Testing for the AMD Phenom 9600 Black Box Edition was conducted as per the previous page.
In order to achieve the overclocked speeds of 2.7GHz, AMD Overdrive was used, the VCore voltage was raised from 1.25 to 1.37, the system RAM was run unlinked, and the NB voltage was not changed. For the stock heatsink, the overclock of 2.7GHz was achieved at the same voltages all around. The stock heatsink was used just for comparison and, as you can see, its temperatures are significantly higher.
As I stated earlier in this review, it's very hard to find a CPU cooler that will adjust properly to the constant changing ambient temperatures in Florida. The Ultima 90 is no different than any other when the climate control in the house shuts off; within 5 minutes the temperatures increase two to three degrees Celsius. All temperatures reflected are taken when the climate control is off.
