Core i7 not using all cores/HT?

idata — Sun, 17 Oct 2010 00:12:51 GMT

Dell Optiplex 980 with Core i7 860. Fresh install of Window 7 x64. Device manager show 8 processors, CPU-Z shows 4 cores with 8 threads. When I watch the processor graph in Task Manager I only see activity on processor 1, 3, 5 and 7. HyperThreading is turned on in the BIOS but the machine does not appear to be using them. I'll see very small blips when doing something very processor intensive, but for the most part they are at 0%.

How do I utilize these extra "processors" ?

It must not be processor intensive enough or does not support multi-core.

Core not using all go to type in search msconfig boot configuration then advanced options click, you see number of processors click on it, then click on arrow it will show you all processors on your pc.

MSCONFIG set to 8 processors, no change. I am encoding video and it only seems to use 4 "processors" at a time.

What doesn't support HT? The processor? Or the software?

Is there some software I can use to make sure all is well?

There is a free program called CPUz that will show you everything about your CPU .
