RB2011UiAS-2HnD-IN overclocking stability?

Currently using RB951G-2HnD overclocked to 750MHz to get higher OpenVPN transfer rates, but need more ports so thinking about changing to RB2011UiAS-2HnD-IN, AFAIK it has the same CPU, but I’m not sure about all other stuff… so asking the community is somebody can confirm that RB2011UiAS-2HnD-IN can be overclocked to 750MHz and have no stability issues after that?
