Very nice.. what drivers and sdk are you using? What power supply do you have? cheers! |

you can get the memclock lower than that if you use msi afterburner 2.3.0 with the two added ati files in the directory. The final step is to never follow the reboot it asks for as that locks out the memclock control for some reason. See if that works for you, it should save dome more power and heat.
I don't think from what I have read that lowering the memory will get the hash rate higher, I think it just lowers power usage correct? Currently not paying for power tho  |

Just thought I would try to start a thread where we could collect the a list of 7970's and what rate your pushing them. Card, Drivers, OS etc:- Card Name:
- Card ID:
- Catalyst Driver:
- ASIC Quality (GPU-Z):
- AMD Stream SDK:
- OS:
- Voltage Unlocked:
OC Settings:- Core GPU:
- Memory:
- Voltage
- Boost:
Miner Info:- Miner:
- Config Options:
- Hash Rates:
- GPU Temp:
Screen shot if any.. Am I missing something? Also your settings for your card should be running stable and not have to baby sit it please. |

Has anyone adopted this to work with Eloipool? I have bitcoind, eloipool up and running, trying simple coin (yes its old and outdated, I just want to see it work on my local test machines) im seeing these errors in apache when viewing a page [Thu Apr 18 13:13:05 2013] [error] [client 172.18.1.240] PHP Warning: array_key_exists() expects parameter 2 to be array, boolean given in /var/www/includes/stats.php on line 268, referer: http://172.18.251.184/my_stats.php

Did I miss something or is this just incompatible? |

Avalon 66 GH/sec miners hold 240 chips IIRC. So that means that each board in their miners hold 80 chips, and each chip runs 275MH/sec. If you bought 10 chips you should reasonably expect to have a 2.75GH/sec miner. Not bad for $80 or so?
Yea i wanted to buy more but my btc account = 0 now  .. I prefer to do like 40 chips, and use this project.. also is the author of this thread active here? |

@Graet Thanks for taking the time to respond. Yea I need to do homework and was already familiar with the 2 block version change. Maybe you can help with some clarification. You state that I need to have some back up btc's to fund bad luck, im assuming this is the case if the server dies, database of users gets wiped etc.. I have about 10k in BTC right now but as I saw mainly wanted to start this as a private area for my friends about 30 of us pushing about 10G and I have an avalon on order, plus just bought 20+ chips for a diy project if that comes though. I think im leaning on stratum system, eliopool is interesting but debugging and seems much easier with the stratum protocol and most miners now are enabling this, not to mention the packets go over tcp vs http proto. I'm a full blown web developer of 10 years so Ill look at simple coin and prob take the things they did and roll my own into much more secure front end (well as secure as secure things can be . I'm not sure what mmfce front end refers to. I would prob set up the private one with a small server to see how things go and develop over time on this, ideally if i ever wanted to push it to more people or if they wanted to join prob be a standard stack of 2 load balancers, a few web front ends, backend, and nosql db. The question I cannot find is that you set up a wallet lets say the sites wallet, people join, they mine for that wallet and that wallet gets filled with btc, the users shares are tracked, and they have an option to pay out, aka send from master wallet to users wallet.. is that how it goes, or is my thinking wrong? |

Anyone know the estimated hash rate per chip? For example, buying 10 chips and using the dyi project can anyone care to guess potential hash rate.. I heard or maybe I could be wrong the selling avalon boxes have 240 chips in them.. ? I just bought 10 chips and might buy more, but the boards are for 10 chips only is that correct? looking forward to this project and the chips when they arrive  |

Hi, I was wondering if anyone had a guide or pointers on how to set up your own pooling server, I want to set one up my friend and I can mine with, and eventually turn it into something others can join.
I have several ubuntu servers with lots of ram and disk space at various hosts around the world.
I know their is p2pool, but is that what sites like btcguild, or any other pool that users can join run or is their some other underlying software that is the backbone for the system?
Ideally I would build my own front end which is quite easy it seems since a lot of the commands are json ..
but anyone point me into a direction for software to start a private pool system on ubuntu which cgminer and others can connect to?

Hi anyone here hashing away at maxbtc.com ? Im pushing some hashes their way but when I try to contact support their support page doesnt work and well their forum section is deleted.. not much of a good sign.. ??
anyone?

Have an update. Figured I'd bump.
Reference OEM 7970, 13.3 beta, SDK that came with it. CGMiner 2.11.4, Diablo kernel, Worksize 256, Default vectors (1), intensity 11, 2 GPU Threads (default). Don't need to specify any other options aside from pool and GPU speeds. 1185 Core, 300 memory.
713.2 MHash/sec, or ~0.60186 MHash/MHz.
Running with 1 GPU thread was about 700 on the nose. Also, I have not experimented with all the combinations quite yet.
Edit: On another 7970, I was able to get slightly different core clocks, namely 1220/300, and I tested other kernel combinations and let them hash out for about 4-8 hours to get a good average that wouldn't fluctuate. Increasing vectors decreased hashrate significantly. Increasing threads beyond 2 either decreased hashrate significantly or caused a driver crash and recover. The default GPU threads (2) and default vectors (1) seem to be optimal.
730.1 MHash/sec (0.59844 MHash/MHz) with poclbm kernel and worksize=256
731.3 MHash/sec (0.59943 MHash/MHz) with poclbm kernel and worksize=128
728.1 MHash/sec (0.59680 MHash/MHz) with poclbm kernel and worksize=64 (This is the default setting.)
730.8 MHash/sec (0.59902 MHash/MHz) with diablo kernel and worksize=256
731.7 MHash/sec (0.59975 MHash/MHz) with diablo kernel and worksize=128
726.6 MHash/sec (0.59557 MHash/MHz) with diablo kernel and worksize=64
The hashrate per MHz seems to be slightly lower, probably because of a lower RAM:Core ratio. I will increase it slightly to see if I can eek out a slightly better MHash/MHz.
great update, thanks for your info.. |

So the max I have been able to push my 680 with out oc , is between 120-130.. mostly lows 120's. I would love to even add 100 more but its not my main mining rig just add's to my pool from my other cards.. |

So the thread says going from 134 - 330.. I have yet to see any sort of leap from using other miners or rpcminer at default. I realize that people are working on functions to try to improve that and their efforts are greatly appreciated but, I think all of us would like to see a nice bump in our mining with our nvidia cards.
thoughts?
134 MHash/s to 330 MHash/s is for a Kepler K20 or the consumer version Titan. A big jump with old NVIDIA GPUs is not possible. CGMIner is very near to the maximum power of old NVIDIA GPUs. Al GPUs before Titan has no funnel opertor and need 3 operation for a rotate, the new one need one operation. Ahh ok sorry my bad, thanks for the clarification.. so your saying the 690's and below will still be somewhat limited or same speed with out much boost? I have a gtx 680.. |

what hash rate is this sucker putting out, looks sexy with the red fans!

Can you post your card and cgminer command line please? |

still not working sir
rpcminer-mod-cuda.exe -url=btcguild.com:8332 -user=xxx -password=xxx -gpugrid=2048 -gputhreads=256 -gpu=0 should work for you.. enjoy.. |
|
|

sorry for being noob when i run the rpcminer cuda exe and then i put this
rpcminer-mod-cuda.exe -stratum1.btcguild.com:3333 -user=xxxxxxx -password=xxxxxxx -gpu -aggression=8
why it always say CURL return value= 7?
rpcminer does not use the stratum protocol use btcguild.com:8332 |
