Hello everyone. This is my first time overclocking .I was able to OC my i5 4690k to 4.4 @1.150V on an Asus z87a.

I passed 9.5hrs of prime95 with temps in the low/mid 70s. I plan on pushing to 4.5. However when I run prime95 CPUz registers the voltage I set (1.153v), but ai suite registers it as 1.168 (using ai suite for fan control).Should i be worried about this, or is this an inaccuracy in ai suite.
Voltage is in manual mode. If indeed the voltage is higher than what I set, what should i do.
Thank You
