Arrived right, it took 20 days, more to blame for the delay in Curitiba! But it worked on my good R7 5700u, whoever has this model buys that is successful, was afraid due to several people saying it was incompatible, It all worked out.

The only negative is the long delivery. Went for almost a month. But it's worth it. Drove through diagnostics with windows: the operative is completely working and, most importantly, without memory errors. The seller is responsive. Below are provided screenshots with evidence of the performance of the two dies. P.S.: In the first screen, the diagnosis is only for the first die, with the second is also OK, just a limit of 5 photos.

Ordered 2 Dies of 8 GB 2400MHz. Came a month in advance (although it counted earlier), but the main thing arrived (well, as usual, a long shipment from Hong Kong). The packaging was not opened, not crumpled. Inserted into the laptop Acer Nitro 5 an515-51 (MB for anyone), I saw everything. If something goes wrong, I will supplement the review, but for now 5 stars.

Ordered DDR3 8GB 1600 MHz. Everything is good, the parcel was tracked, the RAM is working, the laptop started immediately, now 12 GB. Asus X550C laptop flight is normal. Thank you.

It's great! The order arrived on time. Memory fit-now on my iMac late 2011 - 32 GB RAM

The order came very quickly. Thanks to the seller. Happy New Year!

The product arrived very quickly, but it's bad luck, my laptop refused to work with this memory. No dancing with tambourines helped. On the other, the bar did not start either, it seems not working. Contacted the seller, several days of correspondence, several videos... There were some hassle in one word. In the end the seller returned the money to me. Ask why five stars? Yes, because the seller is sociable, answers quickly, you can negotiate compromises with him... This can happen to anyone, but not anyone can solve the issue correctly, honestly and quickly... It is for this five points. I will continue to place orders... P.S.-for example, at the same time with this order, I made an order at a sale in the sharashoffice "yzsh store"-I was washed with promises for 12 days, and as a result they merged with the order, and the goods became more expensive, and I without a processor and even messages from me stopped reading .... So there is something to compare with. For me, so the seller who does not throw or hide is trustworthy in the future.

Memory was delivered to the five checkpoint. Installed in an old laptop, now running right. Thank you.

8 GB memory, I am satisfied, the note is flying

Arrived exactly that day, as promised! at work I did not check how I will check the review.
