Hello,

To me it seems like I'm not doing something correct with my desktop machine. Even the screensaver seems slow. Its about one frame every ~2 seconds or so. Even on my laptop which is an older Dell with an Intel Centrino the screensaver is fluid enough to look at least 25fps.

I'll try to give as much information as I can about my system and boinc:

Processor: AMD Phenom(tm) 9500 Quad-Core Processor (4 CPUs), ~2.2GHz Memory: 4096MB RAM Available OS Memory: 2944MB RAM Page File: 1853MB used, 4031MB available Windows Dir: C:\Windows DirectX Version: DirectX 11 --------------- Display Devices --------------- Card name: ATI Radeon HD 5450 Manufacturer: ATI Technologies Inc. Display Memory: 1720 MB Dedicated Memory: 504 MB Shared Memory: 1215 MB Output Type: HDMI Driver Version: 8.861.0.0 D3D9 Overlay: Not Supported DXVA-HD: Not Supported DDraw Status: Enabled D3D Status: Enabled AGP Status: Enabled Card name: NVIDIA nForce 750a SLI (Microsoft Corporation - WDDM v1.1) Display Memory: 1331 MB Dedicated Memory: 115 MB Shared Memory: 1215 MB Output Type: HDMI Card name: NVIDIA nForce 750a SLI (Microsoft Corporation - WDDM v1.1) Manufacturer: NVIDIA Chip type: nForce 750a SLI Display Memory: 1331 MB Dedicated Memory: 115 MB Shared Memory: 1215 MB Output Type: HD15 Driver Version: 8.15.11.8593


I have port 31416 open for the PC, I've tried uninstalling several times, but I just cant figure out why its so slow.

My only thought is the fact I use the ATI card to pipe 7.1 audio (and sometimes 1080p desktop) to a Sony STR-DH810 receiver, as well as running HDMI from my on-board nvidia 750a (8400GS GPU) to a 23" acer and VGA to another 21"

So far in my troubleshooting I haven't gone to lengths to disable displays since this would actually start to hinder my normal use of the computer; however I'm about to give that a shot to see if I can increase the crunching.

Any suggestions/comments are appreciated. Thanks guys.

I guess this is http://setiathome.berkeley.edu/show_host_detail.php?hostid=6563153.

I suspect you need to install the nVidia drivers rather than use Microsoft Corporation - WDDM v1.1 on the nForce 750a SLI. If you post the motherboard model that would help tell what the best drivers to use are. The generic drivers are available via http://www.nvidia.com/Download/Find.aspx and I expect http://www.nvidia.com/object/nforce-vista-win7-32bit-15.56-driver-all.html is what you should use.

Its an XFX branded nForce 750a Motherboard. Good call though, I cant believe I didnt notice that.

Do you think it'll be okay to run both driver sets at the same time?

Which both do you mean? The nVidia will replace the M$ one. If you mean nVidia at the same time as AMD/ATI then I gather it's possible, but have never done so. Good luck if you try it!

I think Claggy is the expert on that. I think it involved choosing the right order for the two cards to appear on the PCIe bus, followed by the correct order of installation of the two manufacturers' drivers.

IIRC, the drivers were 'NVidia first, ATI afterwards', but I can't remember the bus order.

I'm not sure the order on the PCIe Bus matters, i've always run the Nvidia card as the first device, and the ATI as the second, (i think arkayn and jamie might have run them in the other order)
The drivers should be installed Nvidia first, ATI second, otherwise the Nvidia drivers overwrite OpenCL.dll with their version, and then OpenCL computation on the ATI GPU doesn't always produce correct results,

I've switched mine around so the Nvidia card is in bus 0 now due to heat issues the other way. But I found it works either way.
With the OpenCl.dll, I've found it doesn't actually matter which way round you install the drivers as long as the OpenCl.dll in the C:\Windows\System32 folder is always from the ATI install (they use a slightly higher version).
So when upgrading the Nvidia drivers I copy the existing (ATI version) dll to a safe location, install the new drivers then paste the ATI OpenCl.dll file back into the System32 folder. Saves around half an hour of messing around with uninstalling and re-installing the ATI drivers, and still gives valid results

Currently I do not have a AMD card in my main machine, waiting for Thursday to roll around to put a HD7750 in there. I usually put them in whatever order comes to my hand first.
