Help me underclock my x6 1055t

[gorion]

I'm considering a DIY nas. From what I've read Bay Trail celeron or Sempron 3850 are good enough for these tasks.

I currently have an x6 1055t I want to retire on a m5a97 2.0 mb.

Playing a bit with settings i locked all cores to 800mhz. Power consumption is down to 100w at wall, keeping in mind that I have a 600w psu not very efficient i think i have a real 80w consumption.

What can I do to lower it further?reduce voltage? What about fsb?

I think that a fully underclocked and undervolted 1055t would still run circles around bay trail while not eating that more power (target 2x)

I think if you allow only 800mhz PowerNow! setting it will already lower the voltage too. Not much to gain going even lower on frequency or fsb on that chip I think.

Your want AMD or Intel ?

Stick with a AMD because theres a chance youll get errors or other crummy stuff.

i5 . 4 core beast threads.

Sell that setup and replace power supply.

That would be option #2, but I will get just 100 € at most from mb and cpu, and selling the case and psu is quite an hassle

Oh no, the Thuban! I hated that chip. Good luck man.

Why?
It always served me just fine so far.

Thanks to the other posters, but I did not have any time to try your suggestion yet. I'll let you know how low I can get it.

The Thuban wasn't a bad CPU. It was competitive (IIRC) with the 2500K at stock, for MT FPU workloads. (Of course, it has six FPUs, whereas the 2500K only has four.)

You play it safe Vritualarry ,,,, your an amazing man.. gb

Thats funny, I've got an Thuban X6 that OC's to 3.6 pretty easily.

Its been sitting unused the past couple years as I've been using the work laptop with dock, not much time for gaming.

Was just considering an upgrade since Skylake finallly came out. Even have been looking at picking up a Xeon1231(?), however this thread made me reconsider.
Didn't realize the X6 was so close to 2500, aside from the extra power use. So, now I'm thinking I may as well use what I've got until Zen/Kaby Lake come out and then reassess.

The X6 w/7870 isn't the monster it was back in the day, however with the Samsung 830 its plenty snappy and I think its fine for all the year- 5 year old Steam games I'm looking at on 1080p.

Or, am I missing something?

Try lowering the voltage, it reduces power consumption more than lowering frequency. At the lowest performance state it has a tdp around 55-60W(800mhz and 1-1,225V), and i bet that it can do 800mhz easily with only 0,8V, maybe even with the voltage minimium of the mb.

I have an Athlon 64 2650e AM2 that works only at 0.55V at 800MHz setting. 2.25GHz overclock is at 0.98V.

Its probably not going to get that much lower OP. The platform itself sucks quite a bit of power, the only way you're going to see significantly lower power numbers is with a newer chip and mobo. Yeah also a more efficient PSU would help.

That said the power saving of going from say 100w-30w would likely take a very long time to recoup the cost of a new setup.

Over the years I moved my home server from nehalem i3 530 -> sandy bridge 2400s -> haswell G3220. The power numbers at idle were 67w -> 45w -> 25w. I did mess around with each setup to see if I could lower it any but I didn't manage to make a difference.

100 watts is only about a penny per hour. It's not worth spending money (or time honestly) just to save half a penny an hour.
