Hello all,

I have found this motherboard which seems to be missing a voltage regulator where the CPU is - see picture.

What should I expect from this board in terms of voltage available for the CPU? 5V only? And would it be easy to "upgrade" it to 3.3V?

From this thread I see there is a TIP31C as a regulator - but I also see many other components missing. Problems with QDI v4p895p3/smt V5.0

Any inputs?

Thank you!

I'm not sure what's the reason why the motherboard manufacturer hasn't populated the VRM electronics in this board revision.
Later board revisions have it and support 3.3V CPUs.
