ATI and NV GPUs in same host

[Claggy]

Frizz23,

Plug a Monitor into the HD5770!!!!,

OK. Plugging in a monitor helped Catalyst to recognize the HD5770 (hopefully they are as smart as NVIDIA and remove this "feature" in the upcoming ver. 10.7).

Problem now: BOINC manager won't connect! When I start BOINC manager it shows no projects (because it's not connected). When I swap my graphics cards (from PCIe slot1 <-> slot2) it DOES connect?!?! ... that's really strange to me.

Any ideas?

Catalyst 10.2, as i keep repeating in various forums, is the last version that works with a Nvidia GPU fitted, anything newer causes the Boinc client to crash, offline Brook+ apps to crash, offline OpenCL apps to crash and GPU-Z crashes too,

Boinc 6.10.58 is a partial fix, it'll disable the problem GPU, but even if it didn't disable the GPU, the apps crash anyway, so it's pointless trying to run Cat 10.3, 10.4, 10.5 or 10.6,

I am using Catalyst 10.6 and it works fine with NIVDIA and ATI - even with no monitor attached. As long as ATI is in slot1 and NVIDIA in slot 2.

It doesn't work the other way round ?!?!

I'm running the Nvidia in slot 1, and the ATI in slot 2, with Catalyst 10.2 no problem, but the ATI doesn't have OpenCL support with this version driver. 
and i don't think i have enough room to put the 9800GTX+ in slot 2.

I think i've got my HD5770 working with Cat 10.7 now (with 9800GTX+ still fitted, and latest Nvidia drivers still installed)

I've tried Boinc 6.10.58, it starts and doesn't get a SIGGEV violation anymore, and HD5770 is detected, 

Doing a benchrun with Hybrid r433 now, will install SDK_2.2 next and try again with Hybrid, then OpenCL,

Cool ... what did you change?

Rename aticfx32.dll to aticfx32_temp.dll and aticfx64.dll to aticfx64_temp.dll in System32 and SysWOW64 folders,

Today I had possibility to install Win7 x64 on host with dual PCIe slots.
Now it holds GSO9600 in first slot and HD4870 in another one.
But BOINC sees only first (NV) GPU.
What I already done:
1) attached monitor to both GPUs. I checked, both GPUs show desktop OK, Catalyst manager can be invoked (if ATI GPU connected to monitor too), that is, both GPUs work OK.
2) Installed latest drivers. 260.99 for NV and Cat 10.10 for ATi
3) added <use_all_gpus> option to cc_config. But this step is optional BOINC not only doesn;t use secondary GPU, it just doesn't see it (only GPU0 listed in message tab at startup).

BOINC 6.10.58 x64, running under user account (not service).

Any suggestions what it could be ? How to enable both GPUs for BOINC under Win7 x64, what I missed ?

Only way I can get Boinc to see and use both my NV and ATI cards is by having the ATI in slot 0 and the NV in slot 1
also had issues with PhysX being installed when I first built this config so haven't tried with that again?

Until next week I have only remote access to that host....
I hoped some software-only changes are possible...

Before you do anything, try an offline run with an ATI app, if app crashes, try the fix in my last post.

Host unreachable 
It became very unstable... BSODs of non-standart look.
Usually it complains about some driver, but doesn't list not driver nor any addresses in memory to look for. So I even don't know about what driver it complains. Maybe Win7 would give some more info about problem, but only on next week

Hi,
V8-Xeon( D5400XS ) 4 full x16 slots
at first I had have
slot 3 Sapphire HD3870
I had have installed CAT10.5 and ATI Developer environment and could compile Open CL
all was working fine with this installation.
~~~~~~~~~~~~~~~~~~~~~~~
then I bought GTX470
I set it into
slot 0 GTX470
then I installed latest driver, Cuda and developer env.
I could not running both developer environments parallel.
Although both cards are detected by BOINC and worked, the dev environment for NVIDIA fails.
So I deinstalled all ATI stuff to bring the dev env for NVIDIA running.
I bought a second GTX470, removed the 3870 from slot 3 and set the GTX470 into slot 2
So I have now:
slot 0 GTX470
slot 2 GTX470
CUDA and NVIDIA dev environment works.
~~~~~~~~~~~~~~
I could not find a solution to run both developer environments.
my 2 cents

Heinz, I running both SDKs just OK on host w/o NV GPU at all.
What part of SDK fails in you case? Profiler ? Or you can't build app ?
[Actually, I have both SDKs on my netbook too where no NV, no ATI - just intel's integrated video-chip.
And I can build both apps on this netbook in VS2008 too.

When you had the Monitors connected, did you Extend the Desktop onto the second display?
(i just used the VGA connection, Monitor now just shows up as Default VGA Monitor, even when no monitor connected)

Desktop was extended automatically.
Actually, I attached single monitor with 2 inputs (DVI & D-sub) to both GPUs. DVI to GSO9600 and D-sub with DVI2D-sub to HD4870.
When I switched monitor inputs I've seen either usual desktop with taskbar or just empty desktop (secondary) with background picture and mouse cursor only.
Display properties in OS showed 2 monitors attached. IMHO it means that desktop was extended, right?
