Hyperthreading, XP Home and FAH

aaronrkelly · 29-November-04, 08:14 AM

Im getting ready to buy a newer processor - looking at the 3.0 GHz Prescott 800 MHz FSB HT CPU at the egg for $185. I have just a few questions.

I have built a few HT systems but always put XP Pro on them - this is my home PC and it still has XP Home and is stable with no issus so I dont want to reformat just to install Pro. I know HT shows as two processors in XP Pro and thus you can assign each processor a task (such as running two copies of FAH). I have checked Microcraps website and they list XP Home as supporting HyperThreading. What does this mean? Will it show 2 processors (I dont think this is the case since Home doesnt support multiple processors) or does it mean it will just simply run on the OS? Second if it doesnt list two processors can I still assign two copies of FAH to the processor or must I have XP Pro for that functionality as well. Third - if I cant assign two instances of FAH but instead run one will it only take 50% CPU usage as it would in Pro or will it take 100% since the OS doesnt support the HT CPUs.

I have googles this with no answers - anyone running HT on XP Home out there???/
