Cahnging Pentium 4's

When you say no go : whant do you mean exactly:

Computer 1 bip but image on screen
bios gives you an error message ?
you get a few bips
the computer power on and shut down ?

Probably have some ddr 1 200 / 333 mhz or something and not compatible with the other porcessors (although its a bit far fetch)

No dexter mate I don't get a thing just a blank screen (didn't even turn on) and I think you've answered my query - its all DDR1 RAM - although I think I took some of the other CPU's out of DDR1 machines - but wouldn't swear to that.

Never mind the machine that she gave me to fix up for her was running a 1.1Ghz Celeron and that really old two notch (don't know what that is called) RAM. Hence when I picked up this Optiflex at a local recycle centre and it has been really looked after I just put her HDD and optical in it and the difference was a 1000% increase in speed lol!!

Anyway she'll be pleased with it now as she could not afford a new machine (poorly paid assistant nurse) or go to a tech shop. Plus I just like the challenge with these things as a hobby ad retirement looming he he!!, and the only cost to friends and workmates is any new parts I have to buy   .

Thanks for your help, time and patience you're a gent!

Hiyya both - found out after all that the board was "custom made" for Dell to only support up to a CPU - 1.7Ghz and 1GB PC133 RAM - hence that "i" in front of the 845 chipset which in it's 'unmodified' state will take up to a 3.0Ghz CPU and higher max RAM.


But it's all cleaned up now and running reasonably quickly - apart from putting another board in there which is more than it is probably worth - it gives her a bit more time for her or me to find a better option (or cheaper new machine - can get an eMachine brand i3 1Gb RAM running 7 Premium for $389AUD).

Anyway gotta give you both gold stars as you were both on track eh?
