    Reviewed in the United States on October 15, 2019
    Verified Purchase
    Arrived fast, no damage or defects. It took me a while to install mine because I have an all in one desktop and it is a pain to flip over and hook back up each time I needed to test it. Advice for other complete novices: take your time fitting them into the banks and watch videos showing how they need to be seated esp if you have an all in one like I do. This will save you a lot of time. The only thing I would change about this product is how it was shipped; it was sent loose in a padded envelope and I’d prefer a small box but that’s a minor nag - it arrived completely intact and both sticks are working great.

    5.0 out of 5 stars Perfect for my iMac 27
    Reviewed in the United States on September 16, 2016
    Verified Purchase
    I put these into my late 2015 iMac 27 5K, one of the last Macs that allow the user to upgrade RAM. I think Apple's price to upgrade it from the factory is $100. Obviously, I spent a lot less with these.

    They went right in and worked. I now have 16GB of RAM in the iMac, which is sufficient to do almost anything. Also, when I switch to Boot Camp to run PC games, they work perfectly.

    If you have a newer iMac, these are perfect.

    iMac is a bit sloppier than it used to be, so seating the RAM might take 2 or 3 tries. (Just lower the clip back slowly while pushing the RAM in) I do have some weird lines at the top of the screen now when the mac wakes up, but these are gone when logging in. No other issues. This is perfect for a cheap upgrade.

    5.0 out of 5 stars Excellent RAM - runs faster than spec in both Dell Latitude e6430 and HP Elitebook 840 G2
    Reviewed in the United States on January 28, 2019
    Verified Purchase
    As stated - have used this kit to upgrade RAM in both boxes listed - both systems spec'd for 1600 MHz RAM and both now running (and stable) at 1867 MHz. BIOS, WIN 10 and CPU-Z all report RAM running at 1866/67 @ 1.35V. Both of these systems use on-board Intel Video and thus share system memory - the faster RAM reports an increase in video frame rates. No problems/instability noted after several weeks (both systems running WIN 10 PRO/64-bit on Crucial SSDs). Good stuff.

    Same specs as Synology RAM for less than half the price. Non-Synology RAM may void a warranty but this works fine in my DS418play. 8 GB (matched pair of 4GB sticks) is the max. amount of RAM useable by these units so don't waste your money on any more.

    Verified Purchase
    I put this pair of 4 GB sticks in a Synology DS218+. You have to disassemble essentially the entire NAS to get to the first DIMM slot, but it only took about 20 minutes total and the RAM is 100% compatible with this model. Great upgrade if you want to run Docker containers or do hardware transcoding with Plex on your Synology.

    Reviewed in Italy on October 11, 2019
    Verified Purchase
    Comprate per espandere a 8gb la ram del qnap ts-x53be con 2gb di fabbrica.
    Spedite da Amazon, sono arrivate con due giorni di anticipo rispetto alla data prevista.
    La confezione Crucial è un po' spartana, un singolo blister contenente entrambi i moduli da 4gb, ma assieme alla busta di cartone, sufficiente a proteggere il contenuto.
    Ho subito montato le ram sul nas e l'ho testata con memtest86, 4 ripetizioni canoniche, senza nessun errore.
    Prezzo nella media, non particolarmente basso, ma ram stabili e ben funzionanti nel qnap.
