I'm having problems getting a 3rd GPU working / folding.
I have a MSI x58 Pro-E motherboard which has 3 PCI-E x16 Gen2 (2x16, 1x4) slots
Evga GTX 580 SC <--- Only card w/ Monitor connection. OCed and folding fine
Evga GTX 260 <---- Add 4 days ago. OCed and folding fine
MSI GTS 8800 <---- In the 1x4 slot. Just moved from another working system **Non-Working One**
Nvidia 285.79 Windows 7 64-bit drivers
1. Kept GTX 580 (In First slot x16) Removed GTX 260 (In Mid Slot) and Reseated GTS 8800 (In bottom 1x4 slot) Rebooted and didn't see the GTS 8800 cards. (No Good)
2. Kept GTX 580 (In First slot x16) and Moved MSI GTS 8800 (In Mid Slot x16) Rebooted a few times and EVGA Precision & FAH GPU Tracker could see and manage both cards. (Better)
3. Kept GTX 580 (In First slot x16) and kept GTS 8800 (In Mid Slot x16) and Add GTX 260 (In Bottom Slot x4) Rebooted, had to rearrange all the icons on my desktop and EVGA Precision & FAH GPU Tracker could see and manage all cards. (SCORE!)
- Had to rearrange all my desktop icons.
- EVGA Precision GPU # doesn't match the FAH GPU Tracker GPU # (It's not in the same sort) * Anyone know how to change the GPU # in either program?
- I presumably EVGA Precision due to several card changes lost all the OC profiles.
- GTX 260 is in a PCI-E (x4) slot ** Any thoughts to PPD impact on the slower slot?
- GTS 8800 is in the Mid slot (x16) and OC (620/1240/850) is running hot 86C with 100% fan. **Update cards is overheating, dropped back to stock speed and over night it hit 96C.
- With 3 GPUs I needed to jump up the auto Fan monitor profile up by 10% for the GTX 580 & 260 and running fixed to 100% on the GTS 8800.
- I'm thinking the MSI GTS 8800 will not run in the (MSI x58 Pro-E Bottom PCI-E 16 slot in x4 mode), but the GTX 260 will.
Any other theories?
