Help me push this 2500k that little bit more!

[tintin82]

So I have had my 2500k at a solid stable 4.6 ghz for years, however over the past few days I have tried to push that little bit further with either the RAM to 2133, or the core to 4.8, however nothing more is achievable above what I have, even though my temps are around 70C with IBT.

I have attached some images incase I have some obvious setting wrong or I have missed something completely. No matter how much I put up the core voltage it will not pass IBT.

Tempted to get a 6700K and 4.8ghz although think there is life left in the 2500k yet,

Any ideas?
Thanks

Put Ram to stock first & see what your highest CPU clock is.

I've never got mine to run at 2133 with any meaningful overclock on the CPU anyway.
