I have a celeron 500 cpu rated at 66mhz Bus frequency and am trying to install a celeron 750 cpu which also has 66Mhz Bus frequency.The mother board (Elite P6BAT -A+)is capable of supporting the cpu upgrade. When i swap the cpu's over the system does not boot up.
Do i need to clear CMOS Memory before the inserting the new CPU? I have manualy changed the Bus frequeny but to no avail.
I used to have the Elite P6BXT-A+ * (Ver 1.3) with first a Celeron 400MHz Socket 370 and then a Slot1 PentiumIII; because these CPUs were continually being improved a Bios upgrade was needed to use the faster versions.
Are you saying that windows will not start up or that the machine is pretty much a dead lump?, i.e. lights are on but no-one is home.
If the latter as I suspect then a number of things spring to mind. provided that you have not got your sums wrong and have rediculously overclocked it by mistake. (I'm not throwing stones in glass houses here as I've done it myself),
If you have the speed set too slow all that should happen is that it will runn slow, thats all.
First thing to do is pop the old cpu back in and see if it all works. then ask yourself if the new cpu is a known working unit. next, be sure that the cpu fan is plugged into the right place. some boards will not let the machine boot if no power is being drawn by the fan. Next might seem simple, but you have been monkeying around with the guts, so check the seasting of other components like memory and graphics card.
White TruckMan. When i say it will not boot up It does not even get to the initial screen where it shows memory ands Cpu. status etc and asks to press DELETE to enter setup screen. There is a boot up noise as if it is trying to boot up and no lights.
All works fine with old cpu and new cpu is in working order.
