Re: AMD Mem Tweak - Read/modify mem timings on the fly - [Vega Friendly] [Win/Linux]
Eliovp, great work on this tool. Here are some of my results:
OS: linux/Ubuntu 18.04
miner: teamredminer 0.4.3
card: Vega 64 air cooled (MSI air boost OC w/ samsung mem)
core clock: ~1150Mhz
mem clock: 1100Mhz
timings modified: --rp 10 --rc 44 --rfc 300 --rrd 3 --rcdrd 12 --rcdwr 5
hashrate w/ stock timings: ~19.5kh/s
hashrate w/ new timings: 21.36kh/s
Unfortunately I don't have power readings from this rig, so I'm not sure how much the power usage increased with the new timings.
I think the card can be pushed more, but I don't have the time to keep tuning at the moment.

Holy OMG !!!!!!
I dont understand the various parameters, but i just followed todxx timings on my vega 64(air cooled/samsung).
Results:
Miner : SRBMiner 1.8.3
Algo : Cryptonight litev7
Clocks : 1408/1107/875 (ODT)
Actual : 1354/1107/850 (HWinfo)
Stock Timing : 4530 h/s
Todxx Timing : 4800 h/s
Thx Eliovp for the tool and todxx for making it way easier.
Will keep posting the magic as i try more algorithms
Is that working stable for anybody?
that rcdwr is very low. GPU crashes in a few minutes for me.
