MSI Z390 Godlike + i9-9900k 5Ghz Overclock Unstable (New Overclocker)

[GGXGraphics]

Hey guys!

My system is stable at stock speeds, I've been rendering some 3D animations for 3 days+ with no crash or bsod. Memtest86 didn't report any errors on my RAM.

But I'm not sure what I am missing, or doing incorrectly, or just unlucky on the quality of some parts? I've tried the basic 9900k 5ghz overclocking tutorials by MSI over their website, Gigabyte's guide, Der8auer's guide, JJ's guide (Asus). Tried the similar tips on their guides like turning XMP on/off, tested LLC levels of 3-7, voltage of 1.29 - 1.35, AVX Offsets -2 to -4m. I usually don't fiddle with settings that I don't understand or they don't mention changing, but everytime, it's unstable.

 

I understand that there's no perfect insurance on stability once you overclock your parts, but even a slight oc of 4.8ghz on all cores crashes cinebench R15/R20, BSOD's halfway through.

Even if I lost the silicon lottery, I'm willing to run the 9900k with higher voltages for a stable 5Ghz because it's a real game changer to preview your 3D animations in real-time. I just plan on using this stable 5Ghz OC profile when I work heavily for a few hours.

I'm getting really confused now because I've search many other forums and questions, and I think that other people with the same specs doesn't have this kind of problem.

Should I give up trying to overclock?

Thank you for your time.

whats the unCore? perhaps try 1.4v? I never use AVX offset, I got my 8600k running fine 5ghz

• Are you sure you're hitting 4.7 on all cores on stock and not throttling?
• What are your temps?
• Did you de-lid?
• Memory settings are not changed when running stock vs overclocked?

I'd set LLC to 6, and voltage could go up to 1.4 or 1.45 even, if you're feeling frisky, though if your core temps are already in the 90s, then increasing voltage is going to make more heat. At that point maybe a de-lid is in order.

 

I'd also set mem to 2666MHz while overclocking, just to rule it out.

...so you're tweaking numbers and dont know what they actually do? Seems like you arent using any tactics when it comes to the adjustments.

MSI and Asrock's LLC are inverted from Asus and Gigabyte, and none of them tell you the mOhms values either.

Try Loadline Calibration Mode 2 and 1.35v.  Set Uncore at 4300 mhz and DISABLE AVX Offset.

 

Then test.  And do not use prime95 small FFT with AVX to test your stability, either.  You can use 29.8 build 3 with AVX disabled in the new stress test options (useful) as well as the usual Cinebench R20 (custom 3600 seconds), and Realbench 2.56.

i'd start with 1.3v 4.8 to see if that's stable, if it is, then go 1.35 4.9 1.4 5.0 etc.

if 1.3v 4.8 isn't stable then you kinda lost the silicon lottery and that chip likely won't hit 5.0 even at 1.4v, which is the absolute highest i'd run with a 115i.

All values are AVX all core oc.
