I keep my crunching GPUs at 65C or under. I've also had to turn down the OC on these cards over time to stay stable.
I've recently noticed that when I STOP mining, my screen gets all flickery. My main machine is dual 5870s in crossfire. I rebooted and turned off the overclock and it is ok now.
Flickery thoughts drivers#
On my 5770 machine, i had the video drivers crash and started getting hardware errors in GUIMiner. Now, after a few months of solid mining, i've noticed a few strange things recently. The last one is set to 80C for some reason. This is actually where the factory fan settings let 3 of my cards get to. I have 2 5770s, they have been good hashers.Īs far as card temps, I've heard that 90C or under is ok. Now, if you want it for gaming + mining, that's another story. Probably better to buy BTC right now than to buy hardware to mine it. On the 5770, I don't know that I would be buying any new hardware for mining at this difficulty/price. Is it safe for the cards to run sustained at 95C?
A question for people with higher end radeons, what are your temp targets for running the cards long term? I am trying to keep my 6970s at 85C or lower, while the factory fan settings will let them get up to 95C if I set the fans to auto. Only issue is if you are trying to keep your mining setup compact, you might want to get a higher hashrate card since the 5770 takes 2 slots (typical mobo could only take 2). That's a good deal, the 5770s have excellent performance per watt, one of the highest. Maybe it'll stir up a conversation! haha :) Easy enough.īut what happens when we begin to approach the 21 (or 22) million BTC limit? Will the value of the BTC increase enormously because of the lack of supply? If this happens, then won't mining be necessary? What will the value of a block be at that point if the value is halved every 210,000 blocks?Īnyway, just some food for thought for the time being. And naturally as more miners ensue, difficulty increases, price goes down, miners stop mining and resort to buying instead. As the price of USD/BTC increases (more USD per coin), then mining makes more sense since people don't want to buy them. With my basic understanding of economics, my background in amateur investing, and plenty of reading materials over at the BitCoin Economics forum ( ), I began wondering if it is really worth it to mine.
The other question at the forefront of my mind falls back to the issue of feasibility.
Nevertheless, I was just curious how others obtained such high generation rates.
Flickery thoughts generator#
Since the cluster has 2 x NVIDIA Tesla “Fermi” M2050, I figured that might be the most reliable Hash generator at $2.16 an hour for a linux box. While thinking of clusters, I began looking to services such as Amazon's EC2 Cluster GPU instances. To start, out of curiosity, how do people usually achieve monstrous hashrates over 3000 Mhash/s? That would require quite the cluster of computers running HD 6990s, at least assuming that the GPU hardware chart stating HD 6990x3 would produce roughly 2000 Mhash/s is correct. Hello everyone! Just joined up to the bitcoin mining community here at Ars a few days ago and am happy to be contributing my 80 Mhash/s (as little of an amount as that is).Īs my head spins with questions mainly pertaining to economic feasibility in the long run (given the finite number of bitcoins that can be theoretically developed), I'm pressed to start asking you guys things that come to mind (and that I haven't quite found answers to yet).
