Affinity problem

[dorion]

I'm running a Phenom II 965 on a Gigabyte GA-MA770-DS3(no official support for my CPU) and Windows 7 64-bit. My problem is something really sucks on my computer. I submit as evidence screenshots of CloneDVD encoding The World is not Enough.

CloneDVD with all 4 cores.

The source and destination of the videos was to my NAS over gigabit.

Is the problem my AM2+ motherboard which is as far as I can discover the only non-OEM AM3 compatible motherboard known to man, or do AMDs(and Intels?) have this problem no matter what?

I don't think CloneDVD is multi-threaded. I did a google search and many people are complaining about the same issue. Have you tried Handbrake instead?

 

[DrMrLordX]

you tried a source/destination other than the NAS with similar results?

edit: richie seems to have nailed it

The problem is less that CloneDVD isn't multithreaded, more that CloneDVD and other similar single threaded apps don't get scheduled to a single core and instead get scheduled across all four cores in such a way that I'm using 25% of my processor with worse performance.

Use handbrake, it will use all cores and greatly reduce the encoding time.
