The most I've seen my new i5-750 work is about 66% CPU saturation when viewing the Task manager. This was observed while unpacking archives using a decompression utility (Winrar, 7z, Izac; for example) that support multiple cores.
I've been thinking maybe that I'm undervolting my CPU in the BIOS. I left it at the default value, which seemed lower than most people have theirs set - even for those not overclocking.
I still haven't found anything that tells me what the default voltage is supposed to be.
Anyway, couldn't the voltage keep the CPU from achieving it's maximum potential? Or do you think maybe the multi-core zip utilities aren't intended to saturate the CPU. I know with my old CeleronD, I would hit 99 and 100% CPU when unpacking.
Could the unpacking really be limited by my HDD speed? - a Samsung F1?
I just installed CPU-Z ... hang on, BRB with results.
OK, CPU-Z is pretty damn cool.
The lowest voltage observed was .872
The highest voltage observed was 1.208
I believe these voltages are correct. Intel stepping is controlling the voltage as needed, for power and heat savings.
Pretty cool, you can observe the effects of Intel's Turbo feature. The core speed peaked at 3.20 GHz (nominally a 2.66GHz processor)
Just seems like I should be able to decompress archives much faster if it would use the potential of the CPU, instead of 20-66%.
What gives?
