Crucial Pro 128GB Kit (2x64GB) DDR5 RAM, 5600MHz (or 5200MHz or 4800MHz) Desktop Gaming Memory UDIMM, Compatible with Latest Intel & AMD CPU CP2K64G56C46U5

I needed a ram upgrade for a home lab cloud server I built last year, and these were the best bang for the buck I could find. I tested the first pair, which clocked in at 5600Mhz without any tweaking and passed (2) Memtest86+ passes without error. Transfer rate showed at about 28GB/s, which is pretty good. I installed the 2nd pair, and the Motherboard down clocked the set of 4 x 64G to around 4400Mhz. I changed this to XMP at 5600Mhz, and the system booted without issue. I ran memtest86+ for 4 days, and have had no errors (it takes about 4 hours for the first pass, and around 10 hours for each subsequent pass). Very stable ram, with no issues. Highly recommend.

I received these and immediately ran a stability test for about 20 hours utilizing the XMP settings. It passed all the tests, and have had zero memory stability issues in day to day use. It also has dual settings for Intel and AMD. This is useful as sometimes "Intel specific" memory requires a lot of manual tweaking to get working with AMD (looking at you Corsair). The voltage requirements are very low compared to other DDR5 memory, but the tradeoff is the timings are very loose. For my purposes, I would rather the stability and lower power draw over manually tweaking further, but this isn't exactly performance memory like some other brands make.I'm using it in an Unraid server with several docker containers, so I was looking for a larger capacity. These should fit the bill and aren't super expensive compared to Hynix based modules (which "usually" offer more performance at the expense of more voltage).

Easy to install. Had to update BIOS at the Dell website, but all in all, it was pretty easy. Unfortunately, I couldn't get the existing two, 8 GB RAM modules to work, but the new two, 32 GB modules are more than enough and work great! Maybe someday I'll add two more 32 GB modules. The computer is much faster, and the video editing software has been a lot easier.

I was able to get 2 pairs of 2x64 GB RAM sticks working at 5200 Mhz. For B850 motherboard users with AMD 9xxx series processors, go into the BIOS and pick the EXPO II profile at 5200 Mhz. If you're stuck on first boot, try booting with one pair and complete memory training before installing the second set. Otherwise, the memory will default to 3600 Mhz on 'Auto' mode.

I bought an Asrock Taichi Lite Z890, within literally minutes of its release.I intended to have 192GB RAM from the beginning. I’m in to video editing (DaVinci Resolve) and AI photo editing. Occasional VM. I’m no gamer / overclocker by any stretch. When you check OVL for this MB; there are currently only 4 DIMM brands/models which 4-slot DIMM config is tested by Asrock. Technically; you are expected to buy a tested set of 4 (from manufacturer) which guarantees exact match of all timing characteristics between 4 modules. Currently only Corsair Vengeance sell set of 4x48GB DIMMs for about $600. Instead, I settled on Crucial CP48G56C46U5.C16B and decided to go on two steps. I first bough a pair of 48GB (96GB kit no: CP2K48G56C46U5). These are 5600MHz DIMMs which happened to have both Intel XMP 3.0 and AMD EXPO support (unlike Corsair). All 48GB brand DIMM modules have inherently “2R” layout (two rows of chips on the board. Read: you have to sacrifice speed – for that capacity). When you look at Asrock web site; for this MB it warns you that for 2DPC 2R (read: 4 DIMM modules in use – all 2R); motherboard will only let you run them on 4400 MHz natively. You can overclock that config to 5800 MHz+, which I have no intention of doing, at least yet. Whereas if you only use 2 of above same modules (1DPC 2R); you can use them at their native 5600 MHz (or overclock to 6800+ MHz).Long story short; I plugged in my first pair (in to slots A2, B2) and booted up. In about 20 seconds MB very correctly tested them and settled on exact suggested profile (see pics). You really don’t need to engage XMP, as it is exactly same as JEDEC profile. I run benchmarking tests, using Aida64 (see attached). Same day I ordered a second pair of Crucial CP2K48G56C46U5. I plugged them in to slots A1, B1. Power on after a short prayer (!); another about 20 seconds and Asrock very smoothly settles on to expected 4400 MHz frequency. Followed by another set of Aida64 tests; not a single problem.As I intensively searched Intel Z890 chipset months ago; I remember reading that memory controller of Z890 is more robust & capable compared to Z790. That was the reason for me going by 2 separate sets of 2 pair DIMM kits (versus single set of verified 4). It worked for my above configuration. I also saved $120 doing that. Your milage might vary; depending of what MB / RAM you choose.As you look at to Aida64 memory benchmarking tests; by going with 192GB RAM (versus 96GB) I’m losing 25% speed performance on memory read and 28% on memory write. Of course; CPU or GPU performance is not affected from that at all. As I’m not a gamer; that’s fair game to me (pun intended?)

Installed and works just fine. Plug and play. To easy

excelente producto lo recomiendo

Works as a charm. It has a nice, slick look if you don't care about the RGB. It works as described with speed and stability. Expo support is just enough for me. With over 128GB of system RAM, I can still browse with the RAM-eating machine, Chrome, while doing some AI generation. It's worth it. I was struggling with just the 32GB earlier after upgrading to a DDR5 PC. I was previously using the 64GB in a DDR4-supported PC. in the recent builds, they say 2 RAM sticks put less straints onto your PC and actually goes faster than the 4 sticks. Which this item is perfect for.
