I have an old computer which am gonna put Ubuntu on if I can get the extra RAM for it. The RAM module inside it already is PC100 and the only other RAM I can find nearest to it is PC133.

Is it possible for me to run both together or is this just epic fail?



p.s. maybe this doesn't belong in this forum.

I think 133 could run... at 100 mhz... worst thing that can happen is that you render the motherboard uselss ;)

If you take a picture of the PC100 in it where I can read the sticker on the front of it I can give you a good guess if your plan will work.

Also, PC100 : http://www.memorysuppliers.com/sdrampcforde1.html
Or did you mean you couldn't find any around the house ?

hyper_ch is right...the 133 will step down to/run at 100...but you need to have the 100 module in the first slot for the board to recognize it needs to run the RAM at the slower speed...

Usually PC100 and PC133 will run OK together. The 133Mhz stick will only run at 100Mhz speed however.

Keep an eye on what you're spending on getting older type RAM. Sometimes the obsolete types can be so expensive that it's worth upgrading the whole mobo and using cheaper, faster RAM.

the RAM's only about 10 so it's okay, but thanks.

@ sharks: will do.
