💡 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

★★★★★Good Ram
Ram is over priced but it works perfectly for my build
Larry Wilson · 2026-03-19 · via amazon
★★★★★Perfect fit, well made and just works
I was a little skeptical, whether this would work in my 6 year old computer but it worked like a charm, very happy with this purchase. Perfect fit into the slot and comes with heat sinks!

★★★★★It works well.
Works as intended and minimalistic while being a decent price, I picked it up for 51$ which isn’t bad but I’m sure it will go up but for 51$ it’s worth recommending.

★★★★★Slow 2666mhz- check compatibility
This OLOy Black Owl DDR4 RAM was not compatible with the b550 I tried it on. I believe the reason was its speed . I returned it.

★★★★★Native 2666 MHz support without having to enable memory overclocking
I bought these after suffering a dead on arrival DIMM chip from a name brand memory manufacturer (see my other reviews to see which brand) to go with a new PC build (2020 Gigabyte motherboard, 2020 Intel processor). The name brand memory showed up in my Bios as 2400 MHz memory, I had to enable the memory overclocking function for the name-brand to show up and function as it was sold (2666 Mhz). I returned/replaced the name brand memory with this brand because of the dead DIMM chip. A) Both chips worked out of the box, unlike the name brand. B) I didn't have to enable any sort of overclocking in my bios for these to show up and function at the 2666 MHz they are listed as. And no I didn't just leave memory overclocking on... I shut it off before I removed the other chips. That other memory should be sold as "Can reach 2666 MHz with overclocking" - this OLOy memory is recognized and functions at 2666 MHz without overclocking enabled. A quality product at a reasonable price.
