Re: Claymore's ZCash AMD GPU Miner v4.0

What cpu should I buy to improve my solrate?
I have now celeron g1840 and my best rate is with -i 0,
with -i 1 is less and with -i 2 my rig freezes.
Higher "-i" have no impact even if I choose only one card with -di parameter :S
i have rx 480 rx 470 and r7 370

I have observed the same scenario and would also like to know the answer.
Will Pentium help? (I guess no, but maybe latest skylake?)
Will i3 be enough for 6, 7 card rigs, or we have to go i5?

I haven't heard anyone with an i3 complaining about 100% CPU usage, so an i3 is probably ok...i5 for sure. I would stick with haswell socket 1150 chips though so you don't have to spend extra on a board and ram...just drop it in!

My friends has i5 and his rig with rx480 hangs too on -i 2 intensity..

If it hangs, probably due to unstable GPU clocks, voltages etc, and not CPU load. If CPU isn't fast enough, miner just slows down. -i 2 may stress gpu too much.

buying new cpu just for this (run I2 instead of I0) is a bad idea, you never gonna paid you cpu back
better buy 1 gpu more with the same money

I was considering this exactly. Upgrading my rigs to i7 cpus. But the cost when I looked at a couple more vid cards is hardly worth the justification. When you look at price drop and rising diff. It's too uncertain for me to jump.
