New RAM stick = system crash

[Narcisse]

Hi, thank you in advance for your help

I have just bought a new 512 MB RAM stick for. The manufacturer is Kingston, model is KTM0055/512.

This is PC133 SDRAM.

My motherboard is a Asus CUV4X. It has 3 RAM slots. Each RAM slot can contain 512 MB max RAM. One slot has 256 MB, one slot has 256 MB, and the new slot contains 512 MB.

Here are the specs of the motherboard concerning the RAM:

DIMM
3.3V
168-pin
Unbuffered

Now the stick I bought is compatible with these standards.

When I put the new stick in the machine, the memory stick reads the correct amount of RAM (1024 MB = 256 + 256 + the new 512)

The BIOS reads "Installed Memory 1024 MB".

But when I try to start Windows, it impossible, even in Safe Mode, it just reboots

What can I do ?

your machine may have a max. My dads pc takes pc133 (its from ~2002) and it has a max of 768mb ram.

Your motherboard will run PC100 and PC133 RAM. Check that all your RAM are the same standard.
