  • Fast, stable, consistent and awesome!
Size: 96GB (2x48GB) Color: Black
SUMMARY: Right out of the box this ram worked great. It has proven fast, stable and consistent across all my benchmarks and testing. I included the info in the pics for Jedec, timings, chipsets and my benchmarks. The top bench at 4501 was with my 6 gig boost on. This RAM kit is awesome and works great! I think I finally found my RAM. DETAILS: I have been building computers for over 20 years. who cares. I am not a gamer nor an overclocker, but I am a performance fiend. I had maxed out my old MB at 64 gig and did some hardware updates and wanted to get more ram. Apparently it is difficult to get 4 sticks working together at least at a decent performance, so I was left updating to 96 gig instead of 128 like I wanted. Now I actually want 192 but thats another story. I have been on the hunt to increase my RAM from 64 gig for quite some time while keeping as much performance as possible. For ref I have a 13700k on a new Z790 ddr5 mobo which I had to get some inexpensive ddr5 ram for my initial build because I could not find the performance, soze and price I was looking for. Normally when swapping out ram I have to turn off the XMP and any other BIOS toggles I may have like low latency and gear2 settings. I was so excited to install this ram that I forgot to do that. My system booted right up with this new ram. Normally it doesnt like I said. My initial RAM bench was awesome. Not only that, there are several benches I do that sometimes have issues and this ram worked great across the board. I even turned on my 6 gig boost which normally causes a couple of benchmarks to get flaky. This RAM made everything work better and was more stable than my previous ram, plus I didnt have to spend hours testing and tweaking settings. I was even able to run all of my benchmarks at the 6 gig boost which normally there are a few that will crash the system. I am super pleased and super surprised at the performance and stability of this ram. Also. my CPU bench is more consistent at around 49500 instead of fluctuating. My ram performance has increased on the threading. I still get intermittent latency between 35 and 36 with the 36 being the norm. My ram bench has been consistent over 4300 and my gpu diectx9 bench has been performing more stable. My ram read writes are fast but not consistent. Overall, I am getting great performance, great consistency and better stability. This ram is performing better than my 5600 cl28 which was tweaked pretty good cuz thats how I roll. This being 6400 CL32 at faster MHZ but higher latency performs better out of the box with the same bench latency in the 35-36 range which is great IMO. Super happy that I am getting the performance I want with 96 GIG. I also performed memtest86 under separate BIOS settings only doing 4 passes under each setting. With Low latency enabled instead of Auto, it passed, With Low latency enabled and 6 gig boost on it passed. With High speed and Low latency both enabled instead of auto, it passed. With High Speed enabled and Low latency enabled and 6 Gig boost on , it failed. IMO these results are better than I expected as the 6 gig boost will sometimes fail out previous memory sticks. On my mobo, I get better performance when I change the low latency from Auto to enabled and with this ram I was also able to use the 6 Gig boost which greatly improves performance without any errors in the Memtest. For reference, other ram I have used has failed when 6 gig boost is on or even enabling high speed and low latency at the same time has resulted in failures. So this Ram is pretty awesome in my book. I have not even tried tweaking timings, voltage or speeds as the XMP performance and stability is great as is. So if you need ram for modeling or virtual machines or 3d or even gaming this is the best price/performance you can get. In my humble opinion ... show more

  • Good memory and seems to be quite reliable
Size: 32GB (2x16GB) Color: Black
Bought 2, 2 stick @ 32GB packages for a total of 64GB of this for my new Z890 motherboard (Gigabyte) and it's working quite well, some 4 months in since assembling new PC. Did not get RGB and was not interested in it anyway and it was at a decent price for what I got. Only change was, should have bought a single package for 64GB but oh well, the decision changed after I bought the first package of 32GB. So ordered another identical pair days later to bring the memory to 64GB as I typically run up to nearly the full 32GB as it was on the old desktop. Even at 16GB, it was way worse, causing the SSD to page file swap more readily and unnecessarily. ... show more

  • I Will Always Use Corsair Memory - This Is Why
Size: 64GB (2x32GB) Color: Black
I have been using Corsair memory (and also GSkill) for many years, and it has never let me down. No issues whatsoever. I just recently put together a new build, and I needed DDR5 RAM, but did not know how much speed or latency I needed. And I didn't need a RGB set - my rig is running with no RGB and all of the mobo and video card lights disabled. For the value and money, I went with what I know that works: Corsair. This purchase was right on time, because it had the size (64gb - 2x32 and I rather run two sticks instead of the 64gb - 4x16) I also found out that running the higher speed in two sticks eases stress on the memory controller on the motherboard. Plus this set has better latency (CL32 vs CL40). And the price was right. After installing on my z790 motherboard, I ran the sticks thru Memtest86. No errors and both RAM sticks passed. Since I have other Corsair components (case; AIO cooler: power supply) I can make any adjustments in the iCue program. I only enabled the XMP in my bios, and so for so good: it is running at the advertised speed with out issues and is stable. I probably won't overclock or tighten up timings. My browsing is much faster than my older Corsair kit, and no crashes in Windows or Chrome. I don't game, so I can't speak on that. But i use my computer for photo and video editing, and other work. I'm satisfied with my purchase. Well worth the money. ... show more

i have them running at 6400mhz with the xmp profile, so far after over a year of service as my iptv cameras NVR and Jellyfin server i had zero problems, zero lockups, zero blue screens, i'm running windows 10 right now but i ran Linux Mint for about 3 months and it was also super stable with the xmp profile on, definitely quality ram. ... show more
