Asus M4A89TD PRO
Anyone remotely surprised by the layout of the M4A89TD PRO should really consider getting an eye test. The location of parameters remain separated into very intuitive sub menu's, which are usable for both new and existing Asus users.
Following on from our BIOS exploration, we commenced our manual overclocking journey. The M4A89TD PRO overclocked effortlessly to a Maximum Base HTT frequency of 315MHz before losing the will to boot. It must be said that this particular sample appeared to be less forgiving with overzealous overclocks however we never had to resort to the dreaded CMOS Clear function. We were a little disappointed by the maximum HTT frequency obtained as this remains 25MHz below the £120 M4A89GTD PRO motherboard and 15MHz below the Asus Crosshair IV Formula (early BIOS). That said, anyone who is spending this much on a motherboard will most certainly choose from AMD's wide selection of Multiplier Unlocked "Black Edition" processors, thus removing any reliance on Base HTT Frequency alone.
On the basis of our previously obtained results, we moved on to try and find a maximum overclock for our trusty Phenom II X4 965 Black Edition processor. We eventually found out limits at 3.90GHz with a Base HTT of 300MHz and a CPU Multiplier of 13.0x. This is typically the ballpark for our processor sample so we were pleased to see that the M4A89TD PRO was capable of maxing it out.
With a maximum overclock obtained, it's now time to kickstart our rigorous testing regime...
