- Highest Hashrate impact : lower RC (good cards : 44, lower cards 45) - too low leads to invalid shares
- RP has high impact on stabilty, but low impact on hashrate (preferred 12 as average for stability) -- too low leads to gpu crash withing minutes
- Second highest HR impact : lower RFC (248) - too low crashes cards
- Having RRDS and RRDL as same value helps in stability
- Better to leave CL unimpacted in my tests, it is pretty much linked to all values.
- There are some hidden param that are not exposed by the tool, so it is advised that if you are not gonna change a value, dont use that param to set the default value, ignore the parameter
- Normal memory overclock plays a huge part in this tuning. 1107mhz is the highest you can reach without breaking the SOC barrier. You must have a stable non invalid shares throwing OC b4 appling the timing.
- My 6 cards timing and OC:
- 1. 1107 : --rcdrd 12 --rcdwr 5 --rc 44 --rp 12 --rrds 3 --rrdl 3 --rfc 248 : Valid Shares : Highest OC, Timing
- 2. 1107 : --rcdrd 12 --rcdwr 5 --rc 44 --rp 12 --rrds 3 --rrdl 3 --rfc 248 : Valid Shares : Highest OC, Timing
- 3. 1050 : --rcdrd 12 --rcdwr 5 --rc 44 --rp 12 --rrds 3 --rrdl 3 --rfc 248 : Highest Timing, Invalid Shares if 1107 OC - 1 invalid per 10 mins
- 4. 1050 : --rcdrd 12 --rcdwr 5 --rc 44 --rp 12 --rrds 3 --rrdl 3 --rfc 248 : Highest Timing, Invalid Shares if 1107 OC - 1 invalid per 10 mins
- 5. 1107 : --rcdrd 12 --rcdwr 5 --rc 45 --rp 12 --rrds 3 --rrdl 3 --rfc 248 : Highest OC, Invalid Shares if --rc 44 - 1 invalid per 4 hours
- 6. 1107 : --rcdrd 12 --rcdwr 5 --rc 45 --rp 12 --rrds 3 --rrdl 3 --rfc 248 : Highest OC, Invalid Shares if --rc 44 - 1 invalid per 3 hours
My testing have been limited to only few params, yet to fully test the other params.
