Hey everyone,
New here, just set up a 6GPU 6700XT rig. Anyone care to share their core, mem clocks, voltage, power limit and fan command line settings to lower the power and optimize the hashrates? Would be much appreciated, thanks.
Hi, wht chipset you on and flavour of os?
Running here Asus B550 gaming with Ryzen 5600 16gb DDR4 3200, bit ott for a rig but first new mobo in years was overdue nicely loaded with 5 x RX6800XT running cool n stable. adding 6th later tonight along with extra PSU and balance the load out as the current single cheap 2000W psu has v aggresive cooling fan that is putting out more noise than the GPU fans proper at present and it is not satisfactory but beasts these cards be.
Only managed so far to get Manjaro working for multiple GPU and have high stale rate also note but still testing that some cards dont mind a mclock setting but others throw a wobble with current drivers but the key i have found is below and right now no mclock is ok but would like to boost it up to 1075 to get the 64Mh that they will do but as things are stable and running ok for now heating the house now its gone chilly as testing continues lol
