Overclocking via NVIDIA's GPU Boost was covered in our ZOTAC GTX680 review so I won't go into detail here on the attributes and pitfalls of using this method to overclock a GPU. Suffice to say it is relatively easy to use if somewhat a little awkward when determining the weak link in an overclock.
The MSI GTX680 OC Twin Frozr, as the name suggests arrives pre-overclocked to an already impressive 1058MHz on the core which translates to a boost clock of 1124MHz. The memory speed remains untouched at 1502MHz (6008MHz effective).
Using MSI's own Afterburner tool we ramped up the voltage and power boost to the maximum settings and set about overclocking the card.
After only an hours work, we managed to overclock the core to 1214MHz resulting in a boost speed of 1279MHz. During testing we actually saw this boost hit 1300MHz briefly too which is verging on the ridiculous! For suicide benching we did manage to clock the card a little higher to 1250MHz but sadly this resulted in Heaven locking up occasionally so we settled for the rock solid stable 1214MHz. Their was also room to manoeuvre with the memory too which resulted in a maximum stable overclock of 1570MHz(6280MHz effective) which is a great result for MSI.
