FX 8320, how lower in watts can it run?

[NubUser]

So, i want to build a whs 2011 with my fx8320, atm i havê it running with my athlon 5350 that is a quad core 25w.

I havê plex running on it, and some times with múltiple users logged in to the server things get slow (vídeo transcoding, remote desktop, computers file server)

Any one knows how to make it run at lower as possible só it will consume a lot less than 125w + GPU? Like making it consume 25w but still have the advantage of running on 8 cores?

Well, the FX series are all unlocked multiplier, so I would suggest setting the multiplier way down to maybe the 1.6ghz range. Then if the server has decent response under load, turn the voltage down and stress test under prime95 for stability until you find the right voltage setting for that frequency.

Hum i see, i can try that and see how low i can go, do i need GPU to run it? I mean, i havê no use from display at all or GPU rendering after my system is setup, i could save a couple of more watts

The lowest the 8320 will go at idle is 1.4ghz, so that's as low as you could set it. Let's say the CPU @ 4ghz uses the 125w it states for its TDP. Could be more or less, but close enough.

The 125w/4ghz = x/1.4ghz or 43w at load at 1.4ghz with 8 cores. That is the CPU only. GPU, MB, fans, HD's all add power consumption.

It will need a GPU to boot up and still display a connection, even if it's a remote connection.

What about CPU voltage? This FX can havê potencial then on low power server.
Ho too bad i still need GPU to boot the system

 

[getochkn]

Yes, you could get away with lower voltage, which equals less power. You can also usually disable cores too. Maybe bump up the speed but disable some cores. You'll have to play around until you find that it doesn't lag but it's running as low as it can go either by voltage/core speeds/# of cores.

This is exiting, i am going to try this and see how it goês, thx

Thing is - more GHZ equals progressively more power. Dropping down to 1.4ish ghz won't require a direct ratio of power reduction, it would probably pull quite a bit less. I wouldn't disable cores though, the whole point of having more cores is to better handle incoming requests, transcoding for the plex server, etc.
