    • Good ram
Size: 32GB Kit (2x16GB) Style: 4800MHz
I bought four sticks of this 32GB RAM to max my system out at 64GB, and it’s been running perfectly. Easy to install, no issues with compatibility, and my PC feels much faster and smoother now. Great performance and solid value definitely recommend

    • Works Reliably and Cool
Size: 64GB Kit (2x32GB) Style: 4800MHz
I use these Crucial RAM 64GB Kit (2x32GB) DDR5 4800MT/s CL40 Desktop Memory CT2K32G48C40U5 modules (4 of them) a with Corsair RM1000x (2021) Fully Modular ATX Power Supply in a Phanteks Enthoo Pro Full Tower Chassis without Window Cases PH-ES614PC_BK in service for about one year as I write this review. For the most part, assembly was very easy. I do video editing, audio editing, streaming, wordprocessing, browsing and email with my setup. I use all of my SATA ports and even have a plug-in eSATA card for more ports. So most of my drive bays are filled. The dram and everything I have connected to my power supply and motherboard has been rock solid stable, and the case holds in all together. It just works exactly the way I want and have no anomalies. The power supply, motherboard and all components run cool in the case with an i7-13700K CPU, 128 GB of Crucial DDR5-4800 that is clocked at 5200 automatically set by the motherboard itself. My video card is a the very modest ASUS GeForce GT 1030 2GB GDDR5 HDMI DVI Graphics Card (GT1030-2G-CSM) because I transitioned my ancient setup from MBR to GPT and needed to be able to boot the old system in the new motherboard before updating the Windows 10 Pro config to GPT UEFI and still be able to boot legacy devices. Everything just worked like a Swiss Chronograph. I strongly recommend this dram, the power supply, the case, the ASUS ProArt Z790-Creator WiFi 6E LGA 1700, the Asus video card, and am also recommending the Crucial MX500 SATA drives and Intel i7-13700K I use. Is all of this the fastest? I have no idea. Does it boot and work reliably everytime so far? Absolutely! ... show more

    • Works great.
Size: 32GB Kit (2x16GB) Style: 4800MHz
I initially bought two sticks at 16GB each. Works great with Linux. Then a few months later, I thought "I'll just buy more so those other two slots on the motherboard are filled." Do I need 64GB RAM? Probably not--at least not yet, but that's not the point. You see, Future Me told me to buy some RAM because it will become worth more than my computer.... ... show more

    • Great Value and High Quality all in one Package!
Size: 32GB Style: 5600MHz
Review Image by O.B. Juan O.B. Juan
My Dell XPS 8960 came with 32GB of memory (Ram) and a few years ago that was a lot of memory. However I often found myself pushing the 32GB limit of the XPS. So the first place I went was to Amazon to see what Crucial had to offer. I've had really good luck with every Crucial product I've bought and this 32GB memory card was no exception. It matched all the factory card specs and it inserted easily into the socket. After installation it integrated seamlessly with the XPS and I had no connection issues. During a recent heavy workload on my PC I was using right at 32GB but I didn't even notice it with the additional memory. Another quality product from Crucial ... show more

It works fine, though it did give me a scare when the computer took a good three minutes to boot the first time.

    • Workhorse RAM
Size: 16GB Style: 4800MHz
Fair choice in RAM. Decent for gaming and is very high quality for workload or office use. No heatsink on the unit does make it suboptimal for overclocking or having it in a low airflow case. The aesthetics are not bad considering how plain the object is. As for it being DDR5, the provided speeds are excellent for anything. Price point is sweet and I am happy with the quality and performance being where they are for the money. ... show more
