Are both chips identical ? if so

Take out the ram and replace it one stick at a time in the socket 0 or 1

If both sets of Ram work then check your instruction book on the motherboard and see what is the maximum ram it will take .

Get a copy of Memtest86+ from www.memtest.org
and run it on both chips , that will show if there is any errors on them.

Are you certain they are both the same kind of RAM, that is the correct type? (DDR2 PCC-8500/6400/5300 Non-ECC)

Are you using 2 1GB modules? Are they seated securely?

If you are using 2 modules, try them 1 at a time to see if they both work individually. If one works and the other does not, either it is a bad module or the wrong type.

You may need to update the bios to support 2 Gigs of ram,or one stick of ram ma by no good.You can try the sticks of memory in another PC that supports the type to test them out.

I need vga driver of p4m800 pro-m7


Hello the homepage is here:

http://www.biostar.com.tw/app/en/mb/introduction.php?S_ID=94#dl

But the driver for win 7 is not there.
It will not help to download the xp driver
My advise is to buy a graphic card that supports win 7
The mainboard have an AGP 8X Slot for extenal graphic card

If you are in doubt adding a graphic card
let a expert do it for you.

Good luck

Replacing memory on the P4M800-M7 A motherboard


No. Just make sure that you two RAM modules have the same specifications (speed, clock).
If you don't know about that, then simply insert both RAM modules and start your computer. If Windows loads, then right click on MyComputer and go to properties. If it shows 1.5GB then you are OK.
If the computer fails to start or you hear multiple beeps it means that they are incompatible.
Replace the 512 module and insert the new one and try again.
Always remember to turn off the power and unplug the cable from the power supply before replacing RAM modules.

DDR2's only showing half installed RAM


IF THE SYSTEM SAYS YOU HAVE 1GB RAM THAN YOU HAVE 1 GIG OF RAM, EVEN THOU SOMEONE TOLD YOU YOU HAD 2-512MG=1GB.

HERE IS HOW I SEE WHAT YOU ARE SAYING YOU HAVE 2-DDR-2 1 GIG STICKS THAT MEAN IF 1 IS INSTALLED THAN YOU HAVE 1 GB AND IF YOU COULD GET 2 STICKS WORKING TOGETHER THAN YOU WOULD HAVE 2GB RAM.
1 CHIP SET = 1GB RAM
2 CHIP SET = 2GB RAM

YOU MOTHERBOARD MAY NOT ALLOW THAT MUCH RAM, OR WHAT I MEAN THE BIOS MAKE UP THE AMOUNT OF RAM.

TO RULE OUT ANY BAD CHIP SETS OR GOOD RAM OR BAD RAM.

TAKE THE PEACE OF RAM THAT IS WORKING OUT AND REPLACE IT WITH THE OTHER PEACE AND SEE IF IT WILL RUN.
IF IT WORKS THAN LEAVE THAT ONE IN PLACE AND INSTALL THE SECOND PEACE IN THE SECOND SLOT.
IF BOTH CHIP SET ARE GOOD THAN BOTH SHOULD WORK OKAY TOGETHER.
IF THERE IS A PROBLEM, IT MAYBE SOME DUST IN THE MEMORY LOTS
OR THE SLOT MAYBE DAMAGED.
OR
THE CHIP DESIGN LAYOUT MAYBE THE OPPOSITE SIDE, THIS MAY MEANS THE CHIPS MAY FACE EACH OTHER, OR FACE OUTWARD FROM EACH OTHER.
