    The ONLY reason i did this is to see if it can be done. I have a spare bios chip that i flash to for this kind of test.

    DO NOT TRY TO REPRODUCE MY RESULTS IF YOU DO NOT HAVE A WAY TO REVERT BACK TO THE ORIGINAL CONFIGURATION. THIS MEANS, YOU HAVE TO HAVE EITHER A SPARE CHIP OR A HARDWARE PROGRAMMER FOR THE CHIP

    Few thoughts

    I've been overclocking a long time, 10 years or there-abouts. Here's my success with SB on the P8P67 pro.

    5GHz is achievable with the right chip, hardware and plenty of patients. The right chip is pivotal. Water cooling is very easy now-days with a contained unit, such as Corsairs H70.

    Don't ask someone else how they did and expect the same results. That's not how it works. Every assembled machine different, if not from the components then the temperament of the components and temperament of the individual involved.

    If your machine refuses to boot, rather than clearing the CMOS, turn off the power, let the board discharge (10 sec max), turn on power, hold the insert key, then the power button. Hold the insert key until you machine boots, go into BIOS and make changes to restore to last known boot configuration.

    Peruse the web.....there are 6 sites I've found that offer good insights into settings.

    Use common sense, but don't get bogged down when you feel small changes (such as voltage or BCLK) can make the difference in your results.

    Last, I have no responsibility for you cooking your equipment.

    Cheers!

    Thanks Bullu$, it was at ultra high, so it did help some to lower it to regular, but still not enough, it still peeks at 1.5 vcore with cpu voltage set to manual/auto or 1.48 with cpu voltage at offset. if I set it manually to something but auto it wont load windows.
    Must be another setting it can use to shave of the last 0.05 vcore voltage or so.. (finding this new generation of bios pretty confusing compared to the older ones)

    I'm running at medium LLC and set vcore at auto+offset. turbo off. (4700)

    What are your settings?


    maybe we could compare our bios settings.

    That some much better voltage settings you are running with.
    The only things I have changed in the bios is the multiplier,bus speed and LLC, the rest are on auto mode. (1305 bios version)

    the 2 first pictures are the current settings, the last one is what I am more or less aiming for which I can get by lowering the voltage in Asus suite II.

    Did u also tried to set bclck to 100 and 50x cpu multiplier? Maybe it's getting more volts because of the higher bclck.

    nope, goes op to 1.54v when I set bclck to 100, 50x multiplier and medium LLC and set vcore at auto+offset.

    Mine goes also to 1.54V at load when LLC set to medium, try a lower LLC.

    If it doesn't go that low with auto+offset+LLC, then u have to set it all manually.

    still a bit to high with regular LLC, and if I set voltage manually for cpu it won't load windows.
    But there seems to be tons of other voltage options so can imagine there might be another way of doing this.
    Would prefer if it stays below 1.45 at max load.

    Maybe u set it too low.

    Check which voltage it uses when set it to regular+offset in the bios. (write it down or something) when u change it to manual+offset ,reboot and check how high it is in the bios.
    U have it set it almost the same.

    or use manual voltage to 1.42+ultra high LLC

    Seems like 32nm is gets easily degraded. My Q6600 was running at 1.475v for 3years and I would still leave it running prime blend / small ftt for 24-48hrs on weekends or when I dont use my PC and it never required higher voltages.

    Im not really sure into those whole degradation with the vcore if its under 1.4500v but who knows Im concerned and afraid about it.. how did the i920/940's cope up with this before?


    @Topic

    A friend of mine using a 2500K cooled with a D14 seems to be having some rough time getting 4.5Ghz to become stable, we both had the impression that 4.5Ghz can even be done with auto voltage on about 99.99% of the SB chips, I think last he tried was Normal voltage and +0.025.. Seems rather high for just 4.5Ghz ?
    He is using the bios 1302 (IIRC) and the P8P67 Pro (B3)

    I had a Q6600 too that ran for years. and then I had a few 930's that were rather poor, one of them degraded on me. the IMC/VTT voltages were killing them. and for SB, I've seen this degredation with no more than 1.43vcore

    4.5GHz should be pretty easy, on a good chip you can do it with like 1.3v or lower, and with a mediocre or bad chip you may need 1.35v, 1.36v or 1.376v load volts. try manual voltage instead of offset until you get a feel for the chip. asus' offset can be buggy. also be sure to monitor the volts in CPU-Z during load. may be dropping too much and need LLC enabled. I think a good "guaranteed" point for most chips @ 4.5GHz would be 1.352vl load, but many will run lower too. mine needs 1.31v w/ 2T memory, or 1.44v-1.52v w/ 1T memory.

    actually, I've noticed the voltage displayed in BIOS with offset is wrong because in the BIOS it doesn't run with turbo multiplier. so, it runs at 3.3ghz or 3.4GHz SVID. so, offsets won't be accurate until you boot windows and check the new voltage with turbo multipliers. this isn't the case for manual voltage of course, it only effects offsets and SVID.

    I didnt even realize that using 1T and 2T command rates can really affect the voltage that much, isnt the memory timings all under vDIMM and VCCIO?

    Im using a gigabyte p67a-ud4-b3 and im not that familar with the asus board but ill let my friend read your reply and this entire thread probably. I think I remember him saying that he is already setting the manual voltage to 1.350 and still got a BSOD in prime blend for less than 4hrs, I'll have to ask him again.

    I noticed on the GB board though from a clear CMOS the command rate is set to 1T.

    it depends on the amount and speed of the memory. 1T at 2133MHz is very rough on the CPU. but at 1600mhz or lower, it should be fine.

    and if he's using 1.35v without LLC, then it's probably dropping way under 1.3v and that's why he's getting BSOD's. try to find out what his load volts are in CPU-Z during prime95. he'll either need to enable LLC or increase the base volts so during load it doesn't vdroop as far.

    On this thread ( http://www.xtremesystems.org/forums/...18#post4844618 )
    Theres no mention of needing more Vcore with 1T @ 2133Mhz with his chip at 4.9Ghz. Maybe its entirely dependent on how strong the IMC is.

    hmm, maybe... although this is my 3rd 2500K, first one had IMC die, 2nd one needed more volts for 1T, and 3rd one i didn't test enough

    so, the Z68 boards are out now. anyone have comparisons between Z68 and P67? do they overclock better/worse? or what. any compelling reason to upgrade?

    From what I have read, the P67 does not support video on the cpu. Z68 also has some "innovative" SSD caching. Looking for the article, but cant seem to find it, will post when it pops up.

    No idea about OC'ing tho.

    The reviews that I have read don't seem to indicate much difference in OC between P67 and Z68. I just ordered a P8z68-v pro from newegg. I should have it tomorrow.

    Is it worth opening a new thread dedicated to overclocking that board or should we post questions/results to this thread?
