Overclock Multiplier During Stress Test

dhamiltongrey · Oct 9, 2014

At Idle, my cpu hovers around 30degrees C and multiplier is x16
With Intel Burn test 64bit on high, temp hovers around 50degrees and multiplier goes between x34 and x43
is this normal for the cpu understress to change from full over clock multipler of 43 to something below that..

i had stopped the test after 4 rounds.. to capture idle at stop. then i loaded it again so you could see multiplier change..

The cpu is throttling. As it senses unsafe operating conditions, the cpu automatically reduces it's operation to regain a safe operating condition.

You have almost 40 degrees of headroom before the CPU should throttle down, it should be fine at 50.

Jameson Clark :

does that mean there is a problem during the stress test..

ive just read that disabling the speedstep in the bios will prevent this from happening.. if the cpu throtteling temp is 95degrees ish then i dont need the protection of speedstep, am i right in that thinking

A lot of people disable safety features when overclocking but be sure you know what you are doing. disabling some features will let you OC more and/or make for a more stable OC but are riskier if you dont pay attention.

Pretty much so yes. What will also happen is that the cpu will run at full speed all the time. The system will consume more power but many OC'ers prefer the full on all the time state. Try running the burn test with it disabled and monitor the temps during a 5-10 pass run of the test. You might also try Real Temps to monitor the temps for testing.

Thanks everyone for all the replies.. looking forward to trying this out.. going to be a great test of the akaso voodoo venom cooler.. ive got a spare brand new unopened i5-2500k sat in a box for a rainy day

have fun

Your multiplier fluctuates because you have not taken full control over it in your BIOS settings the original hardware used to write this guide was a 2500K and an ASRock motherboard.

This guide disables all power saving but yields a rock solid overclock even all the way to 5ghz if you have the cooling that can support that high of an overclock!
