Yep Dumped it by dual booting into windows! But that's great if there's no benefit from it then it works fine without 🙂

Thankyou that seems to have fixed the topology and interestingly identifies as a QuadCore i7-8700 which obviously doesn't exist. Intel power Gadget showed low Processor Freq which was mainly why I didn't use the Penryn Family flag as to not try and reduce performance but as you can see the benchmark is quite respectable for running 8/12 threads overall. Not overly important I don't think? but I am not able to boot with a rom loaded for my GPU is this necessary anymore but when I define the rom file in XML I can't even show the Post Screen for UEFI so ill keep looking into that. Has anyone noticed any significant differences by loading the ROM?

I feel Ive touched on this before but can't seem to find it anywhere in the forum did we ever sort out the multiple CPU's and displaying correct topology to Mac when not using Penryn CPU's Thanks if anyone is able to shed some light on this or see if its the same for everyone else <vcpu placement='static'>8</vcpu> <vcpus> <vcpu id='0' enabled='yes' hotpluggable='no' order='1'/> <vcpu id='1' enabled='yes' hotpluggable='yes' order='2'/> <vcpu id='2' enabled='yes' hotpluggable='yes' order='3'/> <vcpu id='3' enabled='yes' hotpluggable='yes' order='4'/> <vcpu id='4' enabled='yes' hotpluggable='yes' order='5'/> <vcpu id='5' enabled='yes' hotpluggable='yes' order='6'/> <vcpu id='6' enabled='yes' hotpluggable='yes' order='7'/> <vcpu id='7' enabled='yes' hotpluggable='yes' order='8'/> </vcpus> <iothreads>1</iothreads> <cputune> <vcpupin vcpu='0' cpuset='1'/> <vcpupin vcpu='1' cpuset='7'/> <vcpupin vcpu='2' cpuset='2'/> <vcpupin vcpu='3' cpuset='8'/> <vcpupin vcpu='4' cpuset='3'/> <vcpupin vcpu='5' cpuset='9'/> <vcpupin vcpu='6' cpuset='4'/> <vcpupin vcpu='7' cpuset='10'/> <iothreadpin iothread='1' cpuset='3,9'/> </cputune> <features> <acpi/> <apic/> </features> <cpu mode='host-passthrough' check='none'> <topology sockets='1' cores='8' threads='1'/> </cpu>

It would yes but if so idve thought it would then default and recreate the topology line anyway to sockets=4 or 2 depending on how many he is choosing to passthrough

My 8700 requires the topology patch and his will too as his XML shows him using cores and threads if he swaps just to using sockets <topology sockets='2’ cores='1’ threads='1'/> rather than <topology sockets='1' cores='2' threads='1'/> it will work for him

See earlier post regarding Kernel patch required to boot CPUs that aren’t Penryn it’s also mentioned in the first post if this thread section 1.2 Are you using clover or opencore this will also make a difference to how you patch it

Try with less cores mine works with 4 cores 2 threads. Leoyzen has done tests and there doesn't totally seem to be a performance benefit however I noticed sound differences with mine. id also Avoid using an odd number of cores as this wouldn't be found in an actual Mac Spaceinvaderone mentioned this quite a while back.

Just an experiment I was doing that day but I had to have my wifi card as built in 0x1 to make handoff and AppStore work properly Sent from my iPhone using Tapatalk

This is what I'm seeing now with 4 cores 2 threads. Anything higher won't boot for me. But im happy to leave it for now.

Okay well reducing the cores from 12 to 8 seems to have fixed audio and booting and im booted with topology with opencore. TSC Frequency is stable at 3,200,00 at boot for three reboots now too scared to touch the config to figure exactly what the problem was i also added this back into my XML which might have something to do with it <clock offset='utc'> <timer name='rtc' tickpolicy='catchup'/> <timer name='pit' tickpolicy='delay'/> <timer name='tsc' present='no'/>

Interesting thank you had to remove the \\ but UNRaid is showing the cores correctly but only with topology passed through without windows VM stuck and only shows 4 cores rather than 12 but the Host does still turbo boost and show all cores working when running benchmark in the guest

Yeah I have the Audio Passing through from My GPU fine without the need for kexts (ALC or HDA) only the function was needed but problem is with that Bluetooth and USB card audio I’m still trying to get clover to boot with no avail and no luck with topology still either ill keep experimenting i suppose

Still no luck With the extra flags sadly it showed 3,200,600 Hz for one boot rebooted without changing anything and back to 3,199,999 clover on Hackinabox doesn’t boot past clover flash so i will try and get a working clover config to test out tomorrow I suppose the real question as well is what is your audio like when playing videos music seems fine but videos I always seem to skip no matter the bus they are outputting

Im lost with what else to try My VM's seem to be unable to run at the same Clock Speed as the host In VM's Unraid Host: $lscpu | grep MHz CPU MHz: 4300.040 Ubuntu Guest Q35 3.1 Lscpu | grep MHz CPU MHz: 3190.244 MacOS Guest Q35 3.1 MacCPUID TSC Frequency 3,199,999 (Hz) Windows 10 Guest PC-i440fx 3.1 CPUID Core Speed 3192.00 MHz Host is Intel i7-8700 Unraid 6.7.0 All machines are using <cpu mode='host-passthrough' check='none'> with the exception of the extra -cpu flags for macOS virus capabilities shows host as Skylake-client-IBRS rather then CoffeeLake which is what happens if setting VM to mode=host-model The VM also acknowledged both changes in the CPU architecture but clock speeds stay the same Hopefully that's enough information for someone to help.

Thanks for figuring that one out! Still only showing 3,199,999Hz Does yours show the correct Frequency for your CPU? My QEMU arg now is -cpu host,migratable=no,+invtsc,kvm=on,+hypervisor with host-passthrough as the only cpu value up the top of my XML
