 Post subject: AMD XP-M 2400 35W or 45W for undervolting?

Im building a HTPC system and naturally want it as quiet as possible. An AMD XP-M 2400 on a DFI Lanparty Ultra B seems the way to go for undervolting and underclocking. Motherbard already purchased and now I'm going to order the CPU. Am I right in assuming that the 35W version will perform better when it comes to undervolting? I want to make my system as cool and quiet as possible.

Thank you for any and all help!

The 35W can simply run within AMD's tolerances at lower voltages than the 45W models.

Desktop = 1.55V
XP-M 45W = 1.45V
XP-M 35W = 1.35V

I just got an XP-M 2400+ 35W and an EPoX 8RDA3I+ Pro, and it's running great sofar. I currently have it set to 200x10 @ 1.40V. You can get down to 1.1V, but anything lower than 1.4 can only be done through software.

I can get the 35W version on Abit NF7-S v.2.0 at 1.2V and 1200mhz, but anything lower becomes "iffy", meaning sometimes it posts sometimes it doesn't, so I left it at this and I'm able to cool it passively at 56.5C with prime on for about an hour, using the SI-97 heatsink.

Ok, a 35W it is :D

Im also planning to use a SI-97, but not passively. Instead I'll put a nexus or panaflo 92 mm, running at 5V, on it. It will live in a desktop/htpc case so I'll mount the fan to suck air from the HS and duct it to a vent in the top of the case. In this environment it seems better to get the air out of the case as soon as possible. I hope that this, along with the PSU fan will move enough air. Air intake will be "passive" through a lot of holes along the side of the case.

Thanks for all the help
