AFAIK you can't get the 6XXX to run a drastically lower memory. Even if you edit the bios the clocks are hashed, within windows it will BSOD as soon as the driver loads if you alter them. In linux you can change them to whatever you want. It's a gotcha bulilt into the driver by dear old AMD. With cgminer you can use the memdiff paramter to auto adjust the ram speed to be slower, I think 125 or 150 is the limit.
So if you are running your gpu core at 900 mhz, the ram can go as low as 750 or 775.
Topic: 3 x 6970 in Windows...Help needed (.5 BTC bounty) [SOLVED] (Read 7449 times)
would you mind repeating these Win 7 instructions for a solo miner? thanks in advance.
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.....

Hi Bitlane.
Are you sure that now (6.0 client) I have to forward 8333?
I try without and see that the miners are working.

*shrugs* how 'bout just following a guide like this one?
I never followed any of those guides, thus can't vouch for them but what Inaba wrote looks sensible enough.
Every guide boils down to:
(1) setting up the OS itself. That step is usually very easy and boils down to following the installer. Make sure to set up the ssh access here.
(2) installing AMD drivers and SDK, using "aticonfig --initial --adapter=all" to generate a valid X configuration.
(3) setting up your miner of choice and its config file.
(4) enabling automation so that the machine can be run unsupervised.

There is no concept of a share when you're solo mining.
You either have or don't have the correct hash for current difficulty.
In pooled mining, shares are merely being used to measure miners' hash rate, hence their rewards.

thanks Jake.
looks like i have to install Ubuntu on one of my miners whose Win 7 is corrupted. can you point me to the relevant info on how to set this up? i did RTFM from the beginning of this thread but want to make sure i do this right.

the fact that the Accepted and Rejected columns have 0's in them, is this a cause for concern?
Ok, I got it to work. But how do I flash my BIOS to allow for 300 mem clock? I have 3 x 6970. Lowest it's letting me get is around 770 mem. Also, I can't adjust the voltage.
you got me as to how to actually do it but the bios flash is here:

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.

So I tried installing CGminer on my laptop first before I try it on my mining rigs. Two questions:
1.) Is it natural that my computer is trying to tell me that CGminer is a trojan horse?
2.) When I click on the something.BAT file, why does it open a command prompt that immediately closes?
i never got a trojan horse warning.
your .bat file needs modifying. it did that to me also at first.

Uhmmm... you've got it wrong: the Rv03 has only two pre-installed intake fans as opposed to Rv02's three 180mm fans.
Basically, RTFM
Basically, RTFM
Eesthetics mostly, I think.
I don't have a huge garage to fill up with rigs and since I can't totally hide them from sight, I want the rigs to look decent.
The days I enjoyed seeing naked PCBs and wires sticking out of open cases have long been gone, along with my teenage years.
The 69xx cards are running at about 77°C with average 55% fan speed. Acceptable temps and bearable noise levels if you know what you're doing.
The Rv02, with its rotated mobo, seems to be just good enough. Mind you, I've yet to see my first mining-related GPU failure.
I'd never use a traditionally designed case, though, as barring some serious modding the middle cards get no airflow worth mentioning.

would the rv03 be better since it has 3 180mm fans at the bottom?

Conman, there is a reason the new LGA2011 ATX-size boards all sport the additional molex connector.
Those are quite possibly the first consumer-grade boards designed with heavy multi-GPU action on the radar.
A traditional mobo gets only two 12V lines with the 24-pin connector.
The ATX standard defines up to 75W power usage per PCIE slot but the manufacturers never envisioned such a scenario for all the slots.
Two, perhaps even three devices but not a power hungry monster in each and every single PCIE slot.
There have also been reports of the 24-pin connector burning down.
Those pins can carry up to 13 A of juice (the HCS variation) but the el-cheapo phosphor bronze variety maxes out as 8 A.There are two of those so 16 A * 12 V = 192 W total.
With the HCS pins, you're safely at 26*12 = 312 W.
The question stands, however, what levels of electromigration does 300 W of juice subject the thin PCB traces to in 24/7 mode?
I'm betting high and I'm also betting that's what brought your board on its knees.
I went with Gigabyte boards for those double-thickness traces they're boasting about. When I need another board I'll do the research again - perhaps more manufacturers are using thicker PCB traces now.
The gd70 is the favourite because it's the most cost-effective board, not necessarily the best. Also, you're doing (like me) one thing differently than most miners seem to be doing: you're packing the rigs into PC cases and that means no extenders. More specifically, no POWERED extenders. All the juice flowing through the mobo.

so why exactly are u using cases? an open architecture allows more spacing of cards and less chance of overheating right? if you're not going to be moving the rig around why not make it open and save the money on buying a case?
This thread inspired me to fool with cgminer a bit. I used the config info from this thread and fixed it up for my purposes. Wow...I am friggin' impressed.
What I have found, though, is that it doesn't completely throttle to maintain the designated temperature. I ran it on a card that has a fan out and runs hot...~85-95c. I set the temp at 70 expecting the software to throttle the core to run at 70 and it worked for a while, but alas, when I left it for a few hours, it was running hot...
I am a little simple when it comes to command prompt stuff like this. I need my fat-american GUI. How can I verify that it is throttling as it should? I was hesitant to run another monitoring program with it after reading some stuff about ridiculous voltage spikes in some cards from running two sets of clocking tools.

heh Randy, i have a card that has several blades knocked off the 2 fan rotors. don't ask how. is it ok to run it anyway? how would u cool it?
Since you probably can't get warranty service on it with the blades busted, I would probably just replace it/them. Fans are cheap, and it beats a fried card. That MSI TwinFrozr-II 6870 that I was referring to in my post above doesn't seem to overheat with only one of the two fans running, but who knows...it could be cooking the VRAM or something that I can't monitor as easily. It's under warranty still, so I didn't just swap the fan out...figure I can get a card that is less beat to hell by RMA'ing it.

Actually, there is no surefire way except for setting the GPU core speeds to something like "200,400,600,800" in the config file and looking at the actual hash rates and temperatures.
Another route would be setting one of the fans, say at GPU0, to 100% and observing which card is hyperventilating
