Black/Crashing R4BE Issues I've encountered over the years -
They exist, BUT, they are not always present. Certain software/BIOS settings trigger it on these boards. I have isolated the problems to a few things:
Nvidia drivers - Some of the 2019 releases caused random black screens. Happened on desktop with basically no load, happened while gaming, happened while idle. Driver update to most recent has completely fixed it.
Corsair Icue - Can, but doesn't always, cause random black screens. More of a slow-roll system crash, first the focused window would become non-responsive, then the system would slowly die, 1 thing after the next hanging until it was totally hung, no windows blue screen. Well documented on X79, Corsair can't be bothered, just like all the other Icue bugs.
Speedstep + C-State + Offset overclocking - When getting near the peak of the voltage/speed tipping point, for my chip, 4600 is tipping point after that I need to dump tons of voltage, if I let the PC idle and go into it's deepest non-sleep/non-hibernate power state, it won't wake up. Just dead, no errors reported in any logs. I believe this is a hard hang at 1200mhz when it occurs, voltage at that point is pretty low, as intended, but it doesn't come back. I have found no cure for this other than back off the overclock by 100mhz, or, disabling speedstep/c-states.
VRM limitations - through the years, experimenting with different LLC/VRM settings, I have found that there is a point, where the PC will simply insta-power off. Some sort of circuit protection, despite temperatures. I am under an EK full motherboard block, 11x120 radiator space, and the VRMs/CPU stay quite cool, even at extreme loads. With cpu at 70c during Prime small FFTs 26.6, 4.75ghz, 1.45vcore I can be stable if I UP the switching frequency of the CPU VRM and voltage to 10v. Extreme balance and 180% load with high llc. These settings stay alive. If I back off to what should be more gentle to the VRM, auto voltage/auto frequency or 450, and T.Probe vrm balance, it will hard reset during extreme loads. This reset only occurs when CPU package power = 180w +. \\\These are NOT safe settings for daily and have only ever been done in short bursts for epeen benchmark scores to trounce newer systems\\\
I have tested PSU load capacity, it's fine. With XOC bios on my 1080ti and 4.65ghz CPU @ 1.372vcore, my system can pull 1000+ watts from the wall running furmark and prime concurrently. It can stay like that indefinitely without issues (though, I like my 1080ti alive so I don't), so the AX1200i is not the issue with the above VRM limitations. It's something specifically either on the board, or in the CPU itself that's triggering a self-protect. (see pic for brief log I got a pic of doing this)
I have had all onboard devices on, all onboard devices off (sound/lan/wifi/usb/asmedia sata etc) and it doesn't matter for stability.
If you're having black screen issues for an apparently unknown reason, I encourage you to try different things. First clearly identify exactly what behavior triggers the crash, this can be tough in some cases that are inconsistent, but there IS a cause. Disable all PCIE slots except what's being used with dipswitches. Try different RAM configurations (# of sticks, speeds, xmp/non-xmp/manual settings), cpu full auto setup, cpu full manual setup, onboard devices on/off and if no hardware setup combination fixes it start sifting through your installed/running software and services.
The board is quite good as an overall package, but, it is an enthusiast board targeted to overclocking, as such don't expect to fire and forget, it was never intended/advertised as an "it just works" board.
At the end of the day, if you're needing absolute stability, limit speeds to 4.3/4.4 and vcore to 1.35 and uninstall all Corsair and ASUS software. At that config I've never had any stability issues whatsoever.
Of course I would be remiss if I left out the INEXCUSABLE 2400 memory strap bug that ASUS has known about since release and outright REFUSES to fix. Yes I am salty about this. Bastards, I'm glad certain people who left us high and dry aren't at Asus anymore, despite their significant internet reputation.
That said, upgraditis has gotten to me, jumping ship soon and will be listing board/cpu/ram/block as a package so some other soul can enjoy it soon.
I experience these black screens all the time. They started way before I had the iCue software and it has not gotten any worse since I installed it. I also at first thought it was an issue with nvidia drivers because I noticed the repeated error in the error logs, but I realized those errors only show up if I leave the black screens on for a few minutes. If I restart a few moments after the system freeze and subsequent black screens there is no nvidia driver error yet. That tells me it is not nvidia causing the issue either. I also did a test once and ran the board with no OC and a completely fresh install of Windows with no other software installed, yet the black screens still happened. I have come to the conclusion it is an issue with something on the board being bad, probably something to do with voltage regulation that eventually affects the PCIE slots that causes the nvidia driver errors to come up.
But I also have upgraditis and will be upgrading to a i9 9900k system in the next week or two. I'd love to go with the new Rampage board and those awesome new chips, but that brings my price tag to double than what I will have with the 9900k system, and the performance will not be any better. If it is better it won't be by that much at all. I was thinking about waiting for more socket 1200 systems and the chips prices to go down some but I need an upgrade now so 9900k it is.
