MSI Afterburner CrossfireX problems

nooneisback · Apr 6, 2015

I've managed to crossfire my HD 7970 and my R9 280X (280X is a rebranded 7970) and every time I overclock my 280X it works perfectly. However, when I switch to the 7970, there are no clocks, or temperatures (they are all set to 0). I'm trying to increase the fan speed because when I play metro redux, the 7970 starts smelling like burned plastic.

I just noticed that my second card's fan isn't spinning. I don't know what's the problem since the computer recognizes it.

EDIT: When I turned crossfire off, it started spinning, but if I turn it on it doesn't.

Are they both locked into their pcie x16 slots?

Is the crossfire bridge on?

Are the power supply connectors plugged in?

What make and model power supply have you got?

Does it work OK if you don't OC any of the cards?

They are both locked in the PCI-e slots, the bridge is on, the connectors are plugged in, 1000W 80+ Gold LcPower LC1000 V2.3, they aren't overclocked, only the r9 280x has an updated black edition firmware.

I can't see your PSU in http://www.tomshardware.com/forum/id-2547993/psu-tier-list.html#xtor=EPR-8886

Can you?

What 12v, 5v and 3.3v readings are you getting in bios or from your mobo utility software?

In Crossfire they will have the same clock speeds - same as the slowest. So its futile just OCing one card.

It isn't on the list, I updated the firmware because it used ti be a single GPU build, but since I didn't need a second computer, I crossfired them. 11.88V, 5.1V, 3.384V (the VCore loadline is set to extreme because the CPU is overclocked to 4.5GHz.

Those voltages seem OK.

Remove the 280X and put the 7970 in the 1st pcie slot. Does it work OK?

nooneisback · Apr 6, 2015

Tried doing that already , also I'd rather not switch them since the 7970 has only one 70 mm fan. Yes, it does work well even if alone.

So - the 7970 works OK by itself and you can't smell burning plastic?

I gather the 7970 is a reference model card?

I rather think the burning plastic comes from the fact that when the 280x is working it releases heat directly on the non cooled 7970.

What motherboard? make and model

nooneisback · Apr 6, 2015

Gigabyte GA-990FXA-UD3 Revision 4.0

The spec says " if you are installing two PCI Express graphics cards, it is recommended that you install them in the PCIEX16_1 and PCIEX16_2 slots." - are they?

Now I understood what was the problem, yet I will be running single GPU for now since the second one interferes with my wifi card.
