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

The memory was detected immediately and is running very well after upgrading from 4 to 8 gigs on a laptop purchased used on ebay. Very low price.

This was an easy upgrade for my HP 14-df0023cl laptop which only had 4 GB of RAM. This 4 GB SD RAM module is identical to the one supplied by HP. Works perfectly and now it has 8GB. Noticeably faster when I have a lot of programs open. Fast delivery too. +++

The seller was fantastic! The product arrived quicky and well-packaged. Everything was exactly as described, and the quality exceeded my expectation! Thanks

I recently bought a cheap HP laptop that only came with 4 GB of RAM but had a an open RAM slot available. I knew going in that I would upgrade the RAM immediately. This RAM stick was actually identical to the one that came preinstalled in the HP machine. Same manufacturer and same model #. I popped it in and to the open slot and BIOS and Windows recognized immediately. No issues. For the price it is hard to beat if you are upgrading from 4 GB to 8 GB on a laptop with an open DIMM slot. A lot of OEMs are going to be using this exact stick.HP model this went into is Model: 14-DK1003DX for anyone looking to upgrade the same machine.

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/winIt 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.

Just received the memory, came in a box labeled "Certified Refurbished". I was not expecting that. No where on this item that I saw does it say the product is not new. It should clearly be labeled refurbished if it is not.Not worth attempting a return assuming it works, but not exactly what I was expecting.Update: Memory tested out successful - so appears good - will update if it fails, but changing my initial rating from 3 to 4.

Era la que buscaba para potenciar un PC que tenía otra igual
