Topic: 7970 on slot 1 getting less MH/s any ideas? (Read 3260 times)
config file is easier to make changes IMO.....
Well the card works fine with intensity 9, thanks for the help.
Also, you could get Alot more mh/s
with GPU 1200MHz, Memory 600MHz; -v 1 -w 256 Diablo Kernal, You should hit 710mh/s
But obviously not everyone has a 7970 that can hit 1200core
Where it is possible to change these settings in cgminer? In guiminer i had optimized my 5870's, now running 7970 @ 1180/160 getting average 680 Mh/s, could i squeez more?with GPU 1200MHz, Memory 600MHz; -v 1 -w 256 Diablo Kernal, You should hit 710mh/s

C:\cgminer\cgminer.exe -o http://YOURPOOL:8332 -O YOURUSERNAME:YOURPASSWORD --temp-target 60 --auto-gpu --gpu-engine 800-1200 --gpu-fan 90 -k poclbm -v 1 -w 64 -I 9
In reality, I have all this written to a config file (with multiple pools), but this is how you would type it out.
Tryed. First impressions: have no big difference from cgminer default setting, nor with W64, not with w256, who is more suitable for 7970 ?
CGMiner default settings ARE -k poclbm -v 1 -w 64. I first started off with -k diakgcn -v 2 -w 256, but seemed to be more memory dependent, and didn't like my lower memory clocks.

Thanks. will try it later

You can either add these options into the command line, or you can add them into the config file. Either works.
Can you please post here how it looks in your comand line? Offcorse without any personal inforamtion. Thanks and +1 guaranteed

With CGMiner defaults (-k poclbm, -v 1, -w 64), I get 706 @ 1200/325

Ok, I'll check this out and set it to 9.
I understand that, but they are all on dynamic intensity.
Also, I do set the computer to turn off the monitor after one minute and has speed does not rise.
I have 5 other machines with 5870's, 5970's and 69XX series and this does not occur.
I also use fixed intensity on those machines.
Why would dynamic only affect one gpu ? The other two are also set to dynamic, I did this for my burn in session.
Because even though your Primary (slot 1) GPU isnt plugged into a monitor, It is still being told "You are the desktop" Granted that it's not Displaying/Drawing anything, It still has all that "you are the desktop" information in/on/running through it, I may be wrong, But goahead and plug in a monitor to Any of the other cards, Your not gonna get a desktop. also i have a duo 6870 setup, Slot 1 card hash 3mh/s slower than card 2, Except if i leave, for a day or so, And comeback, They are both at equal average speeds.Also, I do set the computer to turn off the monitor after one minute and has speed does not rise.

I have an extremely heavy assumption that dynamic is the issue, Just (for testings sake) set all the GPU's to intensity 9-10 (NOT ANY HIGHER) or you might get alot of cpu usage, wich can result in Crappy hashrates, I mean heck, Your dynamic may be bouncing into intensity 13, Pegging your CPU to 100%, Killing the hashrates, Reducing the dynamic, dropping CPU, and mh/s. Only to then "re dynamically" go back to intensity >10 because YOU HAVE NO DESKTOP, OR ANY (practical) USAGE ON THE CARD! Crapping everything, REPEAT

*facepalm* TAKE OFF THE DYNAMIC INTENSITY! If you use dynamic, Then CGminer will only use ONE mining thread on the GPU instead of 1-4 threads (My 7950 runs two mining threads)
I'm getting 0.59MH/s per MHz from a 7970 that's also running the Windows desktop. Optimal yield should be 0.6, and I can get that with intensity 11, but it brings the CPU usage bug on Windows. You mentioned using intensity 6, try 9 instead. That's the max I can go without getting extra CPU usage.
Isn't the first card occupied with displaying your Windows Desktop, therfore it hashes less?
Got the asic quality
77% on one 71% and 63%.
still getting 50 less MH/s on just one card.

monitor on 1st card, but I unplug it once the machine is running and I have windows set to turn off display in 1 minute.
using standard cgminer auto intensity, looks like 6 is what cgminer is using for all three.
also, how do people check into measuring ASIC quality ?

Same or different intensity? Also you running a monitor off 1st card?
My 5850s are both on 8x... They hash at the same rate with same settings but one gets 10% more shares completed. I believe this is due to working transitors on the die but not sure. Either way doesn't sound like your problem.
More specs maybe? Whats your affinity on each gpu... etc. Also, are you checking frequencies with gpu-z or msi?
