Overclocking

Overclocked proved to be fairly fruitless on the TA75A+. With PCIe tied into the CPU bus, going any higher than 109 MHz resulted in many issues that would lead to BSOD's, and the BIOS does not feature an internal divider that kicks in at 133 MHz on the CPU bus, like some other AMD A75 products, leading to very low overclocks. However, given the price of the board compared to those other products, we find this to be of very little issue, but it is a bit disappointing considering the last Biostar board we looked at, the TZ68A+, offered overclocks that mimicked what we saw on some of the much more expensive products. Hopefully future BIOS updates will allow for a bit more, but even if they don't, we still won't let this weigh in too heavily on the final score.

Overclocked Performance Summary

Only small gains are to be had while overclocking, speed-wise, so only modest gains are noticed in wPrime.


SuperPi shows the same as wPrime when overclocked...just a small boost.


Cinebench seems weighted like the synthetics, with the Biostar TA75A+ showing some gains, but not much overall.


CodeMasters' F1 2010, on the other hand, does show some significant gains, most likely due to the increase in CPU speed, but because stock numbers were more than adequate for good performance in this application, the results aren't such that we question the usefulness of overclocking with the Biostar TA75A+.
