NVIDIA TESLA M2050 - CUDA or OPENGL? + Not getting Mhash as in Wiki?

[endriuska]

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:


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?






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?



Finally, would you recommend anything else to get MAX out of those 2 video cards? different miner? different approach?

Any feedback is appreciated.

Thanks!

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.

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

Try CGminer too. It's the best updated miner for GPU's currently.

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

why do all newbs mine on a ripoff pool? i mean how stupid can they be...

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 this was helpfull, I did try to run 2 files:
rpcminer-cuda -url=http://pit.deepbit.net:8332 -user=xxx_1 -password=xxxx -workrefreshms=60000 -gpu=0
rpcminer-cuda -url=http://pit.deepbit.net:8332 -user=xxx_2 -password=xxxx -workrefreshms=60000 -gpu=1






The first one was working at 75mhash/s, then I ran the other one, the first was slowed down to 15~, and the second one was 0 - any idea why would it be so? maybe it's not picking the gpu properly? 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

Idea one: change pool, deepbit has high fees. Idea two: do not mine with nvidia, you spend more in electricity than what you earn...

if someone has to choose and has a bit of inteligence, he wont pick the pool with the highest fees

Out of curiosity, which pool to do you use?

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

[John (John K.)]

Using a single worker for multiple PC's are fine, and no downsides at all.

[endriuska]

Thanks - will do.

Does anyone have experience how to get max out of those 2 video cards? thanks
