**LETS SEE YOUR PILEDRIVER OVERCLOCKS - LET ME START WITH 5GHz+!!**

I think perhaps you set your standards too high.
You are reluctant to run at high clocks which you have proven to not be 100% stablle when under high load.

I am of the same mind, many others aren't though.

Perhaps now you may be coming round to realise that those 'stable' 5Ghz clocks may be anything but.
 
Yeah, I could bench at 5ghz but no way could I do 2hrs of encoding like I just did. It'll be interesting to see what my new cooling set up is like when it's finished as I think that's holding me back a bit. Still, I love a challenge. :)

Interesting temps just now from 2hrs of Handbrake encoding. I use RF20 because I want max quality for playing on my projector so each one takes about 90-120 minutes. Anyway, core temps will hit 57degC and CPU socket 59degC doing that yet I could run OCCT for days and core temp wouldn't go over 51degC although CPU socket temp would go over 60degC easily. Strange that in real use the temps are so different. Just goes to show how stess testing is only any use up to a point.

Have you thought that your system might have been throttling under the heavier load? when I first noticed throttling the core clocks/temps were jumping up and down erratically whereas the socket temp was still high. It's feasable that yours was being throttled permanently so the cores weren't getting very hot, the socket temp has a mind of its own it just seems to scale with voltage rather than anything else.

Stress testing is useful full stop if you run the right programs (Prime95 large fft is generally the best) and monitor the system for any strange behaviour.

OCCT records bus and CPU frequencies so you can see if any throttling has been going on.

You'd need to run hotter than those temps I mentioned to get throttling anyway. I never run it with the socket over 65degC and the cores over 60degC.

Looking around the net they don't start throttling until the cores get past 60c.

Your core temps are actually fairly good.
 
That's thanks to the water cooling and the way the AMD chips are good at getting the heat out of the cores to the IHS. Soldered I guess. The main problem is the CPU socket temp which seems to scale more with voltage. A big part of that is the heat from the VRMs because they draw so much power. I think if you can keep them cool, as well as the cores, you can run higher vcore and higher clocks. The better AM3+ boards have bigger heat sinks here (well that's true of all mobos I guess).

In addition to that, even better heat removal from the cores should help too. My plan for the new loop involves a 120.4 'square' (2x2) rad in the lid, with fans blowing down over the mobo, which should improve the loop performance quite a lot AND improve the air flow over the mobo as I can remove the rad that is directly above the VRM heatsink. It's worth doing as it will benefit whatever set up I put in this case in the future, as well as this current one.

Why?

Because power saving, if you are running your PC 24/7 is important, given the cost of electricity. If you run your PC for 4 hrs/day, using lots of power, then that won't be too bad, but 24/7 with elevated power usage - its not worth it.

This is the main reason why I went with Core i7 - performance AND power economy [I leave my PC on 24/7].

Well you aren't going to run extended prime tests at high clocks if you constrain yourself to that degree.

PD's are not Thubans they run at higher reported temps.
I say reported because AMD temps are fiction.

The CPU is not the only part though. I am a SFF PC fan,so things like this have interested me,much longer than for most people running full sized systems.

PC power consumption is dependent on:
1.)GPU
2.)CPU
3.)Efficiency of the motherboard
4.)Form factor of motherboard
5.)Efficiency of the PSU
6.)Efficiency of the monitor
7.)Whether you overvolt
8.)Whether you undervolt
9.)Amount of disk drives
10.)Usage habits

Just going for a more efficient motherboard alone can affect idle figures.

Moreover,other things in the home and usage habits probably are worth considering more than even your PC. Your fridge,lighting or heating efficiency is more important TBH. Even filling your kettle too much will waste money.

If you are running your PC 24/7 at 100% load folding or something I could understand but it is a tiny fraction of all PC owners even for DIY PC builders. Most of the time PCs are not being loaded anywhere near 100% and a lot of people switch off their PC anyway.

The most efficient PC is one switched off when you are not doing anything with it.

However,if we start looking at things,in fact using a games console with a low power consumption monitor and a laptop or tablet will consume less power than most desktops TBH,if you are that worried about power consumption.

TBH,PCs are not an expensive hobby,so just enjoy being an computer enthusiast,while we still can.

Stop making blanket assertions, you just look like a but hurt fanboy doing that.

Excuse me
It is not a blanket statement it is true.
I have been tolerant of you so far do not test my patience further.

Why are you posting in a PD thread anyway when you have no experience of running one ?
