Whelp that just happened.
I was watching youtube and the image just cut out. Post code FF. No smoke, no smell, no leaks in loop. PSU checked good.
Tried a different CPU after clearing CMOS and was able to get into BIOS. So my 8700k is dead.
I think it might have something to do with the vdroop issues and voltage spikes I've been complaining about. Setting was adaptive: 1.3V -100mV (to offset most of the vdroop spikes) which usually resulted in voltage about 1.35V under load.
Typically when silicone degrades it goes through the process of deteriorating performance for voltage, and not straight up fried. That's only likely when you get up in the 1.6-1.7V ranges with exotic cooling (LN2, DICE, H2, etc). So I don't think the 1.35V killed it.
So I submitted a ticket to see what they say. I suggest anybody out there still using z370 to reduce their overclock and set vdroop to enable (allow intel spec) until this gets addressed.

I just set the vdroop to Enabled in my Bios and run the same CPU at 4700MHz. What AVX setting in the Bios are you using?

Yeah it should be "enabled" if set to auto unless the drop in voltage causes instability. "enabled" means it will allow intel's specification of vdroop take place, which is designed to protect your cpu. I think the "disable" option has poor transient damping and allows voltage to spike too high for a very short amount of time, low enough that programs like HWinfo can't pick it up. But I did notice that if I set 1.3V adaptive, it would go up to 1.452 under AVX loads. That's crazy that it has the authority to add that much voltage without the user consent.
What sucks about this is its something I submitted tickets about and hasnt been addressed. Actually, technical support told me to set 1.4V and 'disable' as their recommendation for overclocking... which is absolutely nuts, voltages would have been over 1.5V if I did that and would have assuredly ruined my CPU over time, if not very rapidly.

Some additional information:
Post code C pops up sometimes. Sometimes also the "memory_error_led" light. I tried moving the RAM around it it seems to flip between post code C and FF. Still no problem booting with a different CPU. I'm thinking now that the IMC on the CPU is what died.

Recheck you EPS Connector on the Motherboard and on the Power Supply. Look for Pins that may have been push out of the connectors and that they are Locked in the Sockets.

As always that's the first thing I looked for. Tried different EPS plugs on the PSU. Its definitely the CPU itself. My system was actually running fine and shut off randomly. Changed the CPU and it works. Changed it back to the 8700k and it doesnt work.

Totally amazing !! Such a good cpu what a pity... my 9600k's vcore is set on auto, avx offset 3, vdroop auto, manual o/c (very gentle) x47 (one core) x44 (6 cores) and the cpu voltage even under heavy tasks never overcome 1,17v, so these are very safe and protective settings which logically will prevent me from having the same issue as you !!

what motherboard? I'm on micro with manual voltage at 1.224v and only 16mV fluctuation. auto voltage and vdroop is just too aggressive on EVGA boards to use adaptive voltages comfortably.

Z370 ftw, the full atx version. I'm not completely convinced that the Mobo didn't fry my CPU but support pretty much said it couldn't be the board. Even though they're fully aware of the adaptive/vdroop issues, they won't acknowledge and fix it.
Last EVGA motherboard I'm buying though, that's for sure.

Yeah, I didn't have any issues at 4.7GHz. The adaptive voltage skyrockets at 5GHz and then seems to be multiplicative with vdroop compensation. I've posted about this before, but you could put adaptive 1.2V and see over 1.4V under load. That's insane and for some reason EVGA wont address it in z370. If you're not overclocking its fine, but the z370 is not an overclockers board. Its unfortunate because the actual components and design are fine. The BIOS are just really weak. ForTheWin

Correct. Vdroop has been given effective "load line calibration" levels in z390. This hasnt come to z370 and I think its going to stay that way.

On my Z390 Dark, I have voltage on Adaptive with a Vcore setting of 1.208. Under load while stressing my voltage generally runs 1.32-1.35 with occasional peaks to 1.36. This is at 5.1 GHz on all cores of my i9 9900k with +90% Vdroop.

I bought a 9900k and was curious to test the bios update on the z370 because my z390 comes in on Monday.
Cleared cmos, everything set auto. Started up and went to HWmonitor and saw it was cranking vcore to 1.42V at stock 4.7ghz all core. Seriously wth.
Im so done with EVGA.

I guess they might help somebody. I just hope it didn't damage my brand new cpu with voltage I didn't see. It's ridiculous that voltage is still all over the place.

No, support said it was likely not the board. I also don't want to pay to ship it just to have the same issue on the RMA. They suggested to reflash the bios too but that didn't do anything. I think they're just assuming it's user error, which isn't the case. If I put static voltage there's no reason why it should go 0.2v above that. I've checked this with a multimeter, so it's not software reporting error either.
I think they design the boards to do things that "enhance stability", without user input, so they appear to be better at overclocking than they are. But really it's just doing things you didn't ask for and at times can do things very wrong because of it.
I'll report back one last time when I get the gigabyte z390 board. But for reference I didn't have any of these voltage issues on Asus z370, or msi z370. They both overclocked my dead 8700k to 5ghz right at the voltage I set.

Threating the Bios of an EVGA Motherboard like an ASUS or MSI Bios is the same as Treating a MSI or ASUS Bios like a EVGA Motherboard, you can't do it. With so may Threads being posted well it works this way on Gigabyte Motherboard it should work on my EVGA Motherboard the same way is where the problem lies.. You cannot use Most Settings From One to The Other of different Brands of Motherboards. Sometime you cannot even use the Same Settings on two of the Same Motherboards Even with the Same CPU.

bcavnaugh, setting a simple voltage should not do anything except apply exactly what is specified. Not 0.01v more outside of Intel spec. There is a reason this issue has caused EVGA to be compared to other manufacturers. It's because they're doing it wrong and the others aren't.
A lot of people seem to be willing to accept these kinds of issues. A simple Google search shows that EVGA had these same issues going back to x58 and they still exist.
So I say the only way to hold a manufacturer accountable is it point out their short comings and allow them to fix it. If that doesn't work all we can do is vote with our wallet. So I bought a gigabyte board and this z370 is my last EVGA product.

Lucky on my EVGA X79 all it did was power down after restart, I used the little Red Button and all was well. *Intel did replace the CPU. https://click.intel.com/tuningplan/  The Performance Tuning Protection Plan website is currently undergoing an extended upgrade. A new website will be coming soon. Please check back later. For questions, please send an email to

Went from EVGA to GIGABYTE? Hah! Sorry dude... you definitely went backwards with that one. GB is one of the worst out there right now.
Anyway, I doubt a little voltage increase would kill your CPU. It most likely just died. Every piece of silicon has a finite lifespan after all. I've had CPUs running at well above max rated volts for years... no issues. I've had one die shortly after installing it too. It's just the way the cookie crumbles.
Oh, FYI: ASUS X99 motherboards were occasionally setting 1.8v on the CPU all by itself. So it's not just EVGA with issues.

Tbh I never used a gigabyte board before, but I'm satisfied with the build quality. Got my 9900k up and running and absolutely no issues at all. I set 1.28V and 5GHz and turbo LLC, and it goes right to 1.284V. Stable on P95 for a while now. I'm pretty happy with it. Glad I bought it and don't have to deal with the EVGA bios anymore.

satchmo0016
I bought a 9900k and was curious to test the bios update on the z370 because my z390 comes in on Monday.
Cleared cmos, everything set auto. Started up and went to HWmonitor and saw it was cranking vcore to 1.42V at stock 4.7ghz all core. Seriously wth.
Im so done with EVGA.
Hello! Can you try disabling VDroop in BIOS to see what that does to your stock VCore voltage? -Jose C.

Vdroop was "enabled", because that is the stock setting. Disabling it would have made voltage even higher. I think the VID values are not right, because there's no way intel spec is over 1.4V for stock performance.
