    Re: Overclocking i7 920 - 1st try 4GHz to Windows

    I turned my cpu block (GPZ), temps went down. After 35 minutes of Prime I am 11C lower. I used OCZ Freeze as thermal paste this time. Temps will probably go a little higher if I leave the pc priming for a few hours more but it seems that this is better.

    Yeah I definitely got a nice temp drop with mine as well, can't remember exactly but it was enough that it surprised me.

    Pretty cool to see it's looking prime stable at such a low vcore!

    Re: Overclocking i7 920 - 1st try 4GHz to Windows

    I am planning to try and Prime 2.66GHz (default speed) at <1,00v (with Turbo off?). It would be nice if this works. Maybe 0.9v?

    Re: Overclocking i7 920 - 1st try 4GHz to Windows

    It CAN be lower, see this (no turbo):

    EDIT:
    CPU = 1,00v in Bios (lower would hang the system while priming or booting)
    It's 41C and 262W under load after 40 minutes now.

    Load:



    Idle:




    EDIT: After 4 hours:

    4GHz primed:
    I'll probably lower the voltage a bit if it can.

    Well done - it's rather better than I could manage!

    Re: Overclocking i7 920 - 1st try 4GHz to Windows

    Thanks.

    It's getting really hot at 4GHz, I want to do something about that. I want to prime 3.6GHz now. I want to use it as every day setting.
    You've got a nice system as well. I have 2 WD's as well (raid edition), they are in my media center.

    Next challenge 4200MHz?



    validation

    I guess 4400MHz didn't boot to Windows anymore (1.55v in bios, 1.5 in win?). Maybe 4300MHz will?

    Re: Overclocking Core i7 Thread

    4410MHz boots as well. I will not try and prime 4200MHz or 4400MHz.
    I ran some tests at 4200MHz (included in my Excel file) like PI (1M, 4M and 32M), Sandra and 3D Mark Vantage.
    At 4410MHz I only did PI 1M and 4M.

    EDIT 1: For anyone who wants to know if 219MHz bus boots....yes 219MHz bus is possible with UD5

    I have an empty Excel file as well if someone likes to use it.

    Validation



    EDIT 2:

    And 4515MHz boots as well (to Windows). 4600MHz crashed while loading windows.

    Validation

    PI 1M: 9.282 sec
    PI 4M: 47.986 sec

    Re: Overclocking Core i7 Thread

    ok so I have my system built ocing my 920@3.435 w/78C temps on air my question is how high can I go? I use real temp software and a also this seems like a dumb question how can I upload pics to show how I am doing I am still kinda new.

    Use tinypic to host your pics and copy and paste the link they give you over to your thread/response here.

    Re: Overclocking Core i7 Thread

    I really do not like to run mine over 80c except maybe for short bench runs. All 4 of mine use TRUE and 2 fans push/pull. After I get over 3.9 ghz temps at load with ht on are higher than I care to run for 24/7.

    Do you find this makes a difference? I was debating doing this, just as soon as I worked out a sensible way of mounting the pull fan.

    The TRUE benefits from high airflow, so unless you want one killer loud fan, two is the answer. I already had most of the extra wire clips I needed but you can find them cheap at various e-shops. An alternative is rubber bands.
