Quote Your order has been updated to the following status: BF3STD Did my copy of Battlefield 3 get an STD? What's happening?

Quote from: JoelKatz on October 25, 2011, 08:34:47 PM I'll try to find time to work on it in the next few days. It's hard to refuse a request from someone with perfect hair. I'm flattered! Thanks.

Quote from: JoelKatz awesomeness Is there one in the pipeline for 0.5? The RPC changes are a little too much for me to handle.

Quote from: a2offrb on October 24, 2011, 08:45:25 AM Very usual problem on ubuntu if shutting down client while its downloading blocks. Is there solution to not download blocks from start? Takes 24 h on my old notebook If you don't download the blockchain, you practically can't use the client.

Try emptying ~/.bitcoin/ (except for wallet.dat). Let it redownload the blockchain, something probably got corrupted.

Quote from: error on October 23, 2011, 06:36:35 PM There already is. Add it to your Ignore Boards Preferences. This makes it completely inaccessible, not ideal when the user, for example, gets linked to a post in said sub-forum.

Quote from: MSAvenger on October 23, 2011, 06:32:27 PM Actually I used precompiled binaries from wuala.com. SSE4a is definitely faster than SSSE3/SSE4.1-4.2/AVX in 32bits and slightly faster than Core i7-optimized binaries in 64 bits. 64-bit miner is almost 2 times faster than 32-bit. My CPU is 2600K. Correct! This is true because twobits, whose binaries you are using, compiled his own libraries for minerd specifically for the amd64 miner. You should expect a healthy boost in hash-rate when he gets around to updating said i7 miner.

Quote from: MSAvenger on October 23, 2011, 06:00:30 PM Strange thing: I have the best results on Core i7 with SSE4a version. Come on, my CPU doesn't even support these instructions... Must be the Scrypt so pro-AMD? If you're using GCC 4.6 or later: Code: -march=corei7 Sandy Bridge: Code: -march=corei7-avx

Quote from: kano on October 23, 2011, 03:45:40 PM For those who don't realise it, it is straight forward to work out how long the expected average time to get a block its. Firstly, however, it is of course an expected average time, not an expected time. Meaning that if you got say 1 million blocks, then your average time per block should be close to the calculated value, however, for only a few blocks, the average can vary immensely. According to the Law of Large Numbers, the more blocks you get the closer the average should be to the expected average time. Anyway, the expected average number of hashes to find a block is 2^32 * difficulty. At the moment that is: 2^32 * 0.16800443 or 721,573,532 hashes. So if you hash at 1kh/s your expected average time to find a block will be ~200 hours. If you hash at 10kh/s your expected average will be ~20 hours. If you hash at 100kh/s then your expected average will be ~2hours. etc. Where did you get the 2^32 from?

Solidcoin uses a completely different cryptographic function to generate proof-of-work. This won't work out-of-the-box.

Quote from: Shawshank on October 11, 2011, 11:07:51 PM The success of a currency or commodity can not be based on just accepting CPUs and banning GPUs in mining or whatever silly reason. Initiatives based on those fundamentals are doomed to fail. At the moment I see no viable alternative to Bitcoin in the crypto-currency world. There are no crypto-currencies that offer any advantage that Bitcoin can not offer. Maybe that is why nearly 99% of all value in crypto-currencies are stored in Bitcoin. Sorry, does Bitcoin offer two-and-a-half minute confirmations?

Quote from: cruikshank on October 14, 2011, 05:37:15 AM Why not just buy bitcoins directly? Removes the overhead of hardware, power and heat stoke. Investing in hardware is more secure as you can still recoup part of your original investment if Bitcoin crashes in value by selling the mining hardware on Craigslist or eBay or whatever you use.

Quote from: coinminers on September 19, 2011, 05:31:29 PM Great, thanks! One more question: Are there any best practices to avoid a miner from stopping to work. For example last night the task seems to just have stopped, as it shows in red on deepbit and no mhash average or shares submitted, I did not yet get to check in the server room what it says on the screen, but was just wondering if this is a common issue? If you overclock too high you may get stability issues. Some people recommend flashing the cards' BIOS to underclock the memory and running a distribution of Linux such as Ubuntu Server or Linuxcoin to increase stability. Generally, the more extra bloat you have running, such as desktop window managers, task schedulers and all that crap you get with Windows, the less stable the system. I'd like to stress that this is my personal opinion, some people claim that Windows can deliver an excellent platform for mining.

Quote from: coinminers on September 19, 2011, 06:32:29 AM Aah, interesting, so I can setup a second task for the second card that shows up in the guiminer! I'll try that tomorrow when I get to the cooling room again. One more question: How do I underclock the ram? All I see in the ati overdrive tool is 1250 or more on the slider? Thanks! Nima Grab MSI Afterburner or Sapphire TriXX.
