The 32GB RAM kit review showed high positive feedback, mainly its stable performance at 4000MHz. It is highly compatible with AMD Ryzen Systems and x570 chipset paired with R9 5900x CPU. The RAM's aesthetic lights and design were appreciated, and it also offered a good value for money.

  • 💡 Aesthetic lights and design
  • 💰 Value for money

Should I Buy It?

The RAM kit has proved to be high-performance and stable, with an appealing aesthetic and good value for money. Though there were a few cases of instability at 4000MHz, the overwhelming majority of users were pleased. The product is recommended for purchase, especially for AMD setup users.


  • Works Great!
Was able to get the rated 4000mhz with the rated CL18 timings by simply enabling one of the A-XMP profiles in BIOS. Motherboard is an MSI Pro b550m VC WiFi with a Ryzen 5700x CPU. Have had it installed for about 1 week now with no stability issues. This particular model number was not on my MB QVL list but I saw a few others with the same cpu and the same b550m chipset say it was compatible at the rated speed so I decided to get it. Glad I did because it was a decent value. Easy to install, took the old out and put the new in and my pc recognized it instantly on the first boot. Performance has been great, really snappy and quick. Plus jumping from 16gb to 32gb of ram I have a lot more headroom now. ... show more

  • Great ARGB, Fantastic Performance.
G Skill ram is top notch, solid speed, decent latency. The fastest DDR4 I could find, not quite ready to move on to DDR5.

  • Beyond what I expected
I unfortunately can’t afford to upgrade to an AM5 board to use DDR5 ram so I decided to try different brand of RAM I was using, and I am beyond happy from the switch. The performance is far beyond the expensive Corsair Vengeance RGB Pro I was using. The sticks have a higher overclock voltage than the Corsair sticks I was using, at 1.4v instead of 1.35v then I knew I’d be able to get past the 4000mhz clock I was stuck at with the Corsair sticks, now I’m currently running the G.Skill Sticks at 4200mhz and could probably run it higher but haven’t tried yet to see if it would be stable at 4400mhz. I put on Stalker 2 and my frames only increased by 2-3, not by much but my computer just feels more snappy now that I have 32Gb of RAM instead of just 16GB. Compared to the price of the Corsair Vengeance RGB Pro these sticks are unbeatable. I’m now convinced that I will never use Corsair RAM again as the price for performance cannot be between with G.Skill. My only con is the RGB. With the Corsair RAM it was very easy to setup the RGB. But with the G.Skill RAM it tries running through my motherboards RGb which I do not have setup. I tried installing software to control it from G.Skill but it did nothing. So I’m pretty sad that the RGb is running a bunch of colors compared to my RGb set by my liquid cooler and other RGb fans. If you’re trying to decide Corsair vs G.Skill, G.Skill is far superior. Never will I go with Corsair RAM again. ... show more

  • My best upgrade purchase yet
I've needed to upgrade my ram for quite a while, I was running 2 8GB sticks. It was hard to play some of my favorite games, especially Minecraft or Project Zomboid without it eating up most of my ram. I did some research to see what sticks were compatible with my pc on pcpartpicker and these were the cheapest, but the greatest upgrade I can get so far without having to cough up a lot of money. I saved up and got these 2 sticks for a total of 32 GB, it has been my best purchase yet. Installing these sticks was easy and fit in my pc without any issues. They came packed in a nice little box as well! After installing and turning on my pc, I noticed they had an rgb feature, which I didn't realize in the title of the product, but it's a bonus for me since my entire pc is rainbow rgb. Overall, these sticks are great, they fit the aesthetics of my pc set-up, is compatible with my other parts, offers more memory capacity, and has made my gaming performance so much better. ... show more

  • G.Skill Trident 4000
These memory sticks work really well after I've installed both of them, so far no major issues on boot and while my PC is running, and they were fairly easy to install. Plus in a specific rgb software I have they're supported and each stick can be individually customized. If you want high speeds at a affordable price I recommend these sticks. ... show more
