I tried to removed the other module just to check which module is the problem but it doest work (NO POST), I do the same with the other module in other words one module at time but the result was the same NO POST. I returned back the two modules then POST going on but showing only 256MB. To my knowledge supposed to be work with one module. Please help!!

Upgrading from 64mb card into 128mb or 512mb card. should i remove the component (64mb card) from motherboard? pls help. thanks.

Maybe you are referring to the video card? Or even RAM? If it is RAM you should definitely be using the 512MB (4 X 512) by this time. It is an older board, an ASUS (USA) no longer has a detailed specs webpage for this model. Make sure to check your manual.

PC memory? Im not sure what I can use

Are you sure you have the correct model number? Because that model number should only have 2 Ram Slots located right below the processor slot. I put a picture of the ASUS P4S533-VM motherboard at the bottom of this answer for you to check.

If that is the correct motherboard model number then it takes up to 2GB of PC2700 DDR333 Ram (2 sticks of 1GB PC2700 DDR333 Ram)

Here is a copy of the user manual for your motherboard:

Is it okay i would like to shift 64mb vga to 512mb vga? p4s533-x

Hello, I am the technician that will be assisting you today. My name is Norman-Wynne Damstra.

Welcome to Fixya, Mario Quejada.

Your ASUS p4s533-x mainboard supports graphics cards using the AGP X4 slot. Therefore you may install a graphics card with any memory size so long as it uses the AGP X4 slot interface.

Take care!

The manual for your motherboard states:

• install identical DIMMs in all four sockets OR

• install an identical DIMM pair in DIMM_A1 and DIMM_B1 (yellow

sockets) and another identical DIMM pair in DIMM_A2 and

DIMM_B2 (black sockets)

* Always use identical DDR2 DIMM pairs for dual-channel model. For

optimum compatibility, we recommend that you obtain memory modules
from the same vendor.

Does it have a built-in system beep buzzer? or else you need to connect one. The system beep has a code and will tell you if your video is not connected or your memory is not detected.
Try to make it boot even until the bios screen. Check your video card or your monitor connector. A single beep is a good sign that your motherboard has no problems. hope this helps
