Greets,This is a follow up to a previous question regarding swapping my existing p4 2.26 533 fsb with a p4 3.06 533 fsb. I've got a Dell 4500 whose mother board is based on the intel 845E chipset - it does support hyper threading. The docs for the box only say that options available are up to 2.8 ghz - but that's just what dell offered, and the PC is a year old - maybe there weren't 3.06 chips then? Before I plunk down the cash, I just want to be sure that my board will support the 3.06 - any reason to suspect otherwise? How could I tell for sure? Thanks for any info!Best,sg

According to Intel, as long as the FSB is 533 it will work, heres the specs on the 845e chipset.http://www.intel.com/design/chipsets/845e/...desk+chip_845e&

Thanks for the info. I think my problem comes in when I look to the bios for hyperthreading support - while the chip might work, would it work correctly? How do I find out if the bios supports hyperthreading? I have a feeling "only dell knows" will be the answer.

Only Dell would know for sure, since they have generic motherboards. You probably won't be able to tell 'til you stick the CPU in.In all honesty, HT doesn't make any real difference to many programs you and I would use. And FS certainly doesn't make use of it. :)
