Title: Processing power
Post by: AlainGr on June 11, 2013, 03:04:41 am
Peter,

I see in your sig that you have managed to reduce the processor to a mere .76GHZ.

My first guess is that you did it to reduce some noise that could be induced by the CPU ?

I tried to do something similar just to check, but there are so many parameters that I could only reduce it to 1.2GHZ. Not sure about the results, so I am asking what was the aim ?

Regards,

Alain

Alain,

Answer : having the frequency of the processor stable. I can do that now with 1.37GHz just the same (or 0.43 GHz :) :)).

I'm afraid though that this needs the "XXHighEnd PC" to do that (also at above 1.2GHz). It's a trick applied to what I think is a bug in the combination of OS, BIOS and real time overclocking (underclocking). So, no other tricks are needed and all I do is adjusting the ratio (like 32 for 3.2 GHz) and combine it with XXHighEnd XTweaks' Balanced Load. The real bug is XXHighEnd of course but Bill couldn't know all. Or Intel.

Notice that the 1.2GHz is an OS limit, but *maybe* a BIOS limit or combination. So, you probably managed all right to be under that, but something just prevents it. Same like my ("XXHighEnd PC") real time possibilities; this prooves that software can (un)do it.

And for "processing power", even at 0.43GHz all still easily works and cpu usage is 1% at 32/705.6 playback. True, FLAC conversion takes somewhat longer but nothing to worry about (maybe 10 seconds for an album). And notice that the 0.43GHz is per processor physical core; per logical core (Hyperthreaded) it is 0.215GHz. This times 12 of course were it for 12 FLAC tracks to convert in parallel.

Peter
