Computer not detecting RAM!!!
 

Hi

I have an MS6714 motherboard,
Intel P4, mPGA 478 pin package
Intel 82845GE Graphics Memory Controller Hub

I have just clipped in a DDR RAM 1024MB - this is my only chip in the
system

On booting up, it doesn't load windows XP Professional

The first time it booted up, it gave me an lsass.exe error, but that
has not appeared since the first attempt at booting

I can only get in via safe mode

In safe mode I go to Control PanelSystem, where it tells me I have
only 32MB of RAM

Before buying, I asked the shop to test the RAM & they said it worked
fine

I don't know what to do, or where to go.

:-(

Please help.

Have you checked you have the correct type of memory ?.
Is it fitted correctly ?.
Here`s the specs for that board.

At the 1GB size, in DDR, there are two types of RAM.
The stuff in the right hand column, uses 128Mx4 chips.
Each chip has a 4 bit data interface. Notice how the
list of chipsets that work with that RAM is limited.
There are no Intel chipsets in the list. That stuff is
popular on Ebay, because it is cheap and unbranded.
I did find it is JEDEC approved and the construction
method does appear in a JEDEC document, but Intel
doesn't approve of the stuff.

On some chipsets, the RAM in the right hand column,
is half detected. For example, an Nforce2 chipset
will only detect 512MB of RAM, if you were to use the
RAM in the right hand column.

So I would be checking the type of the RAM. The shop
may have "tested it", but if they used a motherboard
with a KT600 chipset, then the test results don't mean
anything compared to an 845GE motherboard. You want
to buy branded RAM with proper 64Mx8 type chips on it.

This is an example of a Kingston DIMM that uses the
right kind of chips (64Mx8):
