1  Other / CPU/GPU Bitcoin mining hardware / Asking for suggestions on a 7970 -- Mining and Gaming rig on: August 15, 2012, 05:43:37 PM
I already have a rig that has a good number of 5870's and 5850's that has been solid.  But, I am wanting to upgrade the tired old Nvidia card in my gaming rig with an ATI and have it mine while idle.

So here's my question.  What 7970 card do you guys suggest that would be good for both mining and gaming?  There are so many different manufacturers to choose from, and none of them really say if they are a "reference" card or not. 

thanks in advance!

Just checking to see if anyone has heard anything from BFL about the SC's.  I pre-ordered one, and paid with BTC, but haven't seen any news annoucements or really anything yet.
Are they still going to hit October?

4  Other / CPU/GPU Bitcoin mining hardware / Another Sapphire 5850 fan failure :( How long to RMA? on: July 03, 2011, 07:00:59 PM
Well, it seems I am another miner that has suffered a fan failure on one of my Sapphire 5850's Sad  I have three of them, and one of them started becoming unstable while mining, and would intermittenly just stop hashing, so after troubleshooting, I realized the temps on one particular GPU would just shoot up right after starting a miner. Within  few minutes I realized the fan was barely spinning, and causing the GPU to overheat. I cant get the fan to spin any faster by software means, so I am assuming its dying like the many others.
So, I am RMA'ing back to Sapphire.  Has anyone had to do this before? How long did it take before you got yours back?
5  Economy / Trading Discussion / MtGox delayed opening...yet again! on: June 25, 2011, 04:40:41 AM
I dont know about you folks, but after these relentless delays and unkept promises, I am pulling every singe USD and BTC I have out of Mt.Gox the minute it opens.  I was patient during the whole fiasco and I wanted to keep using them, but as they keep delaying the process more and more, I find myself loosing my patience.

I would speculate there to be a mass exodus once they open up.

Last person out, please close and lock the door behind you Smiley

Does anyone have one of these to give some feedback on it?  It looks alot better than the newegg boxes and pizza boxes most rigs are cobbled together in  Smiley
8  Alternate cryptocurrencies / Mining (Altcoins) / Corsair 850TX PSU for $134 -- Will it support 3 5850's and a 5870? on: June 09, 2011, 05:23:11 AM
I just purchased a Corsair 850TX 850 watt PSU on Amazon for about 134 shipped (Im a Prime member) and I was wondering if you guys think it will power 3 Sapphire HD5850's and a Gigabyte HD5870 rig?

Here is the link for the specs:

9  Bitcoin / Mining / Need PSU Suggestions for 3 HD5850's and 1 HD5870 please on: June 09, 2011, 03:16:52 AM
Hey everyone,  I just picked up a HD5870 and was going to add it to my current rig... well this 5870 was asking a little much from the PSU and it cant power it and the other 3 GPU's. The one I have powered the 3 5850's great, but this 5870 puts it over its limit Sad So, I am asking for your advice on a good PSU.
Heres my setup:

Sempron 140 proc
2.5" laptop 5400 sata drive
3 Sapphire HD5850 (would like to overclock them to around 900 core, 300 ram)
1 gigabyte HD5870 (would like to overclock it as well to somewhere around 950 core, 350 ram)
I also have an ePower 420 watt "juice box" that supplies power to GPU's but I dont think I trust it with more than 1 GPU. Maybe powering 2 of the 5850's it might be ok.

My case has 2 120mm fans in it.

Please give me some good suggestions to power this beast, and allow me to overclock my GPU's for maximum mining effeciency.

Thanks in advance!
10  Bitcoin / Mining / Cant get HD5850's to overclock and set fan speed in ubuntu on: June 03, 2011, 02:19:13 PM
I have 3 Sapphire HD5850's running.  I have tried to overclock them but I am not getting very stable numbers. Each card is identical, and i cannot get them to clock to the same speeds. I can barely even overclock one of them Sad

Heres my setup:
Ubuntu 11.04 64 bit running headless, GDM is set to not start on boot, and I have a script in /etc/init to start X
Catalyst 11.5
AMD SDK 2.4

On GPU 0 I can only get it to stay stable at 800 gpu 300 mem. If I go any higher, I get a system lock and have to reboot to free it.  This is the GPU that I used to install Ubuntu, but I am currently running it headless.  Also I cannot get the damn speed to set on boot using my start script. I will post the script below:


Code:
#!/bin/bash
# ${1} is used as a variable for the username, password and for the gpu device number.  Ex. mineruser0, minerpass0, Device=0 or mineruser1, minerpass1, Device=1
      HOMEDIR=/home/bitcoin
      MINERSERV=btcguild.com:8332
      MINERUSER=MYMINER${1}
      MINERPASS=MINERPASS

      export AMDAPPSDKROOT=${HOMEDIR}/AMD-APP-SDK-v2.4-lnx64/
      export AMDAPPSDKSAMPLESROOT=${HOMEDIR}/AMD-APP-SDK-v2.4-lnx64/
      export LD_LIBRARY_PATH=${AMDAPPSDKROOT}lib/x86_64:${LD_LIBRARY_PATH}

      #Overclock GPU0 to 800 Mhz and set fan seepd
      DISPLAY=:0 aticonfig --pplib-cmd "set fanspeed 0 75"
      DISPLAY=:0 aticonfig --od-enable --adapter=all
      DISPLAY=:0 aticonfig --od-setclocks=800,300 --adapter=${1}
      cd ${HOMEDIR}/phoenix-1.48
      echo "Starting Miner: ${1}"
      ${HOMEDIR}/phoenix-1.48/phoenix.py -u http://${MINERUSER}:${MINERPASS}@${MINERSERV} -k phatk VECTORS BFI_INT AGGRESSION=10 FASTLOOP=false WORKSIZE=128 DEVICE=${1}


I dont understand why the fan speed will not set with this script, since I can run this same exact command: DISPLAY=:0 aticonfig --pplib-cmd "set fanspeed 0 75"  and it will set the fan with no problems from a normal terminal session.


GPU 1 will only overclock to around 900,300 and be stable. 
GPU 2 will only overclock to around 930,350 and be stable.


Here is the script I am using for these 2 GPU's:

Code:
#!/bin/bash
# ${1} is used as a variable for the username, password and for the gpu device number.  Ex. mineruser0, minerpass0, Device=0 or mineruser1, minerpass1, Device=1
      HOMEDIR=/home/bitcoin
      MINERSERV=btcguild.com:8332
      MINERUSER=MYMINER${1}
      MINERPASS=MINERPASS

      export AMDAPPSDKROOT=${HOMEDIR}/AMD-APP-SDK-v2.4-lnx64/
      export AMDAPPSDKSAMPLESROOT=${HOMEDIR}/AMD-APP-SDK-v2.4-lnx64/
      export LD_LIBRARY_PATH=${AMDAPPSDKROOT}lib/x86_64:${LD_LIBRARY_PATH}

      #Overclock GPU to 875Mhz
      DISPLAY=:0.1 aticonfig --pplib-cmd "set fanspeed 0 75"
      DISPLAY=:0.2 aticonfig --pplib-cmd "set fanspeed 0 75"
      DISPLAY=:0 aticonfig --od-enable --adapter=all
      DISPLAY=:0 aticonfig --od-setclocks=900,300 --adapter=1
      DISPLAY=:0 aticonfig --od-setclocks=930,350 --adapter=2
      cd ${HOMEDIR}/phoenix-1.48
      echo "Starting Miner: ${1}"
      ${HOMEDIR}/phoenix-1.48/phoenix.py -u http://${MINERUSER}:${MINERPASS}@${MINERSERV} -k phatk VECTORS BFI_INT FASTLOOP=false AGGRESSION=13 WORKSIZE=128 DEVICE=${1}


These cards will run at low temps for hours on end. The highest temp Ive seen has been around 65c.

I  have seen alot of folks running this same setup and are able to get 950,325 out of their Sapphire HD5850's with no stability problems. What are some things I can try to get these cards stable and higher clock speeds?  Do I need to export any display settings?
11  Bitcoin / Mining / Newb question about pool mining vs. Solo on: June 02, 2011, 03:52:07 AM
I have a setup that is running about 1 Ghash/sec right now.  I have a 5870 on its way to push the right to somewhere around 1.4 Ghash/sec.

I am currently mining over at BTCGuild and donating at 2.5% just to take advantage of the features the pool offers.

Is it worthwhile to mine solo?  I have read a few of the threads and wiki's but am still confused.  I calculate that 1.4 Ghash/sec at current difficulty should get around 2 to 2.5 BTC a day average (once you divide out the block you find across the days in the month).  Are those numbers off?

Is anyone solo mining with a comparable hash rate (around 1.4 Ghash/sec)?  If so, what are you averaging at current difficulty?

Thanks for the input.
12  Bitcoin / Mining / Radeon 5870 for $312 -- Need opinions please on: May 31, 2011, 09:28:48 PM
I am contemplating adding a new card into my rig.  Currently I have 3 Sapphire 5850's but I have room for one more.

I found this one for $312 bucks on Amazon:
http://amzn.to/iiOyyZ

I need some opinions from you guys on it.
Does anyone have experience with Visontek cards?  I have never heard of them, and this one appears to be a non-reference card.  How much overclocking will this sucker handle?
13  Bitcoin / Bitcoin Technical Support / help with Bitcoin through a proxy server that requires authentication on: May 25, 2011, 02:18:13 PM
Hello all, I am trying to get my Bitcoin client to work at the office.  OF course the port BitCoin uses is blocked, but I have a proxy on my co-located server that uses authentication I would like to connect Bitcoin through.

I tried starting bitcoin with the following run command:

"C:\Program Files\Bitcoin\bitcoin.exe" -proxy=proxyuser:proxypass@proxyaddy.net:23

but it returns the error "invalid proxy-ip" and doesnt launch.  Is it possible to run bitcoin or bitcoind through this proxy?
