I've been buying used memory for my various Dell workstations for 15 years and I have never had a problem with Hynex, which is often the stock brand in my Dells. I tend to buy the maximum size and speed for the motherboard long after the prices come down and newer faster stuff is available for newer faster systems. This seems to weed out unreliable used memory, as I have never ever had a problem with installing a used set of the CORRECT SPECIFICATION memory that is compatible with many different brands of computer. This means that if I am buying Hynix, I am matching other memory already already installed or I am replacing all of the old RAM with uniformity. I have mixed and matched other brands or capacities and or speed, but that is only as good as the weakest link or slowest module, and is not as reliable as always matching pairs, if possible, with identical specs, per each pair, at least, when you have more than one. So, if you just look at the one you've got installed and match the specs, the motherboard will be happy with the matched pair. If you've already have a pair, and are filling two more slots, be sure the new pair match each other, even if they differ from the other pair. The board runs as fast as the slowest pair, so uniformity is always optimum for even performance, in general. Hynix seems to work fine with slower or older RAM, within the recommended specification, ( e.g. PC3-12800 ) Read full review

1 ram stick worked in all devices. The 2nd ram stick would only run in 2 of 6 laptops. I had to shuffle ram sticks around but finally found a home for it.

I checked out quite a few 4GB memory modules as I wanted to upgrade my computer and I was worried about a possible mismatch with the memory already installed. I selected this particular module as the ID number was virtually identical to the module already installed. Once I installed the additional module, I started the computer and let the BIOS figure out that something had changed and everything worked as hoped. When I checked the system status, it indicated that I now had 8GB. Perfect!

adding additional memory to a system is a win-win; it's a good idea to max out your motherboard memory slots when running Win 10 [64 bit] - overall I have 16 GB that makes the system run like a champ. buying thru eBay makes it easy to match the memory that you already have.

Excellent price, excellent product, very good transfer speed, when installed on your laptop, is getting longer battery life, and the system works faster.
