I need some help please I'd really appreciate it.

My system is an Acer Aspire PII 300 MHz with MMX. I intend to upgrade the CPU to a Celeron, preferably 466 or 500.

My motherboard information states that the board will support an upgrade to PII 333 MHz or Celeron 266. Of course when I bought this system in the fall of 1998 the fastest processors were 450 MHz I think. It's an Acer board with the INTEL 440EX chipset with AGP support.

My question is this: can I simply upgrade to a Celeron 466 MHz or 500 MHz using a socket 370 to slot 1 adapter plus heatsink and CPU fan? Or is there more involved?

My PII 300 processor has a klamath core with the 66MHz front side bus of course. I believe it runs at 2.8 V although I've also read it is less. I/O voltage is 3.3 V. It's clock multiplier is 4.5 times with an L2 cache of 512 kb.

My concern is do I need to in some way adjust the front bus setting or multiplier? Or will my motherboard just adjust its settings automatically? With a core voltage of 2.8 V do I need to adjust the voltage on the upgrade processor (Celeron 466 MHz or 500)?. Or if I don't do I risk the CPU not running or frying? Would I need an upgraded bios?

This is my first CPU upgrade, so sorry for my ignorance and thanks again for any help it would be much appreciated.

  1. Your motherboard should support the PPGA CPU's with a PPGA-Slot 1 adapter. All the Mendiceno core (PPGA) processors used internal mutlipliers, so that won't be a problem. Just make sure you get the proper Slotket-it has to support the older PPGA processors. Some are switchable (PPGA/FC-PGA), some are PPGA only (the original kind), and some are FC-PGA only (won't work).
