    HAHA.. noooo.... I hit 5Ghz no problems, but was flaky as hell. ( I did manage to boot to a linux GUI) 4.8 wasn't stable enough for me. To get it more or less stable, I was looking at internal cpu temps of 90+C at full load... way out of my comfort zone.
    so I'm back to 4.7GHz. I tightened up the timings on my memory for a little extra speed.

    I'm already from power on to GUI login at about 10 seconds. (6 if I take out the drive mappings to my windows home server). then another 10 to pull up the full desktop and all the whatnots I have on startup. And a full Linux kernel Build from "mrproper" state takes a mere 80 seconds. :O

    next maybe is a raid 0 on these 2 SSD's :D
    Bu hahahah

    _Why were you flaky as hell?

    Well... it was, like 3am I get a little flaky with no sleep lol

    haha.. yea sorry, It hit 5Ghz no problems, but was flaky as hell.

    hmmm, just reading about my CPU heat. It seems kinda high, even at stock freq and voltage... I guess ivy bridge processors have crappy TIM under the heat spreader?
    I may just have to remedy that. :D

    lol

    OHH, you better watch out with the voltages for Ivy Bridge CPUs! They aren't Sandy Bridge where you can keep on increasing the multiplier until it just BSODs. Plus you saw the temp at 5GHz, 90C with a water block (!!) on the CPU is out of everyone's comfort zone. I've seen reviews that say IB at 1.3V is all that is safe. I've gone above that a bit for a while, but just not worth it.

    As you now see, IB is not quite the OC beast that SB CPUs are. If the big "5.0" is important to you, you'll just have to bite the bullet and live with "only" 4.7GHz. Even that is considered over the top with IB CPUs by many people. That's a good board too, since it did not BSOD at 5GHz, but was just flaky... LOL!

    I'd love to play with all those registers, I've never done Linux since I worked with UNIX at work, I had to have something different at home.

    RAID 0 of SSDs? If I told you how many of those I have with OS's on them, you would not believe me. Actually, I need more OS's, sick of buying Windows licenses. A free one would be unreal... The potential drawback of RAID 0 is you can lose your 4K read speed, it does not scale at all like sequential read, and actually goes down, due to the stripe size. Then you reduce the stripe and your sequential goes down, which really doesn't matter much to most users (from 1000 to 750MBs). It's fun to try it if you use stable SSDs, I've never had any problems using Intel, Samsung, Crucial, and now even OCZ Vertex 4's.

    If I may ask, what would you suggest as a good place to get started in Linux? As in info, etc?

    Oh, and as Prof. Jim says, clearing the BIOS/CMOS is your best friend. If I add any hardware, I clear it. Move SATA port connections, essential to clear. That's one of the main reasons why laptops are such a pain with new hardware, ya can't clear the BIOS!!!

    Yep, I concur. I found any voltage up past 1.35v gave me flaky results. The thermal limit before throttling is 105c, so I do have a little head room there from 90c. Any temp close to boiling water freaks me out a little. haha.
    It seems on IB Intel chose to put substandard TIM between the die and heat spreader. Where on SB it's soldered! There are a few tutorials online that show how to fix this little problem. lol. Like daredevil, I'm a man without fear and will attempt it this weekend. They say a 10c drop at idle and 20+c drop at full load.
    5.0 isn't important at all lol. I just want whatever I can get out of this chip that's going to keep it relatively cool and stable.

    I've heard of a bunch of issues using hardware raid 0, but I'm a tweaker, and won't be happy until I give it a go haha. I might even try a software raid 0 on Linux LVM.

    Hmm a good place to get started in Linux is to download a "Live CD/DVD" and boot it up. Play around with it and see if you like it. Ubuntu and it's derivatives are easy and windows like. The software package WINE will be your new best friend in getting windows apps working under linux.
    There are so many distros it would be hard to list them all. This is a link to one persons take on the top 5

    Best Linux distro 2012: five we recommend | News | TechRadar

    I would like to add two more to that list to make it a top 7 lol
    PuppyLinux: Small, so small in fact it can live completely in RAM (filesystem and all) so it's ridiculously fast. (they say ~100mb)
    Gentoo: My fav, but NOT for beginners. Gentoo is a (more or less) completely compiled distribution. it's portage tree (application tree) is second to none in linux and is based of off the BSD portage tree. Gentoo takes some work getting running and stable at first, but once you got it.. oh my... all software compiled directly for your hardware is awesome.

    There is a Linux forum here as well. I check from time to time, there isn't much activity. We should probably move the Linux discussions there lol.

    Thanks for the Linux info, I'll check it out.

    Why Intel went with standard TIM instead of solder in IB CPUs is a good question. I wonder if the IB die could not survive being bathed in solder, which frankly surprises me that any CPU die could survive that. Or with all the RoHS standards, they can't use solder with lead in it, and the lead free solder melts at a higher temp, which is well known, and the die cannot survive that. Don'tcha love progress sometimes...

    So are you talking removing the CPU heat spreader, and going naked die? That is hardcore, good luck with that. At least it will be easier to remove the IHS without the solder under it, much easier.

    I haven't yet decided if I will go naked die yet or not. But yes, removing the heat spreader for sure. Going naked die will involve having to disassemble the retention clip. The die alone doesn't come out far enough. I also don't want to worry about bending the CPU's PCB as the pressure will be solely on the middle of the chip.

    For what is reported as *maybe* 2-3 degrees cooler going naked die, it's not worth the risk. I'd rather put on good quality TIM on and replace the IHS. Well, not worth it to me anyway. If I could find a suitable shim to put in it's place.. maybe... but there are people out there using just the HSF or water block to hold the processor in... yikes.
    The biggest gain I have read, is in the replacement of the horrible quality TIM Intel chose to use.

    I'm not normally a conspiracy believer.. but I'm beginning to wonder if Intel did do it on purpose. People who have done the TIM change are getting SB type temps and OC's. That makes for a boat load of performance over SB processors. Pretty much every review I read, the change meant at least +100MHz easy on lower voltage.
    it just doesn't make sense... they ALREADY have the Fab process for solder for SB procs. The heat specs are very similar, why would solder on IB melt the core where SB would not? why switch to bad grease and silicone? if it's an issue with solder and temps... at least use a decent quality TIM for Pete's sake. From the vids I've seen, it looks like plaster flaking off the core.

    Well I'll get a better sense of it tomorrow and will report my findings here.

    OH NO! That would SUCK.
    Hopefully I won't be reporting: "waiting for my new CPU arrive" lol

    and hopefully you won't be one of the ones waiting for a new cpu to arrive.

    Conspiracy theory?
    What makes you think that Intel is getting secret payments from the water cooling suppliers?
    .....and they are selling a few more cpu's to the failed TIM surgeons.
