Hopefully I can get some answers here. I've been banging my head against a wall trying to further my OC and still be stable.
Let's start with my system (Should be in my sig, but might as well put it here as well). These settings ran a blended test of Prime95 version 29 build 8 for 15 hours without any errors.
CPU: I9 9900k @ 5024 MHz
MOBO: MSI MEG ACE
Ram: Corsair Dominator @3350 MHz
GPU: MSI GeForce GTX 970 (from prior build)
C: NVMe Samsung SSD 970 1 TB
D: 6TB VSD. (Very slow disk!)
Cooling: EKWB Custom Water Loop (560mm rad)
Case: Thermaltake Tower 900
MediaBay: Kingwin Media and Fan Controller
OS: Win10
PSU: Corsair Hx850i

CPU OC Settings:
So, I've tried pushing up the bus, tried the multiplier, neither worked. Any setting higher than what I currently have ends with a freeze or BSOD. I've increased the vCore to no avail (except for heating up the system, of course). I've played with increasing and lowering ram speeds, increasing and lowering ring speeds, and nothing. Changing the BCLK Amplitude has not affect (tried 800mV and 1100mV). I haven't played with the slew rate as it's been a long time since I've touched it, and I do not know what BCLK ORT is so I haven't adjusted it at all.
As for the crashes, I've worked through several of the errors causing BSODs but still have two that keep showing up: IRQL_NOT_LESS_OR_EQUAL (parameters showed it was a fault trying to write to an address in virtual memory (IRQL was DISPATCH_LEVEL but that's too specific for my knowledge). I've tested memory, but everything's okay (increased paging files as well). The second one is a NTOSKRNL.exe and the third one is a Hall.dll. All three of these make me think that I have to adjust RAM settings before I push higher, but any adjustment to RAM seems to either make it less stable or have no affect (although, I admit I haven't gone about this part in a logical fashion. Just make a couple adjustments out of desperation).
So, does anyone have any ideas? I find it really difficult believing I can be stable for 15 hours at 5025 and completely unstable with any setting above that no matter the vCore setting. Perhaps I'm wrong, but I find it more likely that I'm missing something or am ignorant of something since I've only overclocked three systems and don't spend a lot of time doing it.
