There has to be an optimised miner here - im not getting anywhere near what I should be with 4000 cores on it. (Yes cores).
Who is mining this with a large farm and what stats are you getting?
I though I had a lot of cores going at ~100. I had problems getting more then ~100 threads mining on a single riecoind instance, so in desperation I switched to solomining on each host. I'll have to merge the wallets later, but I am getting about 500000 to 1200000 knumbers/s (per host) and from the few wallets I am monitoring I have found zero blocks. Edit: yes I solo mine on each host. Much easier. the easiest approach so this is to use the same copy of wallet.dat on each instance. you should generate is with more keys first though (launch riecoind -keypool=<n> ). I usually suggest 1000, though in practice with this coin 100 should be plenty (thats 100 blocks mined per instance before wallet deviation). That's the way I approach it anyway. I'm still convinced there is an opimised miner out there. I should be getting blocks every 14 mins now, and I'm not. I have had 4 blocks since launch with 4000 cores I had a wallet with 10000 keys pre-generated prior to the launch but I didn't have it distributed to the various hosts, and with all the attempts at restarting riecoind I didn't trust it's integrity. Also, what's to say each host is not testing the same pseudoprimes? How are the candidate numbers chosen and how is the PRNG seeded? Is it seeded with your receiving address and the previous block hash? If so, then you might have 4000 hosts all testing the exact same numbers. |

+1 for you! It works and I'm actually showing non-zero pps on my 16-core opteron system now. It's only 1-2 primespersec but it's an improvement! # primecoind getinfo

I'm mining with some cores, CPUs are burning

Nobody? I see in this entire thread others had this problem too. It MUST be more than one, it's 15 cores running... Give it a few minutes and the rate will show... -tb- Edit: nevermind. just noticed it has been more than a few minutes for you. I have this problem too. There is something broken in the linux client. It mines at 0 pps on all my gentoo computers, but Ubuntu and windows work. I mined from the beginning and the only computer I can get going is my crappy windows box. |

Mining with the Linux client does not work. I get 0 primes per second even though my processors are pegged at 100%...
Odd, how long as it been running? I'm getting ~40 on an ancient Xubuntu rig. Several minutes now. It even mines at 0 pps on the testnet. My windows box works just fine though at ~130pps. ./primecoind getmininginfo { "blocks" : 1046, "currentblocksize" : 1000, "currentblocktx" : 0, "errors" : "", "generate" : true, "genproclimit" : -1, "primespersec" : 0, "pooledtx" : 0, "testnet" : false } And primecoind (both the download from sourceforge and the compiled source) are maxing out all my cores at 100% |

I haven't tuned the software on these rigs for minimum overhead and I haven't overclocked the video cards yet either. Currently the farm is running at ~6GH/s or ~500MH/s for each 7970. I built it as fast as I could to get the mining started so they are currently running Ubuntu desktop. Ultimately I plan to create a Gentoo USB install that automatically tunes and mines each rig.
Just curious, you're driving 3 7970 with a 850W PSU??? Considering that each GPU is taking 250-300W, this is pushing the limit a little bit, isn't it? Are you tweaking the GPUs voltage to make this setup be stable? I haven't tuned anything. When I chose the hardware, I estimated 250W per 7970, then went for an 850W. The PSU has a single 12V rail so all 4 rigs appear to be running stable -- even through some very bad thunder storms. I have not overclocked/underclocked anything and the voltages are currently all stock. I just haven't had time to build a decent Live USB miner that has the software on it to do that. |

That's exactly what I did. I used a dremel and just drilled out the rivets on the sides I wanted to cut away. I had to use some tin snips to cut away some of the bottom of the case as the 3rd video card would have used up a 9th PCIe slot which the cases didn't have. The cases are new and were about $25 each which is probably cheaper than some of the custom case builds I've seen. |

No replies? Well, I'll risk it and go with the ASUS F2A85-V Pro then and see how it works.

I'm planning on building a 3x7970 mining rig using either the ASUS F2A85-V Pro motherboard or the ASUS M5A99X Evo R2.0. Does anybody have experience using these boards with all three x16 slots populated with 7970's without using risers? My plan is to remove the side panels from the case to improve cooling with a walmart boxfan  It looks like the ASUS F2A85-V Pro has explicit support for tripple GPU configurations, but will the onboard video complicate things? I should note that I will be using Linux on this system and not windows.   |

5 is just right. With this, I'm free!

Nobody wants to sell their FPGA to me?

Hi, I would like to post in the mining forums. I'm interested in writing my own firmware for FPGA mining (even though ASIC is starting to dominate).
Next generation ASIC miners will need to be tested and verified on FPGA's before the ASIC's can be manufactured. Also, any cryptographic discoveries will benefit FPGA miners first.

I want to buy one of the Lancelot FPGA development boards. Are they still being sold?
My intention is to experiment with the FPGA board. When I'm not learning how to write code and flash firmware, and when I'm sleeping the board can pay for itself by mining bitcoins.
I know ASIC's are right around the corner, but I can always buy some of those too.

Hi guys,
I just started mining and I've almost earned my first bitcoin. Only 0.3 coins left to go until I'm at 1.0 bitcoins!
Does anybody know if the Lancelot FPGA's are still being manufactured and sold? I'm interested in buying one.
