H81 motherboard undervolting?

post #1 of 2
Thread Starter 
Im about to do a build with my weakest over clocking 4670k. Its going to be used as a htpc. It will also be doing video conversions for streaming on the fly running an app called servetome(ios streams) and also Airplayit(driod).

I know its massive ovetkill but I already own the chip and trading down just seems like a hassle. I dnt want to take a loss selling a chip that cannot oc past 4.4.

So I want to clock the chip down to 3.0 and undervolt as much as possible. Will a h81 motherboard allow underclocking/volting? If not does h87?

Currently I have an amd athlon x64 2.5ghz dual core performaning the tasks and it really stresses the system when streaming 80-90% usage. When I tested the streaming from my 4670k at stock I cannot even tell if its using 5% cpu.

You should be able to with the H87, but its price is very close to a Z87 board which allows you to OC the 4670K later down the road if you wish.

At worst, you could just disable Turbo in Bios or enable Power Saving mode.
