Title: Odd figures, results and shares Post by: delinquent on July 11, 2012, 12:28:44 PM OK, I'm brand new to the idea of bitcoin, but I understand roughly how it works. I do however, have a slight problem with GUIMiner.
(I will move this topic as soon as the restrictions are removed) When I utilise my GPU, (ATI Radeon 4800) I get an average of about 820 mhash/s, but I have 15 shares after running it overnight. The results appear fairly decent on bitcoin.cz, I have no problem. However, when I tried my CPU (Intel Celeron E1200 @ 1.6 Ghz (don't laugh I know it's shit)) I get the same average, but no shares, no profit, nada, nothing. Affinity is to both cores, ran overnight, on a seperate account, as per. Is that something I should worry about? I have three more PC's that are waiting for miner installation and long-term mining sessions, all with the same specs, but it's not going to be worth it if I make 1 BC a day. System: Win7 Ultimate 3 GB Ram Celeron e1200 @ 1.6ghz ATI Radeon 4800 PCI FoxConn 45CMX-K My CPU Revision oddly appears as 15.15 when all the other models I've seen are named 15.13, I think I have a line test model or something like that, otherwise, It's a pretty decent, but standard PC. Connection: Latency: 73<>190 ms Bandwidth: 3.1<>7.2 mbps (mobile broadband) Between modem + PC: 12.9Mbps (ave) Title: Re: Odd figures, results and shares Post by: John (John K.) on July 11, 2012, 12:37:51 PM OK, I'm brand new to the idea of bitcoin, but I understand roughly how it works. I do however, have a slight problem with GUIMiner. For starters, there is no card like 'ATI Radeon 4800'. You're either using one of them:(I will move this topic as soon as the restrictions are removed) When I utilise my GPU, (ATI Radeon 4800) I get an average of about 820 mhash/s, but I have 15 shares after running it overnight.

The 15 shares being accepted is speaking things, a 800 mh/s rig would do 15 shares in approximately 20 seconds. Read: https://en.bitcoin.it/wiki/Mining_hardware_comparison for the speeds you're going to expect. Even if you're running core i7 extreme edition, you'll only do like 8-10 mh/s and rack up the electricity bill without a significant amount of bitcoins generated. No CPU is good for bitcoin mining anymore.

Could there be a reason for these spikes? Or should I just assume it's a display or calculation error and proceed as normal?

Are you using the polcbm miner or the phoenix miner?I would recommend you to use CGMiner (https://bitcointalk.org/index.php?topic=28402.0) as GUIMiner is phased out, and lack the newest updates. CGMiner comes with rich features like automatic temp monitoring and self-overclocking.
