CMH32GX5M2D6000C36 Unsure about die that is used (going to assume Samsung b die just via timings) XMP3.0 36-36-36-76 1.35V aluminium heatsink
Spotted this on pcpartpicker. Usual MSRP is $359. Seemed like a decent 32GB kit with fast speeds and tight timings. Do note that if you are using Zen 4 that speeds past 6000mhz can be unstable.
Cheap DDR5 maybe? Sold by Amazon UK but may listing says may take 4 to 6 weeks to arrive.
