I just got my mining rig up and running tonight. I pointed it a P2Pool to mine LTC. I'm getting a decent hash rate (~500kH/s x 2 7950 cards), but I am seeing a lot of "Stratum from pool 0 requested work restart" in the log -- I mean like half of the entries. I'm also getting about a 30% reject rate.

I have tried reducing intensity but that didn't seem to change much except the hash rate. But I haven't tried yet to tweak any of the other settings. The settings I am using are from another guy that is also running 7950s on scrypt to mine LTC. I could post all the setting here if it would help.

First of all, should I be worried? I don't know enough about GPU mining in general, and stratum in particular, to know if what I am getting is normal.

Second, if it is not normal, can anyone tell me what I need to do to fix it?

Thanks in advance for any help you can give.

BTW, I did try to search this thread for that "requested work restart" phrase, but didn't find much that was illuminating.


I thought I would post an update on this, in case anyone else has the same issue.

I made two change, one of which, or the combination of both, solved the problem. The instructions I was using said to set "failover-only" to true. I changed this to "load-balance" : true. At the same time, I added two alternative/backup pools at WeMineLTC.com. When I restarted CGMiner, the "requested work restarts and rejects dropped almost to zero. My rate of accepted shares nearly tripled. It is interesting to note that CGMiner's load-balancing function is now almost completely ignoring P2Pool in the "rotation" of pools. I am now at ~600kH/s per GPU with single digit rejects.

If anyone else has a similar problem, those are two things to try.

I did a complete reformat and reinstall of my rig with Win XP.  I installed AMD 12.8 (with the bundled OpenCL SDK), but now I have the 100% CPU usage issue.  I understand this is a driver issue, but my question is which driver should I mess with, the AMD video driver or the OpenCL SDK driver?
Thanks in advance.

Tried this?
Q: The CPU usage is high.
A: The ATI drivers after 11.6 have a bug that makes them consume 100% of one
CPU core unnecessarily so downgrade to 11.6. Binding cgminer to one CPU core on
windows can minimise it to 100% (instead of more than one core). Driver version
11.11 on linux and 11.12 on windows appear to have fixed this issue. Note that
later drivers may have an apparent return of high CPU usage. Try
'export GPU_USE_SYNC_OBJECTS=1' on Linux before starting cgminer. You can also
set this variable in windows via a batch file or on the command line before
starting cgminer with 'setx GPU_USE_SYNC_OBJECTS 1'

Now moved to linux (xubuntu 12.04, from persistent usb flashdrive), same version (Kano's build 3.1.1a) but now I cannot control Voltage.

Doesn't work (altering the voltage on Linux) for 6xxx and 7xxx cards. Only solution is a BIOS flash.

oops Sad, any ideas where can I found info about how to do this? (flash the card to lower voltage), so I don't bug this thread?
thanks!

Since from 3.1.1 the ability to mine using stratum through a proxy has been lost, and it was my only way to mine, I can't upgrade. What solutions do I have apart from always staying on 3.1.0?

what is this "brake pedal" you speak of?

had this error on my jally a couple times now, and it never recovers on its own. just exiting cgminer and restarting fixes it though. once on one computer (win7 64), then I moved it to another computer (vista 32) and it happened there too.

any ideas?

on the chance is something overheating in the unit Ive put it in the basement with a 140 mm fan on it. the temps were 44-46 C upstairs in the living room (72 F ambient), and 34 C in the basement (65 F ambient with the 140 mm fan). if that fixes it Ill let ya know.

Hello, I post this because I'm pretty sure i am doing something wrong, no idea what.

I have been using cgminer 3.1.1 under windows perfectly.

Now moved to linux (xubuntu 12.04, from persistent usb flashdrive), same version (Kano's build 3.1.1a) but now I cannot control Voltage.
GPU clock, mem and powertune is OK, but not voltage, whatever I do, it sticks at 1.250V and as a result of this, I am using 100W more of power Sad

My rig is:
3x Sapphire 7950 OC Boost 3G (they are not voltage locked, as I can change it under windows with trixx perfectly in all three cards)
Mother gigabyte 970A-D3, 2 GPUs with 16x risers, 1 with 1x to 16x riser, all powered ones.

fglrx downloaded from repository (last version)

I can mine perfectly with the three cards, and control GPU and MEM clock, just cannot change voltage Sad

any ideas, link, tip, idea of where to look for?.
thanks!

I think that is not so hard to do for developer. I don't know nothing about it so just assume.
For example for gpu fan speed
you take that cgminer measuer top mhas from 245mh to 252mhashes
and fan speed from 3450 to 3500.
so cgminer know that if you have 350mhashes must be a gpu engine arround 850 and it takes a little lower as it is 800
and than if I set gpu fan speed to 95% it lowers gpu engine for 50 and measure mhahseh if drops if doesnt drop than lower again after 15 seconds for 50 again
and measeure mehashes when it drops starts to measure fans speed it lowers for 20 gpu engine now and when reaches fan speed 95% than stops to lower gpu engine if fan speed drops to 90% than rise gpu engine for 20.
The same it is with temperature of GPU only it is much slower... it measure gpu temp and mhases dropping.

Think for yourself
soryy about the post --temp-cutoff 75
it was just for testing purpose to see when cgminer cuts off gpu and if it will starts again when temperature drops.

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

yes it works ok. thank you
but as I said maybe developer will think about more auto setup cgminer which will lower gpu engine with fan settings or temperature settings

cut off doesnt restart gpu

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

it will be good if cgminer can lower gpu engine by default if I setup gpu fan speed for exampe on 90%.
Maybe will be good some more auto-default setup of cgminer withouth so many parameters

I just tested this on my PC at home on radeon 6850
--auto-gpu --gpu-engine 200-960 --auto-fan --gpu-fan 50-85 --temp-target 75 --temp-overheat 85 --temp-cutoff 75
and device recovered to temperature below target, re enabling
Stratum from pool  0 detected new block and I get 0.000
GPU 0:   31 oC 2516RPM  | 0.000/86.27Mh/s  | A:1  R:0  HW:0  U:0.11/m I:5

and that 0.000 stays on 0.000


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.

thanks I will test new settings for now with this old-new settings no PC has shut down.
I just didn't wan't to set gpu's clock range to leave it automatically, I will set and test.

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

Unless you give it a range of engine clock speeds, auto-gpu can only do one thing: Turn it off when it hits 95 degrees. Give it a range of engines for it clock it down.

Yes I belive you is not question of that.
One question can I set gpu clock for example on PC with 6850 and for another pc with 7850 radeon like this?
--auto-gpu --gpu-engine 300-960 --gpu-memclock 250 --auto-fan --gpu-fan 50-85 --temp-target 75 --temp-overheat 85 --temp-cutoff 95

So if I understand even if 6850 doesn't work on gpu-engine 960 it will work on slow range? Or it wil freeze and shuts down?
Or I must sets separatelly for 6850 and 7850?
Because I plan to put in mining two laptops too which have avout 120Mhash and really like to have for all pcs one settings. If you understand me.

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.

https://en.bitcoin.it/wiki/Mining_hardware_comparison

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

os2sam thank you for helping.
I am looking for "universal" for ati 6850 and ati 7770 and for ati 7850
-I d --auto-gpu --auto-fan --gpu-fan 60-80 --temp-overheat 85 --temp-cutoff 95

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.
