T1650 - memory beep codes with RDIMM

Hi Dubbah,

The beep pattern 1-3-2; tells you that the computer encountered a memory problem

Other useful information about the memory:

1. The Dell Precision T1650 system supports up to 32 GB of memory with 64-bit operating system.
2. The memory speed supported is 1333MHz/1600MHz DDR3 memory.
3. Maximum memory speed is tied to processor. 1600 MHz memory will run at a reduced speed of 1333 MHz, when paired with the Intel® Core i3-2120 or Intel® Core i3-2130 processors.
4. 32-bit operating systems can only use maximum 4GB memory address space.

As mentioned you have 4*8GB reg ECC and these are all RDIMMs. This machine architecture is designed to support UDIMMs.  For further clarification on ECC and NONECC configurations; you can follow the grid provided below:

NOTE:
1The total amount of available memory will be less than 4GB. The amount less depends on the actual system configuration. To fully utilize 4GB or more of memory requires a 64-bit enabled processor and 64-bit operating system

The Dell configuration page for the T1650 allows RDIMMs to be selected with Xeon processors - is this a mistake on the Dell page?

I realize that it's been a few months since the last activity on this thread, but it seems that I've made a critical mistake. We've got seven Precision T-1650s that I had planned to upgrade to 32GB each of 1333/ECC. Well, I didn't like the price that I saw on the RAM selector screen at Crucial ($200+ for 8GB*2), so I went out to Newegg. I found some Kingston 8GB sticks and proceeded order 28 of them. Now I'm getting the 1-3-2 beep code. I have RDIMMS instead of UDIMMS. I do have Xeons in each of them, so I would be very interested to know whether the T-1650s can use RDIMMS via some memory channel adjustment, but I didn't see that in the BIOS. Any suggestions that you have would be very much appreciated. I haven't called Newegg back yet, but their support site says that they won't accept any returns for orders of 10 or more of a specific product. I really hope that I don't have to eat the cost on this. Please advise.
