I'm trying to build an 8 gpu single rig with vega 56 cards.
While waiting for the cards to arrive, do you think I will be able to enable HBCC on all of them ? Is it only a memory issue or a driver problem?
reading all the topic from the beggining, noone managed to make all hbcc enabled... i'm on progress with 2x rigs with 4x (each) 56's on tb-250 btc biostar mobos...maybe in the future if me or someone else find a solution i'll stick 2x more on each.. but so far it's a no brainer (not) cheap solution for very very good XMR hashrates
That was exactly my thought process when I built my 2 rigs running 4x64 Vega each. If you have some 2x8GB DDR3 RAM lying around in other computers like me, it turns out much cheaper. I can live with 8GB on my main PC until my mining machines can finance an upgrade and my summer home PC can live with a pair of 2GB sticks until summer. I am using ASRock H81 BTC R 2.0s. This way, the increased hashrate will pay for the second system in 2-4 months, less if you already own some components.
