    Hi Guys, been playing around with the OC a bit more... I have a question on Voltage offsets.
    With direct voltages I settled on 4.2Ghz using VRIN=1.800v, Vcore=1.195v, RING=1.100v and temps on P95 are 69/66/63/61.
    I read up on a couple of other forums, that instead of setting direct voltages, you can set the BIOS to 'Normal' and then play with offset voltages. This allows the system to idle at lower voltages and pushes up by the offset when max frequency is required.

    So I tried this, for the above setting, I set the VCore to 'Normal' which shows 1.100v and then set the offset to 0.095 expecting that the max it will reach is 1.195v under load.
    Before running P95, I could see the board was idling at 0.850vCore. After I ran P95, this shot up to 1.294v!
    Isn't this way to high for the offset I put in the BIOS ? I was expecting closer to 1.20v...

    Edit: Btw, this obviously pushed up the temps now at 76/73/68/65... Still stable though, but not really where I want to be with temps.
    Offset worked good for IB but for Haswell and a Gigabyte board all you need to do is enable C6/C7 in the BIOS and use the balanced power plan in Windows to get low idle voltages.
    For example, I have C3, C6/C7 enabled and this lets the idle voltage drop very low and also easier to sleep. I also have LLC set to Extreme to keep Vccin from drooping.
    With some synthetic testing, using offset voltages can cause the voltages to get pretty high.

    I've got C3, C6/C7 states already enabled in the BIOS and Windows by default is on the balanced plan.
    I' using HWInfo to check voltages, and for 10 mins idle on the windows desktop, the core clock has decreased to 800Mhz, but the Core VID is still 1.192v

    Hmm. Try the Gigabyte SIV utility and see what it says. Is 1.192 your actual vcore setpoint? (vid) if so then HWINFO is not reading it correctly, I suspect.

    I didn't install SIV this time as it was not giving me any benefit over HWInfo.
    BIOS is current set to 1.195v, and I've found the issue with HWiNFO - someone had documented this on another forum topic. I was reading the "Core #n VID" value from the CPU [#n] section - Instead, I should have read the Vcore value from ITE IT8620E section. There it correctly displays between 0.84 - 0.312 !
    I check this via digital multimeter as well, my reading was jumping between 125 to 280mv.

    Thanks Boondocks !

    I'm trying for a 4.3Ghz overclock now.

    HWiNFO is correct...CPU-Z always display max.Core VID (not Core Voltage).

    Edit:
    CPU-Z (blue) above v1.67.0 has also wrong reading with Core Speed and BCLK.
    CPU-Z (blue) v1.67.0 and bellow reading proper Core Speed and BCLK (no SPD reading).
    CPU-Z OC is a bit better (BCLK...OK) ,but still reading max. Core VID and lower Core Speed.

    I also installed SIV - It does correspond to the Vcore value from ITE IT8620E section - Mystery solved !
    Now, onto another strange matter. SIV reports DDR frequency at 1333Mhz, but I have enabled XMP Profile 1 in the BIOS and set multiplier & timings on Auto.
    According to BIOS it should be at 18.67 multiplier - 1867Mhz.
    MemTest 86 shows 933 Mhz (DDR3-1866) and CPU-Z shows 933Mhz as well with 9-10-9-27 2T.
    Is this an error in SIV ?

    EDIT: - Ok, not sure what happened here, but after I restarted twice (to run memtest & change boot order), now in windows SIV shows 1872 to 1886Mhz.
    Memtest 86 appeared to be stable, going to run AIDA Memory stress for a couple of hours.
    Have also decided to keep with 4.2 Ghz and uncore at 4Ghz. Temps are in the 70ies, I don't see myself pushing this to 4.4Ghz.

    If you run AIDA stress test,be sure to set in Preference/General/Memory block size........1 or 2 GB (if not more),to utilize
    your free memory.

    Will do, for now I'm using P95 with 1344K and 14GB Ram (I have 16gb on the system).
    So far I've reached VRIN=1.850v, Vcore=1.210v (had to increase after mem set at 1867), RING=1.150v, CPU=4.2Ghz, Uncore=4Ghz, System Agent/CPU IO analog & digital =+0.200v
    and PCH core=1.150v - Max Temps on P95 are 72/71/69/66.

    I'm currently running RAM at XMP profile at Max rated speed & timings. Is it worth trying to go higher frequency 2133 at CL10 ? or should I just leave it at 1866 CL9 ?

    When you say "is it worth it" do you mean will your system be faster?
    Not really.
    But if you want the experience and just want to try it, go ahead.
    If you look around on the net maybe someone has OC this particular RAM and has some tips.

    Sorry, I should have been a bit more specific with my typical usage.
    I use my system for image processing in batch mode. Usually around 30MB each RAW image - was really slow on my previous Q6600. Due to size of images, I also create a RAMDisk as temporary store during processing before saving to disk. My typical load is around 30-40 images.
    I also game on the machine sometimes - Usually it's racing sims and sometimes strategy - I guess these wouldn't be impacted too much by additional speed.
