1. The 10x0 series (Pascal GPU) decrease the hashrate with every new DAG Epoch - the bigger the DAG - the slower the GPU. I think you see old results. If you mine another coin - ETC for example with only 3GB DAG compared to ETH with near 5GB DAG - you will get 40mh again.
2. you can push the card a little bit with higher core clocks to get the hashrate back, but for sure the power consumption is also higher.
3. don´t play with PL. PL - POWER LIMIT - why setting this? There is no reason. Set a fixed core clock and fixed voltage for the GPU - you can get better results, it is more stable and it makes more sense.
Topic: MSI 1080 hashrate problems please help - page 2. (Read 304 times)
Hi. I am a beginner at best as this is my first attempt on OC or mining in general. I started going straight into pure ETH mining.
My PC is a usual (I think PC gamers PC from few years ago) which can be checked here: https://pcpartpicker.com/list/TnbTMb.
Exact card model MSI GeForce GTX 1080 GAMING X 8GB GDDR5X, GPU BIOS 86.4.17.0.50, nvidia driver: 512.53 (30.0.15.1259) on Windows 10
Before jumping in I watched a tonne of stuff from multiple yt channels and read some topics on forums including here: https://bitcointalksearch.org/topic/--5312518 (just fg.).
I follow the steps of most guides but already fail at step one which is using OhGodAnETHlargementPill or --mt 6 in Trex or -straps 5 in Phoenix. My PC (while GPU is on full stock settings but FAN 90%) just crushes every single time. I have tried all 6 --mt settings and all straps settings to no avail. Even if I try starting the miners on stock settings and then starting OhGodAnETHlargementPill it still cruses.
The only way I can make use of those memory tweakers is to overclock the GPU and then start them. For me it doesnt really make sense but at least I am not in complete hole when it comes to efficiency like when I just go stock settings.
So I went down and up the GPU and MEM speed without the PILL and found the best settings with no crush in miners is GPU +135 and MEM +580. Going minus is dropping the hashrates hard.
So I use MSI afterburner and my numbers while mining are:
Full STOCK no ETHPILL:
GPU #0: MSI GTX 1080 - 22.53 MH/s, [T:66C, P:131W, F:70%, E:171kH/W]
GPU 1898
MEM 5005
BEST high OC settings I can find without ETHPILL:
GPU #0: MSI GTX 1080 - 26.50 MH/s, [T:57C, P:150W, F:70%, E:176kH/W]
GPU +135 (but in afterburner it shows 2050)
MEM +580 (afterburner it shows 5583)
BEST low OC settings I can find without ETHPILL:
GPU #0: MSI GTX 1080 - 25.57 MH/s,
GPU -270 (but in afterburner it shows 1645)
MEM +580 (afterburner it shows 5583)
After a while of playing with this I discovered that when I am running this high OC settings above I can start the ETHPILL and it works to some degree. Numers are better but also power usage is insane:
BEST high OC settings I can find without ETHPILL:
GPU #0: MSI GTX 1080 - 33.14 MH/s, [T:58C, P:168W, F:70%, E:198kH/W]
GPU +135 (but in afterburner it shows 2050)
MEM +580 (afterburner it shows 5583)
So I just cant image this card pulling 170W almost doing 33MHs so I started playing with Power Limit and The best I can come up with is PL 52 which is very low but honestly the first -40 levels do not change shit all. Only after going -41 starts to dip the wattage and MHs with it. Here are the numbers:
GPU #0: MSI GTX 1080 - 29.60 MH/s, [T:51C, P:126W, F:70%, E:239kH/W] (overnight does go to 30.2MHs)
GPU +135 (clock drops in range 1820 - 1860 due to power limitations)
MEM +580
I am running everything with Admin rights 100%.
I basically willing to try anything (maybe except bios flash) since I have run out of ideas here and on this very forum I saw ppl posting the same cards with 30MHs while taking 100W or the cards doing 38-40MHs with more the same Power Usage I currently have. I am sort of stuck in the middle of this with worse of both worlds low MHs and high Power consuption.
Thanks a million.
