Thread Starter 
What is a V8+4 power phase design?

Thanks
post #2 of 9
This from the ASRock website in regards to V8+4 power phase!

The advanced V8+4 Power Phase features sturdy components and completely smooth power delivery to the CPU. It offers unmatched overclocking capability and enhanced performance with the lowest temperatures for PC gaming enthusiasts.

yeah iv'e read that but how many power phases is that? ( i'm new to this).
And is the Asrock ext 3 gen 3 a good mobo?. What are some other good mobos in the same price range?

As for an actual answer...

Power phases have to do with the voltage regulation circuitry on your motherboard. As a general rule, the more phases, the cleaner the power delivered to your CPU will be. Also, if I'm not mistaken, the 8+4 means that 8 phases are feeding the CPU and 4 phases are dedicated to the integrated memory controller contained in the processor.

You're both right from my understanding but it's dependent on what processor is being used... the Integrated Memory Controller (IMC) used to be on most northbridges but on most modern processors it's done on the microprocessor, it was moved to the microprocessor itself to help reduce the latency and the cost of the system.

So yes, V8+4 is 8 for the CPU and 4 to the IMC

From my understanding anyways

8+4 will usually indicate 8 for cpu.. 4 to power ram not imc..

however uncore.. like cpu vccsa is powered by alternate phases.. on maximus iv extreme p67... 8 for cpu.. 2 for vccsa, 2 for vccio, 3 for ram slots.. but usually people just say 8+3

You dont' need to be scared, these aren't AMD boards. intel boards are generally better suited for overclocking. ASRocks 8 phases are fine, pretty much same thing as ASUS phases.

That +4 isn't for memory, or maybe asrock does it different? Most Z68/P67 boards don't give more than 2 phases to memory. That +4 is most definitive VCCSA and VCCIO or VGPU power. Like 8+1+2+1 lol ASRock is funny.
