AMD A10 5800K and HD 6950 compatibility problems -- causing no access to BIOS - Page 3

post #21 of 26
So, with dual graphics enabled


IGP selected:
  • Mobo output displays the BIOS and boot screen
  • 6950 output displays the desktop when booted, with mobo output displayed as a second monitor.


PEG selected:
  • 6950 output displays distorted BIOS and when booted, the desktop
  • mobo output displays as a second monitor via 6950


With dual graphics disabled:

PEG selected:
  • mobo output is blank when the 6950 is connected
  • 6950 display is blank until booted

You said "I have my bios set to dual-graphics and the IGP selected for the primary display. I have no issues seeing the BIOS via HDMI through the 6950, but the display is a bit distorted on a 47' TV. I've set the 6950 to the TV via HDMI1 and the 7660D to TV via HDMI2, there is an image on both inputs."

Are you running the Lucid Logix MVP program to have them both work?

Lucid Logix MVP is a Windows program/driver and should not have any effect on the BIOS screen outputs, only the BIOS and a few select programs should be able to control how the BIOS works.

I am starting to become a little confused, I have read this thread and answered you + I have read the thread you linked to on page 2 and really can't see what causes the issue.

When you plug in the HD6950, the motherboard should use the HD6950 and you should get a screen output from it.
There should not be any compatibility stuff with GPU models and processors as long as the GPU interface and socket matches, which is does as both are PCIE 16x.
You should be able to put any recent GPU into that motherboard and it should just work with a BIOS screen output from the GPU card.
Setting up multi GPU stuff and so forth in windows will not affect this and I cannot find anything on a FM2 with hd6950 issue, the only thing I find is forum post on various forums, all originating from you.
Example:

Yet I know reviewers have been able to run the A10-5800K with a HD6950:

Maybe you just have a faulty GPU/Motherboard/TV.

I agree.

As per my post, try enabling Dual Graphics and select PEG then use the 6950 output. It should just work...

Let me know biggrin.gif

Sooner or later I'll find it.... or maybe I will just run it again for good measure.

I am waiting smile.gif
I am extremely curious.

Your issue is related to the motherboard/vga BIOS in my opinion.

Well it seems to me you must connect the monitor to the 6950. You are asking your system to do something that's just not feasible. Compatibility mode is accomplished through the OS,not bios. Whatever is hard-wired is what's going to work in the bios.

Thread Starter 
I have made just a little bit of progress on this problem. Here is what I did so far.

After updating the motherboards BIOS to the latest version and also the chipset, I set everything in BIOS to the default settings, meaning the iGPU was again the default graphics device.

I then physically installed the 6950 and booted up the computer.... using the monitor cable coming from the motherboard itself. The system booted up and I started Windows 7...still no access to BIOS no ASUS splash screen, or Windows7 start up screen.

I then went into device manager and saw that both my iGPU HD7660D and 6950 were both showing up and "functioning properly". I thought I had removed my 6950 already...guess it didn't happen so I manually did it at this point. I right clicked on properties and removed the MSI specific drivers for the 6950. (This was based on the hunch that what I had read might makes sense...meaning both the drivers for the HD7660D and HD6950 need to be the very same..remember I mentioned that earlier?)

After I removed the 6950 drivers I restarted the computer. When I restarted it ....the ASUS splash screen appeared and I could get into BIOS and Windows start up screen finally appeared..so I thought...Ok...I'm finally onto something here.

Windows 7 started and almost right away, I got a message that indicated the AMD Catalyst program stopped responding. I then went back into my downloads and re-installed the latest AMD driver for the 6000 and 7000 series of AMD graphics cards. (version 12.4 I believe). This was right off the AMD web site. (Not from MSI's website..the maker of my graphics card)

After another restart all went well (monitor cable still attached to the motherboard). In device manager both the 7660D and 6950 have the exact same drivers now. I reinstalled LucidLogix MVP and set it to dual graphics mode, with all the games settings to the default d-Mode rather than i-Mode...so the discrete graphics should be getting utilized as needed)
Here is a link to LucidLogix for anyone who better wants to learn how it works (and where I got this info):

http://lucidlogix.com/technology-virtual-graphics.html
Right from the LucidLogix web site...

Virtu Virtualization Enables Flexible Configurations:
i-Mode
i-Mode provides near zero performance overhead on 3D games, when no 3D games is used, the integrated CPU/GPU special features and power saving options are enabled.

To use Lucid VIRTU in i-Mode, display must be connected to mainboard video output as shown below.

(See photo)
d-Mode
d-Mode is provided for demanding 3D gamers to achieve uncompromised 3D performance of the discrete GPU installed in the system. In this mode, Virtu software allows user to utilize the special features of the Integrated GPU, while the display is connected to discrete GPU.

As 3D graphics performance is merely the same in i-Mode and d-Mode it is strongly recommended to connect the display to the integrated GPU, allowing power saving.

To use Lucid Virtu in d-Mode, the display must be connected to graphics card installed in the system. See below.

(See photo)

Strange..because their statement of
"As 3D graphics performance is merely the same in i-Mode and d-Mode it is strongly recommended to connect the display to the integrated GPU, allowing power saving. To use Lucid Virtu in d-Mode, the display must be connected to graphics card installed in the system"

..Doesn't that seem to contradict itself? They act like you SHOULD only connect to the motherboard then turn around and tell you that you must connect to the discrete GPU for d-Mode.

Anyway...with the cable stil running from my motherboard to the monitor, I then ran my free version of 3DMARK again. The HD 6950 displayed as my GPU in the test and the A10 5800K showed up as the CPU> In the end, all 3 test results showed-- valid.

I then tried some actual gaming and played my favorite MMORPG ddo.com for about 3 hours. I could clearly tell that the graphics were improved, as I could set my options all up on very high settings and no problems at all.

Prior to some game time...I did try to set my BIOS so that the PCIe would be the primary card and tried it both with and without Dual Graphics set in BIOS...I ran a HDMI cable out of my monitor but always got a message to check the cable connection.

So I have solved a portion of this problem. I also makes me now wonder if the HDMI port on my monitor might be faulty, since I never had anything hooked up to it via HDMI cable before. (I only have 1 VGA and 1 HDMI port on my monitor)

I wonder if I could try one of those cheap adapters to change my DVI output on the 6950 to VGA into the monitor and see what happens.
