I've been searching for the specifications of this motherboard for past few hours, I've recently got this this low-spec PC for short to medium term use (until I can save up for a decent gaming rig in the future), but I also do want to upgrade some components to make it faster and responsive, but I'm struggling finding any concrete info on what this motherboard supports.

The Desktop model is Acer Veritron M420, but I can't find the exact specifications of the motherboard, using CPU-Z and system information I could find:

 

Desktop Model: Acer Veritron M420.

Motherboard: Acer RS780DV

CPU: Athlon II X3 425 (Socket AM3 938)

RAM: Currently has 4GB but supports up to 8GB, already sorted out the ram upgrade, order in progress.

GPU: Radeon 3200 IGP. PSU is 300W so my GPU choices are limited but I'll think about this later, supposedly the motherboard supports PCIE 16X 2.0 but no concrete info on it.

 

These are the main components I am aiming to upgrade slightly. Maybe even the CPU if I can find what max CPU model it supports.

I've attached a CPU-Z Text report.

 

Any help would be appreciated. Thanks.

    Hello,

     

    Could you give me the first ten characters of the desktop serial number (S/N)? Only the first ten.

    The link stated doesn't work.

    Are you sure on P1.SJM7Z.M70?

    I found the P1.SJM7Z.M7Z (Veriton 421G).

    I think it's the 421G, checked how it looks and it looks exactly the same.

    Is it possible to find the exact motherboard model, I just need to know so I can buy the components I need.

    The help is really appreciated, thank you.
