125W = 95 W

post #1 of 19
Thread Starter 
Ok so right now i'm using an ASUS M5A78L-M LE coupled with a Phenom II X4 B45 @ stock speeds (X3 445 UNLOCKED WITH L3 cache). Since the processor is rated at 125W, i'm kinda bummed about it. I got no real worries about the VRM's blowing courtesy of ASUS' trademark VRM protection feature. It's just that CPU throttling kicks in WAY too often while i'm video encoding+playing BF3+streaming. So is there a way i could undervolt the processor so as to reduce the TDP by a tad atleast? Right now the things sitting at stock speeds @ 1.28v. Planning on reducing the volts down to 1.20 or 1.24 at the very least. Problem is however i can't really find an option to do that in the BIOS. All i'm getting to do is overvolt the CPU but not undervolt. Besides reducing the multi, any other suggestions guys?

you should go to CPU/NB VID/FID menu. it is a submenu where you can adjust the CPU voltage and multiplier. same goes for the NB.

I tried doing that. Right now everything's set to auto. I can't go any lower than that. All i get to do is increase the voltage mad.gif

Awesome, I undervolted my processor down to 1.15v, completely stable!! Temps went down by 6C thumb.gif. The current TDP is @ 110w down from 125w! Rep+


Here's a screen:

See, this is why you should buy a motherboard that's actually capable of handling the power draw of 4 cores or more.  Because if you don't, (depending on the mobo/manufacturer) you could enter end up with burnt ash or performance loss during load tongue.gif

Noted xd thumb.gif. Being just a college-going kid, i never exactly had a top-of-the-line budget at the time. The MSI 785GM-E51 was actually falling within my budget but there was no way i was going in for an MSI (thanks to you biggrin.gif). I'd rather take my chances with a 3+1 phase ASUS. Anyway I've been saving up for a Crosshair V Formula and it ain't too far away. For now lemme enjoy my low ass voltages. Just happy that the TDP's gone down to almost 110W.

Actually you're only pulling 91w. thumb.gif

Roughly... so actually you're pulling less than you were before. thumb.gif

How am i pulling just 91w confused.gif. Before on stock voltage (1.30v), the processor was drawing 125w. With the voltage reduced to 1.15, it should be drawing about 110w according to my calculations.
