Overclocking

Overclocking CPUs on the TZ68A+ proved to be a real treat. We weren't expecting too much, given that the Biostar TZ68A+ is a entry-level mainstream-class product, but the Biostar VRM held up really well, considering it only employs a 4+1 design. We managed our usual 4.5 GHz overclock with the usual voltage, 1.264v, with loadline calibration enabled. The TZ68A+ allowed our Corsair Dominator GT memory to reach 2133 MHz without any problems, except for the usual boost to VCCIO, raising the voltage there up to 1.125v.

We did have issues using the auto-overclocking software, but even so, manual configuration via the BIOS proved to match the results offered by the other P67-based boards, with our 4.5 GHz clocks requiring similar voltage, and power consumption, as some of the more expensive boards we have tested. For an entry-level product, these are fantastic results.

Overclocked Performance Summary

Cinebench provided a substantial performance increase when over clocked, something that resounds true through the entire series of SandyBridge products.


Likewise, SuperPi 32m results proved the same as Cinebench, with substantial performance increases that are noticed on previous Intel platforms.


WPrime 1024M numbers further the results, showing that there is true power available when overclocking the Biostar TZ68A+.


For a bit of 3D action, we fired up CodeMaster's F1 2010, to be unimpressed with the performance boost offered, compared to the other products, but at the same time, proves to highlight that the CPU is near optimal performance for this application, even at stock speeds.
