i5 6600k TDP question

post #1 of 14
Thread Starter 
So I've been going back looking at pictures of my recent purchase I have made and something seems off with the TDP. I found my max OC of 4.6ghz @ 1.36vcore.


Now I thought the TDP was 91w on the i5-6600k. For some reason, all my hwmonitor pics show 65w-70w at 100% load.




Is HWmontior incorrect or is there something on my board that is keep it from using more power. Specs are in Sig. I have C-states and Power features on right now, this was just a SS after 20 mins Realbench. After looking through my other pics when power saving features are off it's still the same thing, never more than a 70w power draw from the cpu.

Any insight would be nice, or am I just not searching hard enough and this is all this CPU is suppose to have.

use something like prime95 and use hwinfo. hwmonitor doesnt really show any info. hwinfo is also updated for often and you can talk to the author whenever you like to troubleshoot an issue with the monitor

That is just an estimate.

I did reach "93watt" going 1.4v at 4.7ghz but the x264 bsod within 2 minute

For my stable overclock it gives me 88watt estimate in hwinfo64

Okay, hate to bring this one up again...But it still baffles me. I have had the pleasure of thinking I am this skilled computer guy and tried to delid my cpu. Well, I don't know if that one still works but I bent the hell out of motherboard pins. I think I didn't pay attention and glued the IHS on wrong. My mistake, My $500 down the drain. smile.gif

(PRO TIP: If you think you can delid but don't have 100% confidence in your ability, please don't. The chip without the IHS is sitting right here, mobo in it's box with to many pins to think I could ever make it a solid board again)

On to why I bring this post back up. Well, to my amazement I got a solid chip with horsepower still waiting to be unleashed. Currently sitting at 4.8ghz @ 1.3vcore. This puppy can push some power out. And the heat, its nowhere to be found really. After 3 hours of HWBOT Realbench stress testing, 66c steady as she goes. 30 passes of IBT on Very High 72c. However I did upgrade to the Kraken x61, 2 Corsair Air Series SP 140's pushing and the 2 fans that came with it pulling.

So on to this long convo about me destroying a wonderful board and a decent chip, to get some type of redemption with the chip I have now. Why does the Power Draw only show 11 watts. That's it. Never goes over, will drop down to 3 watts sometimes but mainly at 11. The reason I haven't pushed my chip further is because I lack the faith in believing the monitoring sensors are correct. idk.

TDP = thermal design power
This is not the values you're seeing in hwinfo.

you're seeing some sort of calculation of power draw based on values hwinfo pulls.

Sorry, this was my first go with Intel. When I was running amd, power draw was usually near that of the TDP of the cpu.

FX-83* processors pull 200+ watts from the wall when highly overclocked, none of them are near 125w power draw at load, unless left stock.

From what do you get your readings of power draw?

hwmonitor same thing, hwinfo64 same thing and AI suite 3 I think displays power draw. can't remember. idk, it just bugs me cause I'm paranoid about another chip being cooked due to sensors being off.


My 1st i5-6600k 4.6ghz @1.36vcore with a 60ish watts something power draw
My 2nd i5-6600k 4.8ghz @1.3vcore with only 11 watts power draw

Maybe i'm just overthinking this. There just seems to be a huge discrepancy with the 2 6600k's I've purchased and it's throwing me off. One was choking and trying to get stable at 4.7ghz all the way to 1.42vcore. Heat was intense. This new one is just breezing along pushing 4.8ghz @ just 1.3vcore and doesn't show 1/10th the power draw. Nothing near the heat either. Maybe I just had a really really really crappy clocker my first go round, then landed on a solid piece of craftsmanship that still has potential. I'm just lost on the sensor readings thinking there incorrect.

I'd like to stay at the 4.8 since 1.3v is barely pushing above stock settings for vcore. Idk, I just want to some reassurance that hwinfo64 and all the other monitoring software isn't broke. Sorry for the fuss.

The software power sensors are awful, you should ignore them.

"TDP" is the stock power limiter, the amount of power that the CPU will be allowed to draw by default before it throttles away from turbo boost clocks on the CPU and iGPU. This has minimal relation to power draw and isn't a prediction of power usage. When overclocking you are overriding this number and it becomes completely irrelevant.

4.8ghz @1.3v is insanely good for Skylake, like top few percentage of CPU samples IIRC; The 4.7ghz @1.42vcore is about average. 1.42v isn't that hard to cool on a 6600k but the hyper 212 evo is a lower end cooler, it's quite a bit worse than the top end air coolers and stuff like dual-fan-width CLC's.

My 2500k @ 4.5Ghz 1.302V will pull something like 122W in HWINFO. It's supposedly a "close" calculation of the real power draw of just the pure CPU power... you still need to take into consideration the motherboard power draw, ram power draw, etc... I've always wanted a kill-a-watt meter to check...
