7970 Question :D

[Jude Austin]

You probably need to restart the machine you are on.

Also check to make sure you don't have a cgminer.conf file in your cgminer directory.

Did you set the proper shader count for your card?

Intensity 13
memory clock at 1500
Engine clock at 1100
Powertune 0%
ACtivitiy 61%

pushing 580kh/s

What's wrong here that im only using 61% and how can i make it push more?

Now you need to start overclocking with the ratio.

Press G > C > E and enter 1150

then

Press G > C > M and enter 1575

Let it sit for a few, if your hash rate is bouncing around, adjust engine speed in 1mhz increments until it goes steady again.

Then post results.

[previse]

With 1150/1575 clocks i'm steady at 602 Kh/s - My working config is --scrypt -- shaders 2048 --intensity 13 --worksize 128 -g 2

I still think it should be higher; no?

You can keep going.

Go to 1175/1600.

Eventually it will crash.

[Jude Austin]

Shit, are you mining Litecoins or Bitcoins?

If Bitcoins then I have a config you can use.

Sorry.

How are you pulling over 700 when for the life of me i cant get past 615. With 1175/1600 i get 615. after that i'm sort of SoL, 61% activity, 0 powertune now

[ks3rv3rg]

I'm gonna be switching to litecoins but i'd like to know what the best settings would be for me to mine the most?

Right now with
1100 Core
1500 Clock

I'm running 650 Kh/s

worksize 256
vectors 1
aggression 20
threads_per_gpu 1
sharethreads 32
lookup_gap 2
gpu_thread_concurrency 24000

That's my current litecoin.conf in reaper as well.

Any suggestions? Thanks!

Are you sure you're using the proper thread concurrency?  I have the 7950s and their max concurrency is 24000.  Although they run better closer to 16xxx.  You could also try changing the lookupgap to 1.  Also, when you mine litecoin(or any scrypt) and you're using cgminer you need to insert:

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1

Before the rest of your code.  For example, on my 7950s this is my LTC mining setup:

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
title CG_MINER_420
color 02
cgminer.exe --scrypt -o stratum+tcp://us.wemineltc.com:80 -u USER -p PASS --lookup-gap 2 --gpu-fan 100 --intensity 18 --worksize 256 --gpu-engine 950,900,850 --gpu-memclock 1500,1500,1250 --thread-concurrency 16128
@pause
This is fairly optimized for my system after lots of trial and error.

[ks3rv3rg]

So basically that means I can achieve ~550/600 kh/s with the 7950s. Mining LTC/BTC or my current fav TRC.

[Jude Austin]

It takes a lot of tweaking.

We will get there, be patient.

And hardware is a big deal.

The results I seen may not be the same depending on system specs.

Unlike Bitcoin when mining Litecoins there is a lot more being used.

[Jude Austin]

For future reference here is my config file for Bitcoin, these settings are not system dependent.

previse, one thing to notice about Judes setup here is that he didn't set concurrency or shaders. The cgminer guys say that depending on the circumstances, the concurrency can change while mining so its best to leave it out.  Also, if you set shaders and concurrency at the same time the concurrency will cancel out the shaders command and make it pointless.  You can reference the cgminer git readme for that info as well.

This is my Bitcoin mining config.

So no shaders need to be set.

But you are correct about the concurrency, always just set shader count.

Bump up memory another 25.

Essentially keep going up with memory.

Litecoin is memory intensive.

You are mining Litecoins with memory clock.

[zif33rs]

Do you use these?

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1

[previse]

I've tried and its not moving. maybe 1kh/s - it's only using 62% of the GPU - Is there a reason for this?
0% powertune as well

I really am getting frusturated

[previse]

Do you use these?

setx GPU_MAX_ALLOC_PERCENT 100

Yes in my batch file

[Jude Austin]

Don't get frustrated.

Once you have increased memory and don't see a result start adjust engine speed, I would start going down a little bit on engine.

Anytime i touch engine clocks the kh/s go down. Could you look over my settings tell me how they look?

Also powertune 0 or 20?
lastly: why is activity only 62%

thanks

[ks3rv3rg]

Yeah, every problem that you're having, at least a few of us and probably most of us have experienced.  So, no need to get frustrated, plenty of help for you.  Try turning your gpu clock WAY down, to like 900/1000 with your gpu memclock at the max you've been able to run with stability.

Post your config again.

I'll be home soon and if you have TeamViewer I could essentially do it all for you.

It would save you some time and frustration.
