    Have try to raise cpu vcore to 1.4V and lower cpu multiplier to x24 (now i'm on 135 BLCK) - no luck, stability of getting 0x124 is exactly same...

    Failure13, You should be able to run memory at spec. On my X58A board I run my memory (24GB's 2000MHz's) 2016 MHz with no problem. Thats with QPI/vtt @ 1.395v - never go over 1.40v for 24/7 use - it will fry your mobo. Short benching sessions is OK. Your CPU should not need near the voltage your throwing at it. 1.30v to 1.35v should be plenty. Never run turbo boost - I read where it fried cpu's in another forum. Did you load "optimized defaults" before you started your OC ? I see many problems with your BIOS settings - too many to list - here's what you may try.

    Hi, thx for your answer, there is something new to work with now!
    Failure13, You should be able to run memory at spec. On my X58A board I run my memory (24GB's 2000MHz's) 2016 MHz with no problem.
    O_O !That's...kind of amayzing!Awesome system you got man!
    But i can see you have unlocked extreme processor + watercooling, but i still got very good, but locked one...Maybe here is the differenece.
    Also you got better motherboard, it's specs says 2200mHz+ memory support, mine max is 2133 mHz...
    When i was on G Skill forums they said that i was unable to launch 2133mHz coz i've bought 3 different packages of memory, but i've needed to buy 1 pack of 12 Gb (but what i've bought is ONLY option in my country, so...), And besides, since it perform with 2133mHz on stock settings just perfect with 8Gb, i thought why couldn't it go for 12 Gb? But i wasn't able even to boot through bios post even once to see more than 8 Gb on 2133 mHz. So i really don't know about my particular case :( Hopefully you're right! This is my dream :)
    Thats with QPI/vtt @ 1.395v - never go over 1.40v for 24/7 use - it will fry your mobo. Short benching sessions is OK. Your CPU should not need near the voltage your throwing at it. 1.30v to 1.35v should be plenty. Never run turbo boost - I read where it fried cpu's in another forum.
    Ok, i will keep in mind about QPI/VTT, have set it now to 1.395 V for test, but i have also heard about 2 type of people, those who keep low QPI/VTT and memory voltages, and those who have extreme values but with one rule "QPI/VTT must be within 0.5 V range of DRAM V, other than that is harmfull". I believe i found it on i4 forums somwhere like here Asus X58 + 6/12GB memory overclocking - detecting less memory than installed - i4memory.com - different look at memory
    About CPU - thx, that is a good advice i belive, i was just raising CPU voltage to try gain stability, but as you can see this haven't gave me stability at all...So, since you said - i'll keep at 1.35 now!
    Did you load "optimized defaults" before you started your OC ? I see many problems with your BIOS settings - too many to list - here's what you may try.
    Yes, i am using optimized defaults as base, everyone was asking me about this, but i cna't understand, why? How you define that? Something specifical goes off?

    Now our bios settings is pretty similar, but i got few questions:
    Performance Enhance ..........................[Extreme]
    This settings always gave me only instability, and actually a bit lower perfomance compared to standart, which is strange...but it is for my system. Have you try to compare any bench results like AIDA64 with those settings fro yourself?
    DRAM
    DRAM Voltage 1.500v ...................... [1.660v]
    DRAM Termination 0.750v................... [0.830v]
    Ch-A Data VRef. 0.750v ................... [0.830v]
    Ch-B Data VRef. 0.750v ................... [0.830v]
    Ch-C Data VRef. 0.750v ................... [0.830v]
    Ch-A Address VRef. 0.750v ................ [0.830v]
    Ch-B Address VRef. 0.750v ................ [0.830v]
    Ch-C Address VRef. 0.750v ................ [0.830v]
    But thhis is more serious...Well, i suppose you have already read what i have written about 1.660 v in my case?
    Oh, and when i set dram on 1.66 it sensors of motherboard show actual 1.62 V, and it can't even boot to windows properly..So i stick with 1.68, which shows actual 1.64 V
    BUT i have newer ever touch DRAM termination and CH-* Data / CH-* Adress!
    Probably this is the key?
    Could you please kindly explain what it is exactly, how to use it, how far can i go with those values?
    I'm very interested!
    Guys on GSKILL forums said that i shouldn't touch this values, when i asked them what it is, as i remember...
    At default, with optimizedthose values was always 0.750 v for me, but i suspect this could be key :)

    P.S. When i set exactly your listed settings - 2133mHz of course as always sees 4 Gb and cash after post :(
    When i try your settings with BLCK 143 mHz, x14 memory (= 2002 mHz), x24 uncore - it gives me crash on Windows boot, or few seconds after Windows boot.

    Man, I forgot the 970 was a locked cpu. I never had a locked cpu and will help you if I can. Since you didn't buy the 6 dimm memory kit - you may never get it stable. I set my DRAM voltage to 1.66v (BIOS shows 1.64v) - never been a issue for me. DRAM Termination is 1/2 DRAM voltage. CH-*Data / CH-*Adress is the same as DRAM Termination. You can set to Auto and BIOS should adjust settings. I don't mean to be going backwards here - I would try to get stable using 3 dimms (6 GB's) memory installed in the white dimm slots. That would be a good starting point to see if your going to be able to run RAM @ spec. Bench test until you you achieve the lowest voltages you can and still remain stable. Then your voltages will be only 1 or 2 ticks off running 6 dimms. (12 GB's) Thats what worked for me.
    I like tweaking on my rig - I never set any BIOS settings to Auto for 24/7 use. That took me weeks of testing to achieve. When Benching: For me to run 4.8GHz to 5.0GHz + I can only use 12 GB's (3 dimms)of RAM and have to set some settings to Auto. I even have to set RAM timings to Auto 9-9-9-24 -2 even though RAM timings are 8-9-8-24-2 @ spec. I never change RAM voltages - I keep it @ 1.66v even @ high OC's. I'll help you if I can - Like I said - I never had the chance to use a locked CPU.

    Actually you already helped me like no one did in 2,5 years!!!
    DRAM Termination is 1/2 DRAM voltage. CH-*Data / CH-*Adress is the same as DRAM Termination.
    This is golden rule which i never knew before!!!
    You can set to Auto and BIOS should adjust settings.
    And this is lesson for all of us - newer trust goddamn automatics, on auto it was ALWAYS 0,775 V, with any condition and memory or QPI/VTT voltages!
    This was pretty setious undervoltage for such memory!

    Now i'm running this settings:

    And i have been able to survive 20 minutes of OCCT with low data rate, and have played GTA IV for 1 hour 20 minutes without BSOD!!!!!

    This is very very good result already, i'll have to test it more, but it's a great help!
    Ok, now i would like to shift myself closer for 2000 mHz, if i'll set BLCK 143 mHz, what i will need to add to be stable? More vcore, right?

    so it was dram termination too low? i keep forgetting your using a 6core and not a 920/4 core cpu,those chips can run lower qpi/vtt compared to the four core cpu's,the uncore freq can be lower than 2x ram multi aswell,this will help

    Default Re: GA-X58A-UD7 rev 2 memory / uncore OC stability trouble.

    Well...I can not say yes yet directly, but definately it changed a lot, now i can go for lower QPI/VTT and higher uncore frequency.
    And yes, i perfectly know that 970 6 core CPU can go lower than DRAM / 2, but don't forget taht the goal of my OC is:
    The Goal of my OC is to have completely stable 24/7 system with one of those:
    1. BCLK 143 mHz, uncore at least x24 preferably x25-x27, x14 memory multiplier = 2002 mHz memory.
    2. BCLK 138 mHz, uncore at least x25 preferably x26-x27, x14 memory multiplier = 1932 mHz memory.
    Yet - i can run stable 2, but with 1 (143 BCLK) i need more extreme QPI/VTT to run at least x26 uncore.

    Now i use 140 mHz BCLK, x26 uncore, 1.455 V QPI/VTT, 1,38125 V CPU Vcore, 1.180 V IOH core.

    So far - pretty stable, will have to see how it will be after stress tests...

    Default Re: GA-X58A-UD7 rev 2 memory / uncore OC stability trouble.

    I found that on higher than 136 BCLK when i set DRAM to 1.66 V (mb bios sensor, and all possible voltage measuring software all shows actual 1.61 V) - it's seem to be not enough (according to perfomance at least, especially it's noticeable in video games).
    But when i set next notch (sadly my motherboard's next is already 1.68 V, huge leap already for such sensitive hardware as memory.. (actual reported as 1.645 V which ~ = to my dram spec of 1.65 V), so when i set it, everything seems to be allright, but after few hours under heavy load i can get 0x124, my guess - is that it's operating normally as it should, but in some cases it overvolts a tiny bit - and this leads to crash.

    Question is - considering what i have said above, if i will raise DRAM termination's and vrefs voltages 1-2 nothces more than DRAM / 2 value, won't it improve stability of memory?

    P.S. Oh, and also i found that if you use 143 BLCK on my system (= 2002 mHz memory) - it's utterly impossible to detect whole 12 Gb without setting 1.68 V DRAM on my system...
    Going beyond 2002 mHz seem to be impossible at all. I was trying to add QPI/VTT 1.515 V and higher vcore, without luck. Always sees either 4Gb either 8Gb, but not 12.
    So my maximum reasonable DRAM frequency is 2002 mHz.

    So still, anyone got a clue of why when i play GTA IV with overlcoked memory - i got noticeable effect of, which i can describe as: "ingame objects appear too close / right in your face"...?
    In theory if you up voltage somewhere - then somewhere it can go down...But where should i look? What should i try?

    Please help me to solve this guys!

    This is the case for I'd say 90% of the x58 population and it's up to your CPU if it'll let you play any higher...
