Xeon 2667 V2 Issues

[luser01]

Greetings Everyone!

Just switched processors a couple days ago because I needed more single core performance.

** My system was working without issues using Dual E5-2690 V2.

I have been banging my head against the wall on a boot issue.

The error is “32 threads but 33 registered from MADT” .

New Specs:

Asrock EP2C602-4L/D16

64GB ECC Ram

CPU Model: Intel® Xeon® CPU E5-2667 v2 @ 3.30GHz

CPU Codename: Ivy Bridge-E/EN/EP/EX

CPU Revision: 306E4h

Logical Processors: 32

Nvidia 1080TI

I have tried multiple things. Custom ssdt-1.aml, generated the cpupm, added, removed kexts, etc.

Looking for some ideas.

Thanks

MaLc0n,

Thank you for your response.

I dropped your Clover folder in and tried. Still getting the same error.

I have tried with 1 cpu, hyperthreadding disabled.

[ref]luser01[/ref], u replace full clover folder? delete old clover folder and add new

[luser01]

First I tried mixing my files with yours.

Then I deleted my clover folder and added yours new.

Same results on both.

MaLd0n,

Attached is my clover folder with the dump.

[ref]luser01[/ref], is about a APIC.aml, is a Multiple APIC Description Table (MADT)

try a apic fix in clover config.plist

[luser01]

Same results.

[MaLd0n]

[ref]luser01[/ref], u try drop APIC.aml?

[luser01]

Yes. same results. I have heard of others getting these CPUs working, but no one has ever shared the secret.

I have the same issue, kp tho I only have 4c/8t, panic is "Should have 8 Threads, but only found 9 for die....."

Back story...I have been using my Dell T5500 workstation (dual xeon x5675/64gb ddr3 triple channel/gtx680) for a while with no issues, but it's now 10 years old.

Recently I got a newer model, the T5610, it can take 2 x xeon E5-26xx V2 CPUs (Ivy bridge era) x79/c602 chipset, USB3.

I only have one cpu, the E4-2637 v2, 3.5GHz, 4core/8thread, Win10 runs fine.

So I tried a clean install with your clover x79 series but get the kp.

it seems to be counting 9 threads instead of 8 and you have 33 instead of 32, others have 17 instead of 16 so seems like a math issue, always one extra.

I plan to buy 2 xeons for a dual setup, not the E5-2690 V2, they cost $450 for 2.

Thanks for your help.

I did a fresh dsdt extract (f4 from clover), dissasenbled with refs.txt and opened dsdt.dsl in rehabmans latest maciASL, pasted in your code fix, compiled with no errors, saved as aml.

I copied over the file to the boot usb.

Booted but still get kp

I took a video as it flashes past too quick to read.

kp is "x86_validate_topology() 8 threads but 9 registered from MADI"/BuildRoot/...."

Here is my clean dsl extract from F4 in clover

Thanks again for your help.

Still counting the wrong number of threads

see pic attached.

Added in 7 minutes 29 seconds:

The chipset used in the Dell T5610 is c602, which is an upgraded version of the x79, the mac pro 6.1 from 2013 used the c602j chipset.

[ref]dougsta[/ref], u try apic fix in acpi tab in config.plist

[dougsta]

I used the clover files from the x79 series, i'll reformat the usb drive and try the options you suggest.

The macos version I used is yosemite as I thought it should give less issues.

Do you think the version of clover could be an issue?

I'm sure this must be fixable as the chipset is very close to mac pro 6.1

Will try tomorrow

Thanks again

[MaLd0n]

[ref]dougsta[/ref], no, is a common problem in x79 and other chipsets after sierra

[dougsta]

I did a search to find out if the Dell T5610 has had any successful installs, seems it has been done before, there is a write-up on insanelymac

https://www.insanelymac.com/forum/topic/331372-write-up-installing-os-x-1012-sierra-on-dell-t5610-dual-xeon-uefi/

Next I searched for installs using the e5-2637 v2 cpu, didn't find any but did find people are getting the same 8 threads should have 9 type issues so I think it's a cpu issue.

I planned to get a pair of e5-26xx v2 xeons anyway so will research known working builds for the e5-26xx vs series.

Once I get the install usb booting and mac os installed I might need some help with getting is running nice, eg renesas usb3.

I picked up a server on ebay with 2 x e5-2680 v2 cpus (including a 1u case, intel motherboard S2600GZ, 16gb ddr3 1tb and 500gb hd) for £210

I installed the 2 new cpus in the Dell T5610 and the good news is there is no instant kp

It was the e5-2637 v2 cpu causing the issue.

I've attached the clover f4 dump with the new cpus, does the new extract need any edits to get it running nicely?

Good night, then your machine is working? dougsta.

I have similar problem with my lenovo c30. dual xeon.
