I have an extra x399d8a-2t new in box. 256GB ram desktop motherboard.
I bought the last 2 on amazon a while back but plotting is getting faster and I don’t need 2 builds.
Still has warranty from AsROCK/amazon.
My best experiences: Using chia farmer it Makes 3 k36 in parallel in 3 days with several SSD Rocket Plus raids, 128gb ram, & Threadripper 2970wx.
Plotting on nossd.com : 375TB made 4300 Level 5 compression plots in 3 weeks - with no SSDs just a 84 disk JBOD and 128G ram.
Should be able to utilize 512gb ram. I have not tested 512gb.
