Question about IBM eServer xSeries 206

1 Answer

Attempting to upgrade xSeries 206 memory from 512 to 2x1Gb. Existing memory is PC2700 300 2.5CL Reg ECC in slot 1 New is PC3200 400 3CL Reg ECC. in slots 1 and 3. 3x3 beeps on bootup and blank screen. Have followed IBM advise and rebooted at least 4 times after upgrade but still 3x3 beep code on startup. According to manual the system should accept the upgrade. What else could I try. New memory is good, no faults.

    The memory is brand new and has a life time warranty. I have tried a single chip in the original slot so that slot is clean. No joy which ever new chip I use in the original slot. The spec of the memory has exactly the same spec as that defined by IBM for the server. The only difference is that the memory is not sourced from IBM but from a server memory specialist in the USA. However the spec is as read from the chip and checking it against IBM specs it should work. I can accept one chip may be faulty but not both. Because I can only access the server a.m. on Mon, Weds and Fri I can do no further checking until tomorrow. However IBM have advised me to boot with all slots empty to zero out the BIOS and try again as that often then re-registers the memory, whatever size is inserted provided it is of the correct spec, which it is. Unless you have other ideas I can try tomorrow that is the route I will attempt. Also, I know no one with with a similar slot config so very much on my own on this one.

this is as a result of memory error. The memory is either not compatible with your computer, or maybe you did not fix the memory well which is not making the computer not see the memory.

Cpu beeps most times if a memory is not present or not compatible with a the CPU.

Use a brush to clean or dust off the memory slot and try again. You can borrow a memory from your friend and test it with our cpu.

But I believe the memory you want to upgrade is not compatible with your CPU.

Good luck.

    Is the previous memory still working with the IBM computer?

    Hi, if the previous memory still works then its not a memory slot problem but the memory itself. I mean the Ram might not be compatible. Or is the CPU locked to only one Ram? Its like the new Ram is not just clicking with your IBM. Its not a problem from either the Ram or IBM, but an incompatibility issue.

    Take care.

Blue screen when trying upgrade memory

If you are adding more RAM to the existing RAM then then new RAM maybe incompatible with the existing RAM. Use RAM that is the same specs as the existing RAM and from the same manufacturer.

Do this model supporsts win xp service pack 2


This unit has a Pentium 4 2GHz single core processor, and does support Windows XP SP2.

The standard memory installed on this unit was 256KB RAM, in order to run XP efficently you will need to upgrade the RAM. I suggest upgrading RAM to the maximum amount allowed of 2 GB RAM.

To upgrade the RAM to 2 GB you will need 2 modules of 1GB PC2100 184 pin DIMM ECC each.

I am looking to upgrade memory on an MSI N1996 Mother Board which has 2x 168 pin slots and 2x 184 pin slots. I wish to know if I can go to 2GB and which memory is best to use, i.e. ECC,...

If your motherboard supports ECC, and you can afford the much-higher cost of ECC RAM, then buying/using ECC is "best".

Note that "buffered" memory is much slower than "unbuffered" memory.

Those beeps mean that your RAM is not functioning. Are you sure you got the right upgrade type. Sometimes it'll fit into socket but won't work because of speed. Or just try reseating the modules.
