This was posted in this forum for similar problem ( it's about bios settings ) :
https://www.youtube.com/watch?v=H-Ttlv9Sg28
Do you have connected both the 2 4-pin power PCIE connectors right?...i think you did but...
If it doesn't work i would reset cmos reinstall OS, modo driver and then add 1 card, reboot, add another and so on...

I had the same problem and was the "virtual memory" ( i call it page file or swap file.... ).
Try this commad in to powershell if the value is lower than 16256 you didn't set it correctly.
Command:
Get-WMIObject Win32_PageFileSetting
Output example:
PS C:\Users\admin> Get-WMIObject Win32_PageFileSetting
MaximumSize Name Caption
----------- ---- -------
16256 c:\pagefile.sys c:\ 'pagefile.sys'

Re: [ANN] profit switching auto-exchanging pool - middlecoin.com
I don't realy get why payout are low, unexchanged btc of the pool is high , my payout ,like my unexchanged ,are both very low.
If you try to compare different address payout vs unexchanged you can't find a logic....I know thast's middlecoin....anyway that's strange..

Re: [ANN] Official Sexcoin Thread - Now trading at Tagcash.com !!!
How big is your PSU, perhaps it's not delivering enough amperes to the card, and the card notices?
Don't think.....PSU are 1000 for 7970 and 1050 for 280x
I don't know about these two:
"lookup-gap" : "2,2,2",
"gpu-dyninterval" : "7",
About these value i dind't find a lot on google but there is some info in the GPU-README of cgminer.
Looks like that if u set "thread-concurrency" you don't need to set "shaders" , "lookup-gap" , and "worksize" ( if I remember correctly).
Some value like "gpu-dyninterval" are there because when I found a good setting i print it with cgminer and it add a lot of value i don't understand.
ah, nice to know.
What did you use to edit the r9-280x bios? Also VBE7 ?
I changed State #0 and State #6 Engine,MEM,Voltage:
Engine: 930
Mem: 990
Voltage 0.980
but the voltage was to low ( i had no time to test it too mutch) so i had to set it higher with cgminer ( 1020 looks ok , but for 1 card was not enought)
> I builded cgminer my self with AMD-APP-SDK-v2.9-lnx64.tgz ,
could that also be a reason for the good performance?
Don't think because pre-builded cgminer is using an older version I think ( not sure wich one)
-----------------
Later I will try your value (
realy low voltage) .... going down with MEM under Engine (never tried).

I did try your settings, and they resulted in similar power consumption yes - but only 272khash
Now what is your core voltage?
I forgot to say i use the switch g 2 also.
Sometimes some card start at 1/2 expected khash....in that case i have to reboot (maybe voltage...)..
Are you trying with multiple card or just one?
Anyway these are my settings :

Perhaps you have "trained" your cards into high performance?
I have just changed drivers, and flashed an undervolted bios cause 7970 on linux was locked....I flashed also 280x for then discover that cgminer can change 280x voltage (also on linux).
At which (approximate) settings have you had them running in those 6 months, before you reinstalled and readjusted? And which power consumption and temperature?
Well I restart mining on november.. (during summer was killing me) .but i remember i had to use higher memory setting for the same result....Mem to about 1350
Driver ati 13.12 and 13.10 .....I'm using ubuntu but it works also on windows ( i use it just for flash bios)
I builded cgminer my self with AMD-APP-SDK-v2.9-lnx64.tgz , but also the pre-build one could work.
If only I would get even close to 500, it would be fantastic.
Amazing. With that you could even mine for Danish electricity prices :-)
For a while I had Tc = 10240, 11264 on my 7970 and 7850 - because that was the max multiple of shaders that didn't result in kernel errors.
But then very often, both cards would just not start at full power, always one of them hovering at 30khash.
It took me ages to find out this solution, and that it is not a lack of power (I have funny cabling in my old machine):
Tc = 8192, 8192 works perfectly. It's only using 1072MB of the 3GB of my 7970, and I don't understand that - but it's fine.
Can't help mutch about this.But i don't think matter too mutch.It works for me also with other value.
hmmm ... we really need to find out how you are able
to drive your cards up to such high khash for so little
clockspeed = temperature = Watt = electricity costs.
Let's save half of the electricity of the worldwide GPU grid!

Yes are my value (when i see them i did't belive myself).
My rigs are 3x VTX HD 7970 X-Ediction and 4x Sapphire R9 280x Dual-X.
The "U:" not sure what is....it is reported when u are mining and click "G" for modify Video cards setting.
try to put Engine to 900 and Mem to 910, then you go up with Mem 920, then 930 ecc...you should find a spot where you are about 600 Khash/s.
In the photo I' m not using 900 how engine but a little more....900 is just a point I use to start.

I suggest try value like these....I'm pretty happy with them.....temperature and fan are quite and power usage is about 180W x card.
Voltage is ok on my cards but on yours could be different .....you have to try go down with Voltage until it doesn't work anymore.
I suggest using MSI afterburner to find best setting and yhen flash them with atiFlash+VBE7

Re: [ANN] Official Sexcoin Thread - Windows Fix for CLIENTs stuck at 400000!!!
mine2mind112: I rehost the script in < 2 hours, sorry.
np and thank u !!
Re: [ANN] Official Sexcoin Thread - Windows Fix for CLIENTs stuck at 400000!!!
I created an init.d-script for "sexcoind" to launch at Linux startup, 100% works and tested under Debian and Ubuntu. Maybe works/should work on other distributions of Linux.
Script is at:
http://paste.debian.net/72666/
- script must be downloaded an named "sexcoin"
- open the script, edit the settings (line 13 till 25) to fit your setup
- script must be placed in /etc/init.d
- script must be made executable (chmod +x /etc/init.d/sexcoin)
- script must be installed as init service (update-rc.d sexcoin defaults)
- now you can use script with "service sexcoin " to control sexcoind
Hope this helps to strengthen SexCoin network.
Please setup sexcoind nodes, if you run UNIX.

Re: [Work in progess] Burnins Avalon Chip to mining board service
What about something like this http://www.pugetsystems.com/mineral-oil-pc.php for those with many boards?
I think is funny but the point is that this board should make money not eat them
Re: [Work in progess] Burnins Avalon Chip to mining board service
Is possible have the Bill of material ?
I need more information about the ribbon cable.
Another question is why don't use a DB9 connector that is more standard and easy to find?

Re: [Work in progess] Burnins Avalon Chip to mining board service
Hi Burnin since you'll be launching soon the ordering website I'd like to suggest a way to avoid and ordering/preordering/chip-batch matching mess (like what happened with KnC).
All chips come from batches and all batches are time-stamped so once you figure out which group buys are interested in your services, it should be very easy to organize a queue based on batch ordering date. It'll make sense for example if you open orders by turns to specific chip-batches based on ordering date, instead of opening for everyone at once and flooding the website and having to match orders to chip batches afterwards.
For example you first open order books for Zefir Batch 1 from April 16th (assuming this is the earliest one) for like 3 days or so, then you open order books to the next batch based on ordering date, and so on and so forth...
