Bitcoin / Mining software (miners) / Re: CGMINER GPU FPGA overc monit fanspd RPC stratum linux/windws/osx/mip/r-pi 2.11.4

on: April 13, 2013, 07:08:08 PM

I'm having a bit of trouble getting cgminer to play nicely with my 7950 and 5830 under Ubuntu 12.04. I understand that mixing 7000 series and 5000 series cards is unsupported and can cause issues with the different SDK revisions, but I'd like to see if it's at all possible to get things working.

I have tried using the pre-built version as well as building from the latest git source.

My Linux is a little rusty, so forgive me if I've made a simple mistake.

I installed the AMD APP SDK v2.5 first (extracted using tar, ran the install script), and then installed v2.7. Did I overwrite the 2.5 install by doing this? Do I need to manually install each SDK and link them myself before building cgminer?

Then I followed the readme instructions to build cgminer. When I run ./cgminer -n I get the following:

Code:

zxian@zxian-bitcoin:~/cgminer/cgminer-build$ ./cgminer -n
 [2013-04-13 11:55:07] CL Platform 0 vendor: Advanced Micro Devices, Inc.

 [2013-04-13 11:55:07] Platform 0 devices: 2

 [2013-04-13 11:55:07] ADL Initialisation Error! Error -1!
 [2013-04-13 11:55:07] 2 GPU devices max detected

There's clearly two things wrong here. First off, the 5830 is not a Tahiti card. Secondly, the ADL seems to fail to initialize (although I do see temperature sensors and fan sensors when I run cgminer).

I think the mis-identification of the second card is leading to my issues when I try to actually mine with it. When I run cgminer, the second card is listed, and I can check all the hardware status. However, the second card activity is zero, but the hash rate seems to be split between the two cards (the 7950 normally gets ~550Mh/s at these settings):

Code:

Even when I disable the second card, the hash rate is split between the two:

Could anyone point me in the right direction to get the 5830 properly recognized? Do I need to manually install the v2.5 SDK somewhere and build a second version of cgminer to use with it? Any help would be much appreciated. Like I said, my Linux is rusty, but give me instructions and I can follow them.

Alternate cryptocurrencies / Altcoin Discussion / Re: Bitparking PPCoin Pool - PPS, Variable Difficulty, Pays Invalids

on: April 05, 2013, 06:32:22 AM

Does anyone happen to know why the reported rate on my user stats is less than what's shown by either guiminer or cgminer? My 7950 is showing about 540MHash/s, while my stats page has been sitting between 460 and 480. I've had a few rejected shares in cgminer, but none fail due to hardware errors (none reported anyways). Thanks in advance!

on: July 01, 2011, 09:16:17 AM

Just a reminder - that GTX480 probably isn't going to generate any significant hashing power compared to the 5830's. I've got 9 5830's up and running under Ubuntu 11.04 using this guide as a basis. I setup a basic script to start the poclbm worker for each of my graphics cards (not in crossfire) and then started each one as a service. Another script runs in the background on each machine to monitor temperatures and adjust fanspeeds accordingly. People generally say use whichever OS you're most comfortable with, but I've found that if you've got any experience with Linux, it's probably one of the best for a dedicated mining rig. Just as a disclaimer, I'm an all-Windows man at home, running a Server 2008R2 domain for my four Windows 7 computers (and yet I still recommend Linux for dedicated mining). I was having some issues with phoenix a while back, and it seems that whatever performance benefit it had over poclbm has gone away now with the recent incorporation of the phatk kernel into poclbm. Hope this helps.

Hamachi works wonders too. The latest Linux client even supports their LogMeIn accounts, so you can manage all your networks from their web interface.

Bitcoin / Bitcoin Technical Support / Redirect network traffic through alternate ports

on: June 25, 2011, 08:24:39 AM

I've got a bit of a technical question regarding network traffic and how to work with the firewall restrictions that are in place. The good - I've got access to a location where I can store my mining rigs with free electricity, and I don't have to worry about the heat in my apartment. The downside - they've blocked all network traffic except for DNS, HTTP, and HTTPS at this location (ports 53, 80, 443). I also have root access to a web server that is outside of this firewall (the web server also happens to be running as a VPN server). Is there any way that I can get my mining rigs online and connecting to my pools 'through' the given ports on the firewall? Most of the pools I've seen use port 8332 as the connection. Any input or suggestions would be appreciated. Thanks in advance!

Bitcoin / Mining / Re: Mining Bitcion using a FREE Windows OS!

Quote from: Dirt Rider on June 24, 2011, 04:20:06 PM un-activated win7 stops working after 30 days - there are ways around that but it is NOT legal. Actually, you can use the 'slmgr -rearm' command to reset the activation timer three times on any Vista/Win7 system. It's perfectly legal and is part of the MSDN documentation. This gives you 120 days total, although I'd still say that either LinuxCoin, Ubuntu, or Hyper-V would be better alternatives overall than having some sort of an activation timebomb on your hands.

Cron is probably your best bet. It's simple and as long as you've got your clock properly synced to your timezone it should manage itself. I've got a script running on cron that runs every 5 minutes just to check that the miners are indeed working and that my graphics cards aren't exploding. It's quick, simple and it works.

Usability and understanding how the system works are two big hurdles to overcome. When I explained the concept to a friend, she really didn't like the idea of the lack of a financial institution that was responsible for her money. Trust in the 'cloud' still isn't quite what it needs to be in order for this to really pick up.

Zxian here. You can find my username in various places around the net, including my long-neglected blog (I really should start posting there again and fix that site up...). Got into mining because it seemed like a fun side-hobby/investment. I've got ~1GH/s going on two systems right now, waiting to see how this all pans out by the fall/winter.

Other / Beginners & Help / Re: With newbie restrictions this forum is turning to shit

on: June 17, 2011, 08:59:01 PM

As someone who used to moderate a fairly high traffic forum (quite a bit larger than this one), having this kind of restriction can be a good thing for the community. It keeps the spammers out, the bads who don't read from just posting 'how do I do this?', and the dedicated people around, since the previous two aren't there.

Other / Beginners & Help / Re: Power Supply Question

on: June 17, 2011, 10:54:13 AM

Actually, Bert has the concept of efficiency and power ratings backwards. A 500W PSU should be able to supply 500W of sustained DC load. If it has a 80% efficiency at full load, it will be drawing 625W AC. All of this is what the power supplies should be able to handle. The sad truth is that many PSU manufacturers tend to overstate their actual power capabilities or simply don't stress test their units properly. That all being said, you don't want to be running your PSU at it's full capacity all the time anyways. It'd be like redlining your car continuously and expecting it to work after 3 months. The 750TX should be able to handle the two 5850's you have with some headroom to spare. I'd check the actual power draw using a Kill-a-watt, and then estimate or look up the efficiency to determine the DC draw on the PSU. A safe estimate would be that between 30-70% load, the PSU would be 80% efficient. Otherwise, count for 75%. The only two websites that I really trust for PSU recommendations are SilentPCReview and Jonny Guru. Both have the methodology to properly test power supplies to their full capability. (I'm a little biased in this regard since I used to work for SPCR).
