I have installed 16GB and it has never caused me any problems, but for some reason it shows that only 13.9GB is usable

Cheap, affordable, and durable memories from Corsair, they also have a bit of overclocking capability. Beautiful heatspreaders with a low profile and very good assembly. For this price, it's the best option - and without lights like a Christmas tree.

Owner of the product for about a month now and I have to say it's perfect for budget builds. Cheap and high quality (we're talking about Corsair) but we're talking about 8GB, so I recommend getting the 16GB set. I regretted getting only one module so I got a second one. It doesn't have RGB and all that, just a simple and sleek black heat sink that does its job very well. 10/10 if you don't care about RGB and want budget RAM. Also, make sure to check the BIOS and the speed it's running at because for some reason it's set at 2133MHz when you first install it, so just set it to 3000MHz and you're good to go.

I had an 8 GB single channel, I played around with the timings in the BIOS and it worked fine. After two months, I got another one and it was immediately recognized by the BIOS. Now they are running in dual channel and the performance has improved. With the GIGABYTE B460M DS3H motherboard and Intel Core i3-10100 processor, I am satisfied and would buy it again. I can even do it because I have two more slots waiting! The only thing I wanted at first was to enable the XMP profile in the BIOS, but only for the first RAM. I adjusted the timings to their proper values because now I am satisfied with the dual channel setup!

For those interested in overclocking, I couldn't reach 3600mhz with Ryzen 3rd generation and have it be completely stable. So the highest it can go with 100% compatibility is 3466mhz, but with looser timings than at 3200 and 3400 where it runs at 16-20-20-38, so I ended up at 3400. At 3600, it wanted 18-22-22-42 but as mentioned, it wasn't 100% stable. Generally, it doesn't tolerate many experiments with timings beyond the default. Other than that, it's a great memory.

Combined with Asus B350 Plus - latest bios - and R5 2400g.

I enabled the dcop profile at 3000 to pass the timings and lowered the clock to @2933.
Because I had fails in the post, I increased the DRam Voltage to 1.36V and the Soc Voltage to 1.15V

I have it only for 1 month, it's great, I give it four because I am satisfied so far. If I had it for a longer time, I would be able to tell you more about it, but for its price, it is very good.

Very good and fast for its price.

Update 9/6/2020

I got another 8GB RAM stick and they run at 3200 with a slight OC. Unbelievable for their price!

The best value for money. Although relatively old, you can't ignore the 3000Mhz and cas 16 at such a price. On a B450 motherboard with Ryzen 5 2600, it initially ran at 2133 but with XMP settings, it runs at 2993 which is also the maximum speed for 2nd generation Ryzen.
Edit: I overclocked it to 3200Mhz without any issues and it runs perfectly fine.

It was paired with Gigabyte B450 Aorus M and AMD Ryzen 3 2200G. At this cost, it includes a cooler. It only has one profile in the bios, you select it and it simply works at 3000MHz. It uses Micron B-die. Since I am only running one memory dimm, I will update for stability once I try it with two.

I have installed it on a b450 Aorus and it runs perfectly... At first, it was running at a lower speed but after I entered the bios and changed it, it synchronized at the promised speed... It is very reliable and so far (5 months) I have absolutely no problems.
Edited: 1.5+ years later, I am still equally satisfied and it will be installed again in a friend's new build. 2*8

Amazing build quality, very beautiful with its cooler. Bravo to Corsair. Easily overclocked to 3000, just be careful because it defaults to 2133. You need to enter the BIOS and change it. I haven't pushed it further, don't need to anyway. I have it with an i5 8600k processor and everything is perfect. 5 stars, very easily.
