominator Platinum 2400 C14 kit moving to $1980. At the top sits the 2666 C15 kit, by virtue of the higher frequency, at $2120. This means per GB:
Vengeance LPX 128GB DDR4-2400 C14 = $1755/128GB = $13.71 per GB
Dominator Platinum 128GB DDR4-2400 C14 = $1980/128GB = $15.47 per GB
Dominator Platinum 128GB DDR4-2666 C15 = $2120/128GB = $16.56 per GB
Compare that to a standard DDR4-2400 8x8GB kit on Newegg retailing at $720, which comes out at $11.25 per GB, or a DDR4-2400 4x8GB kit retailing at $330, giving $10.31, then you are commanding a 30%+ premium in order to get the best unbuffered DRAM density available on X99. Of course, whether you need all that is dependent on your workload.
All kits are available on the Corsair website now, and come with a lifetime warranty.
We have about a dozen DDR4 memory kits in-house that have been sat on my desk for far too long. Keep an eye out for some quick reviews of those in due course.

mjcutri - Friday, May 15, 2015 - linkThe chart has the DDR4-2666 C15 listed at DDR4-2400
mjcutri - Friday, May 15, 2015 - linkAlso, why the big price jump from vengance to dominator with the same specs? Just for the larger heat sink?
Flunk - Friday, May 15, 2015 - linkThe Dominator line has always been about one thing, looks. You want the looks, you pay the price. Quite often the actual RAM is the same and only the heatspreader is different.
chizow - Friday, May 15, 2015 - linkThat's not totally true. The PCBs are bigger and beefier too. How much that translates into actual performance/stability however is debatable. For the typical high-end user it is most likely not worth the premium, but if you are one to overclock everything to the max the extra engineering that goes into Dominator might be worth the premium.
Personally I've always had good experience with Corsair's more mainstream memory lines (XMS3 and now Vengeance) in terms of stability and compatibility. There is a benefit to economies of scale and popularity, as mobo makers will generally go out of their way to ensure Corsair kits' SPDs are supported. I can't say the same for some lesser known brands I've used, currently Adata kits that won't do their rated 2800MHz on my X99 board (most likely a BIOS SPD support issue).
Zak - Sunday, May 17, 2015 - linkThat puzzles me. A gamer/tweaker with a penchant for the looks is unlikely to need 256GB or more of RAM in their rigs. Most enthusiast motherboards don't even support that much. Someone who needs that much RAM is likely not to care much for the looks and just needs lots of work done. We're taking high end workstations and servers here.
slyphnier - Wednesday, May 20, 2015 - linkiirc corsair saying that dominator series using cherry picked chips + manually tested, so its OC better than corsair other series, basically it for OCer otherwise u dont get any value buying dominator series
Laststop311 - Saturday, May 16, 2015 - linkThe dominator platinum also can be connected to the corsair link system monitoring hardware and you can get speed and temp readings of the ram through the link software. Maybe some other things link can do that I am not sure of.
Hrobertgar - Friday, May 15, 2015 - linkIn the table, the second Dominator Platinum kit lists its speed as 2400 instead of 2666 per the calculation in the article.
Ian Cutress - Friday, May 15, 2015 - linkMy bad, should be changed now.
ioconnor - Friday, May 15, 2015 - linkI have 32GBs on my laptop and desktops and it is plenty. Why would you ever need 128GBs?
