    CPU Vcore I am just about to test with 1.2875v it passed LinX with it set to 1.3500v in the screen above.
    QPI/VTT Voltage 1.255v

    I should think I could get 4.2GHz Prime stable, I don't understand why my chip will be rock solid @ 200x20 with only 1.248v Vcore under load, yet I struggle to find stable settings for 4.2GHz and need to crank Vcore in order for it to pass LinX???

    Like I said, I am about to test again with Vcore at 1.2875v instead of 1.3500v..

    If you guys have any suggestions I would be happy to try them out!

    ::edit::

    I've got some Arctic Cooling fans 12025PWM fans coming on Thursday hopefully, these will be getting used on my triple rad once I setup my WC loop, but I will try them out on my TRUE until I get my HK 3, I imagine they will be better than these Xigmatek fans I have atm, as they have got high static pressure, which should make a difference I've been told..

    CPU Vcore I am just about to test with 1.2875v it passed LinX with it set to 1.3500v in the screen above.
    QPI/VTT Voltage 1.255v - you can raise it, i've ran up to 1.4v, if needed only
    CPU PLL 1.300v (I read that lowering this can help gain stability, I have tested it with 1.800 and 1.860v and it doesn't make any difference to my o/c) - i do 1.8v, too high or too low is bad, I would feel better leaving it auto

    MCH/ICH Auto
    PCIE Auto
    QPI PLL 1.100v (tested this using every increment from 1.100v to 1.240v made no difference) - i would try to leave auto
    IOH Core 1.140v (again played with this right up to 1.240v) try 1.275-1.3v
    ICH I/O Auto
    ICH Core Auto

    DRAM
    DRAM Voltage 1.66v - dont be afraid to go higher, 1.7-1.75v. as long as your qpi/dram voltage is within .45v of this you are ok. meaning Dram is 1.66v, qpi/dram must be at least 1.21v

    see above, I put my response in BOLD UNDERLINED TEXT


    your problem is probably the memory diviver, it gets real hard to keep the divider at 8x at 4ghz and above. Try 6x, probably your issue. keep me posted.

    No problem Patty, I will try out your suggestions to see how I get on.. I have never tried using anything more than 1.66v on the RAM because of the Intel warning thing, but I see lots of others pushing more VDimm than 1.65v, so I guess I should try going for more..

    I will let you know how I get on though, but I am going to bed now, as it is midnight here, and I am shattered!!!

    Take it easy guys.

    Every chip hits a point where the next increment of performance takes a large amount of voltage to accomplish. That is a good sign that you are approaching the overclock limit for that chip.
    It will be interesting to see your result. It is a big drop down from 1.35 to 1.2875. I will be surprised if it works unless you were significantly over volted at 1.35.
    My DO chip requires 1.36 vCore at 4200 and 1.44 to get to 4400 and that is with HT off (on for 4200). Every chip is different.

    This is very true, my C0 did 3.8 Ghz @ 1.292v, then for 4ghz it need 1.36v. 4.2 ghz needed 1.45v. at this point, its better to look for a balance of performance / voltages.

    Well, I finally got 4.2GHz Prime95 Blend Test stable!!

    I have to set Vcore to 1.34v in the BIOS, but QPI is only 1.335v, CPU PLL is 1.300v, IOH Core 1.160v, QPI PLL 1.160v, VDimm on 1.66v and all other voltages are on auto.

    Been running Prime95 for just over 6 hours now, and it is still going, so I would say it is stable, however, I am going to leave it running overnight just to be sure.



    Temps are a little high for my liking, but I'm putting my chip under water in the next couple of weeks, I have got my 120.3 rad, fittings and fans being delivered tomorrow, so the only thing I need to get after that is my Heatkiller 3 copper, and I will be all set to start planning my loop layout, I don't know whether I should use both my 120.2 and 120.3 rad in the loop or not, I will need to have a think about it, and see where everything is going to go, as it might be tricky for me to fit both rads inside my current case, however, I will be getting the Silverstone TJ07 in November to replace my TJ10, so I know that I will have plenty of room in the TJ07 for both rads, and I won't need to hack it up in order to make things fit..

    Nice Blunt, good results, you have LLC disabled?

    Anyone have experience with this batches?

    congratulations on getting it stable bro , temps are ok for now, they don't get that high with nothing else. For now you'll be fine with the 120.3. When you get the TJ07 just add the other rad, and maybe at the time you might want to add your motherboards NB to the loop or something, with both rads that wouldn't be a problem.

    Thanks guys, I just stopped it to double check the BIOS settings were what I posted in that last comment, and everything was right, apart from QPI PLL, it is set to 1.240v, not 1.160v.

    I have dropped Vcore down to 1.315v in the BIOS and I will try running Prime again to see if it is stable there, I saved the previous profile just incase it isn't though.

    I think the main thing with o/cing these i920's is finding the right balance between all the main voltages, because I have tried running Prime with 1.35v Vcore and 1.415v QPI before, and it would crash after an hour, but I have considerably less QPI this time, and Prime ran for hours without any issues, and I have also been browsing at the same time to..

    @phsinc, I have LLC enabled mate, if I didn't I would have to compensate for .09v of Vdroop, so that would mean I would have to set Vcore to 1.39v or something ridiculous like that, I have a 4GHz stable profile with it disabled, but tbh, I don't see the point in having it disabled, lots of guys on another forum I frequent say that it can damage chips, but I asked people here about it, and they said unless I am using xtreme voltages then it isn't going to cause any damage at all...

    I agree, these are very tricky CPU's bro, but after all it's worth it. Glad you acheived what you were after .

    Did you drop the mem divider or you kept it at 8x?

    Kept it @ 8x, I didn't want to underclock my RAM by 400MHz!

    I just tried it with 1.315v, and got a BSOD immediately.. so I have put it back to 1.3500v again, and I will leave it running Blend Test overnight just to be absolutely sure it is stable..

    Once I get it under water I will probably push for more, I would love to have 4.5GHz for 24/7 use, I just hope I get decent temps once it's under water.

    What kinda temps do you think I should get, any idea?

    I will be using these components in my loop:

    Aqua Computer airplex XT 360 rad

    XSPC DDC Pro 10w Pump/Res

    Watercool Heatkiller 3 Copper

    EK FC-GTX280 block and backplate

    With 7/16" ID 5/8" OD XSPC tubing and 1/2" DTek high flow barbs.

    This is the first ever time I will have used water cooling, so I have been reading up like crazy trying to learn as much as possible before I set everything up, so I don't make any mistakes!!!

    I just want to have temps that are below 80c, though I have seen guys with similar WC parts clocked to 4GHz and their load temps don't even reach 70c, and there are guys on OcUK with that Corsair H50 thing getting around 72c at 4GHz, and that thing only has a 120.1 rad, so I imagine using a 120.3 should give much better temps than the H50??

    Well at 4.2 GHz @ 1.256v load is like mid 60's. I have a 120.4rad, check below link to see my components.

    LoL, a quad rad just for the CPU!!!

    I don't think my temps will be as good as this because I will have my GPU in the loop, and I need much higher Vcore to get 4.2GHz..

    I was wondering, would a different mobo allow lower Vcore, or would it just be the same?

    I'm thinking about getting the Classifed at some point in the near future.

    In the past I have had chips on one mobo do 2.8GHz, but then when I got a new board, I wasn't able to get the clocks I could previously, so that tells me that the mobo does play a part in how high you can clock a chip, but I am unsure about the voltages needed.

    yeah I went all out in the rad in case, this rad can handle the CPU and board perfectly fine, and when I get a HK block in the future, temps should improve by 4-5ºc, this block kinda sucks on the i7, but at the time it was one of the few choices, so I went with it, only to discover it's not great on i7's.

    Well from what i've read and seen the UD5 is the most solid X58 board, the classified is nice, but I think your limiting factor here is your CPU.

    I had some time yesteday so I reset my cooler with 2 lines thermal compound method which gave me 4C improvement and new 24/7 overclock.

    3922A415 batch

    CPU - 1.296V (1.328V load)
    VTT - 1.26V
    RAM - 1.65V (1.66V shows in Everest) 7-7-7-20 (8-8-8-24 stock - I love this RAM)
    IOH - 1.1V (1.12V shows in Everest)



    here's my 1M SuperPi

    Nice tight RAM timings, I can only get my Dominators to do 8-7-7-21-1T, can't get CAS7 at all, though I have only tested with 1.65v VDimm, I guess if I were to raise it to 1.70v they might just do CAS7?

    You say you have your Vcore set to 1.296v in the BIOS but it shows 1.328v in CPUZ?

    My board does the total opposite of this, if I set Vcore to 1.275v in the BIOS, it will end up being like 1.263v idle in CPUZ and under load it would be 1.248v..

    I'm very impressed too. I never had Kingston before and always thought they make cheap value stuff. I only got it because OCZ was out of stock and Kingston was on sale (original price $240, sale $149) and I'm so not sorry I did it. I can run it 1700mhz at 8-8-8-20 stable as rock.

    No I set 1.315V in bios, it shows 1.296V idle and 1.328V load in Windows. I think that's a Bloodrage thing. I call it Vjump
