My results:

1080Ti Watercooled

Stock settings: 4:10 per WU and 260W

Full overclock: 3:40 per WU and 350W

 

1080Ti 3 slot cooler:

Stock settings: 4:00 per WU and 250W

Full overclock: 3:30 per WU and 300W

 

I guess my Aorus watercooled card really lost silicon lottery...

Holy moly, what model is that other 1080Ti?

 

Hmmm, 3 slot cooler.  Is that a ZOTAC?

I had a 980Ti ZOTAC AMP that was a gold GPU (it OC to 1600MHz on stock BIOS on its air cooler).

 

So far what I manage with my FTW3 model:

 

Power limit of 70% with clocks at 1650-1683MHz.  It is doing WUs around 4:11-4:13 mark.

The OS is W10 LSTB 2016 with 436.15 Nvidia drivers. 

I know, the OS is quite due for an update.  But heck, it is still getting security updates.

No idea, I bought that other 1080Ti only for folding month... It came without box and it cost me 350 euro. I'll have to check tomorrow as it is in remote location near my ASICs.

I am not sure why and how, but threads=7 seem to work better than threads=8 for my 1080 Ti as it finishes WUs around 10-20 seconds faster.

Threads=6 however is same as threads=7, and as usual threads=9 crashes WUs instantly. And any less than threads=6 is BAD (timewise).

 

lut_size=16 is bad

lut_size=17 is better

lut_size=18 is best

lut_size=19 is awful

lut_size=20 do not even try this on 1080 Ti

 

sieve_size=25 destroys my ears due to coil whine and it is bad timewise

sieve_size=28 is good

sieve_size=29 is almost same as 30

sieve_size=30 is best

Anything above 30 is instant crash

 

Other settings do not seem to affect speed.

Hmmm, I have yet to try thread=7.  I may give that a go and see what times I get.  I am currently leaving my 1080Ti tune at 70% power limit since that keeps temps at around 60-62C and the times are not bad, 4:13-4:15.

If setting to thread=7 can push it back to 4:00 or lower, that would be sweet.

 

Next go is to see how app_config.xml settings will affect the next batch of WUs.  See how my default in that works and then next is to see how doing two WUs on a GPU pans out.

 

I do have second 1080Ti, a SC Black.  I can't seem to find the air cooler for it (took it off to do some, well, dremel work mod idea that I never finish  xD).  I do have a water block for that one, just need to get a loop setup to run it with the block on.

 

Edit:  Thread=7 made mine go up to 4:21 on WU time at 70% power limit.  Seems mine likes thread=8.

Nice, I’ll try what those settings do to my VII

This many months past the BOINC Pentathlon I've left my rigs running on a schedule. Now with the cold weather here I can let them whirl 24/7 and heat the house. I've really been enjoying World Community Grid. I like the idea of contributing to fighting disease.

Do you guys also OC the Memory on your cards or only the core?

i am not sure if memory would be beneficial because collatz is using verry little mem on my VII

I OC everything. Memory is always +200 on my 1080 Ti. Gaming/Folding/BOINC.

However, I do not think that it helps that much for Folding and BOINC.

For gaming I can push it to around +500/750 for less memory intense games and for Folding and BOINC, I think it worked fine even on +1000. So I just pulled it back to avoid crashes/artifacts and it is a fine clock overall.

Ok interesting... as soon as I OC my mem on the VII (even +50mhz) Core clocks go way down and I am loosing considerable amounts of time/WU.

therefore I’ll stick with 2,1G on core and leave mem stock

Well, AMD is not same as Nvidia, and Memory OC for AMD helps in Folding as far as I know. But I am not sure for BOINC.

Also, I have only used AMD GPUs that are from GCN 1.0 architecture up to GCN 1.3. I've never had experience with GCN 1.4 (Vega and above).

Yes while folding I am eunning mich more mem than core OC

 

soon I’ll get my hands on a RX5700xt

eager to find out how that performs in BOINC (currently doesn’t work in F@H :/) 

[Favebook]

Also, looks like I found a sweet spot for my 1080 Ti while crunching on collatz

 

Adding every 20% of Power Limit, adds about 50W to power usage.

1. 150 PL - 360W PU - WUs of 3:40

2. 110 PL - 275W PU - WUs of 3:55

2. 100 PL - 250W PU - WUs of 4:00

3. 95 PL - 230W PU - WUs of 4:05

3. 90 PL - 220W PU - WUs of 4:10

3. 85 PL - 210W PU - WUs of 4:15

4. 80 PL - 200W PU - WUs of 4:20

5. 75 PL - 190 W PU - WUs of 4:30

Nice job!

i am currently still figuring out how much I can push without doing Igors more power mod (I know the card can handle it, but I don’t want a 1kW PC) and now I am sitting at ~3:45 per WU. I’ll see if that’s stable and tomorrow I’ll try to dial in something reasonable.

 

but seems like the VII is more efficient in this workload. Well guess that’s the only workload where it’s efficient

I will lose approximately 1.2M (10% loss in PPD) (11.76M is maximum and 10.56M is with current settings) per day but I will save 0.5$ per day (38% saving).

[Ithanul]

Interesting the difference your 1080Ti acts with power limits.  Makes me think it is the difference in boost or how the cards BIOS are set for power limits.

 

My 1080Ti at 70% power limit been averaging around 4:15.  Its core temps staying around 60-61C.

Currently where it is set.

I figured it would act like that since it is power limited all the way until 130PL, after that it is voltage limited. Didn't try moving CC above my usual as I like them here. 

Mine on 70% drops CC way too low to be viable.

GTX 1080 Ti Gigabyte 11GB Gaming, cost me 350 euro and here you can see my current settings:

 

Max CC was 2063 while folding.

 

 

[Metallus97]

Ok... I cloud not resist and did the power mod form IgorsLab

My VII is pulling 380W and doing one Work unit in 3:30min now. This has gotten me above 10mPPD.

But I will only keep this until I reach the gold Badge here and then dial things back to non extended Core OC and also to 300W.

I think running this for long could damage the GPU. Although its super impressive

Darn, that clock at that voltage.  Yeah, I say that is golden one.  49C temp too.  Water cool or air cooled?

 

Re-looks at pic, ok, how high of a power limit does that have?  I see it at 90%, but it looks like it goes pretty darn far.

How is the temps and voltage?

You can sometimes be surprise the abuse a GPU can take.

 

I had a Powercolor 7970 in the past that was my 24/7 cruncher.  It would hold OC through folding, crypto mining, and BOINC crunching.  It would get around 70-77C on the air cooler, but it kept on going like a tank.  Traded to a chap call Tictoc on OCN.  He is till using 7970s to crunch with in BOINC.  I should ask him if that 7970 is still going strong.

Temp is 55C but hotspot is close to throttle at 105C (yep that's fine for a VII they throttle at 110C junction)

Voltage is 1,294V but I am working on lowering it AMDs limit vor VCore is something 1,220V

Ah, yeah, if the stated limit is that for voltage than getting at or below is a good idea.

Yeh so what the mod does is it increases those limits over AMDs spec! Therefore I am now running a litte more than they suggest. Their max OC power limit is +20%, but I modded it to be +70% and I am verry well using that. Limiting factor at this time is clearly the hotspot temperature, although its on liquid metal+full water block with my water bing 3-5C over ambient and the fans being HELLALOUD  . I mean the card is made to pull 250W and is close to 380W now lol. Wont run that for long!

 

I am plaining on running stock OC limit voltages but with open power target for the longer run. AM I correct in the assumption that more power draw is fine for the card at "allowed voltages" and being cooled properly?

Yep, if you can keep temperatures in line and voltage in a safe range for that specific model of card, you should be fine.  Of course, when overclocking, one always runs a higher risk of a card dying.

 

Before I had my 1080Ti, I had two water cooled GTX980Tis with custom BIOS that pulled a slight higher voltage than was consider safe (at least if air cooling).  1.275 for voltage, boost disabled, so clocks had to be hard set manual through software.  The cards would run 1540-1560MHz when crunching.  The power usage was decently high for those as well.  Can't remember the exact pull, but I put it like this, I could not safely run that system on my 900W UPS as it pulled more than that UPS could handle.  Didn't help that the same system had a water cooled J Batch 5960X running at 4.6GHz daily (it could do 4.8GHz, but the voltage was in a range I did not feel was safe for 24/7 usage).

 

In mean time, trying to see if my 1080Ti can do those clocks at that voltage that Gigabyte Gaming model is doing.  Yep, nope, it black screen.  So far though, it is doing 1746-1759MHz at around 842-850mV with temps at 63C air cooled.

O nice, it knock the time down to 4:00.  If this is solid, think I may leave my 1080Ti at these settings now.

 

I mostly do power limiting now to see what I can get out of lower voltage.  Mostly because with the vBIOS on Pascal and up being locked and un-modifiable vBIOS on the desktop chips, the fun is quite not there for pushing max clocks.  There is cross flashing of vBIOS, but I stay away from that as that is a higher risk of bricking a card.  Kinda the reason I hope to later nab an AMD card again since those can still be tinkered with their vBIOS.

Ah, sorry. Forgot to mention. I use 90% only while doing collatz as it pulls around 100W less than when it is max overclocked and adds maybe 5-10 seconds per WU so this is a sweet spot for it.

 

While folding however, I just put everything to maximum and that is when it achieves 2063 Core Clock.

 

120% is maximum PL.

 

Also, this GPU is sitting in open case in relatively cold place (CNC machines are located there but they are currently not working so ambient temperature is between 15C and 25C, but usually closer to 15C) and one corsair fan is sitting on top of the card and pulling out hot air. I'll try to make some photos tomorrow morning.

 

And yeah, that is truly one golden card there... My watercooled Aorus 1080 Ti is nowhere near that level of OC... Maximum I can put on it is +60 which yields around 2025-2050CC but it pulls around 150W more than usual.

And with that heavy OC at F@H you don’t get errors?
