>>  Bitcoin Mining Power Could be Put to Better Use

If you want to mine Bitcoin then do it.  If you want to do something else with your computing power then do that.

I'm tired of people telling us our hashing could be doing something better.

I'll be the one to decide how to use my personal resources.  THANK YOU VERY MUCH.

Sure, find the catalyst version that doesn't need them.

You could click on the link in the top post.

Yes, that would be a great new feature.  I wonder why he never thought of that.

Anyway I'm glad your running without burning up your GPU(s).
Good Luck,
Sam

--temp-target <arg> Target temperature when automatically managing fan and GPU speeds (default: 75)
--temp-overheat <arg> Overheat temperature when automatically managing fan and GPU speeds (default: 85)
--temp-cutoff <arg> Temperature where a device will be automatically disabled, one value or comma separated list (default: 95)

As I said I think the temp cutoff requires manual interaction whereas the temp overheat is where it recovers from.

So are you working yet?

OK, in your example above your temp target is 75, your temp overheat is 85 and your temp cutoff is 75.

Your telling CGMiner to target 75 as the temp you want to run and then telling it to react to the temps at 85 and then telling it to cut off the GPU at 75.  So you are basically telling CGMiner to turn your GPU off.

Do this on this 6850 GPU

--auto-gpu --gpu-engine 200-850 --auto-fan --gpu-fan 50-85 --temp-target 75 --temp-overheat 85 --temp-cutoff 95

850 Mhz seems to be the default for this GPU.

75C is the target temp you want to run at. The fan speeds will change to maintain this temp.
85C is the temp that it will start lowering the Engine Clock.
95C is the temp it will completely turn the GPU off to protect it.  And I think it will require manual action to restart it.

What are you doing/not doing now?

To be realistic your not going to be able to set all of your PC's to the same settings.  Different GPU's will need different settings or you will have a HUGE performance deficit for your higher end GPU's.  Even the same GPU's in different PC's will most likely have different settings because every card/GPU chip has it's own unique characteristics.

For your 6850 this is *probably* ok

--auto-gpu --gpu-engine 300-940 --gpu-memclock 300 --auto-fan --gpu-fan 50-85 --temp-target 75 --temp-overheat 85 --temp-cutoff 95

For your 7850

--auto-gpu --gpu-engine 300-960 --gpu-memdiff 150 --auto-fan --gpu-fan 50-85 --temp-target 75 --temp-overheat 85 --temp-cutoff 95

If you don't know what your GPU engines are running at then *before* you set --gpu-engine run with just --auto-gpu and go into CGMiner's GPU screen and see what it is running at by default and use that number for your upper limit.

You can also use this hardware comparison chart to help you optimize each GPU, if you want.

If you set your GPU clock too high it will either go dead and/or get a bunch of hardware error's.

Well if you don't believe me here it is from the CGMiner Primary author.

OK, the only similar hardware I have is my 5770 and here is what I use for it.  Also I have a 5830 which is the first GPU and 5770 which is my 2nd and the 5770 is driving my display

-I 8,d --auto-gpu --gpu-engine 300-960,300-920 --gpu-memclock 250 --auto-fan --gpu-fan 25-85 --temp-target 75 --temp-overheat 85 --temp-cutoff 95

You HAVE to put an Engine Clock RANGE so that CGMiner can clock down to meet the target temp when the fans have done all they can.

Also if you want only one set of clock range's for all your GPU's you can do that, but, you will need to select the highest engine clock of your slowest GPU and then set your low engine clock range to 300 or some low number per what ckolivas said earlier.

It looks like to me that they are selling a 2nd 2Ghs box for $100?!?

If that is true then that is a much better deal that the 300Mhs USB thingy for 2 BTC.

If it is a 2nd box then maybe they have a supply of rejects that don't meet the needed performance and are trying to recoup some of the loss in building them?

No

>> --temp-cutoff <arg> Temperature where a device will be automatically disabled, one value or comma separated list (default: 95)

To me that implies that the GPU is disabled permanently until you take action to re-enable it.

Now the verbiage in your post does imply that it is *trying* to re-enable your GPU, so I don't know why it isn't.

But I would use a reasonable Temp Target around 60C to 75C, Temp Overheat of 85C to 90C and a Temp Cutoff around 95C

>> --temp-overheat <arg> Overheat temperature when automatically managing fan and GPU speeds (default: 85)
>> --temp-target <arg> Target temperature when automatically managing fan and GPU speeds (default: 75)

Why don't you post your CGMiner command line and tell us what GPU's you are using in this rig?  Maybe we can come up with something that works better?

Pools would have to volunteer the information.

Doing research like Mr. Hearne was doing and posting the pools information without their input was prone to a high margin for error and wasn't fair to the pools.

Well I guess there is sometimes variance in how I think about things and how they really work

To me, the reason to balance between several pools at the same time would be to offset bad luck on one pool with the good luck on another.

Also I don't only consider my mining profitability but also the impact on the pool itself.  So when a pool offers both PPS and another payout which lessens the possibility of a loss to the pool I always choose the other payout method.
Sam

It's a great idea.  It isn't related to payout method.  Just mine as many pools at the same time as possible so that good luck on one pool offsets bad luck on a different one so that your reach a neutral average all the time.

Sam

Is he/you referring to the block size policy for each pool?  The fee and block size policy are related so that would be nice for someone to resume.  But make it a separate thread I would think.

Auto Fan and gpu fan with a fan speed range is only one part of temp control.  You still need to set auto gpu with an engine clock range.

And there are plenty of "GPU TEMP" flags in the readme, gpu readme and top post.

These threads are full of the troubles and pitfalls with mixing 7xxx with 5 and 6xxx GPU's.

This guy is having trouble regulating his temperature so I think mixing GPU types is a little above his head at the moment.

Always start with the simplest configuration and get working then and ONLY then start adding complexity.

Basic T/S techniques.

Looks about right to me.  Block from over 24 hours ago has 100 confirmations.  It takes 120 blocks to confirm the previous block to be sure it is safe to release the funds.

You can always become a VIP member and not have to wait for those confirmations.
