Haswell Overclocking Guide [With Statistics] - Page 562

post #5611 of 19603
Because I am a curious nerd, borrowed a watt meter from a professor this morning. During XTU stress test my pc pulled 234 watts max, much lower than I expected.

Max load was during firestrike, around 430 watts. This is with a stock R9 290X and http://valid.canardpc.com/g0nlbc

yea, vccin is vrin, meant to say vcore first then the rest, mind lapse out. need more unique and standard acronym teaching.gif

I did that once too and the watt meter pulled about 440 on my system. Not sure how accurate that was since going to site like http://extreme.outervision.com/psucalculatorlite.jsp it say my computer was pulling around 600-650 watt with my setup.

Pretty sure that site is garbage. My meter is accurate, measuring the power pulled straight from the wall. That site likely forces people to overestimate their psu...

Haswell is actually very efficient, albeit hot. I know that sounds like an oxymorone but don't forget "all things being equal" is not the case since A. you have smaller size (ie more transistors per unit of volume) and the integrated voltage regulator also emits heat that used to live on the mobo. And this is under stress testing. In normal conditions (with C-states enabled and adaptive voltage) its power consumption will further scale down with use, making it even more efficient!

Here is one of the official ASUS OC threads on overcloking Haswell
Quote:
"However, power consumption of the processor is very low. We measured no more than 11 amperes of current draw from the EPS 12V line (about 115 Watts if we take VRM losses into account) from a 4770K clocked to 4.6GHz with 1.25Vcore under AIDA stress testing. This tells us that the high temps are purely a facet of the substrate and process size. Getting heat way from the die quickly is what matters."

and further
Quote:
"To give an idea of how good the power consumption of Haswell is under load; a few years ago I performed similar tests on Bloomfield processors (4 core, 8 thread). At 4.4GHz, Bloomfield pulled 22 amperes of current from EPS 12V (220 Watts or so after losses), that’s over double in comparison to Haswell! Haswell’s power consumption is an impressive improvement for the tech enthusiasts among us.
Quote:
"At 4.6GHz, Haswell’s power consumption is a mere 35 Watts over stock frequency (not including IGP). A 700 MHz return, for a circa 35W bump in power – again impressive."
Quote:
"The kicker is finding a good processor sample. Not all samples will clock to 4.6GHz with less than 1.25Vcore. The voltage variance between samples is also larger than we’ve experienced in the past – luck is needed to land a good sample!"

There are a lot of interesting bits of information there, though some may be a bit conservative or "misinformation". Still worth a read.

Mine pulls 92W at idle and 230W at load (4.2Ghz 1.225v)

EDIT: I forgot that now I have vcore as adaptative, so it was higher then 1.225v (set as base for adaptive)
post #5618 of 19603
I'm stability testing with x264 now with 4.2ghz at 1.163 vcore on my i7-4770k..

I'm at 67-70C using a custom loop(240mm rad and 2 slipstreams slim). I have the loop running with the GPU also.

*crossing my fingers*

You ship your CPU to me, I'll overclock it for you and send it back to you for free.
