Thermal Throttling at 61 C on 3750k?

[ajrettke]

I just got a new ASrock Z77 Pro4 and an 3750k. I'm just starting to push it, I'm water cooling the chip as well.

I started out at 4.5 with an offset of .060, disabled all C states and speedstep. But regardless I keep throttling down to 3.4ghz and the temps immediately drop 10 degrees for a while then jump back up to the screen shot below for 20-30 seconds and throttles back.

What am I missing? Do I need to disabled thermal throttling? Are my temps not reporting right and chip is protecting itself? Just seems odd to be throttling so quickly.

You disabled C-states and all that, and are using OFFSET?

What are your Turbo Power Limits set to in the bios? Thermal throttling is when the CPU multiplier drops down to 16. Turbo boost throttling is when the CPU drops down to the default multiplier which is 34 for a Core i5-3570K. Increase your turbo power limits and you will be able to run fully loaded at the full Turbo Boost multiplier. Check out RealTemp, go into the Options window and turn on a system tray icon and then right click on that icon and there will be a menu option in there that will let you look at what your power limits are without having to reboot.

There is no need to disable SpeedStep - EIST for Ivy Bridge CPUs. If you want your CPU to always run at the maximum turbo multiplier then disable C1E, C3 and C6, set your Control Panel - Power Options - Minimum processor state to 100% and adjust your turbo power options appropriately.

it could also be your VR taking down the frequency.

Thanks for the reply,

Right now turbo boost is .047v, offset I've increased to .190v, my vCore is ~1.35v when at 4.7ghz, when it goes back to 3.4ghz vCore moves down to ~1.19v.

Do I need to shift my turbo boost offset to ~.2v and regular offset to .05v? Or just increase turbo boost voltage more since my temps are good?

It will run prime/intelburn fine for a minute or two then it will start the throttling.

do you have the option to increase the current/watts threshold?
