| Underclocking? Does anyone here have any experience underclocking to lower voltage and heat? Have you made it stable?

| I have done it before by accident. It actually ran for a few days fine. I only noticed it during gaming. I think I had mmy mobile 2400 down to 1 ghz... What are you underclocking? How much? Are you having trouble?

| Well I have a HTPC running a 3200 and it really gets hot. It is in a closet with poor airflow so I was thinking that if I underclocked and lowered the voltages It may run cooler. I just use it to watch DVDs and run my HTPC software (SAGE TV). No games or anything like that. But it has to be stable because I leave it on 24-7. It is the machine in my sig.

| I've generally not come across any issues with underclocking. My personal recommendation would be to take the clock speed down first, before adjusting the voltage at all. Once you have your desired clock speed, then you can see if you can lower the voltage at all. Run the same sorts of tests as if you were overclocking to ensure things are stable. Generally CMOS circuits have a power consumption that's nearly proportional to speed, so halving the speed pretty much halves the power consumption.

| Underclocking? Is that a "bad word"?

I remember reading about someone who ruined their Sempron by underclocking. But they took it quite far.

| I know of a lot of people just lowering the voltage befre doing anythig with speed. don't think it's a good idea if you need it really stable. turing cool and quit on is the best idea.

| What board do you have? Setting the FSB to the next lower is a good start. then reducing the voltage until you are no longer stable then bring it back up.
