It seems some standard combinations as recommended by the manual do not work
with coreboot while some non-standard combinations do, so one cannot really
refer to the ASUS manual for memory installation if using coreboot.
However, it seems memory is not the main issue here as I just tried using 4 x
8GB Micron DDR3-1600 ECC Unbuffered sticks for 32GB, and it did not make any
difference compared to 2 x 16GB Samsung DDR3-1600 ECC REG VLP sticks that I
previously used.
The issue I'm having is more likely USB-related and it seems the issue is with
libpayload. The function "dma_memalign" might be the culprit, as the error
message "Not enough memory creating EHCI periodic frame list" is to happen if
dma_memalign returned null.
Reference:
payloads/libpayload/drivers/usb/ehci.c (from line 809):
/* Initialize periodic frame list */
/* 1024 32-bit pointers, 4kb aligned */
u32 *const periodic_list = (u32 *)dma_memalign(4096, 1024 *
sizeof(u32));
if (!periodic_list)
fatal("Not enough memory creating EHCI periodic frame list.\n");
By the way, I'm using two Opteron 6386 SE CPUs. Not sure if 6300 family
requires something else other than microcode (which has been generated from
tree).
