Crucial Ballistix Sport LT BLS2K4G4S240FSD 2400 MHz, DDR4, DRAM, Laptop Gaming Memory Kit, 8GB (4GBx2), CL16 (Grey)

While the RAM still works and has low latency (CL16), it's not 2666MHz. Despite both Amazon and the packaging claiming that it is. It's got a price premium over the other RAM available at the moment and it's really not worth it. Just go for the cheapest you can find. You won't see it since it's inside a laptop so it does not matter if it looks nicer. And the performance gain (if any) would be minimal. You're talking like less than 1%.I returned this and bought the cheaper Crucial RAM instead. It has slightly higher latency (CL19) but it actually runs at the advertised 2666MHz speed.

A little disappointed with this product.On paper specs are wonderful and price competitive.Unfortunately this RAM supports the top speed (2666) just with XMP profile while JEDEC is tighten at 2400.On the bright side, CL16 is supported also at 2400.Thus check twice if your laptop supports XMP before buying this module: on my Asus TUF FX-504 there's no option to enable it in BIOS.

Bought this to upgrade from 8GB to 32GB.The RAM is doing a good job so far however my low review is due to the advertizing of the product. As it is said to be running up to 2,666Mhz which is what I was looking for, I have checked after installing the RAM and it only runs 2,400Mhz (standard speed). On some laptops you are able to change the XMP profile and have them run at full speed instead of the standard 2,400 unfortunately mine is not able to do that and I end up with a 2,400Mhz 32GB kit when I was thinking I was buying a 2,666Mhz kit.The description is misleading and this is a disappointment but other than that the RAM is ok.

If you have a DELL XPS 9560 this RAM is perfect. After installation just be sure to leave it turned on for 30 seconds - it looks like it will not boot. Eventually it will and comes up with a blue BIOS screen saying the meory has changed. Just click on [continue] and it will boot into Windows just fine and never ask that question again.

Excellent. Crucial (Micron) memory is always good and this, from their Ballistix range, is no exception.

After installing it, my laptop began to crash unexpectedly all the time, so I just removed it and put aside for a while; I thought it was incompatible with my Dell G5 laptop. I looked into the dell website and it seems that it is compatible, and my unit is just faulty.

Picked this up on a black Friday deal at the same price as the standard ram. Slightly less latency which makes for a sharper response. Fitted as an upgrade in a single-slot laptop from 8gb up to 16. Immediately notice that the fan runs less, and I'm not maxing out memory any more. Great buy of you're on the fence.

Shame the product is not the same as ordered on the web page and package it was sent in.Ordered 16 GB DDR4 2666 to match the current 4 GB DDR4 2666 already installed.Added it to the system, now i have 20 GB but at a reduced speed of DDR4-2400Confirmed with CPU-Z under Win 10 home 1909 build
