Throttling problem

[ernestomoralese]

Hi,sorry to post here, insanelymac won't allow posting. If there is a better spot to post this please tell.

My ethernet connection is throttling and suddenly the connection drops.

It happened first with an Asus Prime X299 DELUXE when I started to build this Hackintosh. I tried different bios versions, different bios settings, different EFI folders, different versions of IntelMausi, IntelMausiEthernet and different OS versions from High Sierra to Mojave. The MOBO was returned to the seller and I got a brand new Asus Prime X299 DELUXE II. But the problem persisted.

I went back to my bookmarks and notes, and noticed some posts regarding LAN throttling with some IntelMausi drivers. I focused on that driver, it was difficult to install the new version because it needed to be compiled in Xcode10 not 11 because of the need to run Mojave. After correct installation the problem persisted.

Right now I am running a clean installation of OpenCore 0.6.0 (very stable) but with the Lan connection problem. IntelMausi driver loads correctly and the connection appears green in Network control panel.

My actual configuration is:

Asus Prime X299 DELUXE II Patched Bios Version
12-Core Intel Core i9 10920X 3.5GHz
64GB RAM at 3200 Mhz
Bios: 0802 patched for X-Skylake

The only things that did not changed is the processor, memory sticks and a used RX Nitro 580 4GB.
The MOBO, Open Core and OS installation are new.

I think the problem could be, wrong bios settings, bad GPU or bad processor.

Please If you have any thoughts, I am feeling desperate, I can’t check with another processor, maybe the GPU.
