I've updated my 600e to PIII 650, run fullspeed , but it is too hot ,when play rmvb film ,the cpu temperatue is up to 90℃. So I made CPU core voltage down to 1.55v,the cpu is cooler ,but the full speed mode is not stable,sometimes can not run fullspeed,just 500MHz.And the cpu temperature is higher more.

I tried other core voltage,and I found 1.35v is the most fitable voltage for 600e.

Yea 1.35V core works on the earlier MMC-2's but is not stable for the 750Mhz, 800Mhz, or the 850Mhz MMC-2 boards...the lowest stable vcore that work with thoughs is 1.48. That is done by removing R3 and R14 on the MMC-2 module.

To get the 1.35V vcore that he is talking about you need to remove R5 on the MMC-2 board which gives a .2V vcore drop. This has been proven to be realativly stable on the 500Mhz to the 700Mhz MMC-2 modules.

A little articsilver 5 between the CPU and fan would help that.
