Title: NVIDIA TESLA M2050 - CUDA or OPENGL? + Not getting Mhash as in Wiki? Post by: endriuska on February 03, 2013, 04:08:35 PM Hi,
I'm new to bitcoins, however I already spend few hours researching how it works and what is. I'm doing some testing with 2x NVIDIA TESLA M2050 (yes, I do know that nvidia sucks compared to ATI and I shouldn't expect alot from it), anyway I looked up on wiki and see that I can get 94.5Mhash/s using the poclbm, see below: http://s175432170.onlinehome.us/wiki.png However, I did some research and found out that poclbm is the same as guiminer, Is that correct? So i ran the GUIMiner and selected default/opengl miner, but all i get is 59Mhash/s? - How can I get 95Mhases? any ideas? http://s175432170.onlinehome.us/opengl.png I kept researching I find out that CUDA miner should be used for Nvidia cards, so I found it downloaded it and ran it via GUIMiner, I'm now getting 85Mhash/s, however I don't have an option to select video card? I'm not sure if it runs on one of them or both of them at the same time? Can I run it on 2 video cards? If yes, how? http://s175432170.onlinehome.us/cuda.png Finally, would you recommend anything else to get MAX out of those 2 video cards? different miner? different approach? Any feedback is appreciated. Thanks! Title: Re: NVIDIA TESLA M2050 - CUDA or OPENGL? + Not getting Mhash as in Wiki? Post by: John (John K.) on February 03, 2013, 04:16:30 PM You should add flags to the 'extra flags' section. Try to see past results from: https://bitcointalk.org/index.php?board=42.0
I'm not too knowledgeable about Tesla cards, so sorry I can't help you more on that. Title: Re: NVIDIA TESLA M2050 - CUDA or OPENGL? + Not getting Mhash as in Wiki? Post by: endriuska on February 03, 2013, 05:33:11 PM Thanks this was somewhat helpfull, i tried few flags but didnt help. Also try eguiminer which only gives 80mhz average per 2 cards.
Anyone else has any ideas? Thanks Title: Re: NVIDIA TESLA M2050 - CUDA or OPENGL? + Not getting Mhash as in Wiki? Post by: John (John K.) on February 03, 2013, 05:34:15 PM Try CGminer too. It's the best updated miner for GPU's currently.
Title: Re: NVIDIA TESLA M2050 - CUDA or OPENGL? + Not getting Mhash as in Wiki? Post by: dresdenreader on February 03, 2013, 05:46:00 PM You can always try running RPC miner.
https://bitcointalk.org/?topic=2444.0 You'll want to create a batch file with the following info: rpcminer-cuda -url=http://pit.deepbit.net:8332 -user=USERNAME -password=RPC_PASSWORD -workrefreshms=60000 -gpu=0 -gpu=1 That should run both GPU's at the same time (I think), alternatively you could them up as separate workers (probably the best idea). rpcminer-cuda -url=http://pit.deepbit.net:8332 -user=USERNAME -password=RPC_PASSWORD -workrefreshms=60000 -gpu=0 rpcminer-cuda -url=http://pit.deepbit.net:8332 -user=USERNAME -password=RPC_PASSWORD -workrefreshms=60000 -gpu=1 But if you want to continue using GUI miner, you would point at rpcminer-cuda and use the following flags: -workrefreshms=60000 -gpu=0, Then you would make a new miner and use these flags: -workrefreshms=60000 -gpu=1 Title: Re: NVIDIA TESLA M2050 - CUDA or OPENGL? + Not getting Mhash as in Wiki?

Post by: dresdenreader on February 03, 2013, 05:59:44 PM why do all newbs mine on a ripoff pool? i mean how stupid can they be... Because it takes us newbs a bit of mining here and there to finally figure out what the good pools are. I know when I started I was like, holy shit, there are so many to choose from, where do I go?! Give him time, he will eventually find a decent pool that he likes with a decent payoff. I personally would say that two very noob friendly pools are 50BTC and MtRed. 50BTC still has a pretty decent PPS compared to most other pools, and the instant share credit is something a newb would like because it would be instant gratification.

Thanks Then i tried rpcminer-cuda -url=http://pit.deepbit.net:8332 -user=xxx_1 -password=xxxx -workrefreshms=60000 -gpu=0 -gpu=1 and it would only do 0 Mhas/s.. And I also tried rpcminer-cuda -url=http://pit.deepbit.net:8332 -user=xxx_1 -password=xxxx -workrefreshms=60000 -gpu=1 and it was 0 Mhash/s any ideas? maybe issue wiht gpu1 or it has different id??Thanks Title: Re: NVIDIA TESLA M2050 - CUDA or OPENGL? + Not getting Mhash as in Wiki? Post by: Gabi on February 03, 2013, 07:04:27 PM Idea one: change pool, deepbit has high fees. Idea two: do not mine with nvidia, you spend more in electricity than what you earn...

Post by: endriuska on February 03, 2013, 10:54:40 PM So, anyway, any suggestions how to get max out of those 2 NVIDIA TESLA M2050 video cards?
Thanks Any I switched to MTRed pool(i have no idea which pools are the best, but I just wanted to get max out of my resources and the focus on pools, it's a lot to take in in one day), any way question off topic, I want to use ONE worker for multiple computers, is that ok? is there any downside to it? (the reason is I want to automate it when the PC boots) Note, i using GUIMiner the OpenCL type Thanks again Title: Re: NVIDIA TESLA M2050 - CUDA or OPENGL? + Not getting Mhash as in Wiki? Post by: John (John K.) on February 04, 2013, 10:33:13 AM Using a single worker for multiple PC's are fine, and no downsides at all.
Title: Re: NVIDIA TESLA M2050 - CUDA or OPENGL? + Not getting Mhash as in Wiki? Post by: endriuska on February 04, 2013, 03:38:54 PM Thanks - will do.
Does anyone have experience how to get max out of those 2 video cards? thanks |
