    Default Help overclocking a ga-x58a-ud3r r2.0 for i7 950

    I have very limited experience overclocking and I could use some help.

    My system specs:
    ga-x58a-ud3r v2.0
    i7 950 at 3.06ghz, turbo boosted to 3.2ghz
    12gb corsair xms3 ram (6x2gb) using xms profile
    Antec 902 v3 ATX case
    Corsair CMPSU-650TX PSU
    Raid 0 consists of 2 m4 64MB SSDs (128 stripe) with a 1TB WDC for storage
    EVGA GTX 470 overclocked to core 725, memory 1750 (idle 37C, load 72C with EVGA OC scanner)

    CPU sits on idle at 39C, under prime 95 stress test goes max to 63C. CPU core Voltage (From CPUID) sits at 1.248V on idle.

    Also wanted to mention that with my system at idle, CPUid shows my core speed at 3.2ghz, with core voltage at 1.248V. During loading, it would fluctuate between 1.232V and 1.216V.

    I would like to get a stable 3.8GHZ, to 4.2GHZ. How would I go about setting up my bios to do this?

    I have read the guides on other forums and have an idea on how to play with the frequencies, but I have no idea of how to setup voltages for stabilizing system.

    Thank you!

    for 3.8ghz i would leave everything as it is and change bclk to 23x156
    set dram voltage according to your ram,either 1.5v or 1.66v
    set qpi/vtt voltage to 1.39v (may need more if unstable)
    set cpu voltage to normal in cpu voltage list
    if your ram speed is 1600mhz then set spd system memory multiplier to 10x
    set uncore freq to 20x

    Ok, those settings worked for 3.8ghz. Didn't do a long test, just 30min on prime95 and temps maxed at 71c.

    What would I do for 4.0ghz?

    Specifically, how do I know how to adjust voltage? Which voltages are adjusted and why?

    theres only two main voltages you need to focus on,at 4ghz+ or if you run into stability issues you can tweak other voltages but in general the qpi/vtt voltage for the integrated memory controller inside the cpu and the cpu voltage would need to be raised if overclocking,its best to manually set dram voltage according to whats printed on your ram too

    the more amount of ram you have and the faster the speed/tighter the timings the more qpi/vtt voltage you will need,the higher the speed of the cpu the more cpu voltage you will need

    you can now either stay at 3.8ghz and try to gently lower cpu and qpi/vtt voltages untill it starts to blue screen,then raise one/two clicks in voltage untill stable or raise bclk to 23x175 keeping voltages as they are,however with this blck combo you can only run ram at 8x (175x8) which will give you 1440mhz ram speed and set uncore to 16x

    or use 21x191 and use 8x mem multiplier (191x8) which will let you run ram speed at 1528mhz and set uncore freq to 16x

    if you are unstable then you might need a little more cpu voltage,you can either set a fixed amount and cpu will use that amount all the time without clocking down when idle or light loading or look in dvid and set +0.0500v,this will add 0.0500v to you cpu only when its at load/full speed allowing cpu to clock down when idle saving power/heat,your total full load voltage at 4ghz would be 1.248V plus dvid of +0.0500v = 1.298v,you can add more if needed for example +0.0600v ect but keep an eye on total cpu voltage and core temps

    as for qpi/vtt voltage you might need a few clicks more from 1.39v you would need to test

    if you do get a blue screen error try and catch the code followed by a series of noughts, a 101 error code is not enough cpu voltage and a 124 error code is not enough qpi/vtt voltage

    Thank you! That was very helpful :)

    I did the following,

    1. bclk of 175
    2. disabled all power saving features and turbo
    3. multi 23
    4. uncore x17 (x16 wouldn't post)
    5. memory at x8
    6. CPU voltage at 1.3v
    7. dram 1.66v (mine is rated at 1.65v)
    8. qpi at 1.375v

    Booted fine. Idle temp is 43C, which is only 3C more than at stock.

    All my settings check out on CPUID exact CPU voltage, which is at 1.264V. Is that normal?

    Anyhow, on a prime95 test, I got an error immediately on worker 8. The other workers were running but I stopped them after the first error. What does that mean? Which voltages do I have to raise?

    cpu voltage will drop under load due to vdroop,so thats why your seeing 1.264v when you set 1.3v,you will probably need more cpu voltage if a worker has failed,try around 1.32-1.35v

    you can combat vdroop by either setting a slightly higher cpu voltage or enabling llc (loadline calibration) in the bios

    Ok, so I creeped up the CPU voltage step by step all the way up to 1.35V. After the first bump, I had no error with the prime95, but I got a bluescreen after a few minutes. I couldn't see the error codes you mentioned. It was a string of characters and no 124 or 101. Everytime the bluescreen showed up consequently, I couldn't find those numbers. I did notice however sometime about an IRQL error or something like that. I'm not sure of all them were doing that, cause I was too busy looking for the code you mentioned.

    try raising qpi/vtt voltage now,you might need moretry between 1.35-1.42v

    Ok, I did a memtest86+ check on all the ram just to be sure (read on some places that IRQL errors can be ram modules).

    I did the first run on the default BIOS settings (1066hz, everything on auto) and had an error.

    Then I did a run using XMP profile 1 and ran it for an hour with no errors (1 pass completed).

    I have read that using XMP profile 1 is not good and it is better to manually set the ram. Is this true and why?

    Haven't tried above yet, but getting that first error in the memtest scared me into thinking I could have damaged the Ram (even though it turns out I didn't). I will give it a go.

    You won't damage your ram,that's what memtest program is for,it will simply give errors if the voltage isn't enough or it turns out to be faulty ram due to manufacturing fault,xmp is fine to use aslong as it doesnt overvolt the qpi/vtt voltage,you will need to look how much xmp uses and decide to set it manually if you want or if xmp uses too much
