System Crashes with 2G Memory

[Pannadharo]

Am looking for information that can lead to fix for W2KAS when
installing 2G RAM.

Motherboard: Asus A7M266-D
Processor(s) (2): AMD Athalon XP 1800+
DIMM: KVR266X64C25/512

I have been running two KVR266X64C25/512 for about three years on this
server, but when I install two of the same chip W2KAS crashes with a
different STOP message each time, and never in the same stage of
bootup. Sometimes it will make it into the OS and allow me to run an
application, but the moment the application loads the OS crashes to a
reboot.

I tried inserting the /PAE switch in boot.ini, but this has not
corrected the problem.

However, when I remove the two new DIMM's W2KAS boots fine and
operates perfectly. I shut down the server, took out the old DIMM's
and put in the new DIMM's (still only using two chips) and W2KAS boots
fine and operates perfectly. The problem is when I insert all four
chips at once. At first I thought this could have been faulty chips
(all Non-ECC btw) so I bought two more and the problem is the same.

Please help ...

Re: System Crashes with 2G Memory

Supposedly that motherboard supports PC1600 and PC2100 DIMMs. The model you
posted is PC2700. It may work fine by itself but not when mixed with other
PCxxxx's. What are the specs of the original RAM?

BTW.
This is a hardware issue, not a W2KAS issue.

Kingston specs on this particular DIMM is PC2100

However, after doing some rather extensive digging, it appears that
because I am using Non-ECC DIMM's I cannot use four slots (or three
for that matter) of Non-ECC DIMM's (X64) with this motherboard, but
can with X72R (Registered). So it seems that if I want to upgrade to
2G of RAM, Im going to have to do it with 2x1GB Non-ECC chips (or
4x512MB Registered).

Hardware is fine. BIOS is fine.

Thanks for the response(s).
