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. ## Features - Lightweight ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07JP4C1PD | | Are Batteries Included | No | | Best Sellers Rank | #24,056 in Computers & Accessories ( See Top 100 in Computers & Accessories ) #236 in Memory | | Brand | SK Hynix | | Computer Memory Type | DDR4 SDRAM | | Country of Origin | China | | Customer Reviews | 4.0 4.0 out of 5 stars (913) | | Date First Available | 6 November 2018 | | Form Factor | SO-DIMM | | Item Weight | 18 g | | Item model number | 8541594395 | | Manufacturer | hp | | Memory Technology | DDR4 | | RAM Size | 8 GB | | Voltage | 1.2 Volts | ## Product Details - **Brand:** SK Hynix - **Compatible Devices:** Laptop - **Computer Memory Size:** 8 GB - **Memory Speed:** 2666 MHz - **RAM Memory Technology:** DDR4 ## Images ![Hynix 8GB PC4-21300 DDR4-2666MHz 260-Pin SODIMM 1.2V Single Rank Memory Module HMA81GS6CJR8N-VK - Image 1](https://m.media-amazon.com/images/I/31yxGJxpJnL.jpg) ![Hynix 8GB PC4-21300 DDR4-2666MHz 260-Pin SODIMM 1.2V Single Rank Memory Module HMA81GS6CJR8N-VK - Image 2](https://m.media-amazon.com/images/I/518RGd-JHHL.jpg) ## 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? ## Customer Reviews ### ⭐⭐⭐⭐⭐ Reliable and Efficient Performance Boost with Easy Installation *by S***L on 2 October 2024* The Hynix 8GB PC4-21300 DDR4-2666MHz SODIMM module is an excellent upgrade for laptops needing a performance boost.
