EDIT (LOTS OF READING LATER)  all seems cool, some updates are below. Still, as this posting that started off just from a speculation, has a general truth in it, I leave it unedited - for now:

TheStilt's magical modded BIOS files

Will this work with a 7950 FX795ATDJC?

Any of these will help you to find the error in your config file:
https://www.google.de/search?q=json+validator

it really depends on the clockspeed.

Have a look at postings #37 and #101


For higher clockspeeds that's not enough to have a stable system, but you can always put it higher from within cgminer.

If you are planning to run in "COOL settings "(C)" then 1.0 V is for sure enough to have a stable system, and still save some energy.

i flashed it at 1v

how do you find that out?

This is what i got right now on cgminer-3.7.2-windows

PC spec

window 8

8gb Ram

7970 XFX

This is the setting i have for example.conf

-I 20 -g 1 -w 200 --thread-concurrency 40960

getting 14-20k KH/s now ...

http://imageshack.com/a/img607/4225/jz7v.png

how much is the consumption at 1v vcore?

any way i can sit at 600-650 KH/s without tweaking with Bois or undervolting?
I'm sorry kind of a noob in this ... what setting can i have on conf file.

First try out settings (A) from posting
#5 https://bitcointalksearch.org/topic/m.4276538 and again
#28 https://bitcointalksearch.org/topic/m.4358354
for a starter.   You can do that without undervolting.

I guess your low performance is mainly because of 1 instead of 2 threads.


Then read everything about undervolting & BIOS flashing, because you want to reduce temperature & power consumption, too.
The table of contents in posting #1 will help you https://bitcointalksearch.org/topic/m.4260763


Finally, it will be easy to max it out to really high hashrates - but that turns out to be actually quite stupid.
Why? Read my standpoint about it there:  http://ecoiner.org/mining-hardware/save-electricity-save-money-undervolting-7970-xfx-self-vbe7-bios-1017

 

Thank you very much. Please consider cryptos instead of fiat: https://bitcointalksearch.org/topic/m.4690974

Happy that it worked out for you in the end!

Can someone help me here please

How do you get it to 700+ KH/s >

Is anyone able to download the stilts bios files? All his dropbox links seem to be broken.

I have not been able to post on this site for a while now due to the site thinking my IP is posting to much.

The stilts bios worked for my revision TDBC. So anyone having the same issue, whatever the stilt did worked. Just download his bios then mod it with VBE7 to undervolt.

Darkoin I promised you $5 if you helped me fix the card so please send me your paypal address.  

To drakoin:

Thank you big time!! You did an awesome job. Because of this thread I bought 2x 7970 XFX and I got it all done in a snap. Right now I will mine for some hours as a thank you. I get some rejections on your mining pool. On my own I don't (or maybe 1-2%).



I used your (C) settings and have put my vddc on 0.925 right now. Will try to lower it later.

Thanks again!!

Can someone confirm its worth reading because it works for my XFX R9 280X BLACK OC DD "TDBD" model and XFX R9 280X DD "TDFD" model?, I'm ready to tip you!

If that happens, there is probably a comma too many / few, or any other syntax error.
If you don't find it, try a json validator like http://jsonlint.com/



If your voltage is locked, you need to flash the vgaBIOS of your card.

Extract the vgaBIOS ("ativwinflash" or "gpu-z") and backup it in a safe place, then (in a copy) lower the voltage with "VBE7" and save your new vgaBIOS to a USB-stick, to boot with, and flash the card with atiflash (how-to-flash is described in download in posting #45 ). Most people then report that they can now vary the voltage.

If you have never done BIOS flashing, it's recommended to read the whole thread, and other info pages about it. It's your own risk.

I suggest to study at least the postings #45, #67, #37 , #56 - and more which is linked from the "table of contents" on page 1

 now above link works....

Anyone
got good 7970 and 7850 settings
for the maxcoin cgminer already?

EDIT: MAXCOIN

* Afterwards, I wrote a longer text about my half sad half fascinating days in the purgatory of maxcoin.

* In the first launch attempt Maxkeiser DDoS'ed bitcointalk - we actually spent time outside BTCT :-)

* The next day they were far from ready with their coin - but forced the birth. Ugly violent angry crazy night. Working through a tunnel is a weird kind of fun. Seeing other people reap profits is really frustrating.  CPU and Nvidia only.  In the end, I bought servertime, whew expensive. But learnt so much in the process, great!  Stratum code was faulty, but cudaminer & #1ghcom got it right.

* During the stormy birth then, I made this collection of BATCH files to call RPC-API functions of the wallet
  (posting #4425 & #4131 - only 5 hours between 300 postings!!)
   Very helpful for newbies, who before only knew the GUI windows wallet, and were going nuts with maxcoind.exe.
   Caldeio over at overclock contributed a superb manual and a whole thread to my idea to make the maxcoind.exe clickable by batch files.

* Difficulty through the roof. Pools collapsed under the load. Very few pools known.
We did a crowdsourcing of known & stable pool servers. Relax.

* The only exchange, corrupted into this coinstart, failed us bitterly. "Orders are queued".
   About a dozen attempts to sell just failed.  Then I had to have a pause for REAL LIFE, not in my power.

   When I came back, and saw the ignored sell orders, and the dropped price ... I stopped my purchased servers.
   Almost made losses in this.  Got no profits for all of my work out.


That's life, you cannot always win.  
Especially not with hard work.

Gained a LOT of experience. For next time.

Come on, Max Pumper, drown your 2nd baby - and start stacycoin.

/sarcasm

WOW WOW WOW.  That makes me proud.

It's soooooo cool what is happening here. I could only afford two Radeon cards so far - so my electricity savings are not even 200 Watts. But by documenting here what I learnt - and passing on this knowledge, it's going into the thousands of Watts now.  We save energy!

Happy happy happy!
