💡 How to pick memory
What to look for:
  • Must match your motherboard type (DDR4 or DDR5)
  • 16GB minimum for gaming, 32GB for content creation
  • Higher speed (MT/s) = better performance, especially for AMD
💰 Look for kits in 2 sticks (e.g. 2x8GB, 2x16GB) for dual-channel performance

★★★★★Very Happy
Product arrived on time, installed easily in my Alienware R7 desktop alongside the two 8 gig oem dimms and booted up immediately. Now I have 32 gigs running Linux and Windows 10 in a VM.

★★★★★Work perfectly.
Bought these to use for some work stations and eventually moved the hardware to a pc using an atx board and 8th gen i5. Perfectly compatible.

★★★★★Works as advertised. Easy to install. Slightly overpriced.
I was somewhat hesitant buying OEM memory modules on Amazon since I had seen videos on YouTube about buyers getting scammed and things like that. However, I was pleasantly surprised by my purchase. I had no issues installing the RAM, the RAM runs at its advertised speed (2667mhz), and it seems to work perfectly. Though, it is a bit overpriced for what it is. On a side note, this provides a HUGE performance boost for my PC since I went from 1 stick of 8GB running in single channel to 2 sticks of 8GB (16GB total) running in dual channel! If your motherboard supports it, I recommend going for a faster memory speed (3200mhz). If it cannot, or if you are not sure, then this will work perfectly. It was an exact match for the stick my pre-built PC already had.
