BTW anyone recall if there's any limitations in GPU scaling? I popped a 2nd RTX 3080 into my one box doing distributed.net.
I was seeing about 180k to 186k blocks/day with one RTX 3080. Now with two I am seeing about 250k to 259k blocks/day. That said I super have not paid attention to clocks or temps or anything else, I literally had long enough to install the 2nd RTX 3080, make sure it booted, then ran off to do actual work-- so I will definitely check on things when I get a minute. There's plenty of space between the cards given the top card is only 2 slots.
FWIW the 2nd RTX 3080 is a Zotac LHR card with a blower, while the original card is an Asus GeForce RTX 3080 TUF Gaming V2. So maybe LHR cards are gimped in RC5-72?
