Well James, unfortunately I wasn't able to tweak my venerable desktop PC as much as I had hoped. I forgot to consider the aging motherboard which does not have the option of pushing the BUS past 66mhz, nor the internal clock multiple past 1.5 -- so I was forced to settle for a 33% boost in performance by over-clocking the Pentium-75 (50 x 1.5) to a Pentium-100 (66 x 1.5). I also was going to pump more volts through the CPU but I have no flexibility on that feature either. Looks like I'm in the market for a new motherboard (sure as hell beats an upgrade!!).

I ran a real-world enviroment benchmark diagnostic and confirmed the jump in performance (CPU load at 100%):

P75 -- CPU Dhrystone 49848 = 134 MIPS; FPU Whetstone 33288 = 57 MFLOPS
P100 -- CPU: Dhrystone 64728 = 174 MIPS; FPU Whetstone 33288 = 57 MFLOPS
Net performance gain = 33%

I couldn't get over the user-friendliness of the motherboard. I simply adjusted two jumpers. No noticeable increase in heat; system runs flawlessly.

Again, thanks for the website...I plan on over-clocking every future PC I buy!

Style Pts.
