Topic: Can´t find the sweet spot with my GPU - Help wanted: evga 1070 SC Black edition (Read 695 times)

The funny thing is that I purchased all those cards used on eBay for between $340 and $390 with free shipping over the last 4 months.  The only card I purchased new was the FE that I got directly from nvidia the week it was released.

Yeah, the 2400W Delta is overkill, but it is nice and quiet with only ~1,100W being drawn from it.  I have a 8x1080Ti rig that draws 1800W from a Delta, and it is pretty loud.  A 2nd 8x 1080Ti rig is in the living room, and I had to put a 2nd Delta on it to quiet it down.

The Delta's are a lot cheaper than the EVGA 1200P2, let alone the 1600P2 or the Corsair AX1500i (I run them all in various rigs).

Must be nice to have won the memory sweepstakes on so many cards.

Isn't that Delta PS a bit overkill though?

One of my rigs has 7 EVGA 1070's of varying vintages, along with a 1070FE.  Here's the rig:



Left to right I have:

0 1st gen SC
1 1st gen SC
2 1st gen SC
3 2nd gen SC
4 2nd gen SC2
5 FTW
6 FTW2
7 FE

They all share these settings:

POWERLIMIT_WATTS=120
CORE_OVERCLOCK=130
MEMORY_OVERCLOCK=1100 (550 in windows)

And they average 478 Sol/S and just a tick above 4 Sol/W.

QuintLeo:  Your stats are similar to mine.  So this seems to be the sweet spot for me.
I keep the memory up because i auto-switch between eth and equi quite often and I don`t want to bother with changing the mem vs core every time.
    .... and yes...lowering below 65% drops the hashrate a lot.

 EVGA SC 1070 (also Gigabyte ITX 1070 but the EVGA was happier than the Gigabyte in the 90-100 watt range)

100 watts (appx 66% TDP, but this is in a LINUX system where the PL is set directly in watts) +100 core +100 memory for just over 400 sol/s.

 Lower than 100 watts was dropping the hashrate FAST and losing efficiency on both cards but more so on the Gigabyte.
 Higher wattage - efficiency drops slowly but hashrate went up fairly well.

 +150 core = unstable crashy card.
 Higher memory (up to +450 or so) gave NO hashrate improvement and past +300 gave hashrate DROP.
 Past +450 on memory = unstable crashy card.

 The "Black Edition" was the original SC model, the only real difference to the "non Black Edition" SC is lack of LED lighting other than the white "EVGA GTX 1070" edge light, and the color of the plastic on the fan mount/shroud.

 I'm not sure what memory brand the one I did the testing on has in it.

 I do have it at 60% fan but it's going to end up in a mining room that gets fairly hot in the summer, where I have it sitting right now 40% would be comfortable (though not 51 degree comfortable, it's running about 52 right now).
 Room temp it's in right now is 29-30C but the mining room in the summer gets up to about 38C.

 I greatly prefer the EVGA SC 1070 ti model, as it will push more like 440-450 sol/s at the SAME 100 watt power level, 460-470 at 106 watts, while the cost/sol is a hair better than the EVGA SC 1070 at recent pricing (more so at total system cost for a same-card-count rig).
 

Evga 1070 SC  
65% Power, +100 core, +500 memory  (Micron)

417 sol/sec / roughly 98 watts.  (150W TDP is the default on 100%).
51C at 40% FAN,  
26- 27C room temperature

That works well for me from power vs hash vs temp perspective.
More Core usually reboots the PC after a while, more memory brings the magic artifacts on the screen.

The "Black Edition" is a bit crappier (thus the 20$ difference) than the regular SC, but should do something similar.

p.s.
From all my 1070 (I have Asus, Evga, Gigabyte and the Nvidia FE), the Evga 1070 SC is my favorite.

p.s.2.  The "return on investment" IS actually less than a year at current rates on the 1070 but it can always change next year.

Ask me again in a week, I'm in process of shifting a BUNCH of cards around as I move to turning my old "folding" 3-card rigs into 5 card "riser" rigs - and will be doing some major "find the efficient point" type tuning work on the various cards as I go.

Quint what are your settings on normal 1070 SC?

 85% on THOSE cards though is 204 watts - which is a lot more than 100% TDP on the EVGA 1070 SC (which only has a 151 watt TDP).

 As I recall, the EVGA FTW models also have a higher TDP (180 watts I think), but I don't have any of those myself so not sure there.


 My SC cards don't handle +550 memory worth beans long-term, but they do handle +500 well - I have the originals that didn't have the added thermal pads though.
 Probably depends on the memory in a specific card.

Here is my setup on that same card:

EVGA 1070 SC

ETH

Power: 65%
Core: -50
Memory: +550

32.X MH/s

ZEC:

Power 81
Core: 125
Memory: +400

450-460 sols

===================

EVGA 1070 FTW

ETH

Power: 55%
Core: -175
Memory: +575

32.X MH/s

I don't have my ZEC profile loaded but I think it's 65% +100 and +400 on the FTW cards.

ETH + DCR requires a bit of work and a lot more power.

i have the 1070ftw and ftw2's evga.  same brand, same chipset, but different models from yours.

for zec, i run them at +125/+500/60tdp.

they all run around 450sol or so.

yours should do roughly the same speeds. 

make sure you set your fan profile curve manually, since the gpu only measures heat at the clock and not the vrm.  leaving it at default makes the vrm run a bit too hot, causing the gpu to underperform/crash etc.

I just got a pny 1070 it on the way and wondering how this card performs this is my first nvidia card I have all 470/570 but one rig has r9 270/280/290/390 and they love power so I'm trying to update these and now that nvidia is finally getting support I figured I'd give 1070s a try

Yeah the MSI is better than the 1070 Black SC or 1070 SC in general. If you run a EBGA 1070 FTW or SC2 or Aorus 1070 you can do 75% +100-125 core + 575 Mem and reach 470-500 Sol/s at a 3.5+ Sol/W

I have MSI GeForce GTX 1070 GAMING X 8G and I achieve 450-460 Sol/s easily at 85% +90 Core +645 Mem with EWBF's CUDA Zcash miner. This card can take a lot more punishment than my other 1070s from ASUS but there are diminishing returns in further overclocking.

I am running those on a system and am running them 85% +120 Core +700 Mem 75% fan speed. That is giving 440-450 Sol/s at 120-130W. It stays at the 3.5 Sol/W range with those settings.

73% power is too low for these single plug 1070s trying to get a good OC and you wont be able to do a high Mem if you keep the power that low.

That system is 4 1070 Black SC 4 1070 SC z270-A 8GB Ram 120 GB SSD, 2 850W Power supplies.

If i do 600 - the system becomes unstable.
Might work for a couple of hours, but then the screen starts acting wierd and the miner stops.

Wish I had samsung ..

But thx alot for your help

I have asus dual 1060 6gb cards with micron memory and my mem clock is +610 in afterburner with +150core clock and 59% tdp

Hi everyone.

I recently got my first rig up and running, but i'm having problems finding the sweet spot for good hashing rates.
Is there anyone who can give a quick glance and take a look ?

This is my typical hashing rate for zcash:
EVGA GTX 1070 SC Black Edition, Micron mem.
Zec Miner 0.3.4b

GPU0: 398 sol/s, temp 62C
GPU1: 409 sol/s, temp 53 C
GPU2: 402 sol/s, temp 59 C
GPU3: 409 sol/s, temp 53 C
GPU4: 411 sol/s, temp 57C
GPU5: 339 sol/s, temp 61 C

In afterburner my settings are:

Power: 73%, Core: +114 and Mem +334

The system:

Z170A gaming pro carbon, 8 gb ram, 120 gb ssd.
Cosair HX1000 that powers MB, CPU and GPU0,GPU1,GPU2 & GPU3
Cosair VS 550 that powers GPU4 & GPU5

My hashing rate is lower than expected and I would love to get it up, to a point where payback period is less than a year

Is there anyone out there who can help me ?
What timings ? What to do ? what to look for ?

Any help would be very appreciated
