ECS Z77H2-AX Motherboard
Overclocking Options
Contents
The ECS Z77H2-AX has a few overclocking options. Below, we list the most important ones (March 03, 2012 BIOS):
- Base clock: From 99 MHz to 150 MHz in 1 MHz increments
- CPU core voltage: From +0.010 V to +0.630 V in 0.010 V increments
- Integrated graphics processor (AXG) voltage: From +0.010 V to +0.630 V in 0.010 V increments
- Memory controller (“IMC,” “System Agent,” VCCSA) voltage: From +0.015 V to +0.945 V in 0.015 V increments
- CPU VTT (“I/O”) voltage (wrongly labeled as “System Agent”): From +0.010 V to +0.630 V in 0.010 V increments
- CPU PLL voltage: From +0.010 V to +0.630 V in 0.010 V increments
- Memory voltage: From +0.010 V to +0.630 V in 0.010 V increments
- Chipset (PCH) voltage: From +0.010 V to +0.630 V in 0.010 V increments

The motherboard also has voltage monitoring points, where you can monitor the CPU (Vcore and memory controller), graphics controller (“VAXG”) and memory (“DIMM”) voltages.
