SK hynix HMA851S6CJR6N - VK Non ECC PC4-2666V 4GB DDR4 at 2666MHz 260pin SDRAM SODIMM Single Kit Laptop Memory - OEM

Good product

The product does not have a proper packaging. It comes in a ziplock cover. So it is hard to know if it is a used item or new

Worked in my iMac, well packaged, installed in iMac 2019 , no problems worked first try.

Problem statement: my computer started lagging after a mandatory Windows 10 “upgrade”. I couldn’t open several programs at once and my computer would crash at random. I assumed it was a RAM issue so I opted to buy a stick since I had an open slot. As some other reviewers mentioned, this is the same brand that came stock in my HP laptop (Elitebook), so I was comforted by this and the fact that this was the cheapest option per GB: Win/win It was easy to install and when I restarted my laptop it recognized the new hardware immediately and when I checked in device manager the new memory appeared in the total RAM. (A friendly reminder, don’t over tighten the screws upon reattaching the laptop cover, those little screws are easily stripped...) Also, to answer one of the questions above from a user: laptop RAM is different in physical size/shape than your typical desktop CPU RAM so make sure you buy the correct item. If you are adding Additional RAM, the best way to find out what you need is to see what you already have in your computer. The two side by side RAM slots will accept the same size/shape RAM memory stick. Even though you may be planning on purchasing 8gb and already have a 4gb stick installed, those two sticks of memory are going to be the same physical size. I wouldn’t buy RAM without getting a visual on 1) how many available slots I have; 2)what the actual existing RAM configuration is. For example, in my last computer I thought since I had 8Gb of RAM that I had an available slot for another 8gb. I was lazy and didn’t bother opening the machine prior to ordering, only to find out that I already had two sticks of 4gb (not one 8gb) and I had to remove one 4gb stick to use the new 8gb stick, resulting in 12gb of RAM instead of the 16gb I was hoping for. to sum up my product experience: Great value and certainly worth the 5 minutes it took to install and reboot.

Il prodotto funziona perfettamente

Lieferung und die Ware in Ordnung

La barrette est bien reconnue sur un portable HP 15-bw035nf, 8Go de RAM maximum sur cette machine, seule contrainte pour l'ajout il faut le démonter (voir tutos sur le net).
