The difficulty of SIA has skyrocketed since the release of Bitmain A3 which is an ASIC for SIA coin. It is not at all profitable to dual mine SIA.
I'll suggest moving to other coins which support dual mining such as Decred or Lybr.

How are we suppose to assist you without any information about your rig?

Best is to make the rig stable with original bios and then working your way to custom bios for a higher hash rate.
Did you add -dcri 18 in your claymore bat file?
-dcri 6 for single coin mining.

1. Set the PCIe lane speeds to GEN1 for both x16 and x1 slots.
2. Increase the virtual memory to 16 GB.
3. Use latest Claymore version.
4. Uninstall your drivers using DDU in safe mode and intsall blockchain drivers and run ATI patcher.
5. TEST -- 1 (With no overclock and undervolt, do a test for hashrates for half an hour).
6. TEST -- 2 (Now, start to increase memory overclock and core undervolt by small increments until you hit the sweet spot for both).
After you've reached this point, you can easily Dual mine and increase your earning by upto 25%.

If the system is not stable, there can be a few reasons:
1. Overclock is extreme which makes GPU unstable after a few hours.
2. BIOS Mod is causing GPU to hang up.
3. Buggy drivers.
4. High temps of the GPU.

For 1070ti, 36-40 MH/s on ETH is possible but not with 1080.
1080 has a GDDR5X SDRAM which is not optimized for ETH at the moment. It can hardly do 28-30 MH/s while consuming a lot of power.

Hi guys,
I got 8 GPU's running (RX 580) and to get the 8th one on the motherboard I used an M.2 adapter (M.2 SSD To PCI-E Express 4X Adapter)
My motherboard (ASUS PRIME Z270-A).
This setup is working except that the GPU on the M.2 adapter is getting lower hashrates.
In the BIOS, there's a setting for 2x and 4x on the adapter, and I've tried both settings but I still have the same problem.
All my other GPUs have a hashrate of 29.2 MH/s, but the GPU on the M.2 adapter is slower than stock (22 MH/s). I've swapped the cables with another GPU to confirm the issue, it's definitely whichever GPU is on the M.2 adapter that has low hash rate and is fine otherwise.
Is this normal with M.2 adapters? If I should be getting the same hash rate I'm not sure what else to try.
Thanks
I bought a few of these: M2. to PCI-e adapterEach and every adapter worked great and I think it is a good solution going ahead. |

1. For reaching 30+ MH/s with your GPUs, you have to BIOS Mod your cards according to your memory vendor. After that finding the sweet spot of overclocking for each GPU. Then undervolting to reduce power consumption.
2. The error is probably some Driver issue which reads the GPUs temps incorrectly.
Anyway, I'll suggest going with Windows as it will be easier to perform all the activities I state above.

As GTX 1080ti is a beefy GPU. The cooling must be strong to keep the temps in range.
As you're running 2x GTX 1080ti in a case, I'll recommend switching to a new case, possibly Silverstone.
The basic mechanics to keep your system cool is to have an inward and outward flow of air, the quicker the air is renewed in the case, the better the cooling.
The front panel of the case can act as an inward side, so insert some high RPM fans in there whereas the back of the case should have a few fans to push the air outward.

It is an Ethereum Token, you cannot mine ETH token.
If you want to accumulate some, you will have to buy.

You can try different riser versions for the non-detecting card.
I hope you have made changes in the BIOS such as changing PCIe lane speed to GEN1 for x1 and x16.
I'll suggest using nvOC Linux distro, as it is tailored for Nvidia mining rigs.

OverdriveNtool for AMD
Nvidia Inspector for Nvidia.

You can reduce the power limit to see if it takes a toll at the hashrate.
In that way, you can increase the efficiency of the card and reduce some temps too.

Checked GPU-z?
Did you check if they have different memory vendor?

I myself had a lot of problems with the official pool, i.e intensecoin.com/pool Then I switched to this pool: https://intense.hashvault.pro/I recommend you to make a switch, choose a stratum location near to you. (It'll reduce the ping) I see you're using Claymore Miner, give different miners a try. They may provide more hashrate or stability. - Cast XMR, XMR-Stack. |

Yes, that is correct as of now.
Until and unless someone else discovers a way to produce more hashrate in other algorithms.
Vega still performs pretty good but not worth the price as difficulty has caught up.
For the price I'm not seeing it to just have an advantage in 1 algo. Is it true that not many exchanges want to host cryptonight coins? Also have people ever made some kind of modifier drivers that gives higher hash rate,? What is the best pound for pound card out today? The advantage of Vega is long gone. If you would have purchased it when the method for high hashrate in the cryptonitght algorithm for Vega just released. The break-even was in a month or two. Now, its more like six months with the price and difficulty. I don't know if exchanges are deliberately not listing cryptonight coins. No, there is no modified drivers but BIOS mod, power tables and such which provides high hashrates. If you can find RX 5XX series for a good price or GTX 1060 and GTX 1070. They seem the best ATM. |

The GPUs which are able to do 19 MH/s are probably Hynix cards.
The GPUs which are able to do 22-23 MH/s are either Micron or Samsung.
Hynix cannot perform more than 19 MH/s in ETH.

No modern graphics card are compatible with PCI slots.
You'll need a motherboard featuring PCI-e slots for a modern graphics card to work.
