I noticed that whenever I use teamviewer to monitor remotely, the hash rate falls on remote computer. Remote computer has AMD Cempron 145, 7990 card, 4GB RAM. My resolution settings on miner are minimum.
Did anybody noticed hash rate fall with teamviewer?
Whenever I disconnect from remote computer, rate starts raise again.

how much difference in hashrate? anything using the GPU to display graphics is going to consume some resources, but I wouldn't expect it to be more than 1-2%.

it wouldnt affect hashrate at all, i dont think.

If you are GPU mining then Teamviewer does lower the hash rate while using it - it's normal. Just make sure you log out correctly. It's the same as using a monitor while mining - hence the headless rig & ssh.

I confirm that teamviewer lowers your hashrate.
In my specific case it went down to ~650 from ~750khash/s.

Login, do your stuff and _logout_! ;)

Actually, all remote desktop lower the hashrate.. :)

I've noticed an increase in hash rate of up to 140(from 450 to 590) in my 6950.. havnt checked on my r9 290's

Logmein uses a mirror driver and the GPU does writes to it, I suspect the same holds true for teamviewer so it would lower rates.

Thank you all.
Well, it looks like it falls from ~1200 to around 1000, which is around 20%. I did not tested specifically, but it looks like that. This is not happening when TeamViewer just loaded (it is always loaded), but when I actually use it. It is strange, and probably is just some coincidence.

I notice roughly a 10% drop on GPU0 when I use logmein.

Theoretically, it should make no difference to your hashrate, unless you are bandwidth-limited during your teamviewer session. If you are GPU mining alt-coins, however, there is a reasonable chance you will be diverting rendering resources away to your teamviewer session, that might affect your Scrypt hash-rate.

Yeah it doesn't effect ASIC mining but does effect Scrypt GPUs

In my point of view I effects hashrate because of  teamviewer could change screen settings for stable connection. That's why you should use just little bit and close the software.


Also I really need remote pc temperature software. I would like to check my gpu temperature with my iphone? Who knows about it ?

If TeamViewer is like LogMeIn, it usually disables Aero, which kills performance in Windows - your CPU is drawing the screen rather than the GPU.

That's toally normal, GPU have to use some hash power to make a visualization instead of minning.

Which is better ?

Aero Disable ?
Aero Enable ?

I disabled Aero becase I don't  want to  windows uses gpu..

Hi, ehh this is such an old thread lol, but i would like to know if you solved your TViewer prob.  as i am having same issue.. i have i figured out

that if i have both sessions open "server and client" that hashing is good. but when i close tha client and go sleep shutdown my "client" pc.. (mining rig always on with screen monitor off) the hashing gets lower from 28 mh/s to 16 mh/s almost 50% hashing lost.. i wake up and open "client" team viewer on my pc, and hashing get to normal again 28 mh/s

:) hopé find the solution.
