OLOy DDR5 RAM 32GB (2x16GB) Black Hairline Blade 6400 MHz CL32 1.35V Gaming UDIMM (MD5U1664320BRLDA) at Amazon.com

Crashes when XMP profile is enabled. Modules unable to reach the manufacturers advertised speeds.

Like another user said it defaulted to 2133 but I simply set it to 3000 in the bios with no issues has been running great ever since.

I was a little hesitant to buy these because of the brand. However, since I was buying from Amazon I knew I could return if they didn't work or work up to par. Installed and working as expected. My brother only plays games and does schoolwork on his PC and it runs fast with no problems. Can't speak for overclocking, etc.

I purchase 2 sticks of 16GB 3000Mhz RAM for $120. That is an exceptional deal. I haven't tried to OC then yet, but am interested to see how they perform. The heat sinks are sturdy and not flimsy. At some point RAM is RAM. There are only a few actual manufacturers of RAM so most of the time you are just paying extra for a brand name.
