I'm all of a sudden getting
"OpenCL error -4 (0) - cannot create DAG on GPU"
With Claymore 11.7
What is this error again? It's been so long since I've had to deal with it.
EDIT: Nvm, I doubled the pagefile and it's fine.

Buy Ethereum. It is very low right now.

And FYI, trying to plug them into different outlets in the same room will usually not help. Bedrooms are usually wired with a single 15A line.
Long extension cords are also a bad idea.
I highly recommend trying to lower the power usage, even if it means lower hash rates. You can also get higher efficiency power supplies which will decrease the overall heat generated and power used.
The best thing to do is to hire a professional electrician to put in 30A at 240V (or 208V if you have 3 phase). Higher voltages are slightly more efficient. A 30A 240V breaker can provide ~5700W (derated to 80%) safely. This is usually enough for 2-4 rigs, depending on their power usage.

I’m going to upgrade the breaker so it’s 20amp instead of 15. How should I do the surge protectors - split my 2 psus to 2 surge protectors? How do surge protectors limit the amount of power you’re able to receive?
DO NOT DO THIS! NO NO NO! Your wiring can probably only support 15A. If you upgrade the breaker to 20A it will likely cause the wires to overheat and burn your house down. Hire an electrician and put in 30A 240V in your garage then use PDUs to distribute the power. You're asking for trouble by using residential lines. |

CoinTracking not importing all my trades, especially for altcurrencies.
I purchased Pro because it looks like a promising tool. After entering the API feeds from Coinbase, GDax, and Bittrex, I noticed my account holdings were way off. It is showing holdings way higher than I actually have.
I started to do some manual searching through the trades. I noticed that pretty much all of my alt-currency trading on Bittrex is missing. I tried re-doing the import, but they were still missing. I own a little bit of like 10 different coins in Bittrex, but Cointracking is not showing any of them. What gives? Anyone know?

Server power supply.
Parallelminer has 2400w ones. THat's the one you want.

Tribble PSU?  |

Keep all the ETH! Use it instead of fiat for purchases/payments

I'll check out the PDU.
No, I am using NEMA twist lock. I can't remember the number, but like L6-20R or something like that?
I had a professional electrician install it.

Is there a specific product that you can link me to?
I am still confused as to exactly what I'm looking for.
I understand Kill-a-watt is a trademarked item. But, I plug it in, I plug in my PC, and it tells me the watts.
When I search for "Power Meter" the first link is to kill-a-watt, which for reasons mentioned, won't work with 240v.

Kill-a-watt uses the wrong type of plug.
Plus, Kill-a-watt says 100-120v max. 240v is still coming out of the PDU.
Just trying to find a product I can use to accurately measure watts.

The kil-a-watt that I have says it should only be used for 100-120v. I want to check my total wattage being used on my 240v items, but I can't seem to find a product that can do that.
Plus, it wouldn't even fit, because my 240v does't use standard plugs, obviously. I have a NEMA 240v twist-lock connected to a PDU.
Thanks!
What kind of PDU are you using? Many PDUs have network management features, where you can track current for individual outlets and able to disable them if you exceed max amperage. Therefore, you don't even need a energy meter like kill-a-watt, as most professional grade PDUs will have inbuilt feature, which are more advanced than consumer grade energy meters. I have this PDU Dell-AP6031-PDU-4-Outlet-200-240V-24A-Power-Distribution-Unit-5T439 Using these PDU Extensions: HP Proliant Modular PDU Extension Bar HSTNR-PS03 411273-002 And then plug in the PCs using: IEC 320 NEMA C13 C14 10A 18AWG PDU to CPU AC Power Cords All bought on eBay. |

You mean 240v in two phases right? not the 230v single phase used in most of the world. So you can't use a meter designed for a single phase. You can try to use only one phase from that connector to power some miners and the second phase with the other miners. for illustrative purpose:  Yes, its 2 phase. Would a clamp meter work? |

2 issues:
1) Windows can only support 8 of any type of card at one time (8 AMD + 8 nVidia possible)
2) That board can only support max of 8 cards, anyway. The 2nd M.2 is not connected to the PCIe bus. Only the SSD bus.

Make sure there is a display plugged into at least one of the video cards. If you're using the onboard video. Or use headless HDMI

Sounds like your local app hasn't synced with the blockchain.

If you're getting freezing, crashing, or other problems, then it needs to be fixed.
These issues are usually related to overclocking too much, undervolting too much, or your PSU is too weak.
If the miner is plugged into a socket that shared by multiple items, you can max out on power pretty quickly.
Just for reference, most U.S. cables are 15amp 120v = 1,800 watts. So if you have a 1200w miner, your pc running, monitors, phone charger, and vaccuum cleaner, you will quickly overload the circuit.
It's best to put them on their own dedicated 200-240v circuit.
I have my miners running for 300+ hours before needing to restart. Some get to 500+ hours.
