...but what about 25%? 33%, 70%?!?
Many machines are really at the limits when you try to OC. But some will give you astonishing results without loss of reliability.
My world is not Windows, i'm a Unix geek. If i OC too hard, my OS will notice and "panic" or SEGV or whatever. I do not tolerate three crashes per week. When i OC, then i go near the limit but not over it.
I have tried to OC a lot of machines in my life and most of them actually weren't worth the effort and i went back to standard settings. And no CPU was killed by my moderate tries.
But some times i hit a CPU that goes amazingly far beyond specs. Sometimes i can only guess why. Here are my top OC'd CPUs:
Sun 3/60 (68020@20) runs fine @24 and @25 MHz
HP Vectra 4/50 (486DX2@50) runs fine @66 MHz
Pentium-II 266 runs fine @448 MHz
Both the Sun 3/60 and the HP Vectra are no single exemplars! I have OC'd sucessfully several of each type!
On the Sun 3/60 i usually spend a passive cooler for the 68020 and the 68881 FPU and replace the 9 chip SIMMs by faster 3 chip types.
The Vectras attracted me because their CPU was totally cold. Raising the FSB to 33MHz gave them a nice boost and the CPUs became only moderately warm.
The P-II-266 should be a Klamath, but has obviously a Coppermine core because it sucks only 2.0V. I wasn't very surprised when it ran perfectly at 4*100 MHz. With an Abit BH-6 mainboard i was finally able to run it at 4*112 MHz (and 2.1V core voltage).
