Put in old optiplex desktop to make sleeper build. Works flawlessly. 16gb ddr3 is plenty for my games. Easy to install and despite ddr3 being a decade old these definitely have a modern look high quality.

    • A noticeable POP in speed! Pricing a bit steep at $67.99 (1600 is 7+ years old as-of 2021)
Size: 16GB (2x8GB) Kit 1600MHz CL9
I used this to upgrade an 8+ year-old PC from 8GB to 16GB, running Windows 10. NICE and noticeable bump in performance, not only from the perspective of the added RAM capacity, but also the CL9 latency was a 28.5% speed improvement over the CL12 of the previous RAM. My SSD 'felt faster' due to improved caching via Samsung Magician "Rapid Mode", and everything was just better. I am a bit of power user, even if I'm running an 8yo PC. 24+ hours in, system has been perfectly stable, no issues with RAM. Patriot is a brand I trust, based on prior experience with their products. Features Rating info: Easy to install - 5 stars, but I'm an experienced PC tech. Doing this yourself is easy enough, if you know about things like static electricity, dust, and 'other'. If you don't know how to upgrade RAM, find some YouTube videos about it. For gaming - Yes, I am a gamer. Things will run faster because of the extra RAM. For FUN, I did create a RAMDISK (4 GB), and loaded the notoriously slow (beautiful otherwise) game GOTHIC 3 (2006) onto the RAMDISK. Teleporting, and other things were SUPER FAST AND SMOOTH!! Value for money - 2 stars might be generous. PC3-12800 RAM is somewhat outdated, especially for gaming PCs. It should not be priced where it is right now ($67.99), and really should be down around the $39.99/$49.99 price point. I probably should've bought faster DDR3 RAM, used it for now, then moved it to a semi-newer PC in the future. Personal note: I AM due for a new PC, just been holding off, just a bit too long due to Covid-19. Stay healthy, folks! ... show more

    • Good memory
Size: 16GB (2x8GB) Kit 1600MHz CL9
works as it should . this was added to my 2 empty mem slots and it booted up just fine the first time. Different brand than my other but slot and speed are the same , timing was different but it works well. Passed a 1 hr Mem test program with zero issues .

    • Decent RAM that works like it should.
Size: 16GB (2x8GB) Kit 1866MHz CL10
OK Ram, not going to wow you with benchmarks, but since it's mostly on the lower end of the price range it is a very good value for the money. It certainly has a quality look to it, but I'd say it's just middle of the road RAM wrapped up in a nice suit, for a very good price. Pro's: Looks good Doesn't cost any more than 'naked' sticks. Con's: Not much improvement over the 'naked' sticks I tested it against cooling fins on this taller set could interfere with some CPU coolers. Recommended, but if you want benchmarks I've had better luck with Corsair Vengeance, or G.SKILL Ripjaws for similar or slightly more money ... show more

    • Works as advertised.
Size: 16GB (2x8GB) Kit 1866MHz CL10
Ordered this to replace my old Corsair 1333mhz kit that I've had forever and lately had been dying to get rid of. This Patriot kit is noticeably faster; I could immediately tell the difference in a variety of tasks (gaming, video streaming, etc.) Even just doing something as mundane as dragging a window across the desktop or closing out of a game is noticeably smoother. One major benefit is that Patriot has a very high compatibility with motherboards in general; so if you have a DDR3 board, the Viper line is pretty much guaranteed to work with it. As a sidenote, some people will tell you that memory bandwidth doesn't make much of a difference, and I will tell you that's false. It largely depends on what you're doing and how low you were to start with, as there are diminishing returns the higher and higher you go. If you're at something like 1333mhz, jumping up to 1866mhz or more is a sizeable boost in bandwidth and will provide an immediate benefit to almost everything you do on your machine, especially if your CPU is overclocked. It can also provide a few more fps in many games as well (especially at higher resolutions where bandwidth becomes more important), if that's your thing. All in all, this Patriot RAM is pretty good stuff and I don't think you'll be disappointed. ... show more

    • Great value for excellent performance
Size: 16GB (2x8GB) Kit 1600MHz CL9
I purchased two of these memory kits for an older Shuttle SH67H PC with an Intel i5-3470 CPU @ 3.20GHz and they fit and perform very well. Overall a very good value for a trusted name.

I love my Patriot Viper 3 DDR3 memory! Upgrading my RAM significantly improved my computing performance. My software runs smoothly on Windows 10 Pro without freezing, even when using a large number of internet browser tabs and numerous other software programs running in the background. Everything now operates remarkably well! I highly recommend this memory. ... show more
