How do you adjust the power limit as a percentage, I'm using simple mining os and the only power limit options I have myself are the actual wattage draw. Do I just run these at maximum and then backwardsly work out the percentage ?
QuintLeo broke the wattage down in another 1070ti thread,
https://bitcointalk.org/index.php?topic=2324651.20
Got a suprise this morning - my EVGA SC 1070 ti was on my doorstep when I wasn't expecting it 'till Monday.
I had already installed the latest 388.13 drivers on my Win7 single-slot "test rig" machine while doing some testing on a new 1080 ti earlier this week, so the test rig was ready to go.
I HAVE noticed some sluggishness on this machine, but it's a low-end Athlon 5050E dual core with 2 GB of ram so that's not unusual on it (machine was a LOT snappier on XP back in the day).
Testing on this rig was done in an A/C environment at 80F give or take a degree.
First thing I notice - the memory clock is WAY LOW, 7600 base clock for some reason. Due to that, this is the first EVGA card I can crank up to "+700" memory in Afterburner and actually have it work - as that's only 9000 actual EFFECTIVE memory clock.
Boost is NOT limited to the "factory spec" numbers - it's like any other 1070/1080/1080ti it'll boost as high as the power settings and temp let it.
Default TDP is 180 watts, same as a base 1080 or some higher-TDP 1070 models.
Another odd thing - Afterburner will let me OVERVOLT the card, but it won't let me UNDERVOLT it at all.
Did some testing on a copy of Genoil I had left over on that machine from ETH mining days - meh, pretty much the same as a 1070, obviously ETH is seriously memory limited on this card (not unexpected given other widespread reporting).
Moved to ZEC testing with EBWF.
Testing methodology - make a change in Afterburner, wait *at least* 2 rounds of EWBF stats posted, THEN average the next 3 stat rounds for the posted numbers.
At stock settings (except for using my "standard" Afterburner fan profile):
Hashrate settles in at about 467 sol/s with VERY little variation with the wattage figure in EWBF bouncing between 168 and 180 watts most of the time for an efficiency around 2.6-2.7 range.
Core is boosting to 1848 Mhz pretty much as a straight line, 62-63C at 64-66% fan.
Memory rock solid at "3798" (effective 7596).
Crank the memory up to +700 in Afterburner no other changes:
Hashrate settles in around 525 sol/s with noticeable variation, power however is pretty solid at 180 watts for efficiency at a little over 2.9
Core is boosting to between 1810 and 1823 with a lot of bounce between those figures, temp 64C at 68% fan.
Memory is rock solid at "4498" (effective 8996) and STAYS that way in the rest of the "+700 memory" testing.
Dial in +200 core clock in Afterburner:
Hashrate settles in to about 538 sol/s with some variation, power pretty solid at 180, efficiency a bit over 3.
Core is bouncing some, mostly 1987 with lows down to 1967 and occasional bounces up to 2000. I forgot to check temps, think they bounced up to 65C at 70% fan or so.
Drop TDP to 90% in Afterburner:
Hashrate at 540 sol/s and pretty SOLID, power solid at 161 watts for efficiency at 3.38 - and yes, the average hashrate DID GO UP A HAIR vs 100% TDP.
Core is bouncing 1911 and 1924 with an occasional 1898 or 1937, temp drops to 63C at 66% fan
Drop TDP to 80% in Afterburner:
Hashrate finally drops to 529 sol/s pretty solid, power pretty solid at 146, efficiency pretty solid at 3.64
Core bouncing a lot, 1810 to 1873 range, Temp to 60C at 60% fan.
Drop TDP to 70% in Afterburner:
Hashrate to 509 sol/s but bouncing some, power pretty solid at 126 watts for efficiency of appx 3.96 with one reading above 4 (517 sol/s)
Core bouncing in the 1709 to 1759 range, temp 56C at 52% fan.
Drop TDP to 60% in Afterburner (WATCH THESE FIGURES):
Hashrate 457 sol/s pretty stable, 103 solid watts, 4.46 efficiency.
Core bouncing in the 1557 to 1607 range, temp 54C at 48% fan.
This would be a VERY NICE setting to run a quiet multi-card rig in your BEDROOM, I have to put my head less than 2 feet from the GPU fans to hear them AT ALL.
This is also THE highest efficiency figure I've seen to date out of ANY card I've owned, and I don't remember seeing a better figure reported (though I might have missed or forgotten a slightly better reported figure somewhere).
Drop TDP to 50% in Afterburner:
Core clock drops to under 1200 and the hashrate drops so far the efficiency gets WORSE. Don't go this low on this card.

Memory
700,700,700,700,700,700,700,700,700
Power Limit
136,136,136,136,136,136,136,136,136 with everything mining away, no monitor or keyboard / mouse attached, I am drawing 1,365 Watts at the wall,
