Hello everyone, I'm currently new here and I've been reading through a lot of the topics relevant to the 7970 however it seems that most people use compilers and codes. I'm not very familiar with any other programs related to mining at this point besides GUIMINER, it's the most simplistic program... If someone can point in the right direction, that would be very helpful. I might be able to provide benchmark results as I've seen many people request(I'm not that familiar with OCing). Currently my Memory Clock is set to 300 and my GPU clock is at 1100> I get about 645 Mhash/s at temps of about 61*, my fan speed is at 70-80% and I find it quite loud. Today I've received my second 7970, but I get about 300 Mhash/s with that card only, does anyone know why? I've installed the AMD 12.4 Driver 2 days ago. Thank you for reading!
My Specs are
i5 2500k
Corsair h100
ASRock Z77 Extreme4 LGA 1155 Motherboard
Corsair XMS3 4 X 4
Kingwin Lazer Platinum LZP-1000 Power Supply
2 Sapphire HD 7970s (currently going to install 2 Accelero's on the 7970s since the reference fans are loud as hell at 60%+)
1 240 GB SSD
1 750 GB HDD
I have a P3 kill a watt power supply meter if anyone needs anything
How much could I make in 1 day if I left my pc mining 24/7 at 1300 Mhash/s? I paid about 380$ for one of the used 7970s and 460 for the other 7970.
Hi
I prefer cgminer, it does take a little learning but is fully featured and works really well on my 7970s
I wrote a fairly easy to follow guide on cgminer with a .bat file here
https://ozcoin.net/content/win7-cgminer-setup-guideI get 700Mhash/s from each of my 7970s
using something like this in my .bat file
cgminer.exe -o
http://us2.ozco.in:8332 -u graet.20 -p p -o
http://eu2.ozco.in:8332 -u graet.20 -p p -I 7 -k poclbm --auto-fan --gpu-engine 1100-1180 --auto-gpu --gpu-vddc 0.88 --gpu-memdiff -150
I find this is also easy for testing, by commenting out my "stable " line with a # i can run an experimental line but easily revert (by moving the # ) to my original line
ie
#cgminer.exe -o
http://us2.ozco.in:8332 -u graet.20 -p p -o
http://eu2.ozco.in:8332 -u graet.20 -p p -I 7 -k poclbm --auto-fan --gpu-engine 1100-1180 --auto-gpu --gpu-vddc 0.88 --gpu-memdiff -150
cgminer.exe -o
http://us2.ozco.in:8332 -u graet.20 -p p -o
http://eu2.ozco.in:8332 -u graet.20 -p p -I 10 -k poclbm --auto-fan --gpu-engine 1100-1150 --auto-gpu --gpu-vddc 0.95 --gpu-memdiff -150
will run the second line
12.4 driver hasnt been reported as awesome, I still use 12.2 and 12.3
<gribble> The expected generation output, at 1300000 Khps, given current difficulty of 1583177.847444 , is 0.825919145389 BTC per day and 0.0344132977246 BTC per hour.
****at current difficulty***** which is increasing 10%ish in about 36hours
hope that's a help, lots to learn, and every setup is different, you will need to do a little testing/tweaking to get best results
good luck with it all
