A PLL read isn't needed so there are no side-effects like sata controllers hanging or problems with sleep followed by resume. The PLL data to be written is fully configurable to your specific requirements.
File Info: ClockGen 1.0.5.3 Once you get your PLL model selected, click on 'Read Clocks', then open the 'PLL Control' window. Notice that the number of sliders depends on the PLL model features. Some models also only support a predefined set of frequencies, and therefore may show a 'step-by-step' slider. Once your new clocks are choosen, clock on 'Apply Selection' to make them effective. If you want to come back to current values, click on 'Reset Selection'.
The 'Clocks' window shows the current clocks in real time. It is independant from the selection window, so it will tell you if the new clocks were really applied. Notice that the CPU clock may vary if the CPU uses a clock modulation mechanism, like C1E or Speedstep. Load your system if you want the CPU to run at full speed.

I've got an Intel D845PESV mobo and a Pentium IV Northwood 2,8Ghz processor (533FSB version). There are no overclocking options in this mobo's BIOS. Wherever I looked, people said it's impossible to overclock with this mobo.
However, I found this ClockGen application which supported PLL's used in some Intel boards (not mine, though). I decided to give it a try with the Cypress CY28346 used in the Intel D845GBV and D845EPT2 mobos.
The program was able to read the clocks and modify them. On first attempt I tried 3Ghz. No problems here, system stable etc. I loaded up CS:S and BF2142. Additional frames, yay! Then I tried 3,2Ghz. Worked for a while then I got a BSoD and the system restarted a few times until it changed back to 2,8Ghz.
Back to 3Ghz - I set it and click apply, this time the system reboots without a warning, but the CPU is working at 3Ghz so all's good. Next attempt - about 3,1Ghz - I click apply and there's a.ing loud beep in my headphones (not the PC speaker). Uh oh, I reach for the reset button.
So far 3Ghz seems the maximum stable setting. However, today the application was giving me problems, it seems. My brother was using the PC in the morning without a problem. He turned it off after he finished and I turned it on about 30minutes later. After choosing the profile and a few seconds the PC crashed (or actually acted as if it was under really heavy load, the cursor moved every 20 seconds when I was moving the mouse). I did a reboot, got a 'choose proper boot device' sort of message, and the cure to this was to plug out and back in the power cable to the HDD (making me think it was a HDD problem but turns out it wasn't). After a few resets I chose another Windows profile, got a 'failed to initialize driver' from Clockgen, renamed the folder it was in (so it wouldn't start upon logging to my profileand crash my PC) and relogged to my profile.
I manually started clockgen, set 3Ghz as usual, and everything's OK now. So, kinda wtf really. Back to the actual overclocking - isn't 3Ghz a bit weak on a 2.8Ghz Pentium? I know that software OC is not as effective and safe as hardware OC (BIOS), but still - is there anything I could do to bring the clock a bit higher? The CPU temperature is fine BTW, no overheating.
