ATI and NV GPUs in same host

[Ghost0210]

Hey all,

not sure how much luck your having with getting ATI cards with Cat versions >10-2 to work with nVidia drivers, but I decided to have a play today and somehow have managed to get Boinc to accept both Cat version 10-6 and nVidia drivers 257.21 and not crash out on start up 
The only way I could do it was to keep Boinc runnnig whilst I was installing 10-6 over the top of 10-4.
Then when I restarted Boinc I get the below messages:

30/06/2010 20:05:10      NVIDIA GPU 0: GeForce GTX 260 (driver version unknown, CUDA version 3010, compute capability 1.3, 878MB, 560 GFLOPS peak)
30/06/2010 20:05:10      NVIDIA GPU 1: GeForce GT 240 (driver version unknown, CUDA version 3010, compute capability 1.2, 987MB, 257 GFLOPS peak)
30/06/2010 20:05:10      ATI GPU 0: ATI Radeon HD5x00 series (Redwood) (CAL version 1.4.696, 1024MB, 620 GFLOPS peak)

Might not work after a full reboot but we may be getting closer to a way to get these two cards to work together

But can you get any Brook+ or ATI OpenCL apps to run standalone? If not then it's pointless.

As soon as I rebooted the box I got a system crash.
Although it seems that its ATI that is having the issues and not nVidia so much
With my monitor plugged into the ATI card, about 30 seconds after login, got the blue and white vertical stripes and the rig froze
Rebooted, this time with the monitor plugged into the 260, about 1 minute after login the system froze - no issues with the screen just a complete system freeze
If you never reboot the machine its one way round it, as Boinc can atleast work with both driver versions installed. But as a workaround its definately not ideal

I am running a host (Windows 7) with a Radeon HD5770 graphics card, mostly for AP/S@H. So far so good.

Now I've put a second graphics card, a NVIDIA GT240, into that host (for MB crunching).

My motherboard has two PCIe 2.0 slots (one with 16, the other only with 4 lanes).

As long as have the HD5770 in the first PCIe slot (with 16 lanes), and the GT240 in the other (with 4 lanes) all works fine.

But for cooling purposes it would be better to swith the cards. Unfortunately this does not work.

When I put the HD5770 in the PCIe slot with 4 lanes, and the GT240 in the slot with 16 lanes, Catalyst driver reports "no ATI hardware found" (or something like).

This is strange, because in Windows device manager I can see both cards.

When I put only the HD5770 in one of the PCIe slots (doesn't matter which one), and remove the GT240, Catalyst correctly detects the card?!?!

Is there something like a primary and secondary PCIe slot?

What to do?

There is thread already devoted to such configs.
Maybe mods could merge this one to that thread ?

Frizz23,

Did you have a monitor plugged into both cards when you swapped the cards round?

Frizz23,

No. Only to one card at a time.
When I had the combination GT240 16 lanes, 5770 4 lanes, running, I tried it with the monitor plugged into the 5770 - and only got a blank screen. The GT240 worked.

I don't think two monitors would make a difference.

Again: GT240 4 lanes, 5770 16 lanes worked. Even with no monitor attached at all.

Is there something like a primary and secondary PCIe slot ... and the 5770 needs to be in the primary? Or be the only card in the system? ... or something like?

I'm sort of stuck here

Frizz23,

Plug a Monitor into the HD5770!!!!,

Boinc isn't always able to see extra cards without Monitors (or dummy plugs) being used, so why would Catalyst be any different?

My system is Windows 7, 9800GTX+ in 1st PCIe slot, HD5770 in 2nd PCIe slot,

the initial time i installed Catalst (9.12 i think) it didn't work, but did when i connected a monitor (and rebooted),

then all i needed to do was extend the Desktop onto the HD5770, then i removed the monitor and haven't fitted it since,

since then i've been up and down Catalyst drivers, (and had the 9800GTX+ removed and refiited a number of times) with no problem with the HD5770 being detected,

At least that's one thing nvidia fixed in their newest driver release, no longer needing dummy plugs and monitors.

[Gizbar]

Even though it's not quite the same, as I had a GTX260 and an 8800GTX in the same host, I never needed a dummy plug or a second monitor even with driver version 191.07, on Windows 7-64HP. All I did was install the card, and reboot the system. When it got into Windows, I configured the card to run my Physx stuff for games in the driver, and it happily started 2 Cuda WU's.

Luckily, the friend who gave me his old system to cannibalise doesn't know that his prized gaming card of the time has been relegated to being a Physx/Cuda card!  He did buy an Asus Mars for his latest system though!

Giz.

P.S. I've now updated to 257.21, and to be honest, not noticed a great deal of difference...

Although is not the same I can not get working together two ATIs one 4250 in MOBO and one HD3850,
at least I'm working with HD3850 that is much faster than the one in MOBO.

with this brand new computer I've tried NVidia GT9800 & ATI HD 3850 and impossible to made it run together.

Did you try Catalyst 10.2?

Claggy

can't remember, but latest for win 7 x64 (both NVidia Drivers and ATI too)

now with this computer when I insert the NVidia GPU and properly installed latest
NVidia drivers, BOINC just doesn't want to start.

I had trouble the last time i refitted the 9800GTX+, already had Catalyst 10.6 installed, was just getting BSOD's, so had to remove 9800GTX+, uninstall Catalyst 10.6, refit 9800GTX+,
install Nvidia drivers (Nvidia GPU is in slot 1), reboot, then install Catalyst 10.6, (just to prove that Boinc 6.10.57 and offline Brook+ still crash in this config), then uninstalled Cat 10.6 and went back to Cat 10.2,

Boinc 6.10.58 is supposed to be a partial fix, i'm running it now, but haven't tried Cat 10.6 again yet, it'll just not use the GPU that it's having trouble detecting, easier to just use Cat 10.2,

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?
