i7 3930K Constantly Throttling?

post #1 of 10
Thread Starter 
When my CPU hits 75c, it throttles. My VRM heatsink is too hot to touch and my BIOS settings are set to disable turbo and any features designed to throttle the CPU speed and voltage.
I am only running at 4.2Ghz @ 1.34v.
I tried pointing an NF-F12 to the VRM heatsink and it hardly makes a single difference at all.

Is this a built in thing that you can't disable, or is the mobo throttling due to high VRM temps?
Thanks for the help.

did you increase cpu power percentage? to 140% maybe it that and be sure to have the most recent bios installed

Yes, I increased almost every limiting setting.

that's why NH D14 does better job with cooling VRMs than CLCs
post #5 of 10
I have a NH-D14 for sale *cough* *cough* $60 shipped *cough* *cough* hahahaha

That is strange.The TJ Maxx of the 3930k s 91c, right? I know some chips throttle at a little less than the TJ Maxx, but still. 16c is pretty far off. I'll have to ponder on this one.

The GA-X79-UD3 motherboard had known issues with VRM throttling after Gigabyte updated the bios to fix the "caching on fire" issue. There might be a beta bios to keep the setup from throttling.

"catching on fire" issue??? Jesus they need a whole recall if that was an issue!

The defective BIOS design was found when some enthusiastic players were testing the limit of overclocking of Gigabyte's high-end X79-UD3 motherboards, which then caught fire and released smoke when the devices were overclocking, revealed industry sources.


Maximum PC: Gigabyte Rolls Out Crucial BIOS Update For Overclockers With X79 Mobos, by Brad Chacos, 12/27/2011

Gigabyte’s Chinese branch announced the faulty CPU VRM is a widespread issue and recalled the GA-X79-UD3, GA-X79-UD5, GA-X79-UD7 and G1.Assassin 2 mobos. US users, meanwhile, get a critical BIOS update.

There are some conflicting reports about the BIOS update out there. TechPowerUp reports that the patch will throttle the CPU when it’s stressed to protect the VRM and keep your board from frying, but claims that the throttling also apparently puts the brakes on any adventurous overclocking attempts. A Gigabyte rep told us that this is not true, however.

Oh my god the anticipation in that video was worse than the scariest horror movie I have ever seen. That is just horrible.

And that is one reason I didn't get a gigabyte board this time around... my old ep45-ud3p board went up in flames too frown.gif
