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

post #1 of 26
Thread Starter 
I had briefly mentioned this problem while talking about the upcoming A10-6800K over in the thread---- http://www.overclock.net/t/1347709/amd-richland-a10-6800k-apu-thread/170

I had mentioned in my post # 176 that I have a AMD A10 5800K and I would like to add my discrete MSI HD 6950 2GB to run in compatibility mode...not crossfire of course, since that isn't an option with a 6950.

As I explained, I tried to add my 6950 to my A10 5800K but because its not a 6670 or 6570, the discrete GPU its giving me nothing but problems. I can't run the monitor cable out of the 6950, only the motherboard. Additionally, it wont let me into BIOS while the 6950 is physically installed.

(I watched a youtube video yesterday where the narrator said last summer. AMD was already aware of this BIOS problem and was "looking into it"
but I suppose that problem was never rectified.

With the card installed, I also loose my ASUS start-up splash screen, plus I also loose the splash screen that shows Windows 7 is starting up. Loosing those two features is no big deal to me..... but the lack of being able to access BIOS is a big deal. Who wants to pull the discrete card every time you want to access BIOS?

Additionally I had run 3D MARK before adding the 6950 and again after installing it but still running the monitor cable out of the motherboard. The numbers were near identical, so I wasn't really gaining anything.... even though 3D MARK recognized the presence of both GPU's.

So anyway....That is a quick summary of how the HD7660D and HD6950 are not working together for me.

Anyway... a few of the guys discussing the new A10-6800K were willing to help me sort this out but I didn't want to hijack the A10-6800K thread. I figured I'd start a new thread and see if you guys have a solution.

Papadope asked me
"Couldn't you install the card, plug your monitor into the video port on the motherboard. Enter the bios through the integrated gpu and motherboard output. Disable the integrated graphics in the bios, then reboot and plug the monitor cable directly into the 6950?"

I'm not sure if I can or not.
I have tried installing the card, and plugged the monitor into the video port on the motherboard. But as far as entering the bios through the integrated gpu and motherboard output. ----I'm not sure how I would go about that...having never tried or heard of that as an option. I only know that I can't enter it by traditional means on start up or by pressing the direct BIOS button, that is equipped on my ASUS F2A85-V PRO motherboard.

I was told that you should not try to disable the integrated graphics of the HD 7660D since its a iGPU and its supposed to remain functional, so that the csystem can swap back and forth between the iGPU and the discrete card, depending on the graphics demands/task at hand.

Even so, my motherboard does not offer any options to disable the on-board graphics through the BIOS, it only allows you to set the primary graphics to PCIE. I tried all that but just get a black screen. Of course I can disable the iGPU in DEVICE MANAGER(which I had tried but get just a black screen. I have to then pull the 6950 out and restart Windows...which repairs the problem, by resetting the IGPU again to ENABLED.

I'll keep an eye on this because I just picked up a HD 6950 1GB. I'm currently awaiting my new PSU from Newegg to install it, as it appears to require 2x6pin PCI-E connectors. I'm running an A10-5800K and MSI FM2-A75MA-E35 with bios version 2.0 released 2013-05-03.

If the monitor is plugged into the video output on your motherboard you are using the integrated graphics on the apu.
That is why you are not seeing a difference in the 3D Mark score.

On second read I think I have a better grasp of what is going on now.
I do not believe this is a chipset issue, it sounds like a hardware issue.
I think what is happening is that upon starting the computer the video is being sent to the 6950 (even if you do not see it) and that is why you are not seeing the splash screen or the bios. Once windows loads the video is switching to the integrated graphics on the motherboard output.

I would say you either have an issue with your motherboard or an issue with your card.
If you have tested the card on another computer and you know it is working I would give asus tech support a call and run this buy them.
They'll probably rma the board, this cannot be a normal issue.

OK, to follow up on the suggestion by Papadope

Ensure you have the latest BIOS
Remove the 6950

Remove power from the computer and remove the CMOS battery cell located right above the PCIE 16x slot.
Wait 2 minutes
Insert the battery cell again and power the system up.
You will get a warning about BIOS settings being lost or something like that.
Press F7
Select Exit
Select Load Optimized Defaults
Allow the computer to reboot
Enter the BIOS again
press F7
Set the clock, AHCI etc. as necessary, do not OC.
Select advanced at the top of the screen
Go down until you can select NB Configuration
Ensure you have the following:
IGFX Multi-Monitor disabled
Primary Video Device PCIE
Integrated Graphics AUTO
UMA Frame Buffer Size AUTO
HDMI/DVI Port Output AUTO
PCIex16_1 AUTO

When done:
Select Exit
Save Changes & Reset
Allow the computer to boot Windows and uninstall all AMD drivers and dual graphics stuff.
Shut down the computer
Remove power from the computer
Insert the 6950 card
Move the motherboard to the appropriate output on the 6950.
Start the computer and install AMD drivers again.

Sounds like a motherboard issue I'm running a gtx 650 with my 5800k with a msi-fm2-a55m-e33 and not one issue

One big drawback is that i have 2 other desktops but none have PCI'e slots for me to test out the HD6950. I bought the 6950 second hand off ebay so there is always a possibility that the card could have issues. I'll have to look this over tonight again.

Papadope....You had said: ---"I think what is happening is that upon starting the computer the video is being sent to the 6950 (even if you do not see it) and that is why you are not seeing the splash screen or the bios. Once windows loads the video is switching to the integrated graphics on the motherboard output."

What would happen if I had the initial graphics card (primary set back to iGPU instead of the PCIE/PCI?

Isn't that the way the iGPU is supposed to work when you have a Lucid Logix set up?

As far as your idea runs2far ..... I will try the little "adjustment" I just mentioned and then move on to your recommendation next. I wish I had a printer attached to the computer I'm using...it would be much easier than writing all that down to follow step by step.

Just one thing runs2far...you say that I should---- "Allow the computer to boot Windows and uninstall all AMD drivers and dual graphics stuff." Does this include all AMD drivers that were on my DVD support disk...included the Audio drivers etc...everything???

Man...I really hope that its not my motherboard having a hardware issue...like a bad PCIE slots or something ...I hate the idea of having to rip this apart and start all over again.

It's only the graphics related stuff you should uninstall, this includes Lucid and all that other stuff.

My fear is that you have set the system up for hybrid crossfire or similar, but the IGP in the Trinity CPU and the HD6950 can't cooperate.

Something has gone fubar in all the dual graphics settings and the system ends up only using the IGP.

My very long solution should ensure you only run of the HD6950 and the IGP stays off. When you don't run any intensive stuff, the HD6950 will lowers it's clocks etc. and save power that way.

This is in my opinion the best way to run your system, as the IGP can't contribute with anything serious compared to the HD6950, and the IGP will only hold the HD6950 back.

Further down the road, the setup may mature on the software side and you may end up being able to use the IGP for OpenCL while the HD6950 handles graphics.
Just remember that this is only a guess from my side.

Runs2far----I tried exactly as you suggested in POST #4 but unfortunately it didn't work.

I tried to do this last night but at that time was unsure about the removal of the AMD drivers. I have read that sometimes not everything uninstalls as its supposed to. So, when I removed the drivers, I just selected the option to remove all of them (including audio, etc...but no big deal)...thinking it would just wipe them all out and I could just put them back on using my ASUS support DVD.

Anyway, I then installed the 6950 as you said and booted up the computer with the monitor cable attached to the 6950. You had said to "Move the motherboard to the appropriate output on the 6950" but I figured you meant move the cable.

When I restarted the computer (presumably now) without any AMD drivers to include that of the 6950 all I got was a black screen and a message to check the cable connection. I waited about 3 minutes and then manually turned it off. I then swapped the cable back to the motherboard and restarted it. I still got the balck screen but no longer had the message to check the cable connection.

I'm concluding that there is no signal coming out of the 6950 but there is with the motherboard (iGPU) .....only with me having disabled the IGFX Multi-Monitor in BIOS, I will get no video to display.
I'm guessing if I were to again pull the 6950, then restart the computer, and enter BIOS, I could then switch IGFX Multi-Monitor back to enabled and get video restored out of the motherboard.


Is it likely my motherboard is having a hardware problem with its PCIe slots?

And yes...if we could figure out a way to just run all graphics via the 6950...that's fine by me.

It seems odd because when I had it all set up before with the 6950 installed, drivers installed for 6950, Lugid Logix turned ON, and AMD Catalyst installed----I would go under DEVICE MANAGER and both my HD 7660D and HD 6950 were both displayed and like the iGPU, the status of the 6950 was "This device is working properly."

If there was a PCIe slot problem, wouldn't I have been getting a different message? I really wish I had another computer with PCIe to test the GPU in for process of elimination. And Yes...if I have to just run the graphics via the 6950...that would be just fine.... if we can eventually figure it out.
I just realizeded that I forgot to check to Ensure you have the latest BIOS. I recall that the BIOS for my motherboard had were dated late December 2012....but I guess I need to check this...right?

Just a side note.... my PSU is a Raidmax 530W ATX12V / EPS12V Power Supply

OK, not giving up yet.

Removing everything related to the AMD driver, including audio is not "bad", the audio part is for HDMI audio out and does not affect anything beyond the IGP/GPU related stuff.

Yeah, in that case motherboard is the video cable for the monitor tongue.gif

The drivers are only necessary in windows, the BIOS/UEFI interface works on a standard set that does not require any drivers and you should always get a picture from the IGP/GPU.
If you disable the hybrid stuff in the BIOS and plug in a GPU, you should get an image on one of the GPU outputs.
In my case it's a little funny because I get an image on the HDMI port if I have a TV attached to the GPU, but my monitor is attached to the DVI output mad.gif

The latest version for your motherboard is BIOS 6002, and it is dated 2013/04/11, get it. Remember to load optimized defaults after updating.

I would advice you to update BIOS, load optimized defaults, plug in the 6950 GPU and start looking at getting a BIOS image from it, and then you move towards booting up windows and getting good performance there.

Yes we may be looking at a PCIE socket problem, but is you mention, it's hard to verify when you do not have a spare motherboard/GPU to test it.

Your current PSU is a POS unit, and you should change it when you have the money for it.

BTW:
If you are having trouble getting a video output, you can always do the following:
Remove power from the computer and remove the CMOS battery cell located right above the PCIE 16x slot.
Remove the 6950
Attach the video cable to one of the motherboard outputs
Insert the battery cell again and power the system up.

This will clear all values saved in the BIOS and revert it to default values, you will have to enter system date and such again, but you get a video output.
