[SOLVED] i7-2600k 5Ghz dead after overclocking

[undergroundcharon]

I have 2600k, acted a few months on 5 ghz on 1.500v. Yesterday BSOD 0x000000124 appeared, I raised stretching on 1.505v and this morning the processor died. Six short of signals from pc speaker. Another cpu i3, and the computer works.

[strike]Lesson learned, you can't run that kind of voltage on a CPU that doesn't particularly like to run over about 4.3Ghz without there being damage. 1.5v is past the safe point. Anything beyond 1.45v is almost certainly going to destroy your CPU or something on the voltage regulation section of the motherboard.

Disregard this nonsense. My eyes saw 2600x, rather than 2600k. LOL.

Exept that, I was correct that the voltage is way beyond the death voltage, even for the 2600k.

With the 2600K installed, first try clearing the CMOS. If the problem is related to the overclock alone, that will clear the overclock.

On an AMI BIOS, six short beeps indicates a "Gate A20 failure". The recommended fix is to "The keyboard controller IC has failed, which is not allowing Gate A20 to switch the processor to protected mode. Replace the keyboard controller."
Try a different keyboard. Try a USB keyboard.

Voltage segment here might be more useful. http://www.tomshardware.co.uk/forum/id-1800828/intel-temperature-guide.html

Wrong 2600 darkbreeze

Also five short beeps is processor error (in the event that you miscounted).

Another processor i3-2120 works fine. I was trying again to install 2600k, but does't work. Clear CMOS didn't help.

Oops, you're right. My bad, LOL. Appologies.

1.5 volts ??? Wow !!!

Apparently you have been seriously misinformed! It is not OK to run 1.5 volts on a processor with 32 nanometer microarchitecture! The last Intel processors that could run voltage that high was the 65 nanometer Core 2 such as the Q6600. When it comes to Core voltage, one size does not fit all:

Here's the maximum recommended Core voltages per microarchitecture from 14 to 65 nanometers since 2006:

Excessive Vcore and Core temperature may result in accelerated "Electromigration" - https://www.google.com/?gws_rd=ssl#q=Electromigration

This prematurely erodes the traces and junctions within the processor's layers and nano-circuits, which will eventually result in blue-screen crashes that become increasingly frequent over time. As a rule, CPU's are more susceptible to Electromigration with each Die-shrink. However, the most notable exception is Intel's 14 nanometer microarchitecture, where advances in FinFET technology has improved voltage tolerance.

The 2600K is still a nice processor. A little research could've saved you from killing it. As per 13thmonkey's suggestion, see Section 8 - Overclocking And Voltage:

I will buy another 2600k

 

[johnbl]

might look for chared pins/pads on the cpu.

I will buy another 2600k
