Intel Quad 32bit HDV render under XP

Do you remember how I couldn't come to terms with the fact that - unlike under Vista x64 - under 32bit XP my HDV projects didn't render at full Quad speed, when the project was set to 32bit floating point video? Well, I guess I paid too much attention to what Task Manager was showing (in terms of CPU load in %), and didn't notice that - even though at some 70-80% only - the actual rendering time is not that bad at all! I've just transcoded the rendertest-hdv.veg into m2t (1080/25p, highest quality, with empty audio) in just 1min:22sec, even though the project was set to 32bit (my system is currently QX6700@3.00Ghz, 4GB of RAM).

I wonder what is causing the Taskmanager strange readings...

On my HP Q6600 the Asus MB Bios doesn't have OC features, just a simple BIOS.
There is an option called Machine virtualization on/off (or similar wording). Normally this is set to off.
Do you or anyone know what this setting is? Bios defaults have this setting off. I have left it off and the computer always uses all the cores in Vegas when rendering 8 or 32 bit.

If your rendering 32 bit I would think 70-80 percent cpu usage is pretty good.

4eyes,

I really don't know what the setting you mention is - it might be the Intel Hyper Threading Technology on/off switch.

Those big boys like HP or Dell really seem to be hiding a lot of motherboard tweakability from the end users. Mine is a self-made PC, based around the Asus PW DH Deluxe mobo, and I can set almost everything in the BIOS - the fastes setting I ever used with my QX6700 was 3.6 GHz, but it was running quite hot and induced to much of cooling fans noise. But with some water cooling, people squeeze around 4 GHz on this mobo/CPU combo (the nominal speed of the QX6700 is just 2.66 GHz)

"option called Machine virtualization on/off (or similar wording)" This somewhat of a new tech for high-end server OSs at this time, in fact, although all the big boys talk about it for the big server farms, it is not mainstream yet. Basically and simply put, it helps cpus run large multiples of the the OSs in their own unique "environment", to increase the number of IO tasks but separating them enough from global failure(excluding real major hardware). So, a file management error or task service error does not stop all tasks running on the cpus hardware.
