Low Power usage on overclocked 3930k

post #1 of 6
Thread Starter 
Hi guys I have been overclocking my 3930 for a while now and up to now I havent run into any problems. But I just checked my cpu today just to make sure that all values add up. Now... the weirdest thing happend as I looked at the power usage under prime 95 , running win 8.1 64bit , I noticed that I had a relativ low Watt consumption atleast I thought I had a low one. I am running my cpu @ 4.8Ghz , 1.44Vcc. And I get 166 Watts under full load... now I thought I had a higher reading when my oc was at 4.6ghz , somehow in the 200 ish region if I remeber correctly. Can someone back me up here or have I got an issue with my cpu and its overdue ?


The highest I saw the cpu go was 172Watts......


I would appreciate any input in that manner.


Thanks guys.

There is no software that will read cpu watts correctly in all situations. I'm not sure how accurate readings are with lower power, but when increasing the power draw on the cpu (higher overclock, higher voltage) the software readings don't keep up.

This has been my experience too. I have a 3570k overclocked to 5.0 and none of the software (I have found) with wattage readings will even show it reaching TDP under load...so yeah...grain of salt for wattage reading.

Are you reading the wattage from the wall?

Hi OCmember sorry for the late reply no I did not measure it from the wall. I looked at the generic value over a software programm. CPUHDW , RealTemp. Both had similiar values. I do know that they are not exactly the best way to measure said value. But they do give you a pretty decent picture atleast thats what I thought for a long time (call me novice).

So what you guys are saying is that said tools dont wok properly ? Could I have compatibility issues seeing that the last measurement I took with said programms where on win 7 ? Does the OS change the values that mutch or are they just not set up for win 8.1 ?

Thanks guys for all your responces so far.

ocnmenber had a great idea the best reading you are going to get is one from the wall if you have a amp meter or a kill-a-watt meter this is give you a much more accurate reading than this generic software will.... I would check like this and verify the watts being used.

those tools can not be accurate as they are wrote as generic programs and not for specific boards. they are differences on all boards that can impact the readings you get because wattage is a calculation as you know and not a specific value. to find wattage you have to know 2 values so this is not something a program can give you because of all the differences in all the motherboards. it is just there really for fun and some knowledge but not to be taken as a scientific value, it is just intended to give you a reading probably +-20% or the real value maybe better depends on a lot of factors.


I know this does not tell you what you ask but I hope it will help you anyway... biggrin.gif
