Hey all, I have had issues with my Trident Z 3200 ram ever since I built this rig. At first I could not figure out what the issue was until reading about Vsa and VCCIO voltages for ram that is faster than stock specs for a CPU. I noticed in EVGA E-LEET that my VSA and VCCIO voltages were high when set to XMP profiles. My PC would freeze randomly 2-3 times a day at stock XMP voltages so after reading about VSA and VCCIO voltage settings I lowered mine and each time I suffered a freeze I would up the voltages a little. Currently my VSA is running at 2.38 and my VCCIO is at 1.18 according to E-LEET even tho I have those voltages set slightly lower in bios it always shows slightly higher in E-LEET. OK that being said I still suffer freezes after 3-4 days of constant running the PC.  I am curious if anyone else here is using that ram and if so what do they have the VSA and VCCIO voltages set to. 
My bios is current 1.05 A new bios update to make this ram compatible without having to adjust voltages would be outstanding :)
This rig runs great other than this ram voltage issue and the 3200 ram does make a huge difference in games over 2400 settings.
CPU temps are 25 -30C Idle and 40-45C gaming

    While I don't have a z270 board, I've had that exact kit fail on me in the same way you describe on my z170 Classified K. I also noticed that the RAM voltage setting in BIOS apply too much voltage (for me ELEET would say it was set to 1.375V when XMP and BIOS get set to 1.35V). I believe this is a bug with the z170 firmware and maybe exists in z270 as well. You should test this yourself - set a value for your RAM voltage in BIOS and then check ELEET. See if it will always say it's set 0.025V higher than what you put in the BIOS. So to compensate for this, I manually entered 1.325 for my RAM voltage in the BIOS settings. Whether or not that is what caused my sticks to die over time or if the kit failed on its own I have no idea.
     
    So you can compare, here are my voltages: https://i.gyazo.com/2754fd7f7a3c7cfa768a00f1267231aa.png
     
    Are you sure your VSA is really 2.38V and not 1.38? That is way too high.

    Hey Mike thanks for the reply and info ! I do see your VSA and VCCIO voltages are far lower than mine, were those voltages stable for you? I mean until the ram failed. I love the ram itself, very solid feel and look so would be a shame to have to replace it. I hope EVGA has an update to fix this issue before my ram goes tits up.

    My VSA and VCCIO have always been left on Auto in the BIOS and since replacing my RAM has been just fine. Can you take a pic of what yours show in your BIOS? Also, check this link to see safe voltage ranges (under the Overclocking Instructions section), also image below
