Rasalas 8GB (2X 4GB) PC3L-12800S DDR3L 1600MHz 4GB RAM DDR3L PC3L-12800S 1600MHZ SODIMM 2Rx8 1.35V 204Pin CL11 Memory kit for Laptop/Notebook/AIO Computer Upgrade

I have been refurbishing a number of elderly HP EliteBook 840 G1 laptops recently. Mostly destined for friends and family, I have upgraded the SSD, added a new CMOS battery, checked the main battery and added more memory. Usually, I have installed 8GB of DDR3 RAM which has proved more than adequate.However, the last (and best condition) EliteBook is for me! So, I decided to give it a decent start in its new life. As such, I added a spare Samsung 1TB EVO SSD and this very reasonably priced 16GB memory kit.The memory is in 2 x 8GB sticks and they slotted straight in without any issues. I checked all was OK in BIOS and then booted the laptop - it runs so smoothly without the slightest hiccup - just like having a new PC. So, I am very pleased and just have to keep the laptop out of my daughter's sticky hands.....NOTE. In the seller's listing, I noted there are 2 apparently identically specified 16GB (2 x 8GB) kits - 'Blue' and 'Green'. The green variant being £1 more expensive. I was concerned there may be some important compatibility differences between the 2 offerings. However, the only differences I could see in the photos were the chipsets being from different manufacturers. Anyway, the blue variation was the cheaper and, as I said above, it works fine for me!Perhaps I have missed something?

I got these to speed up my laptop which is a refurbished HP Elitebook. Its very high spec with an i7 processor but limited by having only 4GB RAM. This kit takes it up to its max capacity of 16GB and its flying on stuff that would previously slow it down, like the time taken to open Fusion 360 (CAD programme) or MS Teams (which I hate- but an i7 processor and 16GB RAM makes it tolerable). Be aware though that the HP Elitebook has easy to open panels and hatches to get in to things like memory and drives, some clip-together laptops won't be so easy to install.

In customer questions it claims these are compatible with a mid 2012 13inch MacBook Pro. However, with 240 pin instead of 204 pin there are quite clearly not.

Purchasing DDR3 new, is almost pointless at this stage, however, I decided to do it a year ago for my old system. The speeds are nothing amazing, as it is DDR3 however, it still ran games fine while limited to the CPU that still supports DDR3 memory.If for any reason you need to have DDR3 memory, for the price this kit is good, and will get pretty much anything you need done.

Caused lots of memory errors on my machine which went away every time I removed it so my confidence in this product is very low. Sometimes you get what you pay for.
