overclocked my HP Pavilion a6814y w/ IPIBL-LB Benicia mobo and Intel Pentium E5200 running at 2.5 ghz factory to 3.2 ghz. 252 Mhz FSB and 400 Mhz DDR2 Ram to 504 Mhz (Memset timers, 6-8-8-8-24) DRAM, seems stable. Of course the BIOS are locked with no options for OC whatsoever. Used ClockGen PLL IDT CV174C (ignore PCI-e) set to 252 Mhz FSB at startup. CPU-Z, Core Temp or CPU Thermometer(don't use speed fan, inaccurate). Use Crystal CPUID to set the multiplier and volts on the fly. Pretty safe to try if you have the same mobo and CPU, try at your own risk though and your settings may vary if you have better voltage, more latent timings in your Ram and a better CPU although mine is great for OC'ing too. Make sure your temps don't exceed 65*C Core Temp if you have the same processor(max Core Temp is over 70*C). If not Bing or Google or whatever to see what yours is. I opened up my tower and put a little personal fan beside it, not necessary but it idles at a cool 38*C and I haven't seen it go over 50*C yet. One trick is if you don't want to use an extra fan is to set your Voltage down with Crystal CPU-ID, but not more than 2 or 3 settings below factory. Experiment if it fucks up and BSODs or freezes just Hard Reboot and your system will boot to the last saved good config. Use at your own risk, it is rather safe though.
