Re: [ANN] TeamRedMiner 0.4.3 - Cryptonight Thread

8 nitros 64 pulling only 1112W at the wall is mighty impressive!! I think you might be the only person being able to pull that off

The problem with my rig is none of my Vega64 nor Vega56 cards is able to run at 1200/1100/<880mv/L28+28(L24+24) without crashing. Same goes for CNr algo. Can't go below 870mV. So, I am really baffled how you are able to pull off that power draw. Wonder if temperature have a role in the stability that you are getting with that extreme undervolt. It's hot where I live and my GPU temp is 65C.

The 850 cclock and cn_config=L18+18 are key. IIRC, for the same exact voltage setting, I saw a 15w difference in power consumption just increasing cn_config to L28+28.

I also had a ton of trouble trying to find stable settings for the 1950 h/s range - at the end of the day, the time spent hunting for stable settings, plus the extra power required, just weren't worth the extra 1kh/s.

That being said, if you can't get < 880mv, you likely have a problem somewhere else, possibly your ppt - try disabling all other states, or make sure you don't have out-of-order voltages (since 19.x, many people are forgoing ppts, which is a mistake given that you still can't change the mem-p2 voltage setting.) And while higher temps do require more power, it's also all the more reason to get your voltage down...

When you say 850 cclock do you mean effective or setting in overdriventool?
850 in overdriventool is closer to 800 effective and that'd be super low...
Would L18+18 work for flashed 56's just as well?

i'm using core-p0, so ACG is disabled -- I only see a droop to 849 effective vs 852 setting.

My flashed 56 likes L22+22 best.

I had to set my p0 cclock a little higher (900) or else a GPU would drop... but with L22+22, 825mV on 4 Vegas and 850mV on the two weaker cards, I'm now hashing at just under 16 kh/s per card, so approx 95 kh/s for the rig at a power draw at the wall of 875W (which is indeed ~135W per GPU). That's close to 110 h/W. Pretty amazing in itw own right, but still far from your 18.5 kh/s. Not sure how you manage to get these hashrates at these voltages...
