Crucial Pro 64GB DDR5 RAM Kit (2x32GB), 5600MHz (or 5200MHz or 4800MHz) Desktop Memory UDIMM 288-pin, Compatible with 13th Gen Intel Core and AMD Ryzen 7000 - CP2K32G56C46U5

It’s a pretty good RAM. It looks good for me, it doesn’t have any RGB or something (I personally prefer). Its installation is plug and play, just remember to activate EXPO. It’s stability it’s okay at 5.200MHz. It functions as expected.

Failures of the AM5 CPU's memory controller lead to requiring 2 DIMMs, not 4, so here I am purchasing this 2x48GB kit for content creation. Asus motherboard picked them up immediately, worked at rated numbers. Started raising the speed, kept raising it and it kept stable, over and over. Ended up at 6400mt/s with no changes to voltage or anything else other than the raw speed. Stable for a week now, no issues, can probably go higher but haven't had a reason to try. Great RAM. CAS latency is not the best but that is a meaningless number these days since everything is normally queued up for the RAM, so only the initial cast is delayed, and we're talking a few nanoseconds here. Raw speed is all that matters and this RAM has it.

Great price to performance so far. I had to install one at a time and let the ram "update" please review ddr5 for more info. After that it was an easy install and should fit most pcs with the smaller profile. I easily updated this in the BIOS as well. Cant beat this quality for the price

Works flawlessly. Super stable even with XMP or EXPO enabled

Perfect fit for my Alienware R16 with a 14900KF processor and a GeForce 4090. Easy installation and was instantly recognized. Running at the advertised speed and much beefier than the OEM memory modules. Went from 32 DDR5 to 64. Glad I made this purchase. A pretty good bargain as it's a relatively cheap upgrade.

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?)

Great ram, good price to for what I got and I plan on adding two more sticks. Used in my Intel ultra 265kf build with a gigabyte aorus wifi7 motherboard x890 chipset. So far it’s a monster rig and I want to cap it at 192gb ram. Lots of ram helps with huge audio projects let alone if I do anything with video but suppose gpu helps more with that. Anyway great ram and the speed is more then enough at 5600mhz. That is quite the high bus speed across the board and it does load windows 11 about 35-40% faster with what I got and a m2 drive vs the ssd/3770kf rig with 33gb at 106mhz.

Unsure if this was causing issues with an AMD-Asus build as part of a trifecta of failures either by the CPU or motherboard, so going to knock all three a start for failure. It's ram. It plugs in the way you would expect and one pair worked fine. Two pairs caused boot failure. Slower transfer speeds and latency (hence the cheap price per GB) but if performance isn't your main, they work.
