I7 2700k downclocks to stock speed under full load. Please help!

Hello

I'm having a problem with my i7 2700k

If I try to overclock past 4.6 and run a stress test( intel burn test or prime95)

My cpu will drop from the overclock to stock speed of 3.5ghz for a couple seconds and shoot back up.

It don't do it at 4.6ghz. I have a custom water loop so my temps are in the low 60s at the hottest core when under full load.

The rest of the cores are in the 50s. I have speed-step and all power savings disabled and power management set to active

in windows. I have tried everything. I have been overclocking for over 10 years. This has me just stumped. The vcore and muliplier drop to stock

in hwinfo.

I am beginning to think the chip is bad.

Any help or suggestions on this would be greatly appreciated.

Thank you

Kevin

Hello Kevin,

The processors clock speed of Intel® products will increase the speed automatically based on internal components and configuration inside the processor. I am afraid that this cannot be changed or handled manually. It is also important to say that Intel® does not support Over clocking.

My best recommendation is to set the defaults for the processor and run the Intel® Processor Diagnostic Tool to diagnose the unit and it will generate a report in case of failure.

You can get this software at the following link:

I figured it out. As i said i have the custom water loop/ Do to there being no heat sink and fan blowing on the vrms they became to warm during stress testing and was throttling the clock speed.(even though they are cool to touch) I added some fans to the vrms and problem solved. At what temperature with the 2700k begin to throttle and what is the max safe temp for 24/7 use?

Thank you

Hi Kevin,

The processor has a lifespan of 5-6 years under heavy and full work load. The processor temperature can be between 40C to 78C. The temperature can go up to 92C or 100C but at that point it is considered overheating.
