Rather than see what the limits of what my CPU cooling was and try to break 4GHz on air, I decided to strictly test HTT overclocking. With Phenom II Black Edition processors HTT overclocking is useless when you can easily manipulate multipliers to achieve the clocks you desire. However, the budget CPUs have locked multipliers and stable HTT overclocking is required to push big clocks.
Sadly, going from 50C core temperatures to -70C core temperatures didn’t gain me much with HTT clocking. It more or less made 360MHz stable but anything past that was unstable. Worse yet, AMD Overdrive stopped functioning so I had to boot into Windows at 360MHz. I had a lot of issues getting the board to run dual-channel so this 3D06 run was done with a single 2GB stick of memory and 2 HD 4870×2 at 790/915.
