Hynix 4GB PC4-19200 DDR4-2400MHz Non-ECC Unbuffered CL17 260-Pin SoDimm Memory Module Mfr P/N HMA851S6AFR6N-UH

Perfectly matching the spec for my Aspire 5 A515-46-R14K laptop's 4GB soldered RAM. Added this for optimized performance. In the Amazon's description page here it mentioned something about refurbished product but not appeared on the main descriptions, and I thought I probably ordered refurbished RAM by mistake. The product arrived in sealed bag and everything appeared new with no signs of being used before. As of now, I still cannot tell whether I got refurbished product. Working great!

Worked well for increasing the RAM on my HP laptop from 4GB to now a total of 8GB. Noticing significant better performance on the laptop. Make sure to check your laptop model, to ensure the RAM is compatible with your unit.

Perfecto

Perfect fit.

I added this to an Acer E5-575 series laptop. As described by Acer reviews and many you toob videos, its easy to service and upgrade. This memory module was plug and play, trouble free. After install, Win10 delayed after turn on as it recognized the memory and reconfigured itself, the boot screen was up < 1 minute, and took about 3 minutes before it was noticeably faster and smooth.

Before i got this ram stick I couldn't play rust and cod at a consistent 60 frames i added this and it helped with so much processing issues. i had only 8 gigs before. its probably the best ram you could get right now for this price. The package also came way faster than the estimated time setup: Ryzen 5 3550h GTX 1050 12 gb 2400 mhz ram

Works great with ACER Aspire E15. I have the Amazon best selling, budget E5-575-33BM model, and it just works without glitch. The Aspire E15 was designed such that you can easily upgrade HDD, RAM, just undo 3 screws and you're in. Took me less than 10min to do upgrade. Great product & great price.

Installed this into my computer and works as intended.

Installed on my asus a541uv laptop. Now it's having total of 8GB RAM (4*2) running in dual channel mode. The performance improved a lot.

Perfecta opción para la ampliación de mi portátil

Works on HP 15 bs 541TU.

Ram is working fine with my Dell Inspiron15 3567. Yogi seller is very supportive but I didn't get a Hynix ram module. I got a Samsung 4gb ram stick which is also working perfectly with my old Hynix 4gb ram module. I bought it last month in 2850 rupee. A little expensive but it's worth it. Note, First time users must be careful while installing it. See installation videos on Youtube if needed or let a professional do that for you. Before order make sure specifications must be matched with your old Ram stick if you are going to use it with that. You can check that with CPU-Z software. Remember 32bit os will support upto 4gb ram only. Anyway, My laptop's gaming performance has increased by 30-40%, not a huge impact but noticable. I'm happy with this product. Hope it lasts longer. Will update review time to time. Thanks for your time! Update13 July 2021: Two years almost complete, Ram is working fine.

Stopped working within 3 months of use. No replacement. No warranty.
