This is a memory corruption error. At some point one of your processes (Google Chrome Helper) requested to allocate memory, which the kernel tried to handle and failed a sanity check. If this is not reproducible it could be due to issues with memory instability or just bad luck. It is hard to know for sure what's happening based on the error alone. Cosmic rays, random memory errors or overclocking instability are possible. You are running 256G of memory at 3600mhz. This is a very ambitious overclock on such size with the Threadripper platform. Since your memory has no error-correction, I wouldn't be shocked if you get memory errors but you just get lucky enough they don't cause kernel or application panics. Linus Torvalds famously (in his usual 'colorful' style) commented on the lack of unbuffered ECC memory and how important he thinks it is to avoid random occasional crashes or even malicious attacks:

I would recommend you scale back your overclock to 3200mhz (you don't lose much of performance on this platform) which matches the officially stable IF of 1600mhz of Threadripper. I have a hard time running 256GB stable at 3600mhz even though my memory is rated (same brand).

Thanks for the suggestion. My memory is actually 3600MHz (if that's what you meant by rated?). But I would scale it back to 3200MHz.

You can run your memory more stably at 3200mhz CL16 and tight timings than 3600mhz CL18 and get better performance as the IF won't be overclocked beyond spec. Threadripper sweet spot is 3200mhz.

BS 11.2.1 released but nothing of interest to us, mainly for MacBook Pros.

I have Big Sur 11.2 working but when I try to update to 11.3 since I have access to developer releases it just hangs

I need to see if I am missing a kernel patch

is there a list I can use to compare against my config.plist in OC to see if one was missed or such?

Anto65 · February 10, 2021

hi you can check you plist with OCConfigCompare https://github.com/corpnewt/OCConfigCompare or here https://opencore.slowgeek.com/

Hi

you have to add new patch for Penryn in you kernel patches section if you are using an AMD cpu

you can find it in this thread

if you want, post your working config.plist you have in 11.2

thanks

Not related to his problem😉

I'm trying to install Mojave on my ryzentosh but installation process doesn't start....of course it dependes from missing kernel patches for Mojave. I search in github and there is a list of patches....but i'm as a newbie with AMD hacks so could someone help me to find the correct patches to use with Mojave?

I’ll be doing it at the weekend as there are some big changes as to how it works. It is now apparently a uefi app rather than just a program, eg bootstrap.efi has been removed and quite a few changes to the config file.

I’ll post a link to my efi when completed for anybody who wants it.

can we please get a link to your EFI folder with OC 0.6.6? 🙂

fabiosun · February 10, 2021

updated with the same set of kernel patches 😉

thenightflyer · February 10, 2021

Thanks 👍

@Arrakis

sorry I have lost your EFI in OP

when you have time can you post it again so I can insert in OP?

thank you

HERE you go. I haven't tried it with BS 11.3 Beta 1 yet but have added the additional patch so hopefully it should be OK. As usual, test it on a USB stick first before replacing your main one.

I have also updated my BIOS to F4n, the MMIO Whitelist hasn't changed at all. That is HERE if you want it (at present it is not available on the Gigabyte web site but is available if you request it from them).

Add this patch for 11.3 beta. Put maxkernel 20.3.0 to the old force penryn patch to mantain compatibility for the older kernels:

@fabiosun

and here is my EFI under OpenCore 0.6.6 / BigSur 11.2 so there is no patch for Big Sur 11.3 😀

Edited April 7, 2021 by fabiosun
EFI Removed (added latest in OP)

Foster · February 11, 2021

I applied the latest patches listed on opencore guide from github and 11.3 works

now want to optmize mmio etc

Hi @Foster

not useful to post EFI to optimize your MMIO

you have to post an Opencore debug log done following this helpful thread:

TRX40 Bare Metal - Vanilla Patches (Yes it works...but..Proxmox is better?) - Page 33 - General - MacOS86

now you are using some MMIOs in your config, but we can't say if they are for your motherboard or not from only an EFI posted

By the way, when you post an EFI you can delete APPLE folder before posting it..it is not useful at all to help 🙂

I'm very grateful (as always 🙂). Can you please share your BIOS settings too. I think I messed something up..

Ploddles · February 11, 2021

@JaidyI have messaged you.

MMIO entries done for my motherboard.

Only about 2-4 I had to actually change.

what apps kexts, etc used for fan, and power management?
