llevo mas de 2 años usandolas y son perfectas, rapidas, compatibles, y economicas

Perfect fit and registered all 16gb in my Synology NAS. If you know anything about them, they are finicky about what hardware they will 'certify' as acceptable in their fragile ecosystems. Works perfectly. Likely overkill for my needs as I'm just using the NAS for storage and streaming of content through Plex.

I'm going to comment on something that I noticed with this DDR4 SODIMM, but please do not take this as the word of the manufacturer. This is just my own experience with the RAM module and it is not a promise that it will be the same with yours.

Before having this module installed, I had a different kit that was 3200 MHz. I had to manually set it in BIOS to 3200 MHz because XMP profile ws not available on that other module. Anyway, after installing this, I booted into Windows and was surprised to see that this one also runs at 3200 MHz with a CAS latency of 20. I didn't change anything in the BIOS while swapping the RAM, so the old profile of 3200 MHz was passed on to this one.

I was pleasantly surprised to see that it runs a 3200 MHz, because on the listing here it says that it is rated only for 2666 MHz. Rarely do I buy a piece of technology only to find out later that it works even better than the rated spec. This was a nice surprise.

I ran a few memory tests, and they all passed. No issues, no errors. Just perfect.

Again, I cannot promise that your experience will be the same. I am just sharing how it worked out for me.

Still working without any issues. Great product comes with good price.

32GB of RAM is probably FAR more than I'll ever need for gaming, but since I finally splurged on a gaming rig, even if it was a middle-of-the-road model, I wanted to have every possible thing supped up. The RAM was the last thing to cross off that list after SSD storage and boot drives.
The biggest issue with upgrading my RAM was one of compatibility. Not a lot of information existed for my particular model of computer, the new Dell G7 7590 (the 2019 edition). As this RAM uses XMP profiles, not every motherboard supports it. Also not helping matters was the fact that XMP options aren't listed in my system's BIOS (as far as I can tell), so theoretically it could work, but a lot of the information that did exist skewed toward it not working.
Thus, buying this was an expensive experiment. Before I get any further, I'll give my reasons for buying this particular RAM: it's made by Kingston, the manufacturer of the stock RAM that came with my computer (Dell uses RAM from many manufacturers, I think, so yours might differ) and I wanted it to be an upgrade in more than just capacity. That CAS latency of 15 looked pretty good to me (improvement from CL19).
Results: plug and play. Worked like a charm. My computer booted fine and recognized the increased capacity at the max bandwidth allowed by system (2667MHz). Screenshots provided from CPU-Z for reference. (note: I am running BIOS version 1.6, I don't know if this will work in the stock BIOS which I think is either 1.3 or 1.3.1)
Verdict: great upgrade and confirmed by this guy to work in a G7 7590. No issues to report as of yet, but I don't expect any.
