Problems upgrading memory in xSeries 342 (8669-4RX) - 3-beeps beep code
Posted on 2006-11-26
I am trying to upgrade the memory in an IBM xSeries 342, model 8669-4RX. I got it on eBay, and it came in with all four slots filled with 128mb ECC. According to the IBM website, I need pairs of FRU 33L3325, which I have purchased three. I was planning on using a pair of the 512mb and a pair of the 128mb to get to 1.2gb of memory. I took out all four of the 128 modules and, working with the 512mb modules, when I put any two in the motherboard and fire it up, I get the 3-3-3 beep codes ( no memory found ), the MEM error light goes on, and the LED next to each SIMM socket comes on orange.
I have spent some time looking around on IBM's web site to see if there's something I need to do ( jumpers, BIOS, etc) to allow it to see this memory. So far, I haven't found anything except document that tells of a problem with certain Hylix modules.
The only thing I see is that the memory that works is PC100 and the "new" memory is PC133. The BIOS in the server is 1.07. I see that there is a version 1.08 available, but the release notes don't mention anything about memory config issues. Also, according to the web site, it should be able to take 1gb modules. I did get memory with IBM stickers with the correct FRU number.
I need to get the server at least to 1gb of memory for my application. I've tried the memory in various combinations of the slots, and even bought a third piece to see if one of the two was bad. No combination has produced any joy. Do I have to have all four? I think I've tried booting it up with just two of the 128mb modules...
Can you give me advice that will get this memory to work, assuming that the memory is OK? Is there a configuration change I can make to help it see the change in memory? Something in BIOS, jumpers, etc? I've got a lot of experience with various server-class machines, but this is the first xSeries box I've worked on.
