I'm just learning this stuff, so bear w/ me, but I have what might be an easy question...

I have an old Win95 Pent II computer that is rated at 66mhz (according to HP), and by mistake, when I was upgrading the memory, I put in a PC100 SDRAM...and it still worked.

I've since taken it out, but I'm wondering....does PC100 work on some or all 66mhz systems? Is there potental damage I could do if I left it in?

Any guidelines anyone could offer would be appreciated.

In theory, it is possible to put a high clocked rate of RAM in a lower clocked RAM slot. But you will only get the clocked speed of the bus(slot). So in your case you put a 100MHz chip in a 66MHz slot, you are only getting the 66MHz speed. I have done this when Im upgrading a system, b/c I found good deals on RAM and instead of shelling out all of the money up front, it gets speaded out through the upgrade of the system.

Now I would not put lower clocked RAM in a higher clocked slot. It should be safe, but I dont do this. (Ex. 100MHz Chip -> 166MHz Slot)

There is no potental damage to the system by having a higher clocked RAM in a lower clocked RAM. But it would be a waste of money to buy the higher clocked RAM if you have any plans on upgrading b/c you will only get the output of the bus. Hope that this helps.
