It's a MSI 1070 Gaming X 8g - might has a higher base value already?

but 412 sol/s would be even for a stock 1070 very low, should bring at least ~ 420-430

please share your settings in AF to get to 600sols
if you are using AF

Went ahead and tried that, cleared both cmos and reapplied the BIOS(it was already at the latest version). No luck. Tried with a different miner as well, saw the same behavior, so at least I can say that it's not just ewbf's miner. But why this is happening, can't figure out. Thanks for the advice though.


Yeah, tried doing this multiple times. Unfortunately, always the same result. Don't actually have the sixth card yet, as I saw this problem, wanted to fix it before I sprang for another card. It's really just bizarre, again, the card plugged into the x8 slot when the x16 slot is occupied shows up in device manager, overclocking programs. And the port itself is functional, know this through a pcie wifi card I used. But for some reason it's not picked up by miners. The most annoying thing is, I swear it worked when I had all the pieces loose, hooked up everything loose to test/configure. I was able to use the port and get it working, I'm almost 95% sure. Once I put everything together in the rig is when it stopped working, or so I think. What could have changed, I don't know. Maybe the board is just bad, but no way to know without a multi-week rma that may or may not turn up anything. I'm inclined to say it's functional due to the fact that another device works in the slot, but having a card there is clearly not working. I'll try to clean them again and see if it works, though I'm not holding out too much hope. Thanks for the tip though.

Try to flash update the bios.

Yes, I had the same issue.  Use Display Driver Uninstaller to remove all traces of the Nvidia drivers.  Shutdown.  With all 6 cards connected to the motherboard, restart.  Reinstall Nvidia drivers, wait a long while as it works through all 6 cards.  That solved the problem for me and it was driving me nuts.

Hi,how did you disable the p2 state?I tried here but I still can not.

Ran into an issue, wondering if anyone's seen something similar. Have 5 1080TI's on a win 10 setup, mobo is a gigabyte z97x-gaming 5, it has 6 pcie slots. It has an x16 slot which runs at x16, and an x16 slot running at x8, which shares bandwidth with the full x16 slot. It also has an x16 slot running at x4 speeds, sharing bandwidth with 3 other x1 slots. Toggling the x4 slot to x1 speeds in the BIOS enables it to be used with the x1 slots concurrently.

I would like to move from 5 to 6 cards, and that is where I have a problem...

Has anyone seen something like this? Seems to be a problem with the miner, as again, the card is detected by the OS/various programs, and the slot can even be used by other pcie devices, it's just that the miner doesn't use it to mine if a card is present there at the same time as a card in the x16 slot. Wasn't able to find an alternative mining program to just test and see if it would make full use of the cards in the expected manners, the few I tried didn't work very well. If anyone has a solution to this issue, would be great, or at least a suggestion of another mining program to use which can support 5+ nvidia gpus, just so I can test and see if it works on that.

Why not just tweak it and observe the hashrate changes?)
On my 1080 I noticed that disabling P2 CUDA downclock in driver brings back memory frequency from 9500 to stock 10500 (factory overclocked bios) and it makes a very noticeable impact on hashrate, overclocking further to 11-11.1 GHz gives almost no gain. GPU is easier, just overclock until it hits desirable temps/TDP, I limited it to 80% PL and got 580 sols @ 180 W @ 68°C. Unlimited stock goes to 90% PL and overclocked to 100%, which is about 610 sols, but it becomes hot (72+) and noisy

Trying this out on a single EVGA 1070, and get about 400-410 sol/s. 4.05 sol/w.
Went to core +144 and memory to +569 and at 412 sol/s. 4.00 sol/w.

Definitely worth playing around with the settings.

get 470 sols with 68% TDP, 65°C Temp Limit, +100 Core, +500 Memory, 75% Fanspeed

can anyone share your 1070 settings and hashrate?

Ran into an issue, wondering if anyone's seen something similar. Have 5 1080TI's on a win 10 setup, mobo is a gigabyte z97x-gaming 5, it has 6 pcie slots. It has an x16 slot which runs at x16, and an x16 slot running at x8, which shares bandwidth with the full x16 slot.

I would like to move from 5 to 6 cards, and that is where I have a problem. I'm having an issue with the pcie x16/8 slots. Specifically, cannot get the miner to utilize 2 cards if they are in the x16 and x8 slot respectively. The x16 slot by itself works fine. The x8 slot by itself works fine. But if they both have a card, only the x16 slot card is picked up. So at the moment, I have to use the x16 slot, the x4 slot, and the 3 x1 slots, all of which work fine together. But again, want to add a last card to this rig. Curiously, it's not like the card in the x8 slot is not detected if there is something in the x16 slot. It shows up as a device in device manager, and various overclocking programs can see it as well. It just wont be picked up by the miner, only 4 cards get used. It only gets used if I pull the card out of the full x16 slot. I even tried putting in a pcie wifi card in the x8 slot with the 5 other cards running. That not only detected and installed, but it connected and was in use, meaning for sure there is no issue with the slot running when the full x16 slot is in use.
