Crucial 128GB Kit (2x64GB) DDR5 RAM 5600MHz (or 5200MHz or 4800MHz) Desktop Memory Kit, UDIMM 288-Pin, Compatible with Latest Intel Core and AMD Ryzen 8000 & Above – CT2K64G56C46U5

Item safely received and tested to work to specifications.

ドスパラで買ったBTOゲーミングPCに付けました。 理由はRUSTをミディアム設定でやりながらYouTube見るとメモリ使用率が80〜90％となりカクつくから。 ３２→１２８GBの増設です。 カクつきはなくなりました。 まあ、わかってたことですが上記使用に対しては正直オーバースペックでした。 同じことしても8〜11％くらいしか使ってません。 ６４GBで良かったかも。 まあ、要求は満たせたので満足です。 以下PCスペック CPU I7 14F GPU RTX5070 旧メモリ サムスン 16×2枚（32GB） 新メモリ クルーシエル 64×2枚（128GB） 2026/3/7追記 さすがに値段が上がりすぎている。2025年7月に買った時は56,380円だったのに、こんなの誰も買えないよ、、、 今も問題なく動いてくれていますが、、、、

Glad I bought this when I did, because it probably costs x2 now.

Works flawlessly at both EXPO settings it displays in BIOS EXPO settings (5200 and 5600 with different CL settings between the two, the latter more relaxed, obviously)... That is with 2 DIMMs to a total of 128GB RAM, as intended, with all motherboards (ASUS, MSI, Gigabyte, all fairly budget B650 or B850 based ones) I've seen so far, provided the BIOS has been upgraded to one from March 2025 or later. Compared with a nominally faster and more expensive option of buying 2 sets of 2 faster DIMMs (DDR5-6000, CL30-ish, 32 MB per DIMM), a fully stable operation (as reported by Memtest86+ and not only) achieved at a better overall performance at a lower price. Using 2 sets of the item - for 256GB total RAM (all 4 slots occupied) appears possible as well, although at lower settings. That's for a Zen5 CPU. A Zen4 Ryzen 7 7700 may require somewhat relaxed settings, even with just 2 DIMM slots used for the total of 128GB on some boards. If you absolutely need a huge RAM amount at a reasonable speed and price, this item may be an excellent solution.

not the fastest memory, but a great value. no problems.
