Phenom application for undervolting

Did anyone find any Windows application that allows me to mange the multiplier/voltage in similar way like RMClock. I know that RMClock is currently beta testing new release that might finally support Phenoms, but are there any other apps that have been updated to support the Phenom? I'm stuck on AM...

AMD 740G chipset

New unannounced chipset, AMD 740G http://www.pcper.com/#NewsID-5998 From the look its a 55nm shrink of AMD 690 (80nm). Checked some internet shops in Poland, and area already available. The greatest strength of this platform is likely the power consumption. At idle, with 2GB of memory, a 500 GB HD, ...

Overall Gigabyte is out as it is simply a tad to big, it uses full 244x244 format. I need something smaller.

I'm just thinking. Should i go for the 90nm 35w version (safe bet it will work) or 65nm 65w version and undervolt it. (but then it totaly depends on the motherboard - or Linux Kernel Mod)

Suffice it to say, this board is high on my list. But as luck, one of the local shops started to carry X2 3800+ EE SFF 35W version :) So that brings lots of options without even undervolting. I'll will double check if any of them carry the X2 3600+ (65nm version) as most seem to have the 90nm EE ver...

It is possible that the efficiency of the power supply has changed. Since removing components does not add but remove load. Remove the hauppage pvr 150 and check the power consumption when its removed. This would permit to exclude or include it as part of the increase of the power. As for the new PS...

Intresting results.

But looking at the available data its hard to judge if its a strait line or a curved line.

Is it possible to run more samples?

But i have to say, this approach is quite intresting in checking power consumption of the CPU. Well done.

I know that DFI and most other boards had overvolting with C&Q by having voltage adjustmen like Vcc 104% etc. It be nice if there is a board that permits undervolting with C&Q. But from what you are saying, most people easly reach near 1.0V for 36...

Did the standard kit, PSU without the ac-dc brick, come with additional cables like atx 12v 4 pin plug? Or is that extra?

I live in poland, and just recieved 4 nice picopsus, but only they picopsus without any additonal cables. And board won't boot without the additonal atx 12v 4 pin.

I've seen here on SPCR that there was a single reference to 240VAC test on a powersupply, and there was a difference, would be nice if SPCR could do a single test, taking the most efficent powersupply and see how much better it performs on higher voltage.
