Hi all

I recently had a gigabyte gtx 560 ti SOC edition and bought a new gtx 660 oc as the memory is three times that of the 560.

My problem is this; I hae a sabertooth 990fx rev 1 amd mainboard, which have 4 pci-e slots, I have a 750w Corsair performance psu and all the cabling, I trying to get my gtx 560ti to become a dedicated Physx card but my system will not recognise it. It boots up with 660 but will not let me make the 560 physx as it's not showing, not even in the control panel.

Ive moved the cards around, pairing in different slots, they both run by themselves but as soon as I try to get the gtx 560 showing with the gtx 660 on primary the PC thinks the cards not even there.

I've done the bios, flashed and even installed the newer rom, I've done everything I can think of besides formatting as I have windows 8.1 and hate re-installing all the origin and steam, and everything thats comes with that.

heres my set up

Windows 8.1
AMD 9590 BE clocked at 5.1Ghz
16GB corsair vengeance 1800
Cosair 750w pro performance /w thermaltake big boy water cooler
Gtx 660 OC 3gb pci-e
4 ocz agility 512GB
1 seagate 2tb
1 dvd/bluray writer
6 COUGAR VORTEX-Series 120mm fan High-Vortex
6 Arctic Cooling F8

I think I'm within my power consumption for the GPU cards, the gtx 560 ti uses 2 6pin and the gtx 660 uses 1 6 pin.

I'm at a loss, what do you guys think my problem is?

All the best

Not so much as power in watts.
but the amount of amps also the psu you have can provide across the 12v power rail/ or rails.

Work out what each card draws in amps. see what the total amp feed of the psu is for 12v, you will need to work out how much the rest of the components in the system use in amps of the 12v rail.

If the total exceeds the maximum amp rating of the 12v rail of the psu it is why the card is not showing in some cases. the system may also become unstable.

Another thought is if the board can switch between the pci-e gen 3 spec and a 2.0 spec card and run at the same time.

Or it cannot.

A 660 should be a gen 3 pcie card.
and a 560 should be a pci-e gen two.

You may have an option in the bios of the mobo to set the pci-e standard interface mode. If you do.

Then setting it to 2.0 should let both cards be seen and work by the system, as long as you have enough amps combined with wattage to drive each card.

To clarify, when you look in the Nvidia Control Panel, you don't see the extra card under the PhysX properties tab?

Did you do a clean driver install after installing both cards?

Hi, thx for the answers, from what i can work out im with the amps for each rail as I have a modular and each card has its own lead going to the psu and the load is ok.

17 Seconds: Yeah I uninstalled the drivers, did about 3 reboots inbewteen the re-install. I also re-installed Nvidia experience and that says that im up to date now, after 10 or so reboots the card still is not found, not in nvidia control panel nor in Windows control panel. I was expecting an exclamation mark beside the card in control panel at the very least, but for it to be completely ignored is a first for me.

So you need to figure out how to get the 560 seated and working in its PCIe slot.

Have you tried updating the motherboard chipset drivers? Not the BIOS, but the drivers.
