I added 256MG DIMM,H memory module to my new P4. It turns out the computer requires a SIMM module. When I turned on the computer after placing the chipset all I got was a puff of smoke and NO power, except for the green light on the motherboard from the battery. I have never seen or heard of this type of reaction to a memory installation. Did I fry my motherboard or just the power supply. What causes that happen?

Simms run on 5 volts and dimms run on 3.3 volts. Did you remove the memory and then check to see if the power supply came on?

Now that I have thought about it, how did you get the dimm to fit in a simm slot, when the dimm has more pins?

The dimm fit just fine. It certainly didn't work that way. So, do you think I just fried the power supply instead of my motherboard?

It's really a guess to what is bad and what isn't. The only way to know is to have each part checked out.
The only thing you can check without testing would be the fuse in the power supply.

Ah, could be Rambus RIMM in pairs and not DIMM on the P4, DIMM may fit but could destroy the boards memory controller hub and blow traces off the motherboard. Best bet is to take it into a shop and have a diagnostic test run on it.
