Currently, I'm running +25% (more vdroop). So by running PLUS 25% (more vdroop), I'm actually around LLC2, it would seem. I will have to try -25% (reduced vdroop), I think that will put me where I want to be.
How is it failing? Is it hard-locking, BSOD, or shutting down the test? Not all 9900K are going to run 5Ghz all-core, but at 1.4V pretty much 99% of them will, afaik. Your temps must be out of control at that voltage, or are you running a custom loop? I would disable all the C-states and run it at 100% until you find a stable setting. I'm not going to lie to you, the Hero is a pretty awful motherboard. I had one before I replaced it with this EVGA Dark, and it was a PITA. After watching the videos of the VRMs from Buildzoid and how ASUS sacrificed quality to make more money with almost every board in the Maximus line, I will be avoiding Asus for a while. The power delivery on the Hero is ****. I had a lot of issues overclocking memory that I just don't have with this Dark.
What are your VCCIO and VCCSA voltages set to? I would set the RAM to straight XMP if you haven't already and work from there.
There is definitely an advantage to running 5Ghz all-core. The numbers don't lie, and you can see the difference in games as well.
I mean either something is going wrong or I've got the worst i9-9900K to date.
So to answer your questions:
-It either BSOD's or just restarts and boots to Windows on its own. I've had P95 randomly crash after an hour of benching too, which I read is also a sign of instability
-I'm running on air via a Noctua D15 - served me well and idle temps sit at around 25-30c; all of that element seems fine
-I don't want to disable C-states as in the long run I want the CPU to be throttling; I want to ultimately be on an offset configuration; regardless, I've had issues with C-States also disabled, so I've ruled that out as a possibility too...again, do say if I'm missing something here.
-It is set to XMP, the rest is on Auto, as per most guides I've read/watched
I've had an idea - could it be BIOS related? I'm on the latest BIOS, and a quick google seems to indicate some have had issues with it...I've now rolled back and going to run benches on STOCK (Asus multi disabled, intel forced) + XMP only.
If this now fails, there's a hardware problem...
As for the OC, but we're speaking 0.2-0.3Ghz right? On 6 out of the 8 cores; at which point this will only impact a very minor number of games - I'm just trying to get my head around it all.
I remember I had the same sort of thoughts with my 3770k: could have it run at 4.8GHz at very high temps, or run at 4.5GHz at much lower/acceptable temps. The difference in synthetic benches were minimal and were near non-existent in BF3/BF4 benches I did back in the day.
