Biostar provides the TP45 HP broad enough voltage and frequency controls to get the best performance out of most parts, and our overclock tests will show how stable these settings are.
The TP45 HP’s overclocking menu contains CPU clock speed and multiplier, boot strap, and DRAM ratio settings, with several sub-menus providing advanced options.
The DRAM timings sub-menu provides all the important controls, but using automatic (SPD) values is an “All or Nothing” situation as individual settings don’t have the automatic option. The TP45 HP couldn’t keep our Crucial Ballistix memory stable at DDR2-1066 CAS 5-5-5-15 (2.2 Volts), so we were forced to test it at a similar-performing DDR2-800 CAS 4-4-4-12.
The Clock Gen sub-menu provides PCI Express frequency, skew control, and CPU clock drive strength control.
The TP45 HP’s Voltage submenu has all the needed settings for a stable overclock, except that the southbridge 1.1V line is tied to northbridge voltage.
Like most other performance motherboard makers, Biostar can store custom BIOS settings in one of several profiles, handy for quickly returning to a previous set of timings, clocks and/or voltages.
