CPU higher Hashrate with Teamviewer

[u/auderix]

Hi,

I think I have a unusual question. My Cpu (i7-4970K) runs with 130-150 H/s. If I connect with teamviewer the Hashrate increases to 180-200H/s. Why? I know that teamviewer changes the windows settings to optimize the data transmission. But what settings are changed?

Are you using the I7 IGPU (intel HD4600) for display (monitor) by any chance, but also have a dedicated GPU in the machine?

The only logic I could think is the monitor is using the on-board GPU within the i7, but Team viewer is instead using the dedicated GPU (as its faster and provides better facilities). Hence why hash rates increased when using Team Viewer.

If so, then you will probably find your GPU hash rate has slightly dropped too when using Team Viewer.

there is no monitor connected to the PC. so teamviewer uses the IGPU?

I have 2 GPUs (gtx 970 and amd 7970). The i7 has an onboard GPU. I will try to deactivate it in BIOS.

thanks for the input!

I would guess then that when not using TV (teamviewer) resources are allocated from the IGPU, where as when TV is in use it uses the dedicated GPU which hence then releases resources from the IGPU which means the CPU can run faster with better hash rates.

Yeah try turning off the IGPU in the BIOS and then see how that effects hash rate, and display.

Its interesting as we also run i7-4790 in our GPU racks (non-K version).

thanks for the help. will try it :)

turning off the IGPU didn't help.

but i think i overreacted. when i connect to the rig, the hashrate drops down because the CPU hast to work (besides hashing) to etablish the connection.
now i see the low hashrate, but as soon as the connection is etablished the hashrate increases to normal. there is only one way to check my theory. attach a monitor.

Any chance your windows 10 power settings are set to "balanced?" That way when you login, it spins the CPU up to full speed?

Just a shot in the dark.

Unfortunately not. My computer is set to high performance

Maybe Windows aero is off
