Will P133 SDRAM work with motherboard that says use P100

[deebeetoo]

I have a Dell desktop with 3 slots for RAM cards
There are two already there of 32MB and 64MB.
They are P100 DIMM SDRAM ECC-type

I want to insert a third one of 256MB. Will a P133 work? also will it matter if this new one is non ECC-type?

Some one help please

Yes, PC133 ram will run fine in a PC100 system. Think of that rating relative to cpu speeds. You can always underclock a cpu with no problems, but if you overclock the cpu you can run into problems.

As for the ECC / non-ECC, I wouldn't combine the two types together. But before you replace the memory and put in the non-ECC dimm, check the bios settings. Sometimes there's an ECC setting, most bioses (spelling?) autodetect memory settings so you should be fine.

Usually if you mix differrent types of RAM, ALL THE MEMORY runs at the rate of the slowest RAM module. It is best to match and not mix, if possible. I usually buy ram from "

http://www.crucial.com/",

who sells Micron memory. Often they offer free shipping. RAM sells pretty cheap on the internet right now; don't beleive what some retail stores quotes as a price! I have seen some computer retailers charge like $150.00 for a 256 M RAM upgrade, when it actually costs less than half of that. Some of these sites, like "

http://www.compbroker.com"

will send out price alerts. That way you just wait till the price is right and order it over the net. My advice is shop around for RAM, but buy good quality! Maybe someone can point out a site that rates differrent brands of memory.
