This seems to be one of my best yet-- I just wanted to know what anyone else thought of it.
This is done on Stock Voltage, with only some minor modifications to the heat sink (Still completely Passive).
CPU:
Intel Pentium PP75 (Non-MMX) Y056.
Overclocks:
75Mhz > 100Mhz (Overclock PLL from 50Mhz > 66Mhz) @ x1.5 Multiplier. [Stable]
100Mhz > 133Mhz (Overclock PLL @ 66Mhz) @ x2.0 Multiplier. [Stable]
133Mhz > 166Mhz (Overclock PLL @ 66Mhz) @ x2.5 Multiplier. [Stable]
166Mhz > 200Mhz (Overclock PLL @ 66Mhz) @ x3.0 Multiplier. [Unstable, no Boot to BIOS, Speaker Static].
I only benchmarked at stock, and current speeds.
SYSBench 4.78 (Stock 75Mhz CPU, 50Mhz PLL):
CPU: 54.87
RAM Bandwidth: 130.10MB/s
SYSBench 4.78 (Overclocked 166Mhz CPU, 66Mhz PLL):
CPU: 120.41
RAM Bandwidth: 173.22MB/s
So, a 222.22% Overclock yielded a 219.44% performance increase (Pretty much Linear Mhz/Perf increase) from stock. Again, no voltage modification.
That's pretty good right? Anyone had a similar experience to this?
