Corsair Launches Vengeance 32 GB Quad-Channel DDR4-4000 SO-DIMM Kit for $595by Anton Shilov on December 16, 2017 12:00 PM EST
Corsair on Wednesday introduced its new quad-channel 32 GB DDR4-4000 SO-DIMM kit designed specifically for ASRock’s X299E-ITX/ac platform and Intel’s latest Core i7/Core i9 processors. The kit hits the psychologically important DDR4-4000 interface speed and enables enthusiasts and system builders to put together higher-performance Mini-ITX builds. Meanwhile, as a rather unique SO-DIMM kit, Corsair's new kit won't come cheap.
The Corsair Vengeance 32 GB quad-channel SO-DIMM DDR4-4000 DRAM kit (CMSX32GX4M4X4000C19) consists of four 8 GB DRAM modules based on pre-binned Samsung’s B-die ICs made using the company’s 20 nm process technology. The modules are designed to operate with CL19 23-23-45 latencies at 1.35 V. The kit is only compatible with the ASRock X299E-ITX/ac motherboard and therefore its XMP 2.0 profiles in SPD are tailored for Intel’s Core i7/Core i9 (Skylake-X) processors.
The new Vengeance SO-DIMM memory kit complements Corsair’s 32 GB quad-channel DDR4-3800/CL18 kit the company launched after ASRock initiated sales of its unique Mini-ITX motherboard based on Intel’s X299 PCH and compatible with the latest enthusiast-class Core i7/Core i9 CPUs in late October. The new DDR4-4000 SO-DIMM kit for the X299 platform can increase memory bandwidth by 5% to 128 GB/s when compared to the DDR4-3800 kit, which is hardly signigicant, but DDR4-4000 is an important milestone in general, if only for bragging rights. Therefore, I wouldn't be surprised to see G.Skill and possibly other suppliers of high-end memory modules to introduce their own DDR4-4000 SO-DIMM kits in the future.

The Corsair Vengeance 32 GB quad-channel SO-DIMM DDR4-4000 memory kit is now available directly from Corsair and from select resellers. Enthusiast seeking for maximum performance out of their Mini-ITX rigs will have to pay $595 in the U.S. and €615 in the E.U. to install the kit into their systems. It is noteworthy that at press time neither Amazon nor Newegg carried the kit.

ScottSoapbox - Saturday, December 16, 2017 - linkI prefer the 64 GB 3200 I got for the same price.
LordanSS - Saturday, December 16, 2017 - linkProbably has better timings as well.
ddrіver - Sunday, December 17, 2017 - linkTimings are irrelevant in most cases, especially when it comes to high end products. They're all pushed to the limit of the memory cell anyway. If you count in nanoseconds it's more or less the same. You increase the frequency so the same operation takes more cycles but the same real time.
But why am I not suprised that AT audience is still at the "chasing numbers" level.
willis936 - Monday, December 18, 2017 - linkBecause the numbers are worth chasing. Specifically baud / cas
jabber - Monday, December 18, 2017 - linkI just make sure if 2T is set I change it to 1T and that's me done. I left all the timing tweaks back in the day of my nForce4 DFI LanParty 939 board.
ddrіver - Monday, December 18, 2017 - link@willis936: "Worth"? Is "within margin of error in some benchmark" your definition of "worthiness"?
CAS 19 is a lot worse than CAS 14, right? Like 25% slower. I'll let you in on a little secret. Those numbers are relative. They mean nothing by themselves. CAS 19 for DDR4 4800 means ~7.9ns. CAS 14 for DDR4 3200 means ~8.8ns. "Better timings" right?
You guys know how to count, I'll give you that. But you sure as hell don't know what those timings mean, or what's better.
ddrіver - Tuesday, December 19, 2017 - linkAnd just as a sidenote, CL19 for DDR4 4000 is about the same as CL15 for DDR4 3200.
The_Assimilator - Thursday, December 21, 2017 - linkWell, duh. That's why you need to calculate the "performance rating", which you get by dividing the maximum bandwidth by the CAS latency.
ddrіver - Thursday, December 21, 2017 - linkLo, no. You just look at the timings and victoriously conclude that the DDR4 3200 CL15 is 25% better than the DDR4 4000 CL19.
When talking about binned products you don't need to calculate much. The chips are already pushed to the highest frequency and lowest equivalent timings, which is basically almost always the limit of the silicon. The point where you can't get better timings without lower frequency, or higher freq without worse timings. Any difference at this level is purely academical.
And you can almost see the wheels slowly turning in the head of the guy who was just saying that "the numbers are worth chasing". Especially CAS, ofc.
These day I feel like I can pop open a bottle of champagne every time I see an intelligent comment around here.
flgt - Thursday, December 21, 2017 - linkDon't you still get a performance bump with higher data rate even if the transaction latency is constant since you pull large blocks of memory into cache?
