    Default OC EP45-UD3R + E8400 - Bios update wiped Profiles

    Hello all,

    i've been reading "lots" of posts about overclocking with GA boards in here since this is my first GA board. Having an older RAM after some weeks/month i finally made some progress with LSD's Memory tips. I can't remember how stable i got 4 G but i remember not having any probs going 3,8 with stock settings as long as i followed all the tips and not use "AUTO" in bios.

    Now i made the big mistake of upgrading to latest BIOS(F11) and following the guide i set "load default settings" or something and boom all my profiles were gone ! Thx GA , weeks of work just gone. I don't know who to blame maybe myself but anyhow i had to revert back to BIOS F9 because the new BIOS F11 made my PC hum so loud it was unuseable ( yes hum , i think it comes directly from capacitors or maybe AC ).

    All attemps to redo the OC settings failed. Normally i never post in forums i read and gather infos and get the job done but right now i'm really p***** because not the slightest over clock is working anymore ( hardcore test with ET:QW full graphic details crashes after 1-30 minutes ).

    So I'm asking the experts here. The thing is i have this RAM :
    http://www.corsair.com/_datasheets/T...048-6400C4.pdf

    And all the examples / discussion are around faster RAM or 4 Gig rigs.

    Please can someone provide me with settings that would work getting a 4 G OC ? Or at least stable 3,8 , i think my firefox crashes even with 3,8 : (

    I used the most relaxed settings in all memory areas from this post:

    http://forums.tweaktown.com/f69/memo...vs-bios-27283/

    I tried nearly all vcore settings for both northbridge and cpu.
    Maybe i did some basic errors but I experimented with nearly every setting right now.

    Setup :
    MB: GA-EP45-UD3R Bios F9
    CPU: E8400
    Ram: like above
    one 320 gig SATA drive, 2 PCI media cards ( TV + Sound )
    Nvidia GTX260-216 55mm edition
    430W S12 II AC ( I know you people have bigger AC, but if you do the math this should be plenty even when OCing, no? )
    eXtreme Power Supply Calculator

    Any productive help would be much appreciated !

    PS: How dou you guys dump the BIOS settings in that text format ? GNU/Linux version available ?

    Regards,

    Please post your BIOS settings for 3.8GHz OC.
    I have the same RAM without any kind of a problem so far, at their specified low latency timings.
    Also fill your forum signature with your system spec and the link to the ram specs.

    From my experiance with BIOS upgrades, the profiles are useles even if they are saved to a USB drive, and can't be used with different BIOS vers., but can be used as reference if you don't have the settings written somewhere.

    Chike's right. Any BIOS profiles created with an old er version of a boards BIOS, can be loaded and used, but Gigabyte give a warning telling you not to. This is because there may be differences in the settings that aren't user accessible. These settings could cause issues in newer BIOS where those settings need to be configured differently.

    Too late now, but in future it would definitely be a good idea to save the profiles to a USB drive. Even if they beome outdated when flashing to a new BIOS, you can still ignore the warning, load them, write down your settings, exit without saving then re-enter them manually.

    Hi,

    @Psycho101 , thx , i will now backup every profile , although i read during flashing "backup cmos" or something which it did not do or i misunderstood ...

    @Chike,

    I update my sig , which now holds the infos provided above.

    I used the most relaxed settings LSD's advised for P45 from the thread linked above :

    ACT to ACT Delay (tRRD)________ 3-4
    Rank Write to READ Delay (tWTR)_______ (4-6) 9-11
    Write to Precharge Delay (tWR)________ 3-5
    Refresh to ACT Delay (tRFC)___________ 38-42 (2X1GB)
    Read to Precharge Delay (tRTP)_________ 3-6
    Static tRead Value (tRD)______________ (5/6) 7-10 (800Mhz)

    So this brings me to this setup :

    MB Intelligent Tweaker(M.I.T.)
    Robust Graphics Booster ...............: Fast
    CPU Clock Ratio ..........................: 9
    Fine CPU Clock Ratio.....................:.0
    CPU Frequency ...........................: 3.000 ( 3.8 G - 4 G )

    (G)MCH Frequency Latch...............: [333] ( was 400 in all tests )
    System Memory Multiplier ..............: <this is="" a="" bit="" buged="" imho="" right="" now,="">
    only latch 400 + AUTO gives me direct 800 Mhz , so went to 333 , plus the only setting that would give me direct 800 avoiding AUTO, this is new. It worked with some .D setting directly some days ago ... : (

    Memory Frequency (Mhz) ..............: 800Mhz
    DRAM Timing Selectable ................: [Manual]

    Standard Timing Control
    CAS Latency Time........................5 ( i avoided 4-4-4-12 for OC but have it in 24/7 which is from vendor specs )
    tRCD .........................................5
    tRP'...........................................5
    tRAS..........................................18

    Advanced Timing Control
    tRRD...........................................4
    tWTR..........................................10
    tWR............................................5
    tRFC...........................................42
    tRTP...........................................6
    Command Rate (CMD) ....................:2

    ( that does make sense no ? i'm starting to think i will just calculate all those numbers by hand. There are some formulars in this forum for it .. )

    Driving Strength Profiles
    Driving Strength ............................AUTO

    Dimm1 Clock Skew Control...............:Auto ps
    Dimm2 Clock Skew Control...............:Auto ps

    Channel B

    tRD Phase0 Adjustment...................:<<< Leave for all below as well
    tRD Phase1 Adjustment...................:Auto
    tRD Phase2 Adjustment .................:Auto
    tRD Phase3 Adjustment..................:Auto
    Trd2rd(Different Rank)....................:Auto

    CPU Referen.…………....0.755V*.......: auto


    CPU Reference2………,,0.800V*.......:auto

    MCH/ICH

    DRAM

    DRAM Termination .…0.900V............: <<< Leave
    Channel A Reference 0.900V............: <<< Leave
    Channel B Reference 0.900V............: <<< Leave

    So i basicly try to up CPU frequency until 3.8 G - 4 G
    -> up trd 8-11
    -> up vcore
    -> test and fail =)

    Thx for feedback.</this>

    Personally I leave all memory timings on auto.
    leave (G)MCH Frequency Latch auto, instead select the desired multiplier, 2.00D for 400MHz FSB for a start.
    Try CPU Ratio 7.5, CPU Host Frequency 400, CPU Vcore/PLL/Termination manually on default values, MCH Core 1.2-1.24v. See if you can run like that, then start increasing CPU Ratio and apply necessary changes to CPU Termination/Vcore.

    Default Re: OC EP45-UD3R + E8400 - Bios update wiped Profiles

    I'm puzzled again , but positively this time ....
    I'm testing 3,8 G still but with most agressive timings this time :

    CAS Latency Time........................4
    tRCD .........................................4
    tRP'...........................................4
    tRAS..........................................12

    Advanced Timing Control
    tRRD...........................................3
    tWTR.......................................... 9
    tWR............................................ 3
    tRFC...........................................38
    tRTP...........................................3
    Command Rate (CMD) ....................:1 !

    trd 7 !

    And everything is stable so far !
    All other settings are standard by specs for the hardware.

    I dunno how to get higher CPU speeds though , since 3,8 seems to be last stable area, but i'll keep you updated maybe too relaxed timings are as bad as too agressive ones , we'll see ...

    defaukt advanced timings are:
    tRRD...........................................3
    tWTR.......................................... 3
    tWR............................................ 6
    tRFC...........................................42
    tRTP...........................................3
    Command Rate (CMD) ....................:2

    As I said, auto timings would have set them right, not too high or too low and ahould be stable and safe, I see no point messing with them at all.
    I ran my memory at 1066 so it should be ok above 400FSB but not with those timings of course.
