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.
a 6ya Technician can help you resolve that issue over the phone in a minute or two.

Remove the 256mb memory and insert the 512mb memory in slot1 and see whether it works. Please note that the memory needs to be in pairs. I think the GX260 is mini tower has two different moles 1) PC3200 compatible with memory - 184 Pin DDR3200 400MHz 2) PC2700 compatible with memory -184 Pin DDR2700 333MHz Please enter the service tag on dell.com and find the manual and the right memory for your PC All the best!
Hi reisrui, yes it is odd. (It's not the first time I have seen this.)
According to you're manual on page 6, under Specifications. The manual say's you can run up to a Max speed of PC3200 400MHz, 1GB in slot one. In slot 2 you can run a Max of 1GB of PC2700 333MHz in slot 2. Every motherboard I have come across that can run two different speeds of memory. The system will reduce the Max speed to the lower MHz memory speed. If you currently are using 512MB PC3200 400MHz in slot 1 & add 1GB of PC3200 400MHz into slot 2 for a total of 1.5GB of memory. The motherboard will ruduce the total memory over all speed to PC2700 333MHz. Motherboards alway run at the lower memory speed if two different speeds are presant.
I can’t be 100% sure of the 1GB of PC3200 400MHz into slot 2, will run at all! Or if it will be reduce down to 333MHz. I am sure you can run 2GB of PC2700 333MHz, 1GB of memory per slot in you're board for a total of 2GB.
If I can help you further, feel free to post. Suggestions & comments welcomed.
Maximum HP/Compaq approved memory is 4 GBIt has to be the same.
• If you are replacing a memory module, put the
new memory module in the same memory slot
from which the old memory was removed.
• If you are adding a memory module, install the
new module into the socket nearest the
preinstalled module, and install additional
modules in the next available sockets
you can upgrade to a max of 2gb on that board. These are your 1gb options: 1GB PC2700 333MHz DDR Memory, 1GB PC2100 266MHz DDR Memory, and 1GB PC3200 400MHz Non-ECC Unbuffered 184-pin DDR DIMM Memory. Install a set of any of these and your off and running.
