    thanks for adding me,

    any tips on how to increase my clocks?
    it seems very odd to me that my highest overclock is also stable

    i have tried the x20 multi with bclk @ 195 (3900MHz) and was a nogo
    i have tried loosening my timings on ram, still a nogo
    i have tried underclocking the ram, still a nogo
    i cant break past the 3800 wall

    Let me know your voltage settings and dividers and I might be able to help, I trust you are familiar with the various idiosyncrasies of i7?

    I am glad there is a thread like this. I wanted to figure out how to get a lower voltage.

    Also, what temperatures are you getting?

    Will add you both now... Welcome to the club guys! :toast:

    Thats the thing with them D0's often they run higher clocks on less voltage but many seem to be even warmer than the C0's, I got lucky with my C0 I think, she will run at 4gig with HT on at 1.28v and with just my TRUE she never goes out of the 50'sC in OCCT so I run that 24/7, I got her upto 4.2gig last night without even using Turbo with HT on on 1.325V and temps around 70C in OCCT which is well within the margins. I couldnt do those numbers/temps with mu old DFI DK, this new Gigabyte UD4P is very sweet!

    That is some excellent numbers for the "CO" , 1.352v @ 4.2GHZ :rockout:

    got to love the ease at which the Gig overclocks the chips, UD4P rocks

    If one good D0 sample water cooled and given core 1.5V how far it would go ?

    voltages:

    vcore=1.34
    vtt=1.34
    qpi=1.3
    sb vtt=auto
    nb vtt=auto
    ram=1.64

    temps i get with these voltages:(across the 4 cores)

    idle= 29-35
    load= 55-62

    i dont even know what that bold word means :D

    Thanks, I dont suppose you care to share some of your UD4P Bios settings for anything 4.2gig and above, I am struggling to move forward here, I am sure it's not the chip, probably just some of my noobish settings on this new board, anything ya got would be gratefully received!

    That word means the little things that the platform seems to like for stable overclocks, like trying to keep your vcore and QPi volts as close to one another as possible, using the uncore and memory dividers sensibly and remembering that QPI, Uncore, Bclock and PCI-E are all so closely linked on this platform, one subtle adjustment can sometimes make it all fall into place, for example, have you raised your PCI-E voltages at all? If not, raise it a couple of increments along with NB Vtt.

    my NB Vtt is on auto, so im not sure what it is set to, what voltage do you recommend for this.

    and i havnt messed with the pci-e frequency, rasing to 102-103 i can try.
    i have read many places that 1.30 is near the most you should set the QPI, have i been reading bad info, or was that just playing safe. do you reccomend me setting it to 1.34 for my next OC try.

    turbo, should i try to leave this on and get the extra multi's to push my OC past 3800 or no.
    i think no because of stability issues. but you know better than i do, so i will listen to what you have to say on this matter.

    and ya i do keep my uncore double of my ram frequency so the problem does not lie there.

    pci-e frequency and qui voltage i will try to tweek with to see if i can break the 3.8GHz wall i have atm.

    thanks for the help, and thx in advance if you supply more!

    OK, this is just a guess purely because I dont know your motherboard, Firstly I dont mean PCI-E frequency, I mean vtt, does the board have Voltage (not bandwidth) adjustment for the pci-e lanes? Mine does and my last did.

    You mentioned that your NB vtt is set to auto, does it not give you what the ACTUAL setting is in the BIOS anywhere? Often it will be on the Hardware section that shows fan speeds and general voltages? If not, try downloading a hardware info proggie that will give you all the different actual voltages.

    Turbo is purely preference, personally I always attemp to manage a stable overclock first without turbo purely because turbo is just increasing one cores speed in reality according to load only, once you have a stable overclock without it, then try it later for even more speed! Thats just my preference as I said, I dont even really count turbo as an overclock really, again it's just personal because as I said, it's only overclocking (in reality) 25% of your CPU.

    On the UNcore divider, I beleive it's at LEAST double, I have read where some have dropped the memory divider but not the Uncore divider and had some better results, personally I havent but it might be worth a try? Say 6 for ram and 16 for uncore.

    Lastly, sometimes it's just good to go a bit overboard from the word go with VCore and QPI volts just to factor them out of the equation, you can always drop them down if you get a successful boot. Dont forget CPU Pll also, as your BClock increases, you may need a bit more than "auto" juice there also.

    My response is very general with a few things to try purely because I dont know your board and it's BIOS, have you tried Googling the board to find forums with other TPower users and steal their settings to try? I think Xtreme Systems has a TPower overclocking thread for example.

    Lastly (really lastly) if you still struggle with the overclock, try the x19 multiplier, on my last board I had much more stable overclocking success with 19x, on this board it's the opposite.

    I've managed to break 4.4GHz but its only stable for benching!!

    HT off to save some core temps

    Very nice Wet, that V8's holding up well, can you get a Vantage or 2006 run out of that or is it just SuperPI etc? ........ care to share your key BIOS settings?

    Sweet, 9.3 on the superPi, what ram u use and the timings?

    yea i think most of us have our known bench stable settings for our own enjoyment, running it hard to see what system can do, but then have our 24/7 settings that we go home to at night :rolleyes:


    From what i see in your settings, that chip will prob do around 4.5ghz bench stable to a point, tht is a nice OC for the voltage so it should scale very nicely :roll:
    also see you got the crutials that we all stocked up on, sweet, also the DO and a UD5p, Thats a FIRECRACKER thats just waiting to be LIT~! :D

    I like the boards that have the bios memory for saving multi profiles, makes overclocking easier and getting back to the HOT speeds jsut a click away :toast:

    Cheers guys... am at work @ present but will try and post settings when I get home tonight....

    @ Tatty... tried running WPrime after SP and it shut down... so I guess temps got too high!

    @ SV ... no I was using my OCZ Platinum 1600 CL7 for that last run. I just wanted to see if my Crucials were holding me back.... seems they were. I could get to 4.1 stable on Crucial... but this is my highest speed. All RAM settings were set on Auto apart from setting voltage to 1.64V so I really couldn't tell you much about them tbh I don't really know how (or why/when) to change them!

    Edit: yeah I like the fact I can save a base profile then save my Benching and Normal profiles as well.... I think this build is gonna be one of my better builds!

    thanks for the good info so far!
    i wish i got a different board when i was getting all my parts together.

    but anyways, here is some info for you.

    my hardware monitor lists this for my current stock speeds:

    cpu idle temp: 31C
    NB temp: 48C (is that high? i would think so)
    system temp: 33C
    cpu vcore: 1.232v
    NB VCC: 1.088v (it uses the 1.10v settings i think)
    cpu VTT 1.136

    here are the voltages that i can change:
    cpu vcore (duh!)
    cpu VTT (1.2v and up)
    cpu PLL (1.8, 2.0, 2.2, or 2.4....those are the only options, and they all look scary to me! lol)
    dram
    nb vcc (1.1v and up)
    sb vcc
    QPI/PCI-e PLL (1.1v and up)

    now here is something that may or maynot matter,
    with all the voltages that i have set in the past, my boards shows them all still in "green", except for my QPI/PCI-e PLL. the boards shows the last safe voltage for this is like 1.2ishv, and i hit the "red" when i set it to 1.3v and just ignore the color warning.

    do all the i7 motherboards link the qpi and the pci-e via voltage?

    ok, your turn! hehe

    oh btw, the x19 multi is what i have been using, because i struggle with the x20 multi

    Ok, back from work and here are CPU-Z details of RAM:
    [​IMG]
    They are OCZ Platinum DDR3 PC3-12800 1600MHz CL 7-7-7

    BIOS is flashed to F7 and settings are:

    LOL you're right CP I've disabled Turbo Boost NOT Hyper Threading!! lol

    Gonna give it another shot with HT OFF!

    OMG!!!!
