CM 12.1/13 Kernel that supports GPU overclock

is there a cm 12.1/13 kernel that would let me overclock the GPU and RAM bus as well and not just the CPU ? been skimming through the forum to no avail, currently on teamsek cm 13, it's great but i can't overclock the GPU and bus using it's supplied kernel, i'm even willing to downgrade to cm 12.1 if such a kernel exists for cm 12.1
