Launch of Intel's Core i7-4770K "Haswell" processor may be a month away, but the chip has been in circulation for some time now. An overclocker going by the handle "rtiueuiurei" managed to get an engineering sample of the chip past the 7 GHz mark, 7012.65 MHz to be precise. A base clock of 91.07 MHz, multiplier of 77.0x, and a staggering 2.56V core voltage, unless CPU-Z read it wrong. A single 2 GB memory module was used; no other details were revealed. Core i7-4770K and a fleet of compatible socket LGA1150 motherboards launch around the first week of June.

Holy crap!!! 2.65V???!!! That can't be right, CPU-Z must definitely be reading that wrong, there's just no way a CPU that complex can take that much voltage, not even on N2O :eek:

As for the OC, other current CPUs have reached higher clocks, so unless Haswell has a much higher IPC throughput, I hope this is not the limit of its potential.

Impressive still considering this is an ES.

The question is what mobo can provide 2.65V ???????:eek:

Yup. But let's be fair and forward here... it's a CHERRY-PICKED ES sample...


Pretty nice, but what I'm more inclined to look at is the huge multi vs the downclocked BCLK.

Either a cherry picked sample or just a plane lie. i side with the lie..... Noway can any board handle that voltage and I am sure there is no board that will even come remotely close in the bios settings

Yeah... whatever with these claims (even tho I think the voltage is a display error to begin with). Let's wait for real tests from real people with real production chips... for some real numbers. Especially on AIO water loops and high-end air.

1.62 is a pretty old version of CPU-Z, so likely incorrect reporting considering there are already Haswell OC results that are nowhere near that voltage (albeit not 7GHz)

As you can see from this slightly more in-depth article, 2.65v must have been a mistake as you can hit 6.2GHz on just 1.2v.

Plus for those that were asking this was gone on a ASUS Maximus VI*Extreme Edition.


http://wccftech.com/intel-core-i7-4...ds-including-asus-maximus-vi-extreme-spotted/
Did you see the memory oc's from the article linked:
"Haswell Achieves 3322 MHz Memory Overclock

The most important thing to note is that the APACER memory on the Core i5-4670T rig was overclocked to an impressive 1661 MHz, which means an effective clock speed of 3322 Mhz. This is quiet impressive since these speeds are similar to what we would be looking at when DDR4 becomes standard in 2015.

You can check out the validations below for yourself."

I assumed that at 2.5v, the silicone would just explode, regardless of cooling.

with the same version of cpuz 1.62 which reads Vin instead of VCC, and which seems to be fun with haswell... lol...

Why not update CPUz, new cpuz shows vcore instead.

High clock overclocks are useless. And if DICE or LN is involved it's just pointless. Make a every day 24/7 system and post a high clock. Water cooling is freely allowed. Now thats what i always get impressed about. Ppl who run highly clocked systems 24/7.

While 7GHz may sound impressive, it's just that, a worthless high clock you can't use for anything.

I agree, this happens whenever a new CPU comes out, I can even remember Celerons being overclocked that high under the right conditions. Its pretty much normal with the right equipment.

24/7 overclocks are much more important to me.

I'm 100% for this. On every modern motherboard I've owned in recent years the caps on the VRMs can handle no more then 2.1v. This would make caps on almost any board pop if the VRMs for the CPU ran that high. I'm inclined to say that it is fake or the readout is wrong, but there is no way that CPU is running 2.5v.
