freeing up PCI express lanes disabling bios
Posted: Fri Mar 16, 2018 5:01 pm
I just recently purchased a ASUS p5k to replace both my msi 975x and gigabyte p35 dsr3
both died.
P5k works.
one issue i discovered is
the intel p35 has 16 lanes directly connected to the north bridge
the Intel I/O Controller Hub 9 supports 6 lanes
2 lanes are used, 1 lane for gigabyte ethernet port and 1 lane for jmicro sata raid/pata ports which i am not using
on newegg several owners said complained that when there is a second graphics card in the 16x slot, they get 4x speed and the pci 1x doesn't work. some said they have raid
i use the pci e 1x for a dlink 556 wireless n card, though in retrospect i guess i should have got a pci card. asus p5k has 3
i'd like to install a m2 adapter 4x and use clover efi to boot, possibly and continue to use my wireless n card on the 1x slot
if i disable via bios either or both gigabyte ethernet and/or sata raid/pata will i be able to free up pci lanes for the remaining 1x slot or it doesn't work that way
i would buy this m2 at microcenter vantec in the event i can't get clover bootloader to work
asus p5k p35 is sata 2 not sata 3
