1. Every time I change the mem-clock, the hashrate will go up slightly (about 15Kh/s), and then drop back down to where it was (275Kh/s). According to GPU-Z, the speed is staying where I set it, so why is the hashrate going back down???

It's complicated.

Great program, but a FAQ or README would be nice to help me setup Tongue

No point writing one...nobody would ever read it.

lol

Now how's about some help with my problem?

Full post here. Please help. I HAVE read the readme. If you can't help, please feel free to troll me instead.

OK, I've spent all day trying to optimize this thing. I've got a 7950 on a machine with 4GB of system RAM, and I HAVE read the manual.

I'm trying to figure out the best clock speeds as per the example in SCRYPT-README.

1. Every time I change the mem-clock, the hashrate will go up slightly (about 15Kh/s), and then drop back down to where it was (275Kh/s). According to GPU-Z, the speed is staying where I set it, so why is the hashrate going back down???
2. To try and fix the above problem, I stopped using --auto-gpu. Was this the right thing to do? It didn't work anyway.
3. The README says to keep increasing the speed incrementally until the GPU crashes. I've gone as high as 1600 and no crash (no performance increase either). Looking at the mining comparison charts, I can see that not many people have gone above 1500. Should I keep pushing it? Is there anything to be gained?
4. Without OC'ing, I was able to get ~550Kh/s. Should I just be happy with that?

Batch file is

Code:

cgminer.exe -o stratum+tcp://stratum.give-me-ltc.com:3333 -u user.1 -p xxxxx -I 13 --scrypt --auto-fan --gpu-fan 25-80 --temp-cutoff 90

I'm tired and confused, but if you want to abuse me for missing something obvious, then please feel free

Have you tried giving this a shot for the 7k series card?
Consolidated Litecoin Mining Guide for 5xxx, 6xxx, and 7xxx GPUs

I have. I don't think it says anything about the hashrate going up a little, and then dropping back down 5 seconds after overclocking.

Linux since 1997 RedHat 4

Quote from: ?? on ??

The last version of cgminer I was able to compile on OS/X was 2.10.5, since then there has been a change to usbutils.c that has prevented it being compiled.

the error is:

usbutils.c:805: error: redefinition of ‘union semun’

I removed the offending code

and tried to recompile and got

usbutils.c: In function ‘cgminer_usb_lock_bd’:
usbutils.c:908: error: ‘union semun’ has no member named ‘seminfo’
usbutils.c:924: error: ‘union semun’ has no member named ‘seminfo’

so it seems the semun structure on mac osx doesn't include seminfo for some reason.

any ideas?

semun doesn't exist on linux - you have to define it yourself.
I guess the OSX OS devs misunderstood that Tongue

You'd have to come by IRC to help work out how to fix this in OSX - in linux I define it myself as per the requirements - but that fails in OSX coz it is already defined

Maybe in a few hours though I don't have time right now

updated to v3 impressed 2.11.4 was a kick back and ahd to revert to others.

Now using v4 and have 100MH/s improvement on speeds on mining on sha and improvement of 120kh/s on scrypt. Keep up the good work cgminer

-I d,9,9,9

You should set the flags as follows :
-I 9 -d 0 -d 1 -d 2 -d 3

For BTC mining keep the memory to 300 should be fine

I think batcoin's Intensity settings are correct.

I've never seen "-I 9 -d 0 -d 1 -d 2 -d 3" for setting intensity. Does it work for you? But he still wants one GPU set to Dynamic.
Sam

Works perfectly fine why shouldn't it?
According to the readme 9 is fine for a dedicated miner.

I was referring to assigning GPU's individually with the -d 0 thru -d 3. CGMiner uses all GPU's by default. But, hey whatever works for you.

I'm sure intensity of 9 is fine.

Using 3.0.0-windows. Coming from 2.11.4-windows.

Two 5850's, working flawlessly. I don't see any hiccups. No decrease in hash rates and no increase of hash rates.

Thank you, ckolivas.

Edit:

But! my WU:996.7/m-WU:1026/m is crazy high!!! Which is great, I was at WU:741-771/m.

Actually i have spent more than 5 minutes reading it... Thank you.

You missed spending 10 minutes understanding Scrypt-README.

P.S. README helped me to get 600khash/s from 7970

I did that during setup and I tried it again in case anything got knocked around. No joy... Sad

This problem is driving me nuts. I can't figure what it could be.

Thanks for your help and suggestions so far though.

README believe it or not, has faq about this...

In my first post I mistyped the 6790s as 6970s... I am evidently dyslexic. They are, in fact, 6790s...

I tried this and updated the arguments.
./cgminer -o -u -p -o -u -p -o -u -p -I d,9,9,9 -d 0 -d 1 -d 2 -d 3 --auto-fan --gpu-fan 35-85 --auto-gpu --gpu-engine 600-950,600-950,600-950,600-900 --gpu-memclock 800,800,800,300

BUT...

Only one GPU appears to be actually hashing. I have 4 GPUs appear in the UI and they report that they are hashing, but only the first GPU shows a temperature increase to ~75 degrees. The other 3 are at idle temps, yet showing about 25% of hashing power that the first GPU should have. I even tried running with -d 3 only and the relevant card shows as hashing, but a different card shows an increase in temperature. WTF???

Also, shouldn't the -d device arguments correlate to the adapter numbers when I check temp in aticonfig? They don't seem to...

Taken from the README

To configure multiple displays on linux you need to configure your Xorg cleanly
to use them all:

sudo aticonfig --adapter=all -f --initial

I did that during setup and I tried it again in case anything got knocked around. No joy... Sad
