Hi,
I have an IBM branded Cyrix 6x86MX PR200 (75Mhz x 2) running at 2.9V on a Zida 5SVA socket 7 mainboard.
I know that these Cyrix branded processors are not a very popular to overclock but I decided to give it a try and noticed I could run it "stable" at
- 66 x 2.5 = 165Mhz without changing the voltage.
- 75 x 2.5 = 187.5Mhz at 3.2v (anything lower resulted in win98 failing to start)
"stable" = ability to boot into windows, run some benchmarks, cpu not getting super-hot.
I did not experience any crashes but the CPU did get hotter with the 75 x 2.5 setup so I didn't leave it running too long.
I do have some questions :
- What would be a safe / responsible way to continue ? Neither CPU-Z nor hardware monitor show me any sensor data (voltages / temperatures). Can I put a temperature probe between the CPU and heatsink/cooler (or is there another way to read out the temperatures) ?
- With the 66 x 2.5 systems most benchmark results were also faster than the 75 x 2 setup. On what specific area does this setup cripple the performance (lower FSB than stock but overall higher clock speed).
- If I understand correctly, upping the voltage from 2.9 to 3.2 will produce more heat, but the cpu should be capable of working for a prolonged time at 3.2v with a proper heatsink / fan ?
