Just a query. I use onboard graphics as I dont have enough hdmi ports on my monitor for my gpu rig and my raspi setup. So use vga for gpu rig.

So would using the onboard graphics effect my hashrate when cpu mining?

IGPUs use system memory so it could affect CPU mining of memory hard algorithms. Reduce the resolution
or use console mode to minimize the impact.

or use console mode to minimize the impact.

If system memory is a concern, you'd also want to get into the BIOS and reduce the amount of system RAM allocated for the integrated graphics, if that hasn't already been set to the minimum.

It isn't so much the amount of system memory available but that the IGPU competes with the miner for cache space.

See this is what i was thinking. Currently have an i3-7300T and getting 63hs mining XMR. It doesnt use anymore electricity mining with it so may aswell use it to do something.

But i wouldve thought it would have a better hashrate than it currently has.
