Corsair CMK128GX4M8A2400C14 Vengeance LPX 128GB, 8 x 16GB DDR4 DRAM 2400MHz C14 Memory Kit

Upgraded a ten-year-old Asus X99-A motherboard from 16GiB DDR4-2400 to this kit of 32GiB DDR4-3200. Given the age of the motherboard, having been released near the dawn of DDR4, I was concerned it might not be able to handle the higher clock speed. But a few small tweaks in the BIOS, and the system booted into the new RAMs and completed four passes of MemTest86 without issue. I even got an almost 20% memory bandwidth boost as measured by `stressapptest`.Perfect outcome; no notes.

Bought for a PC build. Item as described and arrived quickly.

Excellent value. Quality seems impressive. Everything fit and worked perfectly. Upgraded from 12 GB (one 8 GB and one 4 Gb) to 32 GB (2 16 GB). Took less than 10 minutes start to finish. Made a noticeable difference in video editing.

Fit right in fantastic upgrade from the single 8 gig stick i was using before

**Motherboard:** MS-C767 MSI MAG B365M MORTARI've found multitasking increasingly challenging since I purchased this gaming PC a couple of years ago. After investigating the source of the bottleneck, I suspected that the RAM was the issue due to various symptoms my PC was exhibiting. Applications responded slowly, and web browsers dragged my system to a crawl.After researching the best RAM options for my motherboard, I decided to upgrade to Corsair Vengeance RAM, known for its excellent performance at a reasonable price. The MS-C767 motherboard supports a maximum speed of 2666 MHz, so I chose this speed instead of the 3200 MHz RAM that initially came with the PC. Although it's possible to use higher clock speed RAM with the MS-C767, I was still determining whether it would surpass the 2666 MHz limit. I also encountered compatibility issues when trying to install overclocked RAM, so I opted for the Corsair Vengeance modules, which are guaranteed to be compatible with my system.Removing the old RAM and installing the new modules was incredibly straightforward. Upgrading from 16GB to 32GB significantly boosted performance, noticeable not only during gaming but also in everyday tasks. As soon as you boot up your system, you'll quickly realize that you made the right choice.

From an enthusiast standpoint these are... Well, they actually do much better than expected, being a value set. But these things are full of ifs. You are probably saying, "why buy a corsair value pack if you want to overclock?" Well, sure. I convinced myself the money was more valuable than that last 0.5% of system performance. But these actually do reasonably well.Details:They come with two XMP profiles, one set up for 2666 at 1.20V and one set up for 2800 at 1.37V. ROG suggests that "most" DDR4 ICs can handle timings of 15-15-15-34-T2 at 1.40V or less. So here are my results.The 2666 profile handled 15-15-15-34-T1 at 1.30V and passed two iterations of memtest86. I was surprised they could handle T1, but then again I only have 16GB right now.The 2800 profile, though, is a bit tricky. I was able to make 15-15-15-34-T2 stable, but only at 1.47V. Long term effects of such a high voltage are not known this early in the DDR4 lifeline. Basically, running this you could potentially degrade the memory and wind up unstable again, then have to downclock or replace your RAM.The other wacky thing about their XMP profile for 2800 is the PCI clock. 126.96 Hz. This will do some maddening things to you unless you have a good CPU sample. The gist is this: at a 100 MHz Bclk you can reach 4.5 GHz and probably get stable at around 1.25 Vcore (I am running a hex, your mileage may vary with 5960x). If your Bclk is 126.96, though, you can't reach 4.5 - you get to choose between 4.44 and 4.57. You probably have a 1 in 3 chance of your CPU being stable at 4.57 GHz, and if you're like me you get stuck at 4.44 instead.So now you have to choose between 4.44 GHz @ 2800 15-15-15-34-T2, or 4.50 @ 2677 15-15-15-34-T1.There is something magic about that 126.96 Bclk. It seems like you could pick something else and reach 2800 with different settings - bus every other config I've tried (so far) to reach 2800 at a different PCI clock has failed pretty horribly. Like, reset BIOS, your system won't even post.Overall, this set does well, handles tight timings fine, even runs at 2800. But the 2800 profile is pretty awkward to work the rest of your system around. Again, not an enthusiast set, but I've put it through the whole course and these are my results. All 4 sticks work fine. For the competitive price and corsair dependability I gave it 4 stars.

great! for my motherboard GIGABYTE Z390 AORUS PRO WIFI

Easy to input, good price
