Default How high can I overclock my Sapphire HD7950 Vapor-X

I am wondering about optimal o/c my HD 7950 vapor-X. I have it set at core is 1025 and memory 1325. Can I safely go higher than that?

It can handle a higher overclock, but you're entering the danger zone! Use sapphire trixx or msi afterburner. Try and keep temps under 80.

my non vapor X sapphire does 1200 core on stock max voltage and 1300 at least with a little extra juice. Only tried as high as 1375 on my memory.

Plenty of guides out there, I personally max stock voltage limits and see how high it goes by upping one thing at a time in 20MHz increments.

You can push it more I would think. I have a MSI 7950 TF3 in a system here running at 1.2ghz with 1.25V.

Go for it.
