Out of curiosity, have you tried switching to 270? I almost feel like mine ran better at 270 than 290. I will test soon and report back, as well as just leaving it with the default clock.
edit: What does the 37.0C mean? I have 39.
RKM 0: 39.0C | 32.70/32.59/32.92Gh/s | A:381 R:1+0(.26%) HW:0/none
lol... Thank you for making my evening, Captain America! 37.0C means the unit is running at 37.0 degrees celcius. It's the temperature of the device at the current moment, provided conveniently in the metric temperature scale currently used by every single country in the world with the exception of the USA, the American Samoas, the US Virgin Islands (excluding Puerto Rico, where they also use celcius, and Guam, where the locals use celcius yet they also have to include Fahrenheit everywhere due to the large 'merican military/civilian presence there), along with Myanmar and Liberia. Should note that Liberia has been in the process of changing everything over to the metric system for I think about 3 years now, and Myanmar announced beginning the process to switch last year, which means soon the USA will be the only one that still refuses to adopt the most accurate (and easiest to learn) system for measuring anything in the world. In celcius (C), water boils at 100C and freezes at 0C.
It's what all the American doctors, pharmacists, astronauts, high detail or precision manufacturers, biologists, chemist, and even drug dealers use. They can't break down a pack to be 28 perfectly even packages on a scale measuring ounces. Also I'd sound like a cunt asking someone if they've got 1/28th of an ounce of weed I can grab. 28 grams in an ounce. You can get gram scales that go to several decimals, even. You can't break an ounce down into individual gram-sized decimals... Can you imagine telling someone you need 0.035274 ounces of anything? Also... pharmaceuticals are all in milligrams... Beyond even possible to think about measuring that in ounces or pounds. I always wondered why America won't let go of the old, confusing British method of measurement, especially during and after they fought a war against each other.
P.S. No hard feelings... Just your post gave me a laugh. I'm assuming you understand what the metric system is, and may or may not use it yourself, but probably thought the number was indicative to something else. Some friends were watching hockey on TV a few months back, I arrived and I don't watch hockey. Then, I noticed that a period is almost done and asked one of them how many periods there were, I thought maybe four. To quote Georges St-Pierre, they were "not impressed".
Thanks again!!!
