Let's face it: the reason for purchasing Corsair Vengeance LED DRAM is for the pretty lights. Otherwise, more economical RAM could be used that have essentially the same technical specs. Installed in my build, this RAM works fine and the red LEDs do glow and look kind of impressive. However, the Corsair advertisements show the RAM blinking in a coordinated fashion but mine breathe independently of each other, and not even at the same frequency. The Corsair LINK software is supposed to control the LEDs, among other things. But while the LINK app seems to accurately measure the CPU, MoBo and SSD temperatures accurately, it does nothing to control the LEDs. I contacted Corsair and they responded quickly, saying that the software that will control the LEDs is still in beta and gave no estimate on delivery. So this RAM only gets three stars because of apparently misleading buyers by showing coordinated lights on their website but delivering something different. If the finalized LINK app delivers as promised, this post will be updated. In the meantime, I'm looking forward to reviews of G.Skill's new Trident Z RGB DRAM.UPDATE 3/19/2017: The LED function of these DRAM has improved a bit with Corsair's recent release of their updated LINK software. Now at least I can get both sticks to stay lit permanently and can adjust the brightness when they are constantly "on". But when blinking, each stick still has its own frequency and there is no apparent way to coordinate them.UPDATE 3/30/2017: A new LINK software update was just issued and it finally works as advertised. The rating is upgraded to five stars. The new software is a bit cumbersome, but it does effectively allow the blinking LEDs to be coordinated. You can even adjust the speed of the blink and the interval by which the grouped LEDs are offset. I really like this now.

Great memory from Corsair as usual, can't go wrong with them. Installed, activated the XMP profile, and they were running at 3200 with no trouble. I wasn't able to overclock much, but keeping at 3200 I was able to drop the timings a bit, overall very happy with my purchase. Also, the LEDs on these sticks look great... my main color scheme is green/black, but I like to rotate the LEDs in my case and these look good with all. May pick up another 16GB kit in the future, but that is probably a bit overkill for my needs (mainly just gaming).Definitely recommend this kit if you're looking for a quality 3200 kit that also looks great in your case, price is also very reasonable compared to their Dominator series.

I bought these for use with my i7-7700K @5.0 Ghz (1.32v) and ASUS PRIME Z270 motherboard. The Corsair Link software lets you control whether they're static ON or going through a slow "breath" blink on and then off again pattern. The four modules don't do this in a synced pattern, but the effect looks like the Warp Drive on Star Trek kind of (except white).The SPD timings only come with 2133 Mhz and 3466 Mhz XMP options, so if you have trouble running them at the "stock" overclocked speed, which can be a thing when overclocking Kaby Lake CPUs you'll need to look up timings for 3000/3200 Mhz etc to find appropriate ones and set them manually. I didn't have any problem running them at 3466 with my CPU and board though, so it wasn't an issue for me.The LEDs do actually look white, not a blue or green off white like some White LEDs have a tendency to do (or pink in the case of Red LEDs). And they're not RGB, so they'll only do White. The Aura software with from ASUS turns them off, but firing up Corsair Link gets them going again. I also have a Corsair H115i AIO CPU water cooler with an RGB LED on the top. The LEDs have a "frosted" sort of finish, so my CPU+RAM area of the board and case LEDs (Corsair 750D Airflow) are white with my motherboard, graphics card, and 400mm Phantek LED strips plugged into the motherboard have are set to red giving me an overall aesthetic I'm pleased with.Although they weren't on the ASUS PRIME Z270-A's approved list they do work with the XMP settings without issue and provide higher bandwidth in synthetic tests than quad channel DDR-1600 Mhz, so the performance is good. I'm pleased with them.

I always use Corsair RAMs in my enthusiast and high-end builds. I have not used the LED RAM kits before so for this build I was going with a blue theme and I wanted a little bling to jazz up my DDR4 3200. It makes the RAMs pop that's for sure, and if you use Corsair Link software you can change the pattern and intensity of the LEDs etc. *(I prefer static and to decrease the intensity - These are very bright out of the box) All in all, pretty cool. I might use again if a build needs some extra jazzen up. One thing you need to watch is that these Kits are tall so make sure your chassis has plenty of clearance especially if top mounting an AIO or radiator or even in some smaller chassis, top mounted fans. As far as Corsair Vengeance performance, its top notch
