Intel "Devils Canyon" Launch - Reviews, OC Info, Availability

[inf64]

There goes the apologist's explanation that those instructions were disabled "because overclocking."

I doubt that anyone who was honest with himself bought that explanation anyway .

Yeah but more than one was quick to trot it out whenever someone would talk about how Intel disabled features on the 4770k "because greed."

Not saying that Intel might not been into artificial marketing segmentation, but 1 year is more than enough to validate TSX for overclocked SKUs.

So that extra year made the difference instead of all the time when they were sampling?

Ask yourself why server and E series SKUs wasnt launched a year ago.

That extra year *on top* of all the time they were sampling could make all the difference.

You mean Intel didnt have the resources to validate two, i repeat TWO SKUs for the original Haswell release ??

 

[Arachnotronic]

His tweets are confusing. It's easy and yet it takes skill to get past 4.7Ghz. Yet 4.6Ghz is done "without a fan". In 1st tweet posted on this page he's claiming it's easy to get to 5Ghz with this thing on air. How stable is it? Nobody needs a chip that can only idle at that OC... After previous PR blunders I'm not taking him seriously until I see reviews.

This.

They had plenty of resources. They validated a couple dozen at least. Your personal SKU wasn't on the list.

 

[tamm]

Basically DC from the various threads around the web is good for those upgrading for the first time in years, but those currently on Haswel and have favorable clocks should be set minus the minority outliers (itch to upgrade, better baseclock)

 

[StinkyPinky]

So still no reviews? Worst launch ever.

 

[TerryMathews]

So then since this was all about validation and not profit, Intel will be releasing a microcode update to reenable those instructions on 4770k right?

Right?

Oh yeah, Intel only uses microcode to correct critical platform flaws like overclocking on non-Z boards.

Assuming that Intel didn't fuse off like they do with their other SKUs, I think that would be the right thing to do.

"Overclocking the Devil's Canyon has been NOTHING like overclocking the multiple Core i7-4770K processors we have used. So if you are going to purchase one of these processors, you might have to ditch some of your old ways of thinking.

Surely we are working on a time crunch here in trying to get an informative report to our readers, but that still does not change the truth. Much to my embarrassment, ASUS' "Dual Intelligent Processors 5 with 5-Way Optimization" auto-tuning process almost immediately got me to a 4.6GHz all-core overclock at 1.32v. Getting into the tuning program and basically maxing out all of the "Digi+ Power Controls" I was able to push the 4790K to an extremely stable 4.7GHz/2400MHz as shown above in the screen capture. Using "manual" voltage tuning does not seem to be the way to go but to rather rely on "adaptive" voltage control with ASUS motherboards. This can however push voltages up higher than you might expect under loads, and you will need to keep an eye on this. It seems that manual mode is working for extreme cooling however. It does however look like to get the same clocks on Devil's Canyon, you will need a bit more voltage than we used on previous Haswell processors. That is a bit flustering considering we were expecting higher clocks at less voltage."

 

[crashtech]

That's kind of weird. I hope that is unique to their test mobo.

As long as it clocks well on fixed Vcore + multi, I'm good.
Don't give a flying Dutchman about wasted power, since I'm usually pegging my CPU at >= 60% all the time.

Have two pre-ordered at the Dallas MC. Can't wait for June 30th to roll around

 

[StinkyPinky]

I think some people don't understand that most overclockers don't care about 5Ghz. Of course it would be nice, but many of us are just mild to moderate overclockers. With the 4790K it seems all but certain you can get 4.5 or 4.6GHz with almost no effort, whereas on the 4770K that was far from certain. To me that is a win.

I think you will get it before the 30th.

 

[ZGR]

I just pre-ordered the 4690k from Newegg. I really hope that it overclocks well!

 

[BFG10K]

At this rate I'll have my benchmarks up before they do. I've tested 65 games on my i5 2500K, I'm just waiting to buy a 4790K.

 

[Unoid]

I was right. It's really only a 200mhz bump hahaha

 

[John Connor]

I was hoping this CPU could overclock to 5 GHz. I'm not waisting $100 more on this and going for a 4670K. Meh.

Seems to be able to OC at 4.7GHz on AIR using the best AIR coolers. Im sure some SKUs will reach 5GHz (or close) with custom WC setups but im not sure they will be stable for 24/7 use.

Edit: I believe the sweet spot will be around 4.4-4.5GHz with the lowest voltage possible. Temperatures (due to higher Voltage) and power consumption are raising rapidly after 4.5GHz and 1.25v.

Time for specifics. Our copy of the Intel Core i7-4790K overclocked gave up using air cooling Noctua NH-D15 to 4720 MHz at a voltage of 1,275 V. It is noteworthy that the low (compared to the Core i7-4770K) operating temperature at the timing and voltage.

For comparison: Intel Core i7-4770K when using the same cooling system and an identical voltage even heat up to 93 degrees Celsius. Even here you can see very clearly the impact of the new heat-conducting material.
But this is not the end. For peace of mind we decided to see how many extra megahertz will achieve even higher voltage. Here, however, we had to use a better method of heat dissipation. To this end, we reached the tea liquid cooling NZXT Kraken X60 . The result? Only 100 MHz more at a much higher voltage, 1.4 volts as high as the Haswell, caused an increase in tension with prolonged annealing temperature up to 92 degrees Celsius. At the same time it was the highest stable frequency, we managed to achieve in such conditions, our copy.
