Graphics card overclock

[ikonix360]

I have a MSI GT 710 2GD3 LP graphics card in my main pc and I currently have the Core clock at +400 and memory clock at +240 in MSI Afterburner.

How much higher can I go on both the memory and core clock without stability issues?

Unfortunately adjusting the core voltage is not possible.

I do seem to remember being at near safe stable max for the memory clock however.
