Windows 7: ASUS P8Z77-V - Why do I not have a System Agent Config in the BIOS

ASUS P8Z77-V - Why do I not have a System Agent Config in the BIOS

Been a long time since I posted but I am hoping someone can help me with this weird one. I have an ASUS P8Z77-V running a Intel i7 3770K that has been running perfect since the fall of 2012.

Just today - I wanted to test the integrated graphics for an HDMI connection to a newly placed TV - but when I go into the BIOS - not only is there no item anywhere to enable the intergrated graphics chip - I cannot even see a System Agent Config menu - and there should be one?

WHat is happening. I am running UEFI BIOS V2104 (2013/09/16) which is the latest for this board - but why I am missing an entire key menu?

Pulling my hair out here - if anyone has any ideas - please let me know.

Cheers,

VP

That computer appears to be different from in your System Specs. I don't think the BIOS will have the settings you mentioned, have to do it in the Operating System. As far as no entry for the built-in graphics, I've found most computers don't have a way to Disable the adapter in the BIOS, tend to automatically disable when a Add-in card is used. The apparent reasoning is that if the card is removed how would the computer then be usable if one can't see/read the screen. There are times when the built-in adapter is bad and an Add-in card is necessary.

Updated my specs

You may be onto something with the graphics. I will pop my card out and see what happens.

Vocalpoint, I have an Asus Z77 board and in Asus Tweaker you should have a VCCSA which is the System Voltage to the System Agent, which should be left at defaults unless you are trying to overclock the on board GPU. Also under the advanced menu there is a section named System Agent. However, Berton is correct, most boards when BIOS detects a PCIe X16 GPU it automatically disables the on board graphics. The only exception I know of is if you have enabled Lucid Logix in Bios and installed the drivers in the OS. That allows the on board graphics to assist the dedicated GPU in rendering or editing video and such things.

Oh it gets better! As soon as I popped my Quadro out - the entire menu returned. So this is much more than just losing the command to enable/disable the graphics. On my board - if there is a video card in the slot - I do not see System Agent Config - at all.

And that menu has a ton of stuff that does not apply to graphics at all. Does it make sense that the system would turn off that entire area - simply because I am using a video card?

Well, yes and no. I have an Asus Z77 board, although a different model than you. I have a graphics card installed and I have a System Agent in my Bios. But, if the presence of a GPU disables on board graphics, a System Agent would not be necessary anyway.

Just to close this one off - after ditching the video card - this board is rockin with the HD 4000 graphics. Actually seems a lot "faster" running off the integrated chip - but that may just be a placebo effect for now.

I still am perplexed as to why this board completely ditches the system agent menu - which has a ton of extra stuff pertaining to other key parts of the system - when a third party video card is installed. But - it's getting a little long in the tooth now anyway...

Thanks for the assistance!

Vocalpoint, On my Asus Z77 board, under System agent, there is only PCIe configuration and Northbridge configuration. Under Northbridge configuration, it allows you to change the lanes for the pcie slots. Now, unless I am mistaken, which I very well could be, you only have 28 lanes in your pcie slots. Your card has taken 16 of those. That leaves only 12 lanes left, most of which are shared. So, there is not very much you can do to change the lanes left, so pretty much useless to have it at all. Mine does have it. About all I could possibly do is shut off my USB 3.0 ports and my esata ports to give me 2 more lanes, in the bottom slot, which I would be crazy to do. So, your board does not have it, but mine does. But, we are both in the same situation. Neither one of us could do anything but lose if we were to change anything.

But, I am glad you have your PC running well and it is running the way you like it.

Not so much placebo. In your case the integrated Intel graphics is actually faster than your old Quadro (which is based on the old Nvidia 9400 GT, which wasn't that fast even when it was new),
