**EDIT** I just found some of the Turbo options are nested, and are a lot more than they used to be. Attaching those pictures on here as well
First, I thought about adding this to the Z390 Owners thread that is epic in size, but it starts out with a Z390 AORUS Master pic and specs, so I wasn't sure if this qualified. So, new thread it is!
Here's the rundown of my setup:
MB - Z390 AORUS Ultra flashed to F10b BIOS
CPU - i7 9700K
RAM - 32GB total - 4x G.Skill TridentZ RGB DDR4-3200 F4-3200C16-16GTZR
GPU - PNY GTX1060 6GB (yeah, it's time for an upgrade
PSU - ThermalTake Toughpower Grand 750W RGB
I bought my current setup Jan 2019. I'm assuming based on when I bought it, it came loaded with F5 or F6 BIOS. I was able to (pretty easily) get it up to 5GHz, RAM overclocked, GPU overclocked, passed Prime95, AIDA64, RealBench, the works. I played some games, got busy with work and life, and stepped away for a little while.
Sometime during this slow gaming period of time, I flashed the BIOS to F9, and then most recently to F10b. I still got on it to do the adulting things, like paying bills (don't let anyone fool you, the i7 is key here for best bill-paying action)
Fast forward to this past week when someone asked to look at my OC setup. I didn't realize it, but all my OC profile had been wiped (probably during the BIOS flash), my RAM was back down to being clocked at 2100 (XMP disabled etc). And, of course, sometime since I set this up last time in Jan 2019 and this most recent BIOS, just about every menu has switched around and changed. I read all kinds of forums talking about the horrors of F8 and what that did to overclocking, VCore, etc. Also, all my saved profiles from when I was testing this out before are now gone. I am guessing it's due to the UI change for the newer BIOS where none of the menus seems to line up.
Anyway, I took by best stab at changing things back to what I remembered them to be (And what some pretty in-depth forum searching came up with!).
Prime95 small FFTs with no disabled options (or, even disabling just AVX2 but leaving AVX enabled) will usually fail in moments with worker 3 expecting something that it didn't get. When reading off Core Temp or HWiNFO64, I'm noticing that, without fail, nearly every time, Core 3 (shows up as Core 2 since the first core is Core 0) only gets up around 25-55% utilization while all the others are at 100%, it quickly drops to around 15%, then of course WHEA blue screen Watchdog stuff crashes everything within seconds. Or, it completely hangs and becomes entirely unresponsive. Same happens within minutes (or less than a minute) of running RealBench, except CPU Core utilization seems to be more consistent (they are usually all at 100%) but it is clearly unstable.
I will say the things that have been tested and tried:
- VCore has been adjusted from 1.30v-1.35v at .05v increments. More stability was noticed at times at lower voltages, and sometimes at higher.
- CPU LLC has been from High, to Turbo, to Extreme when changing to every new VCore voltage. Had some impact, Extreme was less stable, sometime High was less stable.
- Internal AC/DC LL was changed to match LLC on several occasions. No noticable difference.
- Tried with XMP off and running RAM much slower to verify stability is not a result of that.
- AVX Offset was forcibly adjusted to 47 and 48 per suggestions on forums and Gigabyte OC Manual. Still crashes on Prime95 almost instantly and RealBench after a few minutes.
I'm aware there isn't a one-size-fits-all for OC specs, tolerances and all that good stuff. I just feel that I've explored to the extent I am able. Not worried about overheating, not worried about over volting. At the point where I've tried so many options that anything else would be foolish to just guess on with this kind of expensive stuff.
Any thoughts would be helpful
