28-01-2004, 10:08 PM
Hi i am thinking about buying some RAM pc100 for my Compaq Deskpro EP with a celeron 500mhz. Intel 810e motherboard i think.

But i see single or double sided.

Whats the difference between these..apart from one havin chips on both sides.

And outta curiosity will double sided work with my comp.

Really its a question whether the single sided RAM will work. with some older PC's it doesn't (eg yours...) I think the only dirfference is that single sided is eaiser and cheeper to make... I dont really know. Check out Compaq's web site, or the manual that came with your comp.

I810e chipset can support 2 double sided PC100 modules totalling 512MB RAM.
Single and Double sided depends on how the memory banks are designed. i810e supports upto 4 banks of 128MB each, meaning if you want to use 256MB PC100 module, it must be double sided (2 banks with 128MB per bank)
If you want to use 128MB PC100 module, it can be single or double sided.

Hope that helps

It depends on speeds and motherboard settins, tho many can vary. Your best bet is to stick with what you have :D

You have 2 slots. Each slot is actually 2 banks (double sided)
You may have to get rid of the 64MB module and install a 256MB double sided memory module
