In Timo's thread about RAM today, I noticed dmidecode and I got the data for my Dell Dimension 2400 (Celeron CPU) box, which is below. I won this box in a raffle, during February 2005. After I got the box, I got conflicting information, from Crucial.com and from Dell Latin America, regarding the maximum RAM configuration. To be conservative, I bought two 256 MB DIMMS from Crucial.com, early in 2005. Running dmidecode, I got the below information. Questions: (a) Is the maximum capacity of this motherboard 1 GB instead of the 512 MB I thought it was? (b) Is it possible the mainboard capacity is 1 GB, but that the BIOS limits to 512 MB? To add further confusion, I just searched for this model on crucial.com and they are showing 2 GB total capacity. However, they do not allow one to select between the Celeron CPU which I have and a non Celeron CPU and they may have different capacity. TIA! Lanny

You running the latest bios for the system?
According to dell 2GB is the max
http://support.dell.com/support/edocs/systems/dim2400/en/sm_en/specs.htm
Looks like it supports multiple memory speeds, a lot of systems can use more total memory if the memory speed is lower(most often seen this on Supermicro boards anyways)

Probably not. I will ask them if they have a BIOS upgrade for this board.

Nate: On the Dell URL you provided above, I saw the below data. I see the 2 GB Max, but they don't show using 1 GB DIMMS. Not sure where their error is. I will try to get their Tech Support on the phone in the morning and ask about a BIOS upgrade and also if I can install two 512 MB DIMMs or two 1 GB DIMMs. Thank you! Lanny
Memory Architecture DDR SDRAM
Memory connectors two
Memory capacities 128-, 256-, or 512-MB
Minimum memory 128 MB shared DDR SDRAM
NOTE: Between 32 and 64 MB of system memory may be allocated to support graphics, depending on system memory size and other factors.
Maximum memory 2 GB

And also according to Crucial.com 2 GB is the maximum.
Nate: I just sent an email to the lady in Dell Latin America in Austin, TX who has helped us for the past 12 years. Naturally, she is away on vacation until the 12th and the guy who is covering for her is out of the office today. :-) Hopefully he will Forward the email I just sent, to someone who can check this out and give me the correct data. In fairness to Dell Latin America, I found an email from them (28 Feb 2005) where it states the max. is 1 GB, but that I needed to have the same amount of memory in each slot. It had 256 MB, so I bought another 256 MB DIMM at that time, knowing that 1 GB was the maximum RAM capacity. I'd forgotten that..... I asked them to let me know if there's a later BIOS available, with larger RAM capacity and if so, where I get that and the installation instructions. Thanks again, for your time and research!
