Hi all,

I recently posted a thread about some RAM not working, I emailed the seller and this is their reply:

"You have ordered 8 chip memory and your laptop requires 16 chip memory"

What is the difference between the two (apart from the obvious number!), and how do you tell the two apart, seeing as I ordered a 512mb, 266mhz, PC2100, DDR module to go with/replace the existing 256mb, 266mhz, PC2100, DDR module. Or am I being fed a load of .....? The laptop is a Compaq Presario 2158 if that is any help.

Thanks again, Doug.

I suppose it's possible you have a high density sodimm, I've really only heard of high/low density RAM on desktops though. Also, as far as I know, all laptop RAM has 8 chips (you can't fit really 8 per side on those 1/2 length things).

I don't know how much RAM your laptop supports, I can never find product specifications for any machine that isn't brand new on HPs website.

It could possibly be the high/low density factor, eg-

that would be what is "16chip" memory is, and 8 chip would have 4 longer ones on each side. So that might be the problem you are having is your laptop doesnt support high density chips.

Power Supply, not the place to skimp. If it fails, it usually takes out other components alongside it, and not worth the risk.
New? Dont forget to read the rules.

Both modules look the same, eg have 4 chips on both sides. I think their trying to bul**** their way out of it. The laptop is just your normal run of the mill type so I'm guessing its nothing unusual.

Cheers guys for your help
