Hello new to forum but not new to either computers over clocking or modding.
Recently had the misfortune of purchasing a New Dell XPS 600 (got a refurb for a really good price) and since my last machine was roughly 2 years old nearly everything needed upgrading hence the reason for buying the dell. I have been building my own systems for last 8 years and not being able to tweak the bios has been getting on my nerves. used cool bits to over clock the video card (7800GTX) OH despite the shortcomings the XPS 600 really is a good solid machine runs dead quite and cool with exception of not getting into the bios it is really a good system. Keep in mind the first thing you do after opening the box is format the hard drive. All the DELL crap / software have absolutely got to go. Reinstall windows and use their driver disk for sound and MB drivers only. Do not use their video card drivers because it will not let you use a HDTV option (found this out the hard way) do not call tech support because they are all a bunch of idiots. Long story short have been researching this for weeks. The XPS 600 can and is overclockable from dell with the EE CPU and not for any other processor. At first I thought a bios update would cure my problem. Found out the EE edition and non EE edition use the same Bios. Now I read this whole thread and everyone seems to agree there is a pin mod for the 6XX series processors to run 1066FSB without an increase in voltage. Great this should solve my problem as I have a Pentium D 3.0 however no one supplied any links to detail this mod??
Well just received a link from a source outside of the forum and although I haven't had time to verify it's content will supply it for others.
Hope this helps anyone who is in my shoes as I was fully prepared to chuck my motherboard and install a third party but everyone seems to agree no one makes a board to fit XPS 600 case.
