1x me, 1x brother, 2x were friends (they wanted me to put their chips through the ringer)How were you able to buy 4 chips from MC? My MC checks and I can't buy more than one per month !

Those are some crazy high offsets you're inputting. On my P8Z77, with a .020 offset I get nearly 1.3V during turbo loads. I'd be really hesitant to use .1xxxx offsets.......but I guess this varies per board and BIOS. Also, like you hinted at - the thing about offset voltage is that the turbo voltage is unpredictable and involves a lot of guesswork/rebooting, and the non turbo voltages may not be high enough - causing BSODs while idle. It's really tough to deal with, although i'm not sure adaptive is any better in this respect.
And to piggyback on the unpredictable comment....there have been times where I've used offset voltage and the turbo voltage appears to be a certain value during prime (let's say, 1.25V) and then suddenly it jumps way up to 1.4V which causes instability. Ugh. I hate dialing offset voltage in, it's takes a lot of trial and error. Although, it's worth it in the end to prevent electromigration - obviously turbo voltage 24/7 isn't desirable since you're just outputting that much more heat from your system.
Sounds like Haswell is too hot right? Not necessarily. It totally depends on what you want to do with it. If you just use your computer for Prime95, then you're going to live in the 4.0-4.3GHz range due to heat. But if you just play games and browse the web, your temps are going to be fine

Nah, all OCers who haven't swapped out a clock crystal to get an Adaptec SCSI card to co-operate with increased PCI clocks = n00bsyeah, sadly, rookie OC'ers do not know about boot straps nearly as much as they should.

I read an article last night and I just tried finding it again but it compared the real world speed of the last 4 or 5 Intel processors, all the cpu features, gpu, etc and they scored Haswell a F failing grade and recommended buyers avoid Haswell. It was a German website, some of you might of seen the same article. If you have please post the link. Very in-depth article, like 18 pages of tests, games, cad, applications, etc.
Why not comfortable with mid 80s? Just curious - The temps that occur in prime95 or linx will not ever happen under any load, and those temps are actually completely safe and normal.
My 3770k @ 4.7ghz gets temps in that range (mid 80s) with an H100 and it has been 100% stable for around a year. Again, prime 95 temps aren't temps that you will have in any other workload. You have nothing to worry about with mid 80s @ 4.4ghz
Stock Idle -> 28C
Stock Load -> 54C
4.2Ghz @ 1.2v Idle -> 36C
4.2Ghz @ 1.2v Load -> 75C

So if you're using air or mid-range water cooling, you'll just have to decide what kind of overclock you want - One that runs games fine but *will* overheat if you run Prime95, or a "Prime95-stable" overclock that will be much lower.
Until one, or more, games would use something CPU intensive, and then you'd have a toaster.
BTW can Haswell users run this? http://hardforum.com/showthread.php?t=1752444
Disable boost and post your frequency and temperatures.
Well my first CPU I found out was an open box and didn't OC for crap.. It wouldn't even boot into windows at 4.5ghz 1.250V. Got blue screens after the windows logo. I returned it since it was an open box when I got it and probably a return. This new one is 4.6ghz @ 1.25V I am in windows with no problems at all and even fired up prime 95 for a few minutes without issues. I will do more testing of course later but its already an awesome sign this thing is a good chip.
Batch # - L307B236 ..... The one that didn't OC well at all was L307B239
One thing I noticed is even at manual voltage on my board the voltage is still throttling.. I thought it would stay solid but honestly I want it to throttle anyways.. 29C at idle right now with a PHanteks air cooler...
I figure a 4.5ghz Haswell isn't to much slower than my 4.8ghz Sandy Bridge. .
I don't think I want to push for a max OC, so I'm stopping at 4.5 @ 1.20v. Running Aida64 for 3 hours last night never saw above 75*C in a room that's 29*C. I don't feel the need to push any higher since that's a 50% increase in frequency from my old machine, and who knows how much higher IPC. I can't see anything being bottlenecked right now, and I can be happy with what I have.
Looks like you got a real good chip. What is your cache running at?
Im sitting at 4.5 Ghz at 1.275 Volts at 55ish C on average with spike around 62-63c with some quite fans
Fine I guess
Hadn't really messed with it, so stock 3.9. I guess I can try playing with that next, but like I said, I'm pretty happy so far.
@Banshee : F**king hell! Post your batch number!
What utility will give the batch number, didn't think of writing it down before mounting it
Anyone know how accurate the MSI tools / CPU-Z / CPUID hardware montor are for voltage / temp monitoring?
I left the all the voltage settings on my Z87-GD45 to auto and just bumped the multiplier up to 45x on my 4770k from MC. It's running AIDA / Prime stable so far and all the tools say it's only at 1.152v, temps maxed at 68C. Can this be right?
Isn't that on the box?
mine runs stock at that volts!!
it is on the box
Whomper I left the cache on Auto.. I know that if I move it to 45 I get crashes and CPU voltage doesn't seem to help any. I am currently at 1.250V @ 4.5ghz and I think I finally got it stable with DDR3 1866mhz. Soon I will try to start upping the cache and testing for stability and when im done with that I gotta figure out this Adaptive voltage and how to apply a setting that puts it close to the 1.252V I get under load. I honestly don't know how to use the adaptive voltage yet. I figure a 4.5ghz Haswell isn't to much slower than my 4.8ghz Sandy Bridge. Atleast I get some upgrades on the mobo department with better USB 3.0 and awesome fan control.
