Intel's Core i7-4770K Overclocked to 5.0 GHz on Just 0.904 V

[rmpumper]

I bet those overclocks are done under idle condition and since Haswell has 10X lower idle power than Ivy Bridge, this means the CPUs will be at close to ambient temperature.

I am expecting most of those overclocking results to get thrown out the window as soon as you enable all cores, HT (where applicable) and give the CPUs an actual workload.

The CPU would be downclocked along with downvolting on idle. As you can see, the CPU is at 5.1GHz, therefore the voltage is load, not idle.

As for the second part, other CPUZ screens show all cores/threads enabled at 5.1GHz 0.9v so I don't know what the hell you are talking about here:

.904V is the voltage taken at the FIVR! That is not VCORE. Get things straight Tom's Hardware! Stop spreading misinformation and posting 3 days old "news"!

So Tom's is wrong because it says "core voltage" and then says ".904v" and they say it has a vcore of .904v because of that?

CPU-Z is currently reading the FVIR as VCORE. Tom's has no idea. This is actually a few days old news...

That's just bad new reporting!

That is impressive. So if .9v at 5ghz is fully stable(lets assume) how much higher can it go with more voltage is the question.

I really want to see the temperatures of these things.

Christian Ney from OCAHOLIC speculated about 5.5 on air, people have already pushed it 7 on all 4 cores and 8 on 2C/2T, if memory serves me correctly.

Between Silvermont and Haswell, I've come to the conclusion that Intel is brilliantly mad. 😀

Calling fake right now. Please prove me wrong.

something is wrong it says 4 cores 4 threads
wasnt the i7-4770k 4 cores 8 threads?
or is it an setup ment to be?

HT is off.

Looks legit http://valid.canardpc.com/show_oc.php?id=2797545 but then again there has been fraudulent entries in the validation database before. I'll take all this with a grain of salt but look eagerly to the results that come out after the 4770k's release.

My body generates more voltage than that. Amazing.

The CPU would be downclocked along with downvolting on idle. As you can see, the CPU is at 5.1GHz, therefore the voltage is load, not idle.

If you disable SpeedStep as most overclock record attempts do - many gamers do so to avoid potential stuttering from clock changes, the CPU remains at full-speed/voltage regardless of load.

So full clock/voltage is not a reliable indicator of actual CPU load.

WoW! good god, I want to see this compare from my 2600k running at 5049Mhz 1.5v w/o hyper junk enabled in gaming benchmarks. This CPU might be an upgrade unlike Ivy from Sandy. Ivy was nothing more than a HUGE let down. GO HASWELL!

 

[amuffin]

Now, what happens if you put this on 100% load? 😉

The 4770k screenshots could have been taken during a low-power state, the same way I took the screenshot above of my 2600k @ 4.4gHz on just .936 volts... I let the computer idle, then opened up Google Chrome, and captured that sliver of time in a screenshot. The chip ramps itself up to its highest multiplier but doesn't need to raise the v-core too much since the load is transitory. 5gHz at .904 is good, my 2600k would BSOD before I could ever get it there... but we should still put things into perspective.

 

[sarinaide]

7ghz on a suicidal 2.56v, now 5ghz on 0.9v. Thanks for the fish but I ain't hungry, this is another fantastic photoshoped effort. I mean 5ghz on less voltage than its stable stock voltages.
/exits another waste of time.

It's not a fake.

I'm impressed, too bad the hex core 49xx series will be ivy bridge. Why must intel make their enterprise cpu's 1 generation behind. I won't be moving from my i7-980x. It's got at least another year in it maybe 2-3.

 

[InvalidError]

Why must intel make their enterprise cpu's 1 generation behind.

Likely so they can work out any significant architecture bugs and do that much more testing before risking putting it into potentially mission-critical servers.

That way, they get a whole year of "field-testing" in consumer CPUs by millions of developers and hackers to help dispel doubts that there may still be significant latent bugs waiting to be discovered. No CPU manufacturer wants to be the proud owner of the next AMD's TLB bug or Intel's FP bug type episode... particularly in the server market where liabilities can be much higher than just replacing defective CPUs.

I don't buy it, Id wager a significant bet that the second you put a load on that system it will go down faster than Barrack Obama's approval ratings. It's not that I don't give haswell props for improving on intel's already great efficiency because it did. However ill believe a crazy claim like this when i see it.

Overclocking with Intel always impresses. Here is an overview of an Intel based Dell server PowerEdge R720: https://www.youtube.com/watch?v=wxkjrQ4UbJk

 

[spentshells]

They mentioned an limit of or around 8Ghz because of the multiplier limitations. - Try about 5.5 GHZ Limit. And that may not even be totaly stable in all applications.

5 Ghz on .097V and posting so I would think even when cherry picked so the speeds will high

Wait and see. Only two more weeks to go before reviews start pouring.

Since Haswell has more complex circuitry on the same process as Ivy Bridge, I would not expect substantially better overclocks under normal operating conditions with a real workload applied.

It appears that someone has managed to overclock the i7-4770K to a whopping 5.0 GHz using just a measly 0.904 V.

You all do realise that CPUz incorrectly reports voltage on newer CPU's right? my 2600k when it first came out: CPUz picked up my 5ghz, but it was @ .9vcore as well. needed to use the bundled OC software with my board just as a vcore checker.
