Can PC100 memory be used with an P3 800EB?

[MustISO]

I have a new gateway computer using an 800EB processor, there's a PC133 DIMM already in there, would a PC100 DIMM work in this setup.

If you have EB, you'll need 133memory, some PC100 can do 133 but may crash.

You would in a sense be overclocking the PC100 DIMM to run @ 133FSB. Not all PC100 can handle that kind of FSB increase. Try it and see what happens. If you start locking up in random applications, or the PC wont boot, change the cas settings to 3 as a last ditch effort to make it work.

depends, i have tried all my PC-100 ina friends comp, and it does 133(wanted to try it so when i go to a 133 system i wont need more ram) but i know it only works beacuse it is 8ns. My dads 10ns PC-100 stick wont even boot at 133.

I dunno how the Gateway motherboard is set up, but some chipsets allow you to run a 100 MHz memory bus even though the front side bus is 133 MHz.

If that's possible then I'd rather set it up to run my PC-133 memory at 100 than my PC-100 memory at 133, unless it's really good PC-100 memory.

What motherboard do you have?

Many of them, let you run the RAM at lower than the fsb.

One of my sticks of RAM is generic PC-100, and it runs fine at 138mhz. However, I'm probably just very lucky that it works.
