Review: Reliable and Efficient Performance Boost with Easy Installation - The Hynix 8GB PC4-21300 DDR4-2666MHz SODIMM module is an excellent upgrade for laptops needing a performance boost. With a 2666MHz speed and 1.2V low power consumption, it offers a perfect balance between efficiency and performance. Installing this single-rank memory module is straightforward, and the immediate improvement in multitasking and responsiveness is noticeable. Whether you’re using it for general productivity or light gaming, this module delivers smooth performance without any hiccups. Hynix is known for reliability, and this module is no exception—it's a dependable choice for users seeking a solid, affordable memory upgrade. Highly recommended!
Review: Product as described and working as expected - The product arrived on time, and is working as described; its running at 2400 MHz and not 2666 MHz (because my system supports RAM speeds up to 2400 MHz only). This perfectly matches the stick I already have, so both are now running in dual channel mode. I'm happy to see that my SSD's page file usage has shrunk to around 300 MB from 2/3GBs. Would definitely recommend this seller and the product.

## Questions & Answers

**Q: Is this one dimm or two?  two are pictured.**
A: The listing is for 8GB single stick of RAM.  Don't know why the picture shows two sticks.  Different picture than when I bought mine.

I would contact the seller just in case though.  Would not want to receive (2) 4GB sticks instead.

**Q: Do you ship to singapore?**
A: We do if you pay the DHL shipping cost

**Q: I have sk hynix 8gb 1rx8 pc4 2666v sa1 11 hma81gs6afr8n vk no ac, I ordered this/got 8gb 1rx8 pc4 2666v sa1 11 hma81gs6cjr8n vk no ad will this work?**
A: Yes.  They are the same.  Just from a different batch.

**Q: Does hma81gs6jjr8n-vk is the same as hma81gs6cjr8n-vk?**
A: What do you mean by 200mhz difference. This is what I have in my Dell laptop (jj not cj) and when I pull the serial # and run it, it comes up as DDR4 SODIMM 2666mhz. I want to double my RAM and use dual channel. So what's the difference? And does that mean dual channel won't work?
