Topic: NVIDIA Kepler (K20) from 134MHash/s to 330MHash/s with CUDA - page 4. (Read 73334 times)

Add "-gpugrid=512" or try "-gpugrid=256"

rpcminer-mod-cuda.exe -url="http://api.bitcoin.cz:8332" -user="WORKER" -password="PASS" -gpu -gpugrid=512

Once I start it I get this, any suggestions?

Starting parameters are:

rpcminer-mod-cuda.exe -url="http://api.bitcoin.cz:8332" -user="WORKER" -password="PASS"

cgminer v.2,11,4 sir

Feel free to ask if you have any questions.

hi guys

i have win8 and geforce710m on my laptotp

can someone give me the instructions for make it?

thanks

it s just for experimental purpose

Yes, I was editing the post with my experiments with -gpugrid when you posted. I could get it up to 4096 before the desktop started lagging a little for an increase of ~1 MHash/s. Not worth it in my case, but will probably make a much bigger difference with more powerful cards.

Also, lowering -gpugrid to 256 the hash rate only dropped to ~47 MHashes/s and I could play encoded XviD and X264 content smoothly at full screen, and was even able to join my Wolfenstein: Enemy Territory server and play with my normal maximum settings at 1680x1050 and 125 FPS without a hitch. Hash rate dropped to ~25 MHash/s while playing though.

With poclbm I can reach ~39 MHash/s at those clock settings but at the expense of an extremely laggy desktop. I never use the normal rpcminer-cuda because it almost freezes my desktop no matter what settings I use and always yields lower hash rates than poclbm. Conclusion: rpcminer-mod-cuda increased my hash rate by over 20% while keeping a completely smooth desktop and even allowed me to play my favorite game while still keeping a good enough hash rate for the GTS 450.

I'm running a GTX560(fermi) slightly overclocked. I get around 71-73 MHash. Bitminter client gets around 81-83 MHash. I'm pretty sure I'm missing something.

@Ephebus :

You get better performance if you set -aggression= to a bigger value and -gpugrid also to bigger value. But than you desktop is not smooth. Do you tested also a other miner?

Just tested the program mining solo with my GTS 450 (core and shaders overclocked to 950 MHz/1900 MHz, 1 GB GDDR5 memory underclocked to 900 MHz) on Windows XP 64 and it ran with no problems. I used this command line:

rpcminer-mod-cuda.exe -url=http://127.0.0.1 -user=XXX -password=XXX -gpu -aggression=1 -gpugrid=1024

Got ~48 MHash/s with those settings. I already had CUDA SDK 5.0 installed (both the 32-bit and the 64-bit versions). Only needed to download rpcminer-mod-cuda.exe, libeay32.dll and ssleay32.dll.

EVGA Precision showed the card was using 99% of the GPU (that program only goes as high as 99% if I'm not mistaken), but the desktop was absolutely smooth as if nothing else was using the GPU.

Tried -aggression=5 but that only increased the hash rate by ~0.5 MHash/s and the desktop got laggy (but still usable), so I don't think that's worth it in my case. Same thing with -gpugrid - could increase it up to 4096 before the desktop started lagging a little. Hash rate with -gpugrid=4096 increased by ~1 MHash/s only.

Is its right that you now faster than before? 101->179 MHash/s
With which program you get 101 MHash/s, is it up to date?

460 at 815mhz with -gpugrid=2048 gets 72mhash, around the same as cgminer unfortunately

thanks sir it's working now but my computer gets really slow it is normal? my old hashrate is 101.5mh/s but now it's 179mh/s im using gtx 660ti oc ed.

rpcminer-mod-cuda.exe -url=btcguild.com:8332 -user=xxx -password=xxx -gpugrid=2048 -gputhreads=256 -gpu=0

should work for you.. enjoy..

still not working sir

rpcminer does not use the stratum protocol

use btcguild.com:8332

sorry for being noob when i run the rpcminer cuda exe and then i put this
rpcminer-mod-cuda.exe -stratum1.btcguild.com:3333 -user=xxxxxxx -password=xxxxxxx -gpu -aggression=8
why it always say CURL return value= 7?

The Plan 9 from outer space of scams? 

no, really bad scam try

its my favorit asic scam until now.
So bad that he it has entertainment value  

Thanks for the information. Nobody must pay for a binary of a open source software. If someone will pay than our BTC address can found in the signature. All developer, Tester and and and do it for the community!!!

thanks sir im gonna try this now
