Single beep ids memory issue

I have a problem with my machine. I was getting sporatic memory type issues and decided to swap out the memory. As I did, the first memory board seemed to fry. So thankfully I have a replacement. When I purchased the new memory, I took the old with me - so I think I purchased the correct one.

The mother board manual identifies that I "have 3 slots for 184-pin, 2.5V DDR DIMM with 6 memory banks. You can install PC1600/PC2100 DDR SDRAM modules on the DDR DIMM slots (DDR 1-3)

When I install the new memory 512MB UNB PC400 in slot 1, the machine does not boot. If I intall it to the second slot, the machine boots to XP, but then suddenly will reboot itself.

First, did I purchase the correct memory? Chip id Samsung 548 K4H560838E-TCCC - 512MB UNB PC400.

If yes, then why doesn't the first slot see the memory. I have reseated it numerous times to ensure a 'true' fit.

Thanks in advance.

hi,
if your motherboard states:
>>The mother board manual identifies that I "have 3 slots for 184-pin, 2.5V DDR DIMM with 6 memory banks. You can install PC1600/PC2100 DDR SDRAM modules on the DDR DIMM slots (DDR 1-3)
<<
then it should be you need a BIOS update to run PC400(actually DDR400) RAMs or you need just a new Motherboard that you can put PC400 RAM modules on;
RAM400 means that the modules run on FSB 400 MHz ,and actually the right type of these Modules is PC3200,which are quite new for your current motherboard:

please give us your motherboard's make and model.

This machine is bit old - the mobo is a MSI 645 Ultra(AMI bios, Video NBIDIA Gforce 2MX 100/200, Intel Pent 4 1713MHz). Not sure if I have given all you need.

It is my understanding that if I flash the bios incorrectly, the machine is kaput. True?

>> if I flash the bios incorrectly, the machine is kaput. True? <<< Absolutely ! if not needed, do not flash the bios !

Okay I won't update the bios until we figure out the issue. Thanks.

Forgot to tell you that the mobo is version 1 - if that helps.

nobus

did you check if your ram is compatible?

The Kingston site does not have info on the ver 1 mobo and memory - they have Ultra-C or ver2. Crucial.com identfied the following.

Manufacturer Model Part Number Size Specifications Price (ea.)
MSI (Micro Star) MS-6547 (645 Ultra) CT3264Z335 256MB DDR PC2700 • CL=2.5 • UNBUFFERED • NON-ECC • DDR333 • 2.5V • 32Meg x 64 Check pricing

based on the above - I think I do have the wrong memory. Am I correct?

" 512MB UNB PC400 - Chip id Samsung 548 K4H560838E-TCCC - 512MB UNB PC400"

i would agree it is wrong; maybe you can check that on the samsung site too, to be sure ?

I was feeling rich so I purchased 512MB PC3200 CL3 184 DIMM Kingston. Wow it works. First slot still not working but if I seat into the second, boots and stays alive. Could the first slot have been 'blown' from the orginal memory going bad?

Thanks for hand-holding me through this - nobus.

Now onto the next problem, but is not part of this forum.

Cheers
