video card: xfx 5770 HD-577A-ZNFC
mobo: ASUS M4A78T-E (790gx, sb50)
So I checked and my card is running in 8x mode. I have only one card, its in the blue slot. The slot is labeled pci ex 16x 1.
I don't care if 8x is not going to slow down the card I want it at 16x to know my system is all good(for when i get a bad boy card).
So I went to bios and played around. I found:
PCIE frequency set at 100 (i tried bumping this up to 110 and 115 did not help.)
Under chipset > rs780d config > pci express config I have:
Port #02 - #07
port #02 and #03 where the only ones that had link width higher than 4x.
under the a port # I have
Gen2 high speed mode
link aspm
link width
So I Changed the link width to 1x, 2x, 4x etc. Each time I changed it, it changed in gpuz and cpuz. When I changed it to 16x it stayed at 8x. I don't get it.
So I pulled out the mobo book half the options where not in the book, the ones that where in the book just listed settings not what they done.
I cant find nothing with google. can anyone help
edit: Not a contact issue. I removed the card cleaned the slot and the card. put back in the card. No change.
edit 2: updated bios to newest still no go. stuck at 8x.
Thanks
