Can you put RAM from a celeron processor into a RAM slot of a Pentium processor please help?

Answer 1

RAM has no association with the CPU at all. It is however related to the motherboard. If the ram slots differ than no they won't carry over. Say it was an old motherboard using S-DRAM and the new motherboard uses DDR-2 RAM then no the old RAM cards won't fit in that slot.

If however the old motherboard used DDR-2 and the new motherboard uses DDR-2. The the RAM will carry over just fine.

It must also be noted however that most motherboards have a RAM limit. Whereby if you put in more than it can handle/use it will disregard it as if it was never plugged in. This can actually have some detrimental effects on performance and can cause a machine to not even boot up.
