POSTed and has two memory profiles. One at JDEC of 3000 and one at 3600 for XMP. Short heatsinks so it fits under Noctua NH-D15 coolers. Good price for the amount.

Won't run at CAS 17 on AMD systems. I tried on an X570 board with 5800X3D and on a B550 board with an 5900X and no dice. You can select XMP profile or manually set CAS to 17 and it always boots at 18. If you set it to 16 it will boot but it becomes unstable so it most likely needs more voltage to do that. I'm not overclocking the memory or else I would have bought different kit for that.

I've only ever had two memory kits in the past 25 years not run at advertised speeds. This is that second kit. Oh well. It runs fine at CAS 18, but I purchased it based on CAS 17 specs. CAS 18 memory is cheaper, but not that much cheaper to pull it out, do a return and swap memory kits. I know it's been a long time since I've had Kingston memory. Elpida was around and DDR2 was the hot stuff. But I had a set of Kingston RAM that didn't need heat spreaders because it needed very little voltage to run at its advertised speeds. Yeah, it looked boring, but what a champion kit for my workstation/gaming rig. Unfortunately, this is that not that kit a decade later. Just a bummer, is all. A long-winded tail of disappointment. I'll survive but with a bit of sadness.
