10.8.3 with GTX 670 on Dell T7500

[Gothic4684]

Yep there is a A16 BIOS

I put both cards into each x16 slots... 670 in first x16 and 610 in second x16

I have 610 is second x16 fully working but Mountain Lion still does not recognize the 670

Playing around with moving the cards around now... I REALLY want the 670 working!

It's crazy isn't it I mean why in the heck does the Nivida Keats only load when 2 cards are inserted its nuts.

I can take a screen shot of what I mean. If you boot -v with just one card watch right after waiting for dsmos it never Says any of the nvidia kexts have loaded. if you put 2 cards in it says they have loaded. I think there r 2 kexts it will load.

OK now even more weird!

In switching cards around I saw a sticker on the bottom of my Galaxy 670... it actually says "GeForce GTX 670 GC"... I bet that the "GC" is why no matter what I do Mountain Lion NEVER loads anything for that card

Now for more weird... in the T7500 BIOS under Video options, there is a single setting for when using 2 graphics cards... Option 2 is default and sets the lowest x16 slot as primary (motherboard is flipped around like the Mac Pro's are)... Option 1 makes the second "middle" x16 slot primary

Default setting option 2... NOTHING works... bloated ugly graphics.

Option 1 makes it all work BUT ONLY with the 610 in the middle slot... WTH? O__O

Now for more weird!

No matter what the 670 won't work... the T700 came with the NVS 295 Quadro. Its been sitting in my closet collecting dust because It has never worked in Mountain Lion as a stand alone card. So I pull the 670 out and stick in the NVS 295 (because there HAS to be 2 cards in it for the 610 to work) and guess what?

The 610 works paired with the NVS 295 AND Mountain Lion actually RECOGNIZES THE 295!!! I have a monitor running off it right now BUT... remove the 610 and OS X cant see it any more.. I am blown away

Time to dump these Dell T7500's (yes I have 2)

No way mine did that with a quadro fx 1800 and my GeForce 640 it seems to be something about the pci slots

There HAS to be some way to get this 670 GC working!
