I thought it might be a good idea to get an easy to view list on what speeds the new haswell chips can do. and keep the list in 1 post below so people dont have to read through lots of threads to see what people are getting from the haswell CPU

So if people who have purchased the new haswell can post there stable! max clock speed and voltage needed for this, plus what cooling they are useing. and also if they have delided the cpu.

so somthing like this.

speed 4.4ghz
V. core 1.3v
cooling water
Temp 70c
ICH ON

If useing an air cooler please list cooler used.

Jokester

Can people also say what they are classing as stable, as it can make a big difference, especially ensuring WHEA stable.

So come on guys lets see if we can get some idea of what any purchasers of the haswell chip can on average expect to achive. i will create a list with details in the post below of what each user has achieved with the new haswell CPU

Are those your results vapor matt?

4.4ghz and 70c underwater :0

no they are just an example of how to lay out the results so i can post a list so people can see what haswell has to offer, some might get a golden chip, some might get a poor chip, but we should start to see an average once people start to post there results.
 
not a max overclock but I'll add it since very few of us seem to have haswell

CPU: 4670k @ 4ghz
Vcore: 1.157 (+0.02 over what my d3hp set as default , I never checked if I could do 4ghz on stock volts)
Cooling: shadow rock pro SR1
Temp @ idle: 28c
Temp @ gaming/ordinary use: 48c max
Temp@ full load: 62-64c running AIDA64 stress test (10c above @stock)
BTW my CPU failed the 1.25vcore x46 test

Now, I’ll share a secret imparted by the folks at ASUS who gave several reviewers some tips on overclocking the retail stepping Haswell chips:

Set Vcore to 1.20 V. Set all cores to 46x (which would be a 4.6 GHz overclock), save & reboot. If the system boots past the UEFI and either begins to load or, ideally, makes it into the OS and is stable, you have a 50th percentile or greater chip on the Haswell overclocking-ability bell curve.

If it won’t at least boot there and make it into the UEFI, you probably have less than a 50th percentile chip. You can expect chips in the lower 50th percentile to top out in the 4.4-4.5 GHz range at 1.25 V.

If your chip will boot at 4.6 GHz and 1.25 V, that’s very good. It means you have at least an average chip.

If it will boot at 4.6 GHz and is stable there, then you may have an above average chip.

The best chips will be able to do 4.8 GHz stable at 1.25 V. Our sample did 4.8 GHz, but at 1.3 V and on a custom water loop. Using 1.3 V will likely put a chip out of the air cooling / AIO water cooling thermal envelope. Temperatures in all of these scenarios, from the dog 4.3 GHz chips up to the good 4.8 GHz chips, will always be in the ~90°C range. That’s just the nature of Haswell. With the VRM on-die, think of Haswell as Ivy Bridge plus 10° C.

Theres some rumours retail chips aren't clocking anywhere near as good as ES chips though

Pcpro quotes 4 retailers unable to sell systems above 4-4.2gHz due to unstable clocks. Apparently pre-production chips massively out perform retail versions
 
Not fully stress tested or overclocked but just done the quick screening and continued to up the multiplier. 5 mins in AIDA64.

VCore set to 1.248V in BIOS. CPUID reading 1.26V at full load. Intel Speedstep disabled. Multipler upped to 48.

Intel Core i7-4770K @4.8GHz (49x100)
Gigabyte Z87X-UD3H (F3 BIOS)
Thermalright Silver Arrow & MX2
Temps of high 70's.
Not delidded.

Using same voltage tried x49 but blue screened. :(

Take the lid off that and go for 5GHZ! NICE Chip!

Might look to do this at a later date. Might consider going watercooling at some point, possibly next year, but no immediate plans to take a hammer or Stanley knife to it!

wtf, he had an i920 @4.4ghz as well.

Hehe! Indeed, albeit with HT disabled.;)

Just tried 4.9GHz again but it looks like it's going to need a fairly big jump in Vcore. Got into Windows but blue screened in AIDA64 after about 30 seconds and that was with CPU-Z reading 1.29V. I'm sure there is still a lot to come from this but I'll need to have a look at what all the other voltages mean cos' so far everything is on auto/default apart from the Vcore.
