However, this utility offers a much broader spectrum of options than just parameters monitoring. It also allows performing complex system overclocking, for instance. Besides the default system settings, the OC Guru option enables three profiles: Turbo, Normal and Quiet. Each profile has preset overclocking parameters (216, 210 and 204MHz respectively) and appropriate rotation speeds for the system fans. Besides the three preset profiles you can also create up to three custom profiles of your own:
There are quite a few programs that allow overclocking from the Windows, but the beauty of μGuru tool is its complex approach to overclocking. Namely, you can not just raise the CPU frequency but also make sure that its Vcore goes up simultaneously as well as the Vmem and rotation speeds of certain system fans. AutoDrive option allows to enabled the preliminarily configured profile that will launch upon activation of certain applications and tasks, which is also very convenient.
And you do not need to launch the full screen interface for this utility every time you need to do something. There is a smaller interface panel available (you can also adjust the level of transparency for your windows).
Or you can even shrink the window into a narrow panel like this:
Unfortunately, this great utility has a few noticeable drawbacks: no software tools are impeccable these days. During our test session the system would very often display the BSOD or reboot. And this would mostly happen during the simplest actions such as “Apply the last loaded profile”.
So, this utility cannot replace Cool’n’Quiet technology and in fact it really needs to, because the Cool’n’Quiet technology can only work on ABIT AN8 32X with the default CPU settings. On all other mainboards clock generator frequencies and processor Vcore other than the nominal do not stall Cool’n’Quiet technology and it only stops working only when you change the multiplier. In case of ABIT AN8 32X, even if you simply set the parameters configuration from Automatic to Manual (without really changing the settings themselves), the Cool’n’Quiet technology will stop working right away. You cannot even change the Default profile settings in the μGuru utility, because this profile is connected with the BIOS settings and Cool’n’Quiet will stop working right on the next system boot-up.
The preliminary CPU overclocking tests were performed with the reduced memory frequency in order to eliminate the possible limitations imposed by the memory. However, we found out later that ABIT AN8 32X mainboard cannot retain stability at higher frequencies with the Command Rate timing – that has huge influence on the performance - set to 1T. I didn’t really worry about the fact that our memory couldn’t work at 280MHz during “synchronous” CPU overclocking up to 280MHz: it was still very close to what the Corsair CMX512-4400C25 memory modules could do. However, even at 270MHz our memory could pass the tests with the 1T/2T timing set to 1T.
