" rel="nofollow - Question regarding VCCIO and VCCSA. Just set up my new system with Taichi XE and 7940x and did some overclocking.

Running it 4.4GHz all vcore 1.125v and VCCIN 1.8v. AVX Offset 6 (3.8GHz). Mesh 3GHz 1v. My tridentz using it's xmp profile.

I noticed that the VCCIO Auto was 1.3v and VCCSA Auto 1.35v. Isn't this a bit high? What is the default for the CPU?

I set it manually to VCCIO 1.05 and VCCSA 1.0v (I have not tested any lower).

Also is LLC2 ok for this modest overclock?

Thanks in advance.
