E6420 - max temperature?

Hi Guys,

I have OC'd my E6420 @ 2.4GHz perfectly fine running at 50C on 100% load but I increased this to be 2.6GHz - this running on load hit 66C

I have read elsewhere that 65C is the max for this processor? How true is this as it was not any official website or anything?
Do this mean that running 65C and above a lot of time will kill my kit? Or is this temperature acceptable?

Cheers,
Jim

Intel maximum is 60.1C.

Basically don't exceed 60C for 24/7 usage if you want it to last a while.

Ah OK, I will stick with my 2.4GHz until I either clean my fan or buy a better one

I am happy with a 2.4 though so cheers anyway

Sounds to me like you're on auto voltage and the board is overvolting like mad. A 0.2GHz bump shouldnt result in a 16C increase.

I have set the voltage as I have read a lot on here about the issue. So I made sure I had set both Vcore and the memory voltage.

Additional Comment:

I have set the following the 'Over Voltage' section:

VCore: 1.24375
Memory Voltage: 2.000
1.2V HT Voltage: Auto
NB Core Voltage: Auto
SB Core Voltage: Auto
CPU VTT Voltage: Auto
DDRII Controller Ref Voltage: Auto
DDRII Channel A Ref Voltage: Auto
DDRII Channel B Ref Voltage: Auto

I got advised to keep all on auto apart from memory and Vcore

So do I need to set any of these manually? And to what values?

Cheers

Additional Comment:

I had found a guide and set these - only leaving the last 3 set to auto.

This had no affect on the temperature when clocking @ 2.6GHz

When I run full load on 2.4GHz highest temp reaches 50C max - but when set to 2.6GHz it bumps up to 60C in no time.

Well, bump down the vcore by one notch and rerun the test. If it's stable, then bump down one more and rerun. Rinse and repeat until the test fails. Then you know what voltage is required for stability.

Chances are, temps will fall back to acceptable parameters. A 10-15C temp increase for a 300Mhz overclock is far too much. You typically see that much temp increase when you go beyond 800Mhz to 1Ghz+ overclocks.
