|Operating System||Vista Ultra 32-bit|
Idle voltages were measured by powering the system at the default speeds, and voltages with no applications running in Windows for at least 30 minutes.
Load condition was established by running loops of the SM graphics test from 3DMark06 at 1600x1200 resolution with enabled 8x AA and 16x AF and Orthos (4 cores) at the same time for 24 hours. In addition to this, I initiated a data transfer between hard drives using SyncBack. All voltage rails were measured using a digital multimeter by tapping into various connectors. In addition to these stressful applications running, the loaded system was overclocked and overvolted to add more demand to the CPU and graphics card.
The chart above details the results from digital multimeter recorded on +12V, +5V and +3.3V rails. Only slight fluctuation of 0.02V was noted on +5V rail. Remaining +12V and +3.3V rails were rock stable, with no fluctuations recorded! This is the best voltage regulation I have seen so far.
