Ivy Bridge-EP - can I use XCPM for power management?

Have a Dell T3610 with an E5-1620 v2 CPU, is there a way to enable XCPM or am I stuck with AICPUPM? Everything I can find online mentions Ivy Bridge-E is compatible, but nothing about Ivy Bridge-EP, and I haven’t had any luck making it work.

Also wondering about SMBIOS choices - MacPro6,1 would be closest in general for this machine, but I have a RX570 and wondering if iMacPro1,1 would be more beneficial to get best value out of the GPU?
