I posted this over in the F@H thread.
I have a GTX 470 in one rig and a GTX 465 in another. Each motherboard has two PCIe slots.
Since I can't afford to buy another of either of these cards I would like to put them together into one rig. The other rig would be free for a couple of GTX 260 cards.
I'd like some opinion on whether you think these cards will play nice with each other in the same rig.
I've got two GTX 260 cards folding on one rig but I haven't been able to get the GTX 400 rig running.
I think this is a BIOS/Motherboard problem but first the rig.
ASUS M4A89GTD PRO
AMD Athlon II X3 435 AM3 95W running as X4.
EVGA 012-P3-1470-AR GeForce GTX 470
EVGA 01G-P3-1465-AR GeForce GTX 465
Microsoft Windows 7 Home Premium
Has anyone used that motherboard with two video cards?
This motherboard has onboard video but I have it disabled. I have the GTX 470 in the primary slot and the GTX 465 in the other one.
The second card is not recognized in Device Manager.
I've tried various BIOS settings, uninstalled and installed the driver, used a dummy plug.
So far only the GTX 470 is recognized.
Note:
I just checked the Asus Download page and there's a BIOS fix for this...
Fix the issue that system may be unable to detect the VGA card in PCIEX16_1 slot When using two NVIDIA VGA cards.
I'm going to update the BIOS and see what happens!!!
Update 2:
I can't get the BIOS to flash!
I'm going to bed and start again in the morning.
No pie for me!!!
Fixed:
Well at least I got them folding.
When I tried to flash the BIOS the screen locked up. Before I went to bed I thought the video was the culprit but after sleeping on it I awoke with a feeling that it was the keyboard. I had a USB keyboard attached and didn't have any problems with it. I begin to wonder if the BIOS flash routine needed a PS/2 keyboard. When I used the PS/2 the flash was successful.
The new BIOS did allow the nvidia cards to be detected. After reinstalling the driver and configuring the folding client I now have a GTX 470 and GTX 465 working together. Running the 611 pt WU the GTX 470 has a 11998 PPD and the GTX 465 a 8122 PPD. Folding alone the GTX 465 had a 10334 PPD so I'm not sure what I'll do next.
