APM will throttle the chip to hit a power dissipation target if I remember right.

95w or 125W for example, I think the target is hardcoded in the CPU

Tsine, you went thru all that trouble to make a sig and left out your cpu.

how dangerous is to disable APM? I don't have a way to check my VRM temps so will my pc it turn off or something if it overheats or will it burn to the ground?

If I dont OC at all can I leave these auto? usually enable

The Over Drive fix worked for me. Thanks!

Could you please help me? Cpu temp max 57. As you see it's stable. But every 15 sec it's throttling for 3 sec.

Could be a number of things. You could try using the beta version of hwinfo it gives more info. It is possible it is your VRM overheating? If your motherboard doesnt have a sensor you could check temps with a thermal radar or something. Could also just put a fan on your VRM heatsinks if it solves the problem then that was probably your issue. Pretty sure hwinfo can tell you exactly what is throttling if it is cpu related.

Thank you indeed. I'll check it out when i get home thumb.gif

That's an awsome thread!

Really helped me on a 8150.
I just added voltage to low, 1.1, so I am rock stable at 3.6, which was not sure before.
Thank you.

Hello all, I know this is an old thread but here is my experience.
I've had the "now famous" Gigabyte 990fxa UD3 rev 3 board and FX 8120 chip since 2012. For the first 4 years, basically right out the box I ran it at 3.8Gig with -.100 cpuV. All other voltages were auto except memory which I set at 1.5v 16gig GSkill sniper 1600. STABLE. This past winter I picked up another 16 gigs of the same memory. I had to do a little tweaking to get it going.
Then I put a custom loop together originally just cpu block. Got it clocked up to 4.5 gigs with 250mhz fsb clock, stable w/ 1.488 cpuV.
I keep seeing the throttling issue, enabling HPC took care of that for me. I was still trying to push it, could get the fsb clock to 290mhz running somewhere near 4.8gig but not stable. I have an ir thermometer and took a temp of the vrms, it was on deg F so it read like 199 deg. I saw on frozen cpu they have a diy vrms block made by heatkiller so I got one. I had an old danger den amd cpu block that fits the northbridge perfectly (with a custom plate on top for holding it down). Will be retesting this weekend. Hoping to see 300Mhz on fsb which would get NB, HT, and mem clocks where I think they would be optimal, but will also have a profile near where I am now 255Mhz - 4.6Gig for gaming. Will update this weekend.
This mobo has been a little quirky, but pretty stable. No warpage so far. When I put the block on the VRM's, I milled the original heat sink down to work as a back plate w/2mm thermal pad.
