2.1.1 - VirtualAlloc failed / Fatal Error Plotting - Plotting Advice Please

Hi Folks,

I seem to be having to reboot the box every night at the moment once I receive this error below starting off plots. Once I reboot it works again.

Anyone got any ideas how to resolve this without a reboot or better still, to stop it all together ?

Error output below.

Thanks!

Its a well known error, but doesn’t normally affect 3090’s, it normally affects the old Pascal cards, like the P4 and 10 series, and more often farming rather than plotting. I’ve no idea whay its affecting you, perhaps ask on the Chia Discord channel.

Personally when GH 2 launched I went with that, no problems, lots more plots for the raw space, which mean more income that far outweighs the dev fee.
