The supported intervals and increments are similar for the Chipset Voltage and FSB Voltage parameters, however, they are not the same. The increment equals 0.025 V up to +0.35 V value and then increases to 0.05 V. FSB Voltage changes with fixed increment up to maximum value of +0.75 V. And the increment for Chipset Voltage increases to 0.1 V starting from +0.4 V and remains like that up to the maximum of +0.7 V.

CPU Core1 GTL Ref Voltage, CPU Core2 GTL Ref Voltage and MCH GTL Ref Voltage support similar value ranges and increments.

CPU PLL Voltage may be set to one of the following four values: 1.5, 1.6, 1.7, or 1.8 V. Biostar TP45 HP mainboard uses four-phase Intersil ISL6322 voltage regulator, which operational frequency can also be adjusted.

Exit is the very last BIOS section. It contains standard options such as saving changes, discarding changes and loading optimal settings. Security subsection allows setting passwords and disallowing BIOS updating. We, however, are going to dwell on CMOS Backup Function sub-section.

You can save and quickly load the full BIOS settings profile. Seems like there is only one…

In fact, you can save up to 10 profiles and give each of them a description of up to 50 characters. The time and date will be automatically recorded for each profile.

Even everything we have already mentioned is not all the Biostar TP45 HP BIOS can do. Like ASUS and Gigabyte mainboards, Biostar solutions also have a convenient built-in updating utility that recognizes not only FDD, but also such storage solutions as USB Flash Drive. The only requirement is that should be formatted for FAT16 or FAT32 file system. If you wish to launch BIO-Flasher Utility, press F12 on boot-up.

Now it seems to be all we wanted to mention about Biostar TP45 HP BIOS features. We can’t say it is an ideal BIOS, we have pointed out quite a few things during this part of our review. However, I was sincerely amazed at the amount of options and settings that Biostar TP45 HP BIOS has to offer. And in most cases Biostar didn’t invent anything new: we have already seem most of these parameters implemented on other mainboards. Biostar, however, deserves due credit for gathering all the best functions together and implementing them in their mainboard BIOS. And even though some implementations are not the best ones, we have never seen a more brilliant combination of features before. We have seen them separately or in groups, but never all of them at the same time. And Biostar TP45 HP mainboard has everything one may wish for. Therefore, despite a few issues we pointed out, we give Biostar our highest mark for the BIOS functionality and uniqueness.

However, we have already seen situations when excellent mainboard functionality didn’t prove that great during practical experiments. It is high time we checked out how well Biostar TP45 HP mainboard will cope with practical processor overclocking.
