    32GB of Performance for Gamers & Professionals

    There are a few reasons to upgrade your computer memory. Either you need more memory or you need more speed. In my case I opted for both. The Crucial DDR5 Overclocked desktop memory delivers. It's stable, it's fast, and it provides plenty of RAM if you're a power user, or you're pushing your system during one of those gaming marathons. *Build Quality - There are 2 heat spreaders but they still sit lower profile for those smaller builds. There are 2 sticks, all black, with aluminum heat spreaders. Even with the heat spreaders, they are low profile, and lightweight. The feel sturdy, which is important when snapping them in. There's very little flex. *Installation - Installing the Crucial DDR5 Overclocked Memory was a breeze. I installed 2 sticks of 16GB all black. I have an Intel build with an I7 14700F but it also supports AMD 7000 series and up. *Specs/Performance - Timings are 38-40-40-84. Faster memory means one thing for gamers, higher framerate. Depending on your upgrade, you will definitely see a jump in frames. I'm a gamer, but equally important is my upgrade from 16GB to 32GB. I now have some breathing room when I have several apps running at the same time, or a ton of tabs open on my web browser. Enabling XMP will get your timings down to CL38 and your speed up to 6400. Crucial has always been a trusted brand when purchasing memory for my computers. As computers and games demand more, it's nice to hit the sweet spot with the DDR5 6400 memory. There's faster memory out there, but considerably more expensive and less value. 16GB is enough for the casual user, but if your work demands it, or you want to squeeze out every frame available while gaming, this is it at 6400 and 32GB. The icing on the cake is DDR5 tends to offer an even greater return on some productivity workloads involving compressions such as zip files or creative photo work. *Pros* *Stable (Even at these speeds, it remains stable) *Hits the sweet spot at 6400 *Timings are adequate *Heat spreaders generate less heat *32GB will provide enough ram for several years *No RGB, Looks professional *Frame rates will improve *Needs Improvement/Suggestions/Cons* *Some gamers might prefer RGB sticks *Intel 12-Ultra 200S generation only, AMD 7000 series or greater

    Crucial Simply Does RAM Right

    I needed to upgrade the RAM in a workstation to 32GB of DDR5. I didn’t want any RAM with RBG and needed a low profile. So of course, I go to one of my staple brands to check what they have, Crucial. That is when I found a kit of Crucial Pro OC Gaming 32GB (2x16GB) DDR5 6400MHz, which was a perfect fit for my build. Pros: - Simple and good RAM, No RBG. - Fast and Stable transfer rates for both Intel and AMD. - Low Profile heat sink. Cons: - None. Installation: The Crucial Pro OC Gaming RAM was as simple as RAM installs go; open package, open case, install on motherboard, go into bios to enable XMP/EXPO, and Restart. Done. The RAM worked at the advertised speeds the first time without any issues. This is one of the main reasons I chose Crucial, the RAM works exactly as I want it to. The heat sinks on these were the perfect height to not conflict with the air cooler, which has a fan over the RAM slots. Speeds: Most of the time, when you install a new component in a PC, it is best practice to go into Bios afterwards to confirm the hardware shows up correctly. Consult your Motherboard manual for how to get into Bios, for me it was spamming the “Delete” key on boot. For the RAM, the XMP or EXPO settings need to be enabled to achieve the advertised transfer rate, in this case that is 6400MT/s. After enabling XMP, I saved and restarted normally with no issues. After restart, the RAM showed up in Task Manager at 6400MT/s. I ran a few quick tests without issues, then it was off to work. The computer felt so much faster with the increased RAM. I was able to open more applications and work between tasks without the system slowing to a crawl. Conclusion: If you need a simple and fast set of RAM to upgrade your system to 32GB, without the RBG, the Crucial Pro OC Gaming RAM is a solid upgrade choice with the 6400MT/s and simple design. I’ll continue to use and recommend Crucial RAM for many future builds.

    Great, stable memory for gaming and everyday

    Adding Crucial memory is probably the best upgrade I've made to my desktop machine. I have an Acer Predator Orion 5000 gaming machine with an i7 processor. It came stock with 16GB of memory which I always thought was a bit slim. Upgrading to 32GB made a noticeable difference in not only games, but in my every day usage as well. Even though the Predator is by nature a gaming computer, it serves as my everyday machine too. Looking at my memory usage, I'm on average at just over 14GB. That's with a word editor program open, my Photoshop Elements program for editing photos and lots and lots of browsers with at least a dozen tabs in each one. So I guess it's safe to say that my previous 16GB of memory was certainly at the limit just in everyday usage. These new Pro Overclocking series UDIMM modules are certainly capable of giving me the added memory space I need, and on top of that can be over-clocked for gaming. I personally don't overclock my machine, but you're welcome to with this 32GB kit, which supports both Intel XMP and AMD EXPO profiles up to 6400MHz. These modules are really cool looking with their outer shell design. The “heat spreaders” work to dissipate heat and keep them cool. I really like the matte black color, but since there's no integral lighting, you may find that getting the white color would show them off better inside your case. I replaced my two stock 8GB UDIMMs with the two 16GB UDIMMs. It was about the easiest upgrade I could have hoped for and took literally about five minutes to complete (which also included opening up the case). They are plug and play for the majority of us, and all I did was power up and look in my system settings to see that the Installed RAM now shows 32.0 GB. If you're interested in overclocking, you'll probably need to go into your BIOS and make a change there. Most machines differ with what they call that option, so it's best to look in your user manual for guidance. Overall, using my machine after upgrading to the Crucial RAM is a better experience. Everything just seems to run very smooth. No glitchiness, and no waiting for programs to finish working on something. As far as games, I like playing first person shooters a lot. DOOM and DOOM Eternal look absolutely amazing when all the video options are maxed out. The benefit from the extra memory was plain to see. If you were always interested in seeing the benefits of being able to turn on ray tracing effects, you can now do that without fear that you're game play will suffer because of it. I'm seeing my games in a whole way, and I love what I see! There's no lag or stutter (which I didn't get with my 16GB of memory, but then I didn't have all the video options topped out). With the more advanced games coming out, I think it's safe to say that soon the norm will be for gaming machines to come with 32GB instead of 16GB. My machine isn't even a year old and I see this happening already on a lot of systems. So, upgrading your memory can easily send you down a rabbit hole trying to find out exactly what specs your current memory has and which memory devices are actually going to work in your system. Before I chose this upgrade kit from Crucial, I made it a point to visit their website and use their extremely helpful tools to find my exact machine to see which DDR5 modules will actually work for me. If you can't find your machine listed, you're probably just looking in the wrong place. They have thousands of machines listed and any manufacturer you can think of. I don't know how they do it, but they cross reference your machine and show you only the RAM that will work in your system. It's pretty amazing, and I didn't run across any other memory manufacturer that had an even remotely good product finder as Crucial. They are tops in the industry, and it's easy to see why. I love the added RAM and I'm really glad I upgraded.
