Compaq Presario RAM upgrade

[phlip67]

Hello;

I have had a Compaq Presario 1500 laptop for about 2 years now, and I am quite un-satisfied when it comes to multi-tasking several applications at the same time. Sometimes it is so slow that I cannot minimize a full-screen application to read up on something on the net. I currently only have 256 megs of ram, but I read on the internet that tihs model could have up to 1 gigabyte. This is great, but therein lies my question. The laptop has two ram slots, one of which has been empty since i got the computer. Could I get a gig of ram and still keep the 256y meg stick as an added boost? or is the 1 gig the maximum for both slots?

Well if your laptop supports a maximum of 1gb then that means 512mb per RAM slot.
Here are a few links on Newegg which is the Maximum Memory you could get for your Laptop. This is if you are in USA

if you are tec minded and the presario has a 915 intel chipset just do a pin mod!!

you can put at least 2gb, but read the ram guide in the guides forum first.

Thank you for your replies. i'll be sure to look into them.

@ woody: Thank you for the links. I have been looking at RAM here at canadian retailers, and it's $20 for 512 mb, but it's probably not as good quality as the $25. then again, I don't know much about RAM, and what the difference is between the speeds and whatnot. all i know is that for an additional $15, you can get 677 mhz ram instead of 400mhz or something.

@ insoman my computer is like 5 years old, and I believe the 915g chipset is for desktop PCs (mine is a notebook).

I don't think your Motherboard will support 400mhz or 667mhz according to this link the maximum your Motherboard can support is 1gb of RAM or 512mb per slot at 266mhz - http://www.memorystock.com/memory/CompaqPresario1500Series.html

Try downloading this and go to the Hardware area and look at Memory it will tell you what frequencies your Motherboard can support - http://www.gtopala.com/siw-download.html

But what i linked you might be the max it can support.

 

[phlip67]

alright, thanks for the link.

Downloaded siw, used it, and the situation is sadder than i thought.

.. 133 mhz is the fastest i can go. rofl.

would the lower frequency make it cost less? do they even make 122mhz ram any more?

 

[woody1191]

No i should have said you have to double the number it shows, DDR stands for Double Data Rate - http://en.wikipedia.org/wiki/DDR_SDRAM here is a link to read about it.
Anyway the number it shows you double it and that is your maximum Bus Speed for your RAM. So i did link you the top RAM you could buy in the first place and now that is confirmed.

Your Maximum RAM - DDR 512mb PC2100 @ 266mhz (2 cards Max)

I don't know any Canadian Retailers so just look for what i said.
