I HAVE A HP PAVILLION, MODEL A720N WITH A DATA BUS SPEED OF 400MHZ AND LISTED MEM SPEC OF PC2700 DIMM 184-PIN 333MHZ MHZ SPEED. I PURCHASED (2) KINGSTON VALUE RAM 1GB PC3200 MEMORY FOR THE CPU. I PUT THE FIRST CHIP IN - FAN KICKS ON HIGH SPEED THEN SLOWS DOWN TO ALLOW BOOT UP. SHUT IT DOWN AND INSTALL 2ND CHIP - TURN POWER ON AND THE FAN RUNS CONTINUOUSLY ON HIGH SPEED - NEVER KICKS DOWN TO LOW SPEED TO ALLOW BOOT UP. ANY IDEAS AS TO WHAT THE PROBLEM IS?
Hi, You have the answer in your question. I have checked the PC specification and you are right, it uses PC2700 memory. Therefore you need to install PC2700 memory. PC3200 memory will be the wrong speed and will not be supported.

the bios might be seeing it but windows might not, the possibility exists that windows is not able to view the full amount of ram installed try this. go to the start menu > accessories > system tools option and look for the system information tool, this will tell you more about the ram installed, note: windows dose on occasion report the wrong amount of ram when their is a 64 bit os installed or their is a 64 bit system
From the information you sent, I can't figure out the exact make & model of your motherboard, but I would guess that it supports a maximum of 2 GB of RAM. So, I would suggst you try to install 2 RAM modules, each of them 1 GB in capacity & see if this works. From my previous experience, most motherboards with only 2 slots for RAM modules support only a maximum of 2 GB RAM total.
start with removing the added ram try starting up, if it doesn\t start up does it beep?
if noting happens remove all the ram, the computer should definitely beep now.
Add only the original memory and try starting up you should get picture.
This seems to be a old problem and if you don\t need assistance in solving it. It would be great if you would share to the world how you fixed your problem so other users can benefit from your experience.
Dell has a habit of using proprietary memory in their machines, if it isn't proprietary you can near guarantee that cheaper memory sticks will not be recognised.
Play safe and use the memory configurators at crucial.com and newegg.com
I bought two DDR2 1gig sticks at crucial yesterday for $50.00 for both with free shipping.
as u have identified the problem, pls take the defective to point of purchase for replacement.
if still a problem than to kingston for replacement. kingston gives life time wty for memory and u are eligible for new replacment.
let me kow if still a problem
