It's probably throttling back due to exessive heat

It could be the heat as CTurbo suggested.

I believe it could also be due to the way Intel deals with multipliers when all cores are stressed.

If a single core is stressed it should hit 4300MHz. However when multiple ones are stressed it drops down to 4100MHz.
