Memory Configurations for Precision T3500

Hi there,

I ordered this 8GB kit:

8GB kit (4GBx2) DDR3L-1600 Unbuffered NON-ECC 512Meg x 64  (CT7347695)


I currently have 4GB of RAM arranged as 4x1GB.


This page from Dell suggests that I need to install either 12 GB (3x4GB) or 24 GB (6x4GB) and that it's nots possible to install the 8 GB kit that you recommended.



Could you tell me if it is possible to install the 8GB kit please?


many thanks,

Hello Tim,


Thank you for your comment.


I sent you an email a few days ago about this but I wanted to reply to your forum post too. 


We would always recommend checking the official installation instructions when installing memory.  You are correct in saying this system needs a specific installation setup.  You would not be able to install just 8GB it would have to be a 12GB set up for this model.


All the parts listed on the link you provided are guaranteed to be compatible.


If you do have any other questions at all, please don’t hesitate to ask.

Re: Memory Configurations for Precision T3500

Current working RAM stick configuration:  4GB, 4GB, 4GB - 2GB, 2GB, 2GB


I have extended the RAM on my Dell T3500 twice, and I now have 18GB of RAM installed.

First, I extended the Dell-supplied (2) 2GB sticks made by Hynix with (1) 2GB stick made by Crucial for a total of 6GB.

The original 2 sticks were in the 1st two of the white-tabbed slots, and I just added the 3rd stick in 3rd white-tabbed slot.

I ran the memory that way for about 6 years.

Recently, I added (3) 4GB sticks by Hynix.

I initially tried just putting the (3) new 4GB sticks in the black-tabbed slots, leaving the (3) old 2GB sticks where they had been, but the BIOS didn't like that configuration.

So I shifted the (3) old 2GB sticks to the black-tabbed slots, and I put the (3) new 4GB sticks into the white-tabbed slots (for a total of 18GB).

Using 2 different sizes of RAM sticks isn't mentioned as a workable configuration, but Windows sees all 18GB of memory, and all 18GB checks out perfectly when I run MemTest86.
