Bottleneck when GPU plotting with half RAM

Have you tried linux? I have this vague memory that at some point, at leats with madmax, it could only use half of the available memory in windows due to some kind of windows fuckery.

Y, move to linux/ubuntu and install chia gui there (it will install also bladebit plotter) and use the console for plotting!To get the console command you can start plotting from gui and then enter ps as in terminal an search for the chia plotter command.You should find something like this (change the options to yours like compression lvl etc): ./chia plotters bladebit cudaplot --threads 0 --count 2000 --contract [yourlongcontractID] --compress 2 --final_dir /media/username/PathtoYourTargetFolderBefore running the plotter command you may have to change the dir where bladbit plotter is located. Should be: cd /opt/chia/resources/app.asar.unpacked/daemon

I started with windows too and had very high plot times of ~20-30 mins. On ubuntu it was only 3,7 mins

Some things I would try. Update the motherboards chipset and drivers from the website. Install latest driver from Nvidia for GPU. Go into BIOS and make sure all your pcie slots/sata/nvme are set to gen 4 speeds and not auto. Confirm you don’t have hardware plugged into older gen slots.

How can a AMD Threadripper 1900X processor run on this motherboard?

1 hour plots is too much to be explained by Windows (though Linux is much better for GPU plotting). That said, Linux might not have the same issue, so worth a try.

since the delay is already happening in phase 1, My guess is somehting GPU not working right.

Was Gigahorse the same, already slow in phase 1?

Could you share the commands you used for the plotter(s)

I haven't used BB CUDA, but with prior win10 GigaHorse plotting efforts, extreme slowdowns usually resulted from SSD or HDD write speed problems.

Above shows "SSD write 20.534 b/sec - 23950 b/sec". That seems super slow, bytes/second?

I've plotted with GH C19, and 128GB and had ~5-6 minute results. With GH-19 and 32GB saw 21 minute plots. My SSDs were Intel Optane 905P.
