Topic: 3 x 6970 in Windows...Help needed (.5 BTC bounty) [SOLVED] - page 3. (Read 7470 times)

Actually no, all utilities are paid as part of my rental agreement.  I'm doing it for card longevity and reduced heat (there's literally like no space between the cards).  Plus, I have a 4-year in-store warranty on all cards and I think overclocking can void warranties. 

Why did you under-clock them? for electricity savings?

My 3 6970's are currently at about 360 m/hash at 888 core, 750 mem, 95% fan.  Temps are around 70C for the first two cards and 76C for the last card.  Currently using GUIminer and MSI Afterburner.

first off, let me say that b/c i'm a non techie, i bought this 4 computer setup from a mining machine company that went out of business, so if you're wondering why i might be vague on the components/setup its b/c i didn't put it together.

with that said, i have 3 Win7 miners, 1 with 3 Sapphire 6970's, 1 with 3 Powercolor 6970's, 1 with 1 Sapphire and 1 Powercolor 6970.  all are generating in the low 300 Mh/s sometimes high 200 Mh/s with relatively high temps in the 80C's and high fan speeds.  the miners are controlled with AMD Vision Engine Control/Overdrive using GUIminer.  they all feed wirelessly to a Ubuntu server with the Bitcoin wallet which then connects out to my router and internet.

the AMD software's lowest memory clock setting allowed is 1370 Mhz.  i'm clocked at btwn 900-950 depending on the miner. fan speeds are 75-100%, with power control at 0.  temps are in the 80's.


the system is up and running but with high temps, high fan speeds of 80-100%, and lowish Mh/s per card.  i'd like to get them optimized.

Thanks but problems already been solved.

PSU is doing just fine with 3 of them.  I underclock, not overclock.

Problem solved, bounty paid....you are late unfortunately.

bitcoin.conf for Solo Mining. REPLACE BOLD with your own. Pay close attention to RED BOLD for further setup required.
This file needs to go on the Bitcoin(D) server/app location/machine that others will be pointing to.....

Win7 botcoin.conf default location = C:\Users\USER\AppData\Roaming\Bitcoin\


Once this is in place, run your Bitcoin App on your Server and point all miners to it's internal IP address using the previous instructions above.

I have 4 6970's, with guiminer I get 386 mhash. With cgminer I get 420-440 mhash. You definitely don't want the crossfire bridges connected.
And no dummy plugs are needed thats for linux. Are you sure the miner is not set to mine on one gpu, it can auto reset itself sometimes.
 I would start with removing the cards. Put one in run it, install another reboot and so on.
I would also uninstall catalyst. And just install the cc drives without the full catalyst. Make sure its version 1.11 or lower.
If you try cg miner, make sure to use this shortcut to run it, or all your cpu's will be maxed out. Put this phrase into the target of the shortcut C:\Windows\System32\cmd.exe /c  start "cgminer.exe" /affinity 1 "C:\cgminer\cgminer.exe" (assuming cgminer is located in your c:  folder)

Its clearing a driver issue if you are indeed selecting the proper devices in guiminer. It is not a setting that can be changed. Also your power supply is going to be working overtime. I burned up a 1000 watt with 2x 5970's which draw about the same as your setup.
 

The above will work with SOLO or POOL mining.

Do you already have your Bitcoin APP running in SERVER mode (Server=1) in the bitcoin.conf file ?

Before you do anything, make sure you have a proper bitcoin.conf file setup.

Are you planning to run 1 wallet/app for multiple machines to connect to on your private network ? (personal mini-pool type of setup, which is what I do) ?

I run 4 mining rigs pointed at a single wallet/app for SOLO mining.

Clarify a bit and I will help you get setup.

works great.

+1 made the switch a few months ago and will never look back.

No problem

GOT IT ! thanks.

As far as CGMiner, make sure and give it a try. You will LOVE IT.

.5 BTC sent about 10 seconds ago  

BTW, Ill try out the CGMiner sometime soon.

If I could offer up 1 more small, but hopefully relevant piece of advise ? (no charge....unless you think it's worth something...lol)

Ditch GUIMiner and get on the CGMiner train.

I use it on all my Win7 x64 machines and it rocks. It has the ability to use a config file, but I still find it easier to launch it from a BAT file.

1- Create a new TXT file in Windows.

2- Paste in the following (change where needed)


3- Close TXT File, SAVE, RENAME the file something.BAT (have 'hide known file extensions' disabled, or it will remain a TXT file, regardless of extension)

4- Right-Click the BAT file, choose EDIT (opens in Notepad), Make the required changes, adding your POOL, USERNAME, PASSWORD, GPU Clock Speed (replace XXX). CLOSE/SAVE

5- DOWNLOAD the latest CGMiner (2.1.2) for Win32 (no x64 version, doesn't matter, runs fine). Unzip it anywhere you like.
Thread - https://bitcointalksearch.org/topic/official-cgminer-mining-software-thread-for-linuxwinosxmipsarmr-pi-4110-28402  .........  Direct Download Link (From Developer) - http://ck.kolivas.org/apps/cgminer/cgminer-2.1.2-win32.zip

6- CUT/PASTE the something.BAT file into your CGMiner directory and Double-Click it.....VOILA!


The above CMD is set to run MEM @ 300Mhz and your Target Temp with Auto Fan control at 69C, but these values can be changed also.
Regardless of whatever driver, the CMD is also set to run on a single CPU core, rather than 100%, or all 4 cores of your Quad Core, if that's what you have (affinity = quick fix for 100% CPU Bug).

This will automatically control all 3 of your cards and give you 2 mining threads per card (default setting). Once you get your 'feet wet' with it, you can explore more options.
What I provided above is a basic (pretty much what I use exactly) setup for most of my cards, including my quad 6950 Miners (using I=9 Intensity as above).

Give it a try....you WON'T be dissapointed.

CGMiner replaces Overclocking Software, Fan Control and Miner - ALL IN ONE

Glad to see you got it fixed. Although I didn't offer up the advise for the bounty, I will accept it none the less
Thanks.

Bounty goes to BitLane

BitLane, please send me your BTC address and I will send you .5 BTC.  Be advised that I will not be able to send until later today because I need to buy a new network cable.  After you post your address, I will post again after I have sent the .5 BTC. 

I think you got lucky   I was very tired last night and made the dumb mistake of opening 3 tabs but NOT changing the devices from Cayman-0 to Cayman-1 and Cayman-2.

Thanks for the easy fix!

That sounds about right. You should always design for about 80% with PSU so you have some headroom. Have you tried a BIOS update to see if it is just a firmware issue?
