Hi all, this is the RAM I have and I have the Classified K flashed to latest version: http://www.gskill.com/en/product/f4-3200c14d-16gtz
 
I enabled its XMP profile and by default with the voltage on auto it sets it to 1.375 V according to ELEET. Both it and the BIOS report the voltage reading at 1.388 V. I thought to myself, okay maybe the board is just applying a bit more voltage to be on the safe side, so I went ahead and actually entered 1.35 into the BIOS. Still, ELEET and the BIOS report the voltage at 1.388 V and ELEET also thinks it is at 1.375 V still:

 
 
 
I have to set the voltage in the BIOS to 1.325 for ELEET to say it is at 1.35...
 
 
 
 
I'm less inclined to say that it is the board itself because I observed the same behavior on the Z170 FTW I had previously owned. It seems to me that any DIMM voltage entered in the BIOS is 0.025 V less than what it actually gets set to.

    It is only the Beta Version, I am still waiting for the first released version for the X99
    I wonder why the 0.9.2.7 version is also not listed for the X99.
    Now Version 0.9.3  http://www.evga.com/eleet/

    You misunderstood my point. ELEET is not the problem...the BIOS is. When entering 1.35 volts in the BIOS, the BIOS reports 1.88V on the UEFI interface.. It's because the BIOS is actually applying 0.025V higher than what you enter on it. I used ELEET as a check to confirm my suspicion because no matter what I enter in BIOS, ELEET shows it is 0.025 higher. So this means I have to enter 1.25 V in the BIOS for it to correctly apply 1.5V.

    Hello,
     
    What is the voltage reading for your DIMMs showing in HWmonitor http://www.cpuid.com/downloads/hwmonitor/hwmonitor_1.28.exe ?

    I'm not sure which one is my DIMM voltage but this is HWMONITOR with my BIOS at 1.35V for DIMM:

     
     
    Also I went ahead took pictures of the BIOS itself to further illustrate this...If you compare these two images with the images in my first post, ELEET agrees with the BIOS that they are at 1.388V and 1.364V respectively but ELEET thinks the BIOS is actually 0.025 V higher than what I really enter. I don't think this is a bug with ELEET, but the BIOS is adding 0.025V for some reason.

    No use trying that.
     
    I've not found any software available that is able to read and make sense of any of my Z170 FTW boards voltage sensor information correctly.
     
    I assume it's the same for the other three boards if they share the same hardware. What is occurring here with mike's Classified K also happens just the same on my FTW.

    Same here. It has been doing the this on all 3 bios versions. I'm using the latest Eleet, the prior version would not work.
     
    I have my Voltage set at 1.35v in bios, Eleet shows it to be 1.375 in the right column and 1.388 in blue in the left column. it is also 1.388 in bios even though set to 1.35v.
     
    I hope this is not considered thread highjacking...just thought I'd add that there might be others experiencing the same issues....pc seems to be running fine though.

    Thanks for the input guys. And no need to worry about hijacking. The more people that can share their input the better :)

    Mine has been the same on xmp also but no memory issues what so ever even stress testing the crap out of it, not a single error I personally do not think to me it is a big deal to worry about. This is all new tech. so may take some time to catch up on the censor readings correctly?
     
    XMP set to 1.35
     
    Bio's show 1.38
     
    not a worry for me have had no issue or reason for it to be

    Yeah I don't get any errors either, but I just wanted to point out that there is some discrepancy of some sort with what the BIOS setting is and what it actually pushing. If you manually put in 1.325 for the DIMM voltage your BIOS should show it right around 1.35 or 1.36 which is what the XMP is trying to do.

    Is this your current settings manual @ 1.325 for actual reading of 1.35 if so no difference at all?
     
    Ugh you got the memory I wished I would have got lol and if I could go back I would do 2x16gb instead of 2x8

    Yeah, if I put it at 1.325 it reads 1.364, and ELEET will show the setting as 1.35.
    If it's set to AUTO or 1.35 it reads 1.388, and ELEET will show the setting to be 1.375. This is why I believe the BIOS adds an additional 0.025V by mistake to whatever setting you put.

    My Z170 Classified is doing the same thing. Has anyone tried measuring with a multi-meter to verify?

    I realize this thread is a month old but I am having BIOS issues as well with memory and CPU tabs. Check out the screen shot below. The BIOS says my memory is running at 158MHz but I have DDR4 3200 installed, and whenever I try to apply the XMP profile to set it at 3200MHz and 1.35V the system crashes and won't even boot up. Don't ask about the CPU BCLK that's displayed (208.7), because I have no idea. I'm running at default 40x100.

    First thing I would try is updating the UEFI/BIOS to the current version which is 1.08 IIRC.

    Not for the K it's not, we are still stuck at the 1.03 Bios, which he has already.
