Crucial 128GB Kit (2X64GB) DDR5 RAM 5600MHz (or 5200MHz or 4800MHz) Laptop Memory Kit, SODIMM 262-Pin, Compatible with Latest Intel Core Ultra and AMD Ryzen 8000 & Above – CT2K64G56C46S5

Excellent product. I bought an AMD Ryzen AI 9 HX 370 laptop with 64GB RAM and an eGPU enclosure with an Nvidia RTX 5070 Ti 16GB card as an AI test bed. It's functional but can't load bigger models like "Qwen/Qwen3-Coder-30B-A3B-Instruct" (56.8GB from Huggingface) due to memory exhaustion with only 64GB RAM. 128GB barely makes everything work with just a python inference jupyter notebook and little else -- 15.6GB of 16GB on the 5070, 48.1GB of the 62.8GB shared RAM GPU pool, 2GB RAM for the Radeon GPU driving the displays, and the rest for whatever PyCharm, PyTorch, and Windows need. If you're playing with AI on your local machine, you'll appreciate the 128GB.

Works well without failures

I got the 128GB kit, CT2K64G56C46S5. Took the risk that it would work, as I am upgrading from the also unsupported 96GB kit but could not find anywhere that 128GB was compatible. I had the 96GB kit working in both a Minisforum UM 780XTX and a UM 890 Pro. I can now verify that the 128GB kit also works in both. Forgot to check speed on the 780XTX but works at 5600MT/s on the 890 Pro (only needed to upgrade 1 system for now). Was already up to date on BIOS on both so don't know if that is a factor, but would recommend latest just to make sure it is compatible. Using for home lab.

The 5 star review is for the RAM chips themselves: 128gb (2x64) DDR5. Installed them on a PC that was compatible without issues and the computer recognized them. Ran a test and showed zero defect. All good. Now a 1 star review for something that was extremely important for someone who value their purchase and money like me. These chips aren’t inexpensive by any means and my criticism is the manufacturer could have spent a bit more attention to packaging. These do not come in a box, just 2 chips sitting inside a plastic pack and WITHOUT any factory sealed tape, and the plastic wasn’t sealed by any means. Just pull the taps on top to open and you don’t even need to cut the plastic. There is no way to tell if the contents have been opened, used, manipulated or returned previously. I on the same order purchased also Crucial m2 SSD and the content came with sealed tapes on the box. Come on, Crucial, do better.

perfect, exactly what was needed.

Fast but time. Really easy to install in my mini-pc. Plenty of RAM to future proof my system for a long time.

One stick failed and crucial isn't honoring their warranty

Works! Thanks Crucial, now i dont need PC anymore. Lenovo Legion 5 Pro 16ARX8 Ryzen 9 7945HX. Update: One ram stick started to BSOD after 3 months. Update 2: Still not warranty replaced since July. Update 3: I got my replacement in January. For a first look works fine.

minisforumのAI X1 PROに使用

Excellent produit. Je les ai mis dans un ordinateur ACEMAGIC F3A AMD Ryzen AI 9 HX 370 Mini PC pour tourner des modèles LLM gros (Deepseek, llama, etc ). Ça marche nickel !

Tempi di consegna rispettati, RAM nuova in condizioni impeccabili. Mi spiace averla ordinata, a me serviva per PC scusatemi ancora!

Funcionan muy bien AOOSTAR GEM12 PRO MAX - R7 8845HS, algo extraño es que quise compralo otra vez pero ya no es posible.

Om 2x64GB DDR5 laptopgeheugen te kopen, heb je letterlijk geen keus. Gelukkig was de enige keuze wel kwaliteit. Helaas zijn de prijzen voor geheugen inmiddels verdrievoudigd, maar dat is nu eenmaal de nieuwe realiteit. Verder prima geheugen.
