What could go wrong? Putting a CPU in the wrong socket and turning on the machine (LGA775)

post #1 of 4
Thread Starter 
I have an HP Pavilion w5240la that currently runs a Pentium 4 '531' (P) w/HT @3.0 GHz and I want to put a Pentium D in it. It seems that they both are LGA 775 but HP doesn't list the Pentium D as a compatible CPU. So... Can you guys tell me if I can perform the swap without damaging this machine?

BTW the motherboard is an MSI MS-7174.

Thanks in advance thumb.gif

I just checked on msi and the board supports the Pentium Prescott which is the p, then it says it supports the Celeron d, so I think it will support the Pentium d.
back in the 90's I installed a cpu in a board that did not support it and all that happened is it wouldn't boot, the boards speaker just gave a long tone and would not stop until I turned it off, I put the supported cpu back in and it booted fine.

The celeron d was a single core processor.

I doubt you'd hurt the motherboard if you tried. My only concern would be vrms, however the p4 were pretty power hungry.

Lga775 was a great/weird socket. It was around for what seemed forever. You had older p4, pentium d, core 2 duo, and core 2 quads with numerous die shrinks and almost countless chipsets. Compatibility with older motherboards with the newer cpu's weren't very good.


If your looking for a cheap upgrade you might be able to find a core2 duo + motherboard and still use everything else in that computer. Even a sub 2ghz c2d will beat out the better pentium d due to architecture/ heat/ power draw. About $30 if you find a used combo.

Looks like an intel 915 chipset.. Supported CPUs Pentium 4 and Celeron D. Those are some slow and hot single core CPUs.. Pentium D will not work even know it's the same socket size..
