Overclocking - Updated!

With six cores and 12MB of L3 cache on a relatively new 32nm process, it's not surprising that we weren't able to push our Core i7 980X too far. At stock voltage I was only able to reach 3.5GHz with turbo mode disabled using the stock cooler. I could get the system into Windows at ~3.7GHz, but not stable without additional voltage.


3.5GHz - Max overclock with stock cooling and stock voltage

Giving the chip extra voltage let me go up to 4.13GHz without sacrificing stability.


4.13GHz - Max overclock with stock cooling at 1.359V

    W3680 will be a workstation hexcore @ 3.2ghz

    Im guessing since its a 3600 series, it will be a 1 x QPI, so it will not work in tandium on a DP board.

    Xeons are uber expensive tho.
    And this one if its gonna be priced like the W3580's is gonna have a price of around 1499.

    :X

    I know the OC's were on stock cooling but being this chip starts out @ 3.33 ghz and having a smaller 32nm size, the OC capability seems very underwhelming. I heard this chip is good for extreme overclockers because they did away with the cold boot bug. This thing probably puts out to much heat for any current air or wc setup to get a good oc out. That being said i dont see replacing my D0 920 anytime soon.

    come to our cpu and overclocking forum.

    Or read one of my comments with a forum link.

    I showed people what it can do on higher voltages, when you take heat away from the equation of being the limited value.

    With the 800 dollar premium over an I7 920, why don't you just build a second 920 system instead!

    I welcome you guys to join our forums.

    You'll see more info on stuff on the OC potentials in that preview.

    Looks like the i7-860 is where gamers and people who run lots of multicore apps want to spend their money. Gamers will save $750 and will see almost no difference in performance.

    Yes, gamers will still be more than satisfied with their i7 920's @ 4Ghz. Especially considering those chips are only $200 at Microcenter these days.

    I just hope the upcoming Xeon CPU's will have more of a mainstream price.

    I think the L4D performance is actually due to the extra cores, as source engine games have n-1 multithreaded scaling. It's been shown to have diminishing returns past 3-4 cores, so a 6% bump for an extra 2 cores makes more sense to me than the extra cache, considering no other games show this level of performance increase

    What happens if you put this 6 core CPU in a non-upgraded bios X58 board? Do you then have the minimal functionality to be able to flash the bios to the updated version? Or does the system fail completely, to even show anything on the video display?
    Just wondering...

    If your bios can not handle gulftown, it will just refuse to post.

    eVGA boards are even more picky. If you somehow manage to get a hold of an A0 stepping gulftown, you can not use the same bios on a B0 or B1 gulftown.

    The b0 and b1 are the retail versions, while the A series were pure evaluation / testing samples.

    Some asus boards should support gulftown without bios updates, however its still recommended u get one.

    And if u guys come into our forums, you will see i pushed one up to 4.4ghz with HT ON, @ 1.388 vcore, so i think my 980X is better then the one Raja has.

    Sorry Raja.. :P
