Corsair Vengeance

Reviewed in the United States on April 14, 2024

Style: 2666Mhz C18Size: (2 x 16GB)Color: DDR4Verified Purchase

I've used Corsair 4 different times, and have only had one 'corruption' issue out of those 4 times. As you see, I already changed my HP laptop RAM to a Vengeance DDR4. It came installed with 8GB. I attempted to upgrade to 16GB (2x 8GB) (my laptop is supposed to be dual channel, but only has single channel setup). So, I replaced it with a new, single, 8GB (same that was already in it). Plug and play with no issues at all. Started right up.. SO, I ordered a single 16GB. BUT, it didn't work and said files are corrupted and I need to create a USB recovery drive.. so, I had to replace back to the 8GB. I'm going to attempt to create a recovery USB and do it that way because I desperately NEED more RAM ASAP and not about to buy a new laptop as this one is less than 2 years old.
I wonder if it's simply the stick itself that is corrupted and if it will work if I get a new one.

These are great. Still working super after several years

Reviewed in the United States on February 13, 2024

Style: 2666Mhz C18Size: (2 x 16GB)Color: DDR4Verified Purchase

I bought these several years ago, and they're still working great and performing like new several years after purchase, and long after the stock RAM sticks that came with my laptop died.
Corsair is a smart buy, and a monolith in the RAM market. They've been in the RAM game for a bit and they know what they're doing.
Buy some Corsair RAM, but, for the sake of avoiding a bad experience if you don't know what you're doing or looking at when you buy computer RAM, ask some computer geek people to look at what exactly you need, because if you get the wrong clock speed, and mix it with other RAM of different clock speeds, different latencies, and other bits of techno-babbley stuff, you might not have the best experience, so, there's more than the GB number you need to know.
You'll need to know what generation of RAM works best for your computer DDR4? DDR5? DDR ... what?, what form-factor your computer needs (SO-DIMM in my case for laptop), what clock speed your computer works best and is compatible with (if you get a high clock speed that your computer doesn't support, then it probably won't work, and if you get a really low clock speed, you could make your computer even slower), ... and then there's a latency group of numbers, but, this isn't as important unless you're squeezing for maximum performance and if so, then you'll want to be picky.
Anyway, that's enough of my babble.
Buy Corsair RAM. Their in the top of RAM pick choices, and I expect they always will be.

It works, but that's no guarantee of performance improvement

Reviewed in the United States on May 1, 2024

Style: 2400Mhz C16Size: (2 x 16GB)Color: ddr4Verified Purchase

Everything I had read online suggested that increase RAM on my 2017 Imac would resolve the slow loading issues I began experiencing about a year ago. So I tripled the onboard ram and...nothing happened. Apple tech suggested it's just that newer operating system updates don't play nice with older machines, increased ram or not. But that's not the chip's fault. It was stupidly easy to install. Just beware.

Easy install and a must to upgrade your laptop’s RAM. Some games such as escape from tarkov accidentally use all of your RAM on loading in and crashes so going from 16gb to 32gb actually fixed it. Just a common issue with games nowadays since they often drop unfinished.

I bought 2400MHz ram because that was the limitation of the motherboard for my AMD 2500u all-in-one system. So, this is all I could use. But this ram is twice the capacity of what the computer was previously, thanks to this kit. Great ram timings and reliable brand. As always. 👍
