It no longer boots with any thing other than default on ram, after bios update. I updated because original bios was not working properly. I did not buy this board to run default or xmp. I have four different sets of ram. Not a ram issue, board issue.

Other than ram, board funtions as it should., aside from an intermittent incident or 2 of not posting with eist disabled. Which was wonky.

The motherboard has no problem running memory at 3200MHz given that your CPU's IMC is strong enough to do so. At that frequency, manual tweaking of the voltages mentioned by the users above will be necessary. So don't expect your kit to be plug-n-play.

First motherboard I've owned (over 2 dozen) that doesn't boot xmp on auto is the point to this post. XMP is about plug and play.

Your CPU's IMC dictate if XMP will work right off the bat or you need manual tweaking. The motherboard automatically assigns certain values to the different voltages involved. If your CPU is below average, you will need to increase the voltages manually. There is no one size fits all.

How did you make out did you get your ram working with XMP Blackjack?

Fine as soon as i checked what my other z170 mobo was running this ram at on auto.

The idea of a good bios is that it will automatically,correctly, assign voltages in a certain range, based on VID and other component factors.
48/46@1.35v
50//46@1.415v
Doesn't quite fall into category of a weak chip.

What your CPU cores can clock up to is not necessarily indicative of how strong the IMC (internal memory controller) is on the chip. In addition, it is common that the higher you clock the CPU the more limiting it can be on getting the IMC to overclock.

You also seem to miss the point that no matter "how good" the BIOS is, no set values can address every possible scenario. For the CPU cores the auto settings might be able to broad brush voltage issue by over-volting a little. Most folks find the Auto settings over volt and can run less voltage manually. As cores tend to use more voltage the higher they are clocked, the BIOS can be programmed on Auto to over volt a little as a strategy to assist the over clocker. This is NOT so for the IMC. At times to find stability the SA and IO voltages need to be lower. Higher is not necessarily the most common voltage answer. This makes BIOS presets more difficult. And becomes more so the higher your are trying to OC your IMC.

If you are adverse to manually tweaking your system and want Auto to do it all, then you likely made the wrong choice in memory speed or motherboard. Running the IMC 3000 and above is not guaranteed to be plug n play regardless if the memory is speed binned for it. XMP or BIOS Auto functions cannot always address the variability in the CPU's IMC.
