    Hi Steve,

    It should not have anything to do with SVID, but I think I know why that happens.

    First, this measurement of Vcore is not accurate on the X boards (excepting the Apex accoring to SL) because there is a resistance the measurement of vcore isn't taken into account that results in a positive vcore offset when current flows through it, the more current the larger the offset, so this became more apparent with the 9xxx processors which draw 50% more current than the 8xxx.

    I believe the SVID issue is due to the way the BIOS sets the LLC. if you turn on SVID, it applies Intel's load-line, which is conservative. I had this happen when I first booted up my Code X and saw I was unexpectedly at 1.5v. If you set the IA DC and AC load- line slope values to .001 instead of auto in the BIOS, this should not happen.
    Well, it is a lot better but still a long way from the 1.168. I also assume you know I have the Apex too.

    Indeed on the Apex. And this is not even LLC=7 I expect., so there should be some Vdroop.

    I also have SVID behavior = Best Case and ASUS MultiCore Enhancement disabled.

    Also, if you are running adaptive with svid on, vcore cannot be lowered below the value of the VID @ maximum turbo programmed into the processor by Intel. Sometimes on a good processor. that VID can be more than the Vcore needed for stability. The only way around that is to use a negative offset or to run manual. Now if you are running manual, which I am guessing you are, I wouldn't think that SVID limit would affect the core voltage, but maybe it does. If you turn SVID off, the chip can't communicate that to the VRM.

    I'm running offset right now, but it doesn't matter if it is manual. The same thing happens. I have a LLC of 5 set. There were a few discussions about this on OCN. Not all boards, even not all Apex boards, do this. That's what makes it strange to me. I have tried it with a negative offset which works OK. I just keep SVID disabled and not worry about it. At 5.0 or higher I always use Manual voltage. I just always leave SVID disabled and don't have to worry about it. I just think some things with these 370 boards is a little strange.

    Hi,
    Yeah doorules and I use adaptive on the negative, not too many others do though that I've seen all on the positive.
    I've personally never disabled svid support to see what it would do
    Would anything but cpu-z show anything to tell what vcore was doing

    Yes try this program its free and I use it a lot

    Hi,
    I use hwinfo
    But I was saying would they still show svid or vcore voltage at all with svid support disabled :)

    I don't believe anything can/will show VID with SVID disabled. SVID allows the CPU to communicate with the VRM, so with it disabled nothing can read VID. At least that's what I think. Core temp can read VID if SVID is enabled.

    Hi,
    Sort of a big leap of faith then with it disabled :)

    Vcore is measured external to the CPU at the VRM. so it can be measured without SVID.

    Hi,
    Thanks yeah I tried it yes all still showed up
    Didn't do anything positive so back to auto it is :)
