Hi
I have not found any answer for this here so I presumably have miss it.
Well, I have a Pentium 4-M http://processorfinder.intel.com/Detail ... Spec=SL6FG
And wonder if there is any moderboard on the market that support the speedstep funktion. If it have support for DDR SODIMM it will be extra good.
If there are no moderboard that have that support what moderboard to you recommend then for it?

I dont' know any.
But I doubt it woulb be that useful. P4M undervolt very well. Just lower the VCore in Bios and have fun.
My SL6FH (1.8GHz) currently runs [email protected]
With SETI@home burn, it's 20°C above ambient, passively cooled.
Most of mobos will accept the P4M, at rather different vCore though, so get one the bios can lower vCore (limit is either 0.8 or 1.1v).

How did you achieve that result? Like pxa mentioned, when you put a P4M in a standard s478 MB it runs at 1.2GHz default, so did you have to overclock the heck out of the FSB>?My SL6FH (1.8GHz) currently runs [email protected]
12x multiplier was indeed a problem as chipset couldn't reach "high fsb", and "High speed" DDR modules were unaffordable.
Today there are tons of fsb800 capable mobos and cheap PC3200.
The low multiplier is now a good thing for us, as it's better to get performance by high memory speed than high cpu speed (ram is easier to cool silently).
Set your fsb between 133 and 200 at your choice (depending on your needs, the vCore you set, RAM speed, and your particular chip - YMMV - ). Hope something around 0.8 to 1.2 for vCore for fsb 133 to 200 (figures from memory, sources are vintage web tests and my own ones).
Beware, between ~150 and 199 be sure to set PCI and AGP bus speed to a fixed value.
Oh, if your mobo don't want to lower vcore, there're still some way to have the last word... if solder iron doesn't scare you.
