Shuttle barebones pc xs35v3 wont post with 4 GB of RAM

[SteveKo]

Hello,
The Shuttle XS35V3 doesn't POST with 4 GB of RAM (2x2GB). It POST only if 2GB of RAM is installed in the slot closest to a motherboard. How to use all 4 GB of memory?

If you could post some more system specs such as make and model of motherboard, make and model of RAM, PSU, and everything else that would be helpful. Also if you could identify any beeps or system POST codes that would also be helpful.
