Try 101.

Thanks for the reply. I'll give it a shot when I get home.

Niizz, what you're seeing is something called bclk spread spectrum.
 
One thing I noticed about a lot of EVGA boards is sometimes they do things that you don't have any control over to make it seem more stable (bumping voltages higher than you input, etc). This may be one of those types of things.
 
So what spread spectrum? Every time there's a change in voltage/current an electromagnetic field is generated. This EMF can interfere with other components on the motherboard, electronics, and certain countries have standards that limit the amount of EMF that can be produced by a device.
 
Most BIOS give you an option to disable spread spectrum for overclocking purposes, but EVGA does not allow it.
 
Please note that BCLK is multiplied by the CPU multiplier (also your RAM has its own multipliers and they are affected as well).
 
You said 101 BLCK didnt work. Maybe 5050MHz isnt stable in your setup. Also if you had XMP enabled on your 3200 ram, it also would have got bumped up to 3232MHz, which again may not have had enough voltage.
 
So there's a couple things you can do.
 
Try uninstalling XTU if you have that installed. Although I havent had any issues with XTU that may be it. Also uninstall the EVGA precision X nonsense. That can cause issues if you have XTU installed along with it, and after you install it, the services start up every time you restart your computer and can change your OC on you.
 
If you recently just set up your computer, try going to a restore point before you installed EVGA's OC software.

Ahhh right right, I must have read it too fast and saw that 101 wasn't stable as well as it resetting on reboot.
 
Honestly that sounds like a bug in z390 then. It definitely should preserve your BIOS input even if you unplug the machine.
 
Does the z390 have dual bios? or is that just on the z370s and z390 dark? You could maybe try that, in case one of them got messed up.
 
If its a bug in the BIOS, which is pretty likely, you can try a 51 multiplier instead ;)

I do not. This is a fresh build with just windows. No tuning software at all. All the OC work was done through the Bios and checked with CPU-Z and HWiNFO. Is there someone I should contact or forward this to?

Hey, I did watch the video. It showed exactly what my board was running at. I did many tests using prime95 and at the stock BCLK it would never reach 100Mhz. No matter what the load or what benchmark I put it through. It's not the end of the world but spending all this money I was expecting it to be on point. 
 
It's exactly how you worded it in the other thread "sometimes just under but never over".
 
 

Yeah, I totally understand. Just my OCD getting the better of me. Hopefully it's an easy fix. I appreciate all your insight. Thanks.

With this topic being current here and not just in this thread I find it weird how on point and the timing (no pun intended there) spot on with that GN video

I was going to bed last night when that video popped up on my phone. I watched it and thought the exact same thing... It blew my mind. Haha

Nizz call them and explain that all you are trying to do with that particular setting is get it to hold a true DEFAULT setting
 
 
Nizz what is it doing under load?
Run prime95 to push the CPU and monitor what is going on with either CPU-Z or HWiNFO64. It may be dropping it at idle / no load but when an actual load is there it holds 100

No update here man. After 8 tickets I just gave up. I even sent them a video of the problem and they still think it's an issue on my end with windows. Every time I sent a ticket in it was a different person replying so... it wasn't getting anywhere. I love EVGA as a company their GFX cards are hands down top tier but trying to explain something to them through that ticket system is damn near impossible. Apparently they don't or can't check prior tickets so when replying to one it's difficult to keep them up to to date on what was discussed.

Ended up ordering the ASUS Maximus XI Extreme to replace this one. I tried getting a refund but since I sat on it so long waiting for my 9900k the 14 days were over. It's still an amazing board but I don't have anymore patience for this. Going to try and sell it off on ebay to recoup some of the money. Anyways, best of luck to you guys. I appreciate all the help.

It's was an entirely brand new build. Top to bottom.

You know... I've noticed this type of thing with EVGA a lot. If its something could be identified as something they did wrong (pascal thermal issue, RTX "issues", etc), they're all over it and respond to the community very promptly. But if it something they think is your fault or don't feel like fixing, they stick to their decision to completely ignore it 100%. It's like there's an internal memo system and once "the note" is made, no rep will ever give you the time of day on that issue and you'll just keep getting the same copy/paste lip service from different reps until you give up. Notice how several issues are currently in just this form about z370/z390 and there hasn't been a peep from EVGA about them.
 
I recently bought an cheapo MSI board just to see if I was crazy and expecting too much... LLC works, BCLK works, power saving features work, hibernate works, etc. I don't know why EVGA keeps releasing products that are seemingly untested, even some of these issues that seem so simple.

Not a big deal but this is frustrating me.  If I go into BIOS and then boot FSB is what it is set at if I just reboot FSB is stock.  I am just wondering if this is going to be addressed in a future update?
