Here’s a solid pick if you’re looking to upgrade your office workstation or server with reliable memory. This is a used SK Hynix 16GB DDR4 module running at 2400MHz (that’s PC4-19200). It’s an ECC UDIMM – error-correcting and unbuffered – which is perfect for systems that support ECC memory (common in Dell, HP, Lenovo, and Acer business desktops and some servers). The seller confirms it’s an original SK Hynix RAM stick, not a copy or clone. It’s been fully tested and is working 100%. Just a heads-up: this is ECC memory, but it’s NOT registered (unbuffered), so make sure your motherboard supports ECC UDIMMs. The model number is HMA82GU7AFR8N-UH, organized as 2Rx8. Great for a memory upgrade if your system is compatible, and you’re after that extra bit of stability ECC provides. If you’re dealing with data-heavy tasks or just want that peace of mind, this is a trustworthy module. Works in systems that take DDR4-2400 ECC UDIMMs. Check your PC or server specs to confirm compatibility before grabbing it. Seller notes it’s in good condition, tested, and ready to go. No fancy packaging, just the RAM as described. Ideal for a straightforward upgrade without breaking the bank on brand-new server RAM.
