Kingston FURY Impact 64GB (2x32GB) 5600MT/s DDR5 CL40 Laptop Memory Kit of 2 | Lower Power Comsumption | Intel XMP 3.0 | Plug N Play | KF556S40IBK2-64

This is high quality memory. It's Kingston "dual rank" 64GB DDR5 5600mhz ram (CAS LATENCY 40-40-40-84 @ 5600mhz) because single 32GB DDR5 sticks are all dual rank, and anything lower (16GB/24GB) is single rank. A 13th and 14th gen intel chip can accommodate 32GB (2x16GB) single rank @5600MHz, and 64GB (2x32GB) dual rank WILL CLOCK DOWN to 5200mhz, but the CAS latency also drops to 38-37-37-73 CAS Latency timings. I'm getting my specs from Kingston website for stock settings, and HW64info.exe on my PC right now showing me my settings. My Sager 13900HX-RTX 4090 laptop did this automatically without me having to go into the BIOS after installing. Upon booting it will read 64 GB dual rank and clock down to 5200mhz with better latency about 20-30 seconds longer than an normal boot time when identifying the new ram. If you want 5600mhz speed you must stick to 32GB (2x16). I can tell a difference gaming at 4k by 3-7 fps depending on the game versus the stock crucial 4800MHz CAS latency 46 memory that came with my laptop. Having 64 GB ram keeps my system from crashing when playing heavily modded lists like "Nolvus" Skyrim which regularly uses 35-37GB just for the game(42-43gb total with windows) while my RTX 4090 uses about 14.5-15GB VRAM. I can tell a difference when transferring large files and downloading large files with 64GB. It will Cache much more RAM doing these things. My paging file only "needs" to be 2gb according to windows when I use 64gb ram, but I still keep it at 10GB on my storage SSD. I think 64 GB is worth it if you game and do multi-core stuff with large file transfers and heavy decompression zip files et cetera. It is a worthy upgrade. I paid $220 for this about 2 years ago, and now it's only $169.99, and it is totally worth it.

I have a Dell Inspiron 16 plus (model 7640). It came with 16GB DDR5. I used this 64GB upgrade and so far is great!! One thing to note: When you put it in and first power up.... Give the system a couple minutes!!! (I guess the change is detected, then it does some initial checking to see what and how much is there compared to before). After you see the Dell logo, you can go into the BIOS, or diagnostics and check it out or test it to see if it is all good. Mine tested 100% perfect! Windows 11 pro also saw it all and uses it. I see a HUGE boost in running multiple apps at once (including A.I. Models). So yeah. Tested and good to go with Dell Inspiron 16 model 7640.

Awesome ram , plug and play no issues at all. Works perfectly.

Works perfectly and had 0 issues installing it myself.

Easy installation following youtube videos (I did disconnect the battery plug). Pry open should be carefully done. On Idle memory jumps between frequencies (see pictures), must be common for energy saving feature. I bought the pc with 16gb and before first turn on, I changed to 64gb. It prompts the message "memory has changed" and click continue for normal start-up. Bios version 1.9.0 from factory.

It's much quicker than the stock 4800 mhz RAM that came with my laptop, even though my laptop maxes out at 5200 mhz. I was attracted to this over the others because it has really good timings and latency when used PnP without the need for setting up XMP, which my laptop doesn't support. The hardware readings show it's working as expected.

Amazing kit, it works fast and everything were good after installation with my MSI BRAVO 15 C7VE no blue screen.

Upgraded a g16 to 32 gbs, quick and clean
