Whenever I enable the only XMP profile for my memory my computer screen flickers after everything is booted up and running. It gets worse as time goes on. Any thoughts on what could be the issue?GA-Z170X-Gaming 7 (tested on F7 and F8l beta BIOS)i7-6700k (not OC'd)8GBx2 G Skill Trident Z 3400onboard videoAny memory tests I can do to see if it's the memory that is bad?
Hello,The internal GFX shares the same voltage supply as the memory controller so when you enable the XMP you are also automatically over-volting the GPU which needs near default voltages to function correctly. (If you didn't know, the XMP also changes voltages not just timing / frequency)VccSA = 1.05vVccIO = 0.95vThese are default values which the GPU requires but for the memory controller running over 2133Mhz most XMP set these voltages over 1.25v.You will have to choose some values and see if the screen flickering stops but if you go to low your 3400Mhz OC might become unstable. Please note your board will have an offset, whatever voltage you choose it will not run at that, usually slightly over. Eg, you choose 1.10v in the BIOS, applied voltage might be 1.16v.So where to start?VccSA = 1.10v <System Agent VoltageVccIO = 1.10vMight work for both GPU and 3400Mhz.
Okay. I reset everything on the bios cause I had been messing with a few things and wanted to start fresh. Took what ElectroStinz said and also increased DRAM voltage as well. Haven't had any issues so far. Here is what I changed:-XMP set to Profile 1 @ 3400-CPU Vcore should be at 1.265-VccSA = 1.10v <System Agent Voltage-VccIO = 1.10v-DRAM Voltage set at 1.35(but actually changes to 1.36)Works so far. Watched some 2k videos on youtube and computer has been running with this setting for several hours. No blips at all. Ran prime95 to test stability and everything is kosher.Thank you ElectroStingz for your advice.
Legal, is your PC 100% stable at 2133Mhz with no file corruption?
Does memory in theory run faster using 3400 vs 2133. People would think so but really it doesn't. I don't really reply to people with memory problems any more. To me it is away for the MB & Memory Companies get you to buy faster memory.
This is the worst motherboard ever bought in my life. The onboard audio is a joke and no matter the memory that you use, always have problems with instability.I'll never buy anything from gigabyte.

The onboard audio is a joke and no matter the memory that you use, always have problems with instability.I'll never buy anything from gigabyte.I have used two brands of board in the past 20yrs. Abit & Gigabyte. Yes I have tried many others but those two brands have been very good to me. I have been doing this for about 35 yrs. You will have problems with all brands out there. Plus if Abit didn't close I'll still be using them.Yes Gigabyte has had their problems with the 170 series boards. This is just me that really anything over 2133 is a waste of time and money. But people read that WOW my board can run 3400 memory. To me all that is a selling point and that is it. I tried 2400 memory the same memory that I'm running on my X99 board. Didn't have one problem on the X99 board but could never get it to 2400 on my Z170 board. It would only run at 2133. Got 16gb of 2133 and never had any other problem. I sold that computer and the guy loves it.The only reason I run the 2400 is I got it at a very good price plus it is from a review too. I Have bought and sold over 200 review items. http://www.overclockers.com/author/lvcoyote/
