Video Card and Bios Settings
Video Card and Bios Settings
Not very certain about the correct configuration and BIOS settings. My setup includes:
Asus P5KC Motherboard
GeForce 8800 GT Video Card
Current BIOS settings:
Memory Remap Feature: Enabled
Initiate Graphics Adapter: PCI/PEG
PEG Port Control: Auto
PEG Port Force: x 1 (disabled)
Slots for two video cards, but only one is installed – one blue, one black. I’m using the black one and it’s working fine. Curious if this affected performance.
It really depends on the slot you choose. The blue slot operates at 16x, whereas the black one is only 4x. That's a significant variation in performance.
MadAdmiral has a point, moving the GPU to the blue slot is advisable unless you prefer a slower system. The Newegg specifications verify that the black slot supports up to 4x performance.
The motherboard manual also advises placing the GPU in the blue slot on page 2-24.
We suggest using a VGA card in the primary (blue) PCI Express slot, while other PCI Express devices should go into the universal PCI-E slot (black).
Refer to the motherboard owners manual for that too. Pages 4-23 & 4-24 cover those options.
I don't see any reason to change the values from the default values. You should change the "Initiate Graphics Adapter" option back to PEG/PCI since you're using a PCI-E graphics card. PEG stands for "PCI Express Graphics".
The manual also says to only enable the memory remap if you're using a 64-bit OS.
I changed it to the blue port, but nothing appeared. No video showed up with the standard configuration. The blue port only worked when I did this specific step.
The manual specifies the default settings for the graphics adapter. These include PEG/PCI as the initiation method, auto port peg control, and disabled force on port peg x1. It notes that the card functions properly in the blue slot with these configurations. You may also consider applying the "Optimized settings" in the BIOS if you've made adjustments without clear understanding of their purpose.
According to the manual, the standard settings are as follows:
Initiate Graphics Adapter: PEG/PCI
Port Peg Control: Auto
Port Peg Force x1: Disabled
The card should function properly in the blue slot with these configurations. You might also consider applying the "Optimized settings" in the BIOS, since it appears you've made adjustments without fully understanding their impact.
All of these steps still don't resolve the issue. Either the card doesn't run at full speed on that slot, or the slot itself isn't operating at full capacity. I have no idea why this happens with peg force x1 enabled.
I'm also puzzled as to why it only works when peg force is turned on.
I've attempted to reset the CMOS and tried the default settings, but nothing seems to function properly. The main blue slot only works with PEG Force x1, which leaves me confused about why. The P5KC should support 16x, and the Geforce 8800GT should also work there. It might be that the motherboard is faulty. I'm really stuck on this issue.
