T5400 only using 4GB/8GB ram?

[Chris_476]

Pretty weird issue here folks. I have a Dell precision t5400 with 8 GB of RAM in 1GB sticks. The bios and Ubuntu say 4GB, but bios also shows 8 sticks of 1GB RAM. What could the issue be?

Does the following link present the User Guide for your motherboard?

https://downloads.dell.com/manuals/all-products/esuprt_desktop/esuprt_dell_precision_workstation/precision-t5400_user%27s%20guide_en-us.pdf

Two immediate things:

1) Check that all memory modules are fully and firmly seated.

2) Verify that all memory modules are supported by the motherboard via Page 36 and Page 187 in the User Guide.

The only issue I see would be heat spreaders but I don't think it can detect that? Not sure. I can try and find a bios update though.

try 6GB and see what gives. Remove the last two 1GB sticks

You mean one stick from each set or two from the same set?
