No, I am also using version 6.2.2.
Are you sure your choosing the right 'Mainboard' and 'Mainboard Type'? It seems that your PLL Type is the reason why the "Fine Tuning" is replaced with the "Not Avail" button. Unless you are using the wrong PLL Type or chose the wrong manufacturer/model, you will not have the option to "Fine Tune." In addition, using the wrong PLL Type and pressing "set frquency" will cause your computer to lock up. My motherboard uses PLL Type 94215, therefore, I have the option to fine tune. If you are choosing the right motherboard/make, the PLL should be selected automatically. If you still don't get the option to "Fine Tune", try using pressing the tiny arrow buttons on the side of "frequency to set" at put it all the way to FSB : 133.3 MHz PCI : 33.3 MHz. Now cross your fingers and press "set frequency" and hope your computer doesn't lock up. If it doesn't then your all good! You can start experimenting and set it higher like FSB : 142.7 MHz PCI : 35.6 MHz. (don't get too crazy and try something like 200mhz). If your computer locks up, then your probably out of luck in terms of using CPUCool.
However, you still misread the program. The readings under the "Frequency To Set" is NOT your current FSB and PCI speed. By looking at your "Current Frequency" of 1236.1mhz, your actual FSB is running at 137.3mhz and your PCI at 46mhz. You said you are able to overclock the FSB using the new BIOS, thats good, and thats what it was meant to do. Both the Official and Unoffical Bios still does not support multiplier changing. Remember that this is mainly an OEM manufacture, which gives you the reason why they didn't include overclocking features in the first place. So for now, you can use use either CPUCool or your new BIOS to change your FSB, which is BETTER than changing the multiplier anyways--it gives you better performance. Now just hope that ECS will releace an OFFICIAL bios that includes both FSB and Multiplier tweaking.
