Hola,

 

So...  I've got two CPUs available to me that will work with my pl5d2-vm mobo:  a celeron D331 and a P4 SL7PN.  The celeron is 2.66Ghz, single core, no HT, 32&64bit.  The P4 SL7PN is 3.2ghz, single core, HT (2 threads), 32 bit.

 

I'm leaning towards the P4 due to the HT and the 2 logical cores. 

 

Thoughts?

 

 

Depends on what add-ons you'll be running on it. Something to consider is that if you don't need extra processing power, there's not a huge reason to get it, especially if it just increases power consumption and heat output. That's just my opinion though.

I disliked the prescotts of years ago. So much power waste and heat.

From my research both CPU's pull nearly the same amount of power at full tilt.

However unRAID rarely runs at full tilt unless you are doing other tasks.

 

If I had a way to underclock the P4 to 2.4 ghz I would use that.

FWIW, you can safely get away with the Celeron without issue.

However in the future, if you wish to create md5sum's of files the extra thread and processing power could be useful.

 

 

I've liked the older P4 C northwoods @ 2.4Ghz. Those were hyperthreaded and ran cool.

The P4 will heat your room.

Thanks for all the input.  I stuck with the celeron processor since it has been working like a charm for the last 6 months.  I don't use the unRAID array for anything other than serving files so the switch didn't make sense in that way either.
