Ars have said that the best they've been able to do is 2025 Mhz @ 84C.

Post: RE: GTX 1070 low performance

Lenovo Legion Y720 is a notebook. "64ms" is not the speed, it's the kernel runtime. MH/s is not the same as MHz.

Post: RE: GTX 1080 FE overclock

You should be able to get at least 400 KH/s out of a GTX 1080 on stock clocks. Look at raising the power limit and changing the PowerMizer mode before you start overclocking.

You're not saying exactly how many "multiple" is, nor what attack you are running. But if you're trying to compare single hash brute force speed to e.g. multihash rule-based attacks, you simply can't ...

Post: RE: GTX 1080 FE Temperature & Power Requirements

You need to push the fans up. They should run < 70C with the fans at 100%. No, you don't need Delta fans to cool a 185W GPU, but you should probably put the side panel back on the case. You literally ...

Something isn't right then, but I'm not sure what. I assume you didn't remove the second half of the backplate to allow airflow into the card on the right (that's why it's removable), but that wouldn'...

Ok so Dev3 is running 15C hotter than Dev4, I bet if you remove the second half of the backplate on Dev4 that Dev3 will run a lot cooler. Don't take it off both cards, just the cards where the backpla...

72-75C is within normal range. As long as you are < 80C you will not throttle.

More airflow? Not sure. You're not the first to complain of high temps, but so far I've not experienced them. But my chassis also push like 1000 CFM of air. Heat isn't the only reason the card can ...

You need to take total system cost into consideration, not just the cost of the cards themselves.

Sounds like you have the 32 bit Nvidia driver installed instead of the 64 bit driver.
