Re: AMD Mem Tweak - Read/modify mem timings on the fly

Hi!

For everyone testing modded mem timings for CN using TeamRedMiner:

TRM v0.4.4 is released on GitHub (https://github.com/todxx/teamredminer/releases).

The release contains a new *-mode specifically targeted towards Vega GPUs with modded mem timings and running normal CN variants (not Turtle). Its the new default mode for Vegas.

The release also contains a new tuning guide with recipes for Vegas. Using it we can produce seriously sexy hashrates on all Vegas without increasing core clock above 1407 MHz (CN/r: 2440 h/s V64, 2250 h/s V56@64, 2130 h/s 56 Hynix).

The release will be in alpha state for a few hours before we post in our Bitcointalk topic, if anyone has the chance to take it for a spin, please do so and let us know your CN/r results.

Cheers, K

Nice, from 1.75 to 2.03 kh/s increase for cn/r from 0.4.3 to 0.4.4. vega56 hynix 1200/940@775mv (gpu-z shown clocks and voltage) Same timings

How about power? How many watts?

I don't know, 98watt gpu power in gpu-z. The same as trtl with 0.4.3
config 16*16 doesn't work for my vegas64 and 19.4.1 drivers. 14*14 config is ok and I'm getting 2.33kh/s (1300/1090@825mv 120 watt gpu-z )

Should have been more clear reg the *-mode: turtle is fine with the old + mode. The new mode is for all 2MB pad variants.

For power: weve seen increased efficiency across the board. A rule of thumb has been +2x% hashrate increase for +x% power, one example was a Vega 64 with +15% hashrate and +7.8% power draw.
