Issue #658 has been updated by Keith Hui.

Out of curiosity I downloaded the boardview for this board. This is a board 
released in a time as we transition from DDR2 to DDR3, so it has slots for 
BOTH. The slots, counting outwards from the CPU socket, are:

DDR3 channel A (SPD index 0x50)
DDR2 channel A (SPD index 0x51)
DDR3 channel B (SPD index 0x52)
DDR2 channel B (SPD index 0x53)

That means you only have one usable slot per channel. You can't use both DDR2 
and DDR3 together.

For full proper support one would need to implement both DDR2 and DDR3 memory 
init. Angel can tell you that this is not a small undertaking.

Bug #658: asus p5g41c-m-lx pcie discovery of realtek 10ec:8168
https://ticket.coreboot.org/issues/658#change-2388

* Author: Gabriel Turlea
* Status: New
* Priority: Normal
* Target version: none
* Start date: 2026-07-14
----------------------------------------
I have tried to port coreboot to asus-p5g41c-m-lx by using the existing 
pg541t-m-lx variant. Everything works great except I cannot get the onboard lan 
realtek 10ec:8168 to be detected by coreboot. The card shows up and works once 
linux boots. Adding some register values in the overridetree.cb seems to 
disable the card even in linux. Please let me know what supporting info I 
should provide. 

Thank you
