OCC has published a new article on the AMD TWKR Edition CPU
I am very impressed by what I achieved with the TWKR. Going extreme
cooling allowed for a great boost in frequency. What amazed me the most is that the processor required much lower voltages than the previous Phenom II chips. Even when overclocked to around 5GHz, it did not need more than 1.6V. However, I know there is much more left on the table. I felt dry ice could not provide the temperatures needed to scale to the top of the processor's performance. In fact, the processor ran better with lower voltages than 1.6V. My theory is that maybe it was getting a bit too warm when I pushed high voltages in it, which it is supposed to sustain without any problems due to its high leakage. The same thing happened if I increased the integrated memory controller voltage beyond a certain point at the same time as the core voltage, even if it ran fine when the only overclock was on the IMC. In other words, I felt dry ice cooling was still very limiting for the TWKR Edition since it did not allow the high voltages it can take.
