Someone told me that using "Extreme" LLC with a very low + offset, is bad for the CPU.  Is this true?  They basically said I should use a lower LLC, such as "High" and apply a higher + offset.  I always thought that was kind of weird because if you pick a lower LLC and apply a higher + offset, that means your idle voltage will go higher as well.  Isn't the point of using an "offset voltage" is to keep the idle volts low?  If I use a very weak LLC, and add a huge + offset voltage like 0.2v, then my idle will jump 0.2v and thats just inefficient.  The reason why I use "Ultra High" or "Extreme" LLC is because it boosts me much closer to my target vcore....and then I would only have to apply a small + offset, such as +0.02....therefore my idle voltage would only increase +0.02
 
Anyway, is using "Extreme" LLC bad?  Even if your vcore is way under the Intel recommended 1.52v?  He said that using "Extreme" would cause way too much spiking that I would never see...and I should stick with lower LLC's but applying a much higher offset.

    i found on my gigabyte board that the extreme LLC is more for ln2 and hasnt been perfected yet. i run my board on high LLC and have zero issue and its actually a little more stable then the extreme LLC. i found the extreme LLc tends to push the voltage up a bit. not much but the high does not. stays where you set it.
     
    i would try high and ultra high and see where it stays. basic goal is to not have to use the vcore to acheive the same clock. my 3770k will do 5ghz with just a vcore bump and no offset on high LLC through any benchmark you can think of on water. 
     
    also if you have the voltage check points and read-outs on the mobo i would put a DMM on them and find out what your vcore truley is. 9 tims out of 10 the vcore in bios is different then the actual readout from the voltage check point.

    Violence, what is your target vcore using High LLC and no offset?

    I'd leave the extreme LLC for benchmarking when the target vcore is not so important. extreme LLC tends to overshoot generously above set limit in BIOS, not so good for daily running. probably doesn't matter anything at lower clocks and mild target vcore, but could be "that one thing" that adds up over time for high clocks and borderline safe target vcore under load.
     
    if your board supports vcore offset then try that first with Medium LLC (50%) or High LLC (75%) and keep it there daily once stable.
    My current favorite is High LLC with +0.145 offset on 3770K for daily 4.9GHz, rock solid stable. with 5GHz however I can't run offsets anymore as a problem arises with light cpu (e.g. 25%) load eventually (BSOD 124) while everything is rock solid stable under full load, for 5gh+ I use fixed vcore, I switch to Extreme LLC only for 5.1-5.2Ghz, but I rarely benchmark recently, done with that, have barely time for playing games at daily settings

    feniks, what is your idle vcore with High LLC and +0.145 offset?

     
    looks like 1.008v as per cpu-z when CPU idles at 1600MHz.

    Are you using C3 and C6 states?
     
    I'm wondering how you get your idle voltage so low, even with a huge offset like +0.145v

    no, C3, C6 and C-package are disabled, because of RAID0 SSD sakes
    EIST & C1E are of course enabled.
     
    1.008V at idle 1600MHz
     
    under IBT 2.54 load (max mode) at 4900MHz I can give 3 numbers:
    a) lowest observed vcore while loaded up within 1 round: 1.336v
    b) highest observed vcore while loaded up within 1 round: 1.360v
    c) most "sticking" vcore while loaded up within 1 round: 1.352v
     
    that's the thing about offset, it's not linear and it varies between clock speeds (base voltage of it grows the higher the multi) and that layout is hard coded in BIOS. it also seems that idle x16 multi base voltage is different from "regular" 49x multi base.
     
    from own observation of this board (maximus v extreme) I can say that High LLC/ 75% is the most "flat one" and the closest to the vcore limiter number in BIOS when running fixed vcore.
     
    Medium 50% LLC was showing much bigger swings end ending up way below vcore (in offset mode calling for higher offset too logically in order to achieve the same actual vcore as with High LLC under load) while extreme LLC tended to happily overshoot the limiter under full load, forgot the number, but I think it was around +0.03V above vcore in BIOS (tested it with fixed vcore).

    Okay noob question. Though I found it b4 I can't seem to remember where to adjust the llc...
     
     I've looked just about everywhere but can't seem to find it... How the heck can I adjust something if I can't find it.
     
    What is it called on the mobo. First EVGA board and it's confusing as heck. It's got to be staring me straight in the face but I still don't c it...
     
     On the old board it was simple to find. I feel so green right now...

    What board do you have? I Thought this was an older option that newer boards don't use anymore.

    Sorry, thought I had mentioned it b4. I have the FTW X99. I may try to bump it up if I can't figure this out.
     
     I thought I had found it once, but had other issues with the os. Still had the old backup, re installed Windows, formatted the drives, using a SSD for backup.
     
     System atm is as follows:
    EVGA X99 FTW
    Intel 5960x
    Kingston Hyper X 4x4gb 2800 mhz
    Intel series 530 120gb in raid 0
    Kingston E50 enterprise 240 gb for os backup.
    Additional Kingston E50 240 gb for benching software, 3DMark,....nothing too serious, still pretty new to ocing but got to 5 ghz on a 3960 and 4.8 on the 4960, so I think the biggest issue atm is setting the llc to a higher load capability likely high or extreme.
    WD Raptor Drive 500 gb, storage, apps....
    EVGA 980 SC ACX2.0
    LG BR
    Corsair AX1200 not the 1200 i .
    All of this is inside of a Lian Li PC V2120. 11 expansion slots,....modular, removable motherboard tray, all aluminum constr.....Awesome imho. It dwarfs a CM HAF X and is capable of holding a SR-2.
     
     Now I have 2 480 rads with 4 107 cfm fans on each and atm I'm only wcing the cpu. EK gold cpu block, best I could find from multiple reviews. EK thermal paste which came with the block.
     
    Windows 76 Ult 64bit
     
     It works fine otherwise, I can oc the gpu np. I've run all 4 3DMark, 03 Van 11 and Mark.
     
     I'm sure it's something like a simple adjustment like the llc. I did get it to 4.5 once, and 4.14 as well which I managed to run a benchmark. Only ocing I'm getting is from core freq adjust.
     
    It seems the multiplier doesn't work, yet when the core is adjusted it does go up. It will say in the oc section that the multiplier is 45, yet when I check with windows it says 30???
     
     Until I can figure out that issue I'm sol. No hair left, pulled it all out in frustration...LOLZ
     
    Can I step up to the classified if I just got the board days ago??? I wasn't sure about the mobos...

    Yes you can step up to the Classified.

    When you say that your only at 30x in windows is that without a load? Or is that with a load? Also what bios do you have? The X99 FTW i have was shipped with an old bios and when I would save and exit then the Turbo muliplier would say 45 but all the slots under it would revert back to 35 and no overclock was achieved.

    As far as the LLC I believe that has basically become adaptive voltage. But I would set your CPU voltage on manual or whatever its called and figure out your multiplier overclock and max voltage before you start figuring out adaptive voltage.
