    Yes Haswell is geared towards power efficiency, so laptops and tablets will reap all the benefits while desktop users will wonder what Intel did with their massive engineering team.

    The only PCI device I can think of are soundcards, but there are plenty of PCI-E offerings anyway its a moot point, unless you are going to reuse your old one in which case you are out of luck. As for the x16 lanes, it has been that way for several years, bridge chips have largely mitigated the problems for people who need extra lanes (a very small proportion which should consider 2011 instead).

    Well the first few results of deleding haswell is in, up to 18c difference! Can still use the vice technique.

    Yep put the chip in-between a vice clap and give it a nice tap with a hammer comes right off. You can youtube it.

    Much safer than a razer blade, especially with the die vrm things. (To tired to remember)

    LGA 115x CPUs have 16 PCIe lanes and the PCH grants up to 8 more PCIe 2.0 x1 links for a total of 24. Almost every 115x board has a PCIe x4 slot fed by the PCH along with additional lanes for USB 3.0, SATA and PCIe to PCI controllers/bridges.

    Native PCI pretty much went away with the 6 series chipsets, and many Z87 boards still have legacy PCI slots provided by an ASMedia ASM1083 chipset.

    I received my i7-4770K batch code L311B404 Malaysia and ASRock Z87 Extreme6. Can't wait to put them in tonight and test, though I think I might partially tear down my 3770K mATX rig to test this afternoon while stuck at work. :D

    Nice post your OC results. Do you plan on Delidding?

    Mine is idling at 30 degrees at stock, haven't tried OCing yet, I'm wary of de-liding and voiding my warranty on a brand new CPU, will try and see how much I can OC (4.7GHz seems to be the upper limit before hitting a thermal ceiling and throttling), will let you know how it goes :)

    4.2GHz, 1.17v, 87c loaded. Good luck getting 4.7GHz at 1.375v without delidding. :shadedshu

    And you're using a Tt water 2.0? That's not very encouraging... I'm gonna post my results as soon as I get back home :|

    Are you gonna de-lid?

    I suddenly felt a lot better about having a 3820. What are you using for a cooler? Hilbert over at Guru3d ran his at 4.7Ghz. Maybe you just got a "meh" chip?

    The problem is, to get 4.4GHz+ you have to go deep into the 1.2v range on these. I could not stop my chip from 124ing at 4.4GHz/1.22v (as far as I went).

    I took my frustration out on my work 3770K. I performed surgery on it and nicked the PCB in a few places, but you know what? It still works! All I did was put a line of Arctic MX-4 from my brand new syringe I got today, plopped the IHS on, latched the socket retention mechanism down, put MX-4 on top of the IHS and put my Xigmatek Loki back on. It booted up fine, and now my 82c chip turned into a 65c one, without Collaboratory Liquid Pro, at 4.3GHz/1.2v. :eek:

    Did you adjust ring voltage when you clocked the multi up? ;) set 1.150, 39 multi for ring, THEN clock up CPU.

    Also, checking stock voltage in BIOS, just on first boot, can tell you all you need to know about clocking ability, anyway. What was yours?

    I'm afraid to delid if I get mine, but it does help temps a lot. How was stock temps?

    Has anyone had any USB 3.0 sleep problems? And I can't remember was it a CPU or MB issue?

    Temps at stock weren't too bad, which is probably why Intel doesn't give a damn about using terrible paste in their CPUs. Temperatures are pretty much the exact same as IBs, maybe a little higher with the built-in voltage regulation. As far as delidding goes, let's just say my 3770K came out okay and I f**ked up the latest gen one. Word of advice: I would not do it unless you have a disposable $349 on hand to throw away. The extra few hundred MHz really aren't worth losing your warranty, resale value and the humiliation of destroying your not even a half day old processor. If the nicks in the PCB didn't kill it, the possibility of your die cracking by bending the PCB too much will. If done right, however, you may be lucky like my 3770K that now does 4.6GHz with ease in the 1.3v range, when it had the same temps at 4.3GHz/1.18v. I probably still need to get Liquid Pro for it as I have no idea how long this MX-4 will last before degrading under the IHS, and replacing it can be a b**** as the IHS has to be lined up properly or your CPU will instantly overheat.

    For those wondering about the whole integrated voltage regulation deal, Intel obviously added that in their chips. If you're wondering why your motherboard still has MOSFETs, chokes and other junk, it's because the board feeds the CPU a single main voltage (user configurable from 1.2-2.3v and then the processor further regulates it from there. Before stupidly destroying my chip, I did play with that a bit and noticed that a voltage under around 1.5v will not POST, and chip package wattage seems to decrease when the voltage is raised. At 1.5v under load it was around ~100w and at around 2.1v it was about 75w. Stock appeared to be 1.8 or 1.9v.

    Since some of you may be wondering what will happen now with my Haswell rig, I hope to get a replacement chip soon and I will certainly not be delidding any more chips until they have lost their value. Stupidity and accidents happen, but I could have easily lost the money elsewhere e.g. a water cooling leak killing half my stuff, speeding ticket, etc. and I will come back from this with the experience I had gained today. But for now, at least I have a slightly faster and cooler 3770K that I can still enjoy for the meantime. Lesson learned. :eek:

    Dave, mine was 1.000V on the first boot, what does it tell you?

    Answered in the Z87-GD65 GAMING thread, but I'll put some more info here, too. 1.000V is "good", but not "excellent". Under 1.000V is the CPUs that we really want for high clocks under air, but up to 1.050 V should be good for 4.6 GHz with tweaking. The chip used in my board reviews is 1.040 V. ;)

    I think mine was around 1.00v as well, but my UEFI only reported the external voltage being sent to the CPU. I tried the 4.2GHz preset which set 1.150v and it 124'd so I increased it to 1.17 which was fine. Obviously I have to get another chip though, but my UEFI on my Z87 Extreme6 had quite a few intimidating voltage settings e.g. Digital and Analog I/O voltage offset, cache voltage, etc. I didn't see anything about a Ring multiplier or whatever, must be named differently on mine.

    I have L309B318(board testing, 1.040 V) and L311B405(memory testing, 1.020 V).

    Might be cache multi since of that label, haven't booted an ASRock Z87 board yet, but soon.

    There was definitely a cache ratio setting in there, and there are also cache override voltage and cache adaptive voltage settings in there too. If you're curious, they are listed on pp 78-86 here: ftp://174.142.97.10/manual/Z87 Extreme6.pdf

    Also, is the "system explorer" with a picture of your motherboard pretty much included with all Z87 motherboards these days? I saw it in mine and remembered seeing it in a review - I think it was your MSI one if I'm not mistaken.
