    Default i7 930 / UD7 Overclocking advice

    Im hoping i can get some advice in regards to my oc system which i built a week ago. Im good with pcs but new to overclocking so please bear with me.

    My specs are

    UD7 Mobo
    i7 930
    Corsair 6gb XMS3 (9-9-9-24)
    HX1000w PSU
    HD 5970
    Corsair 256GB C300 SSD

    My problem currently is that even though im stable in prime95 (yes my settings could prob be improved quite alot) when i boot the pc up i will

    A. Get no POST bios beep (when overclocked)
    B. 50% of the time will get the "failed overclock red warning screen" and will have to enter bios, f10... then boot into windows

    Ive not had any probs with prime95 at my current settings though know i still havent done half enough settings otherwise id be booting without any warning screens 100% of the time and would have the bios beep

    My current settings:

    CPU CLOCK RATIO [20]
    QPI CLOCK RATIO [AUTO]
    BCLK FREQUENCY [200]
    PERFORMANCE ENHANCE [TURBO]
    EXTREME MEMORY PROFILE XMP [DISABLED]
    SYSTEM MEMORY MULTIPLIER (SPD) [AUTO] Did try at 2:8, reverted to auto for now
    Advanced CPU Features:
    INTEL TURBO BOOST [DISABLED]
    CPU CORES ENABLED [ALL]
    CPU MULTI-THREADING [ENABLED]
    CPU ENHANCED HALT (C1E) [ENABLED]
    C3/C6/C7 STATE SUPPORT [DISABLED]
    CPU THERMAL MONITOR [ENABLED]
    CPU EIST FUNCTION [ENABLED]
    BI-DIRECTONIAL PROCHOT [ENABLED]
    VIRTULIZATION TECHNOLOGY [ENABLED]

    CPU VCORE [1.30000V]
    QPI/VTT [1.315V] (set to auto i can pass prime95 no probs, set to 1.315v i get BSOD)
    DRAM VOLTAGE [1.64V] (Cant select 1.65v)

    Also im a bit confused regarding my RAM latency settings. My corsair ram is rated at 9-9-9-24 but in bios its showing 8-8-8-20? If i look at CPU-Z it shows 9-9-9-24??

    Am confused to if i change the RAM settings manually in bios or ifs actually setup correctly.

    Everything else is left on Auto, QPI was also on auto till today though has made no difference from what i can see.

    Any advice/help appreciated.

    SB,

    these are my suggestions:

    BCLK FREQUENCY [200] <= Start from 180 first, and go up from there

    VIRTULIZATION TECHNOLOGY [ENABLED] <= disable for now
    PERFORMANCE ENHANCE [TURBO] <= change to standard

    CPU VCORE [1.30000V] <= try to lower to 1.28 V or less
    QPI/VTT [1.315V] (set to auto i can pass prime95 no probs, set to 1.315v i get BSOD) <= try to lower to 1.3 V or less
    DRAM VOLTAGE [1.64V] (Cant select 1.65v) <= try to change to 1.66 V

    about the ram, set the timing manually, easy option, with your numbers: 9-9-9-24 2T

    you don't specify the cooler you use, this may be the issue, your system may over-temp very quickly at higher voltages and frequency.
    What are your temps ?

    Good luck, Jure Z.

    What does it do? How likely is it to improve reliability?

    CPU VCORE [1.30000V] <= try to lower to 1.28 V
    As it stands on current settings (i.e. if im not changing anything else) going below 1.30000v results in BSOD when testing in prime95


    QPI/VTT [1.315V] (set to auto i can pass prime95 no probs, set to 1.315v i get BSOD) <= try to lower to 1.3 V
    IIRC the bios doesnt have 1.3v exact

    DRAM VOLTAGE [1.64V] (Cant select 1.65v) <= try to change to 1.66 V
    I know its only a tiny amount but is it safe to run more voltage than the RAM is rated at?

    the BIOS will change your parameters and multipliers very agressively and make your OC system fail




    QPI/VTT [1.315V] (set to auto i can pass prime95 no probs, set to 1.315v i get BSOD) <= try to lower to 1.3 V
    IIRC the bios doesnt have 1.3v exact

    use the closest available value then.


    DRAM VOLTAGE [1.64V] (Cant select 1.65v) <= try to change to 1.66 V
    I know its only a tiny amount but is it safe to run more voltage than the RAM is rated at?

    I would say that 1.66 V should be safe, but it is your call Sir!

    Also, do you have load line calibration enabled ?



    Thanks, Jure Z.

    I did lol

    Only reason ive left it as it is, is becayse 1.66v is highlighted in red, maybe just because its above the rated limit. Not sure

    Also, do you have load line calibration enabled ?
    I believe its on as standard? So yes its on its standard settings



    Thanks, Jure Z.

    Load Line Calibration is not enabled by default, AFAIK...

    1.66 Vdimm is fine, and actually this is normally the only setting that will get you closest to 1.65V. You are fine to use more anytime you want though, just be sure to keep QPI/Vtt within .5 of Vdimm.

    1.64 often only gives you 1.62-1.63V which is why you will often see 1.66 suggested/used.

    Please give me your full settings in a template from my signature and a link to your memory, then I can advise you on best settings for your intended overclock and hopefully solve this failed overclock warning issue for you.

    In regards to Memory speed and timings and CPU-z, be sure you are looking at the right tab. In CPU-z you need to look at the Memory Tab, not the SPD Tab. If you are not setting your memory timings manually in the BIOS then you should, what you see on the left can be ignored as it is not always uses, so you need to set yourself if you want a certain timing used.

    I'll help you more in depth, once you post us your full settings.

    Link to memory. This COULD be a slight prob. I built 2 complete systems, one for me and one for my flatmate. We got our parts from different places, i assumed the RAM was the same but looking at the part numbers now there is:

    TR3X3G1600C9 & TR3X6G1600C9

    Im not sure which is in which machine and what the differnce is between the 2 sets :( Doing a quick search on google it would seem one set is a 3gb kit so im guessing it was just an error in the part number on the website as both kits are def 6gb

    In regards to Memory speed and timings and CPU-z, be sure you are looking at the right tab. In CPU-z you need to look at the Memory Tab, not the SPD Tab.
    Def was the right tab

    If you are not setting your memory timings manually in the BIOS then you should, what you see on the left can be ignored as it is not always uses, so you need to set yourself if you want a certain timing used.
    Dont really understand "timings" so help on this would be appreciated

    I'll help you more in depth, once you post us your full settings.
    Legend, Thank you :)

    Looks like your memory kits different only in the amount, the first model you give looks to be 3GB set and the second 6GB kit. Did you know you bought 3GB and 6GB, or did you get robbed? Sorry, I reply as I read. Are you SURE both kits are 6GB??? You would have to look at installed memory in taskmamager for each kit, or in the BIOS system info page (F9 on the MAIN BIOS Page)

    Before I advise, I need to know for sure which you are using, can you post me a link to where you bought your specific model as well? If so, or not go ahead and post me a screenshot of the SPD tab of memset, then we can see what amount it is and what timings are stock programmed.

    Then I will advise back, sorry for the hassles and delays!
