Experience the True Power of DDR4 RAM

It was 2007 that the DDR3 standard was announced and in the years since then technology has only been pushed further. Eventually the memory standard was pushed to the edge of DDR3 limits, until DDR4 smashed through those limits! Corsair DDR4 doubled the bandwidth and dramatically increase clock speeds, whilst consuming less power than ever before.


Motherboard Socket DDR4 Optimization

Pin Out: 288

Vengeance LPX DDR4 form factor is optimized and compatibility-tested for the latest X99 and Intel 100 series motherboards, forging reliably fast performance. With any standard DDR4 DIMM memory socketed motherboard you shouldn’t have any trouble installing the powerful Vengeance LPX RAM and getting that DDR4 performance into your system.


Corsair DDR4 Memory Size

The clever and stylish, low-profile design of DDR4 LPX memory means it can fit comfortably into much smaller spaces. The LPX series of Vengeance DRAM was prepared for when the first of the Micro ATX and Mini-ITX motherboards for DDR4 memory released. In any system that has minimal internal space the small form factor of the LPX DDR4 RAM from Corsair is ideal.


Unlock the Potential within DDR4

Corsair’s Vengeance LPX DDR4 has been built around high-performance overclocking. Each module from the LPX series utilizes highly-screened memory ICs and an eight-layer PCB, with further overclocking improvments through the efficient heat spreader that provides effective cooling. The eight-layer PCB system on these DDR4 memory sticks helps if your computer is trying to squeeze too much information into one layer, causing a significant rise in temperature which can create a multitude of issues.


Cooler Memory for Better Performance

The heat spreader on Corsair LPX DDR4 memory is made of pure aluminum, creating a faster heat dissipation and a cooler operation. Usually the overclocking overhead is limited by the operating temperature, but not for the Vengeance LPX. Due to the unique design of the heat spreader, the temperature is constantly lowered as heat is pulled away from the ICs and into your system’s cooling path. Not only does the heat spreader allow Vengeance LPX to perform better, but the aggressive yet refined form factor looks great in any system.


Utilize XMP for Overclocking in Seconds

XMP 2.0 is supported by Vengeance LPX DRAM along with Intel 100 and X99 motherboards. Simply select XMP mode in the BIOS and it will automatically adjust to the fastest safe speed for the Corsair DDR4 Vengeance LPX. You’ll get amazing, reliable performance without lockups or other strange behavior. Enjoy trouble-free, automatic overclocking in seconds with the support of XMP 2.0.

16GB (2x8GB) Corsair DDR4 Vengeance LPX Black, PC4-21300 (2666), Non-ECC Unbuffered, CAS 16-18-18-35, XMP 2.0, 1.2V is rated 4.7 out of 5 by 13.
Rated 5 out of 5 by from Easy to upgrade ... After initially finding out I would have to unscrew a few things ... Cooling fan at the top of the case ... and move a few cables out of the way ... I managed without much fuss, to upgrade and install 32GB (4x8GB) of RAM into my SCAN 3XS gaming rig - no harm done and the PC has no qualms performing as it should. The modules are doing what it "says on the tin". Thanks to the SCAN team for the prompt delivery (delivered on the day they said they would be). Good piece of kit and well worth buying ...

Rated 4 out of 5 by from Job's a good'n Put them in the PC, they worked. Overclocked them a little, they still worked. No errors no problems. Cheaper here than they are going second hand on eBay (when I was buying). And delivery was fast, next day.

Rated 5 out of 5 by from Product works as stated. This product simply does everything as stated, Enable XMP in bios and re-boot. Those most important things for me are a 100% stable PC and limited power usage to keep it quiet. Therefore I don't bother overclocking and cannot comment on that.

Rated 4 out of 5 by from Good product I had to enable XMP profile in bios to get the specified 2666, it works fine, there appears to be no issues, its working ok in dual channel on my MSI X370 SLI PLUS Mainboard.

Rated 4 out of 5 by from A thing of beauty I probably need to get out more but these are very fine looking sticks of RAM. Only comment is to check that your system is running them at the correct speed (multiplier). My Asus 370Z motherboard stuck with the default multiplier meaning they were running at 2133Mhz. I didn't realise until I opened the Intel motherboard tuning utility - a quick trip the BIOS and a change - and then they were running at 2666MHz...

Rated 5 out of 5 by from Excellent Memory Used on Asus Maximus X Hero. Went to XMP profile no problems and works fine. Would recommend. Excellent service from Scan.

Rated 5 out of 5 by from Works well with a Ryzen 5 1500X Bought this to go with a Ryzen processor and it all worked well. I did have to change a couple of settings in the BIOS to get the RAM to run at 2666MHz but there were no problems. Up until that point it just ran at 2133MHz.

Rated 5 out of 5 by from Does the job nicely I brought these to go with my new Ryzen 1700 Build.. These are not Samsung Bdie chips but Hynix chips. They are paired with My Tomahawk B350 MOBO. Though not on the QVL of MSI for this board on Corsairs site they have been tested on the AM4 platform so QVL by Corsair. They do work on my MOBO at the stated speed though I have lowered the timings to 14-16-16-34 which work just fine . Latency on my system is 84ns I cant get them lower but it is more a case of how Ryzen infinity fabric works as to why the latency is such. I bench tested these using various bench testing software. apart from the relatively high latency for my setup (specific to Ryzen) the read write speeds are top notch. Very pleased with their performance. would recommend.
