I am in the middle of building a second hand pc. I currently have an e6850 processor which, as I am not at the booting up stage to go into bios etc., I do not know how fast it is clocked as I bought this together with mobo and ram as part of a pre-built bundle. I intend to use a x5460 processor and I would like to know if when I put it in will it run at the clock speed it should or the speed the e6850 is set to? (I know they're different socket types but I have a mod which changes 771-775). I thought that xeons don't overclock but I don't know if that means they die when you overclock them or it is physically impossible to do so. I am just being cautious as I don't want to ruin the hardware. Any responses will be warmly received and greatly appreciated, thank you.
