Claymore XPM GPU Miner discussion

[paulthetafy]

has anyone tried this under wine?  I failed - missing opencl.dll which makes sense but I'm not sure how to fix it or whether it can be fixed.  I don't think you can install the windows AMD drivers through wine CLI but i might be wrong

Wine emulator windows and the graphics driver are emulated, unless they revised it where it communicates directly to the Linux driver.

I'm missing Opencl.dll?

Is it necessary to have:
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1

?

At starting miner will tell you about GPU_MAX_ALLOC_PERCENT when necessary. If you don't see any message anything about it (it means that it will show "HashCnt = 512") - everything is ok already.

How and where to put this?
I tried in bat file, at top. but after i now run miner, it shows trt of 0.
Before i did this, trt was at 460-500.What have i done wrong, and how can i fix it??
Running the 10% fee ofc...

Reinstalling drivers did not fix it.
When i start miner, it logs in, and displays hscnt 512, but still trt is o and its not showing any 4c or nothing.
Plz help!

Drivers reinstall wont help.
All Windows gurus fail, so I have to help you.
setx sets variables in Windows registry, permament, not in current local console instance.
Open regedit, go to current_user/enviroment, you will see those GPU variables and delete it from there.
Reboot.

In .bat files use:

f.e.:

set VARIABLE=100

not

setx VARIABLE 100

That way its only local and have no impact at OS all when you close console window.

I hope it helps :-)

Oh, if you want to comment it in .bat file use :: (2 of them) f.e.:

:: set GPU_MAX_ALLOC_PERCENT=100

Thank you very much for your help!
Unfortunaly, i am already installing windows over again!
It sounds locical your solution, but i dont know windows like that, so more easy to reinstall.

Thnx anyway, and happy mining again.

so what's the difference between set and setx?

Thnx guys, up and running again.
Is stock clock and memory the best tuning, or how to tune/OC for optimal result?
Using 2 saphire 7970 and low end cpu, dualcore.
Can i run 3-4 gpus on this setup?When running on stock settings, trt is around 460.
Cpu around 50-60% with 2 gpus.
Thnx in advance, great folks around here!

i'm getting around 450 - 460 with a gigabyte 7950 with 1100 core and 1500 mem at about 1.5v

tl;dr:
set - local variable, dont write it in registry
setx - global variable, writes in registry

That should mean i have a ok result, since geting the same values at stock settings 925core and 1350mem. About 1.074v
It has already found a 10chain, so guessing this is an ok start!

in 5 hours (just after 9pm till 2:35am est) i've made more than my daily average.
my average is calculated on the last 29 days using an i7-3770k overclocked to 4.5ghz
this is using a single gigabyte 7950 overclocked to 1100 core 1500 memory at 1.5v

right now at 2:39am i have 0.40098618 unconfirmed xpm
daily average on the i7 was 0.38xxx

so overclocking the cpu help getting more ?

overclocking always helps, provides the ability to do more calculations per second.
you're not always going to see vast improvements but to me its worth it

unless you're referring directly to this program. overclocking doesnt help at all since it was only using about 11 - 12% of my gpu.
i currently still run primeminer on 6 threads while this program is running.

is it profitable mining XPM with this miner ?

No it is not. DO NOT MINE.

I have 3 280x cards with i5 processor and I get 115k 4ch and on other rig I have also 3 280x card but with amd sempron 145 processor and with -ss 1 I get 75k per card. Is there any way to improve it. Like changing some parameters?

I dont get those who put -nofee 1, really cheap. And you still come here for advice? Thats the people who ruin crypto.

Personal experience,  you need at least a quad core cpu to run properly. Since the miner runs default of 4 threads.

I will try to change threads then.

Even 1-core CPU can handle multiple threads without any problems. The only problem is the speed of such CPU, it will execute threads one by one. So if you have 2-cores CPU you can set -t 2 or -t 4, both settings will have same speed if CPU already loaded completely. What CPU load do you have? If 100%, the problem is that your CPU is too slow to handle 3 280X cards. You can set two cards for XPM mining and use third card for something else.

PS. Actually even latest Celerons can handle up to 4 280X cards in v2.0. May be sempron is even slower, I don't know about AMD CPUs performance much.

Yes, AMD Sempron 145 handles 3 GPU with ss 1(70% load), its just that card get less 4ch/h. Although it handles GPUs, i guess it is still slower and only gives 75k per 280x, when faster processor rig gives 115k.

Comeon, I have rig with old athlon x64 and it cant run even ONE 270X running at full.
Other grig, with my budget A4-4000 which is great for scrypt and other algos will run 3 x 280X at 80-90% gpu use, when i use 4th card all miner instances start to crash aftar some time. And I mean all of that with default -ss. Changing it is even worse.

I have 3 rigs.

1. 3 * 280x, i5-2400 processor(3,1 GHz, 4 cores, 4 threads, 30-40% usage), 8GB ram, win7 64-bit, 13.12 and I get 119k 4ch per card.
2 and 3. 3 * 280x, amd sempron 145 (2,8 GHz, 1 core, 1 thread, 60-70% usage), 2GB ram, win7 64-bit, 13.12 and I get 79k 4ch per card.

My question/point from preavious posts was, bottleneck for rig 2 and 3 is CPU?! Is it still possible to somehow improve without buyng better processor?

[Claymore]

Try to start just one card and see 4ch/h value on it.

Yes, I forgot to mention it previously, I tried it shortly yesterday, result is pretty much the same. At the moment I have actually 2 cards in one rig and 3 card in other and 4ch value is pretty much same for all. So, it is kind of interesting, that amount of GPUs per CPU is not limiting speed but still there is somekind of bottleneck.

I don't have 1-core CPU, so I cannot test it. But 99% the bottleneck is 1-core CPU. If I set affinity to limit miner to 1 core on my CPU it still shows good values, but it can be because opencl kernel use other cores as well.
