Claymore XPM GPU Miner discussion

[liifer]

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.

What if remove 4 of 6 cards, i.e. leave only two cards? Do they both work properly? In my tests I used up to 4 cards, never tried >4.

I removed 4 cards,one plug in pcie 16x running @ 60k 4ch,another plug in pcie 1x @ 0k 4ch and GPU useage 0%.

Whatever, only the card plug in pcie 16x get work.

Well, now the only option is to reinstall Windows, it helps sometimes, see message above from "gilad215".

Try not setting ...GPU 100 in .bat files
It helps for my rig with low-cost-cpu.

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.

Press "m", what numbers do you see? Also make sure you use Catalyst v13.12, it is very important.

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.

win8.1 13.12 now,still the same.
In order to recognize 6 cards,I modified the driver.
I guess this miner can't run on modified driver.

It works! 6*50k hash speed now!
Sounds like not as profitable as 280x ...

i'm using an i7-3770k and no matter how many cores i add it always uses around 11-12% cpu.
how can i get this puppy to 80% cpu?

current config looks like this
setx GPUMAXALLOCPERCENT 100
del *.bin
NsXpmMiner.exe -o ypool.net -u jollyriffic.1 -p x -di 0 -ss 0 -t 6
pause

or does this not mine on the cpu at the same time? think that might be the difference with primegpu.
if not thats fine, i can run primeminer for that.

I think it uses less the cpu than primegpu (as far as I can tell from the cpu cooler) the gpu usage is much more stable and almost all the time at 100% (far from being the case with the other one).

i started my primeminer so now i'm back to 90% cpu usage and another 4-6% while playing netflix
yes, i mine on my daily pc with one 7950

[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

cryptsy isn't too greedy?

currently i just use btc-e.com
but a few days ago i had them add xpm to mintpal, but doesn't have many votes.

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

[MarcusDe]

I've found 3 blocks (~27 coins), and for all shares I get like 5-7 coins, hurray ypool!
Please add getwork() protocol into miner so we could get paid fair with solo mining.
Getwork() was implemented in old jh* miner already, so it should not be big problem.

[incognitoworker]

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!
