670GTX not working, MP 3.1 , 10.8.3

[MaxHarryson]

EDIT: i ment 10.8.2 !! Sorry for misleading title !
EDIT 2: Works all right in w7 but it doesn't seem to outperform my 6870 by that much, possible CPU bottleneck?


I recently bought a Asus 670 gtx DirectCU II (or some other irrelevant suffix), the version with 2 6pin (i think that there is one asus version that has 1 6+2)¨

I updated to 10.8.2 and plugged the card into slot 2 since it won't fit into slot 1. It gives me no boot screen, as expected. But when it the screen finally turns on its full white, no mouse cursor or anything.

When i plugged in my 8800 gt into slot 1, keeping the 670 in slot two so that it would be faster switching back (removed all power cables from it ofc) the computer started doing an infinite restart loop, restarting at some point after the spinny thing pops up underneath the apple during startup. I tried restarting it a few times, including starting it up in safe and from the ML disk, everything yielding the same result.

At the final restart attempt I removed the 670. Suddenly it works again. I installed the latest drivers from nVidia and put the 670 back in. Still, whitescreen.

I popped the 8800gt in and switched to windows in bootcamp, then placed the 670 back in. It seems to be working in windows fully (Im going to try some 3d games on it now) after installing drivers from the website.

Anyone know whats wrong ?
As a side note, i had a 6870 previously but it gave me a blackscreen for some reason, even after installing all the kexts (or what they are called, I'm not that good on Mac OsX unfortunately). Worked the first time in OsX tough and also worked perfectly when booted into windows.

MP 3.1, 2x2.8 xeon, 8800gt / 670, 4gb ram

Recap:

- Asus 670 gtx gives no boot screen and then full whitescreen, nothing happening for 20+ minutes

-10.8.2

-Updated drivers from website

-8800gt works when 670 is not plugged in, otherwise restart loop

-670 works under windows 7 64bit

This poster seemed to have a similar symptom also with an Asus card, but in a 5,1 MP. Later the problem was solved by reinstalling OS X 10.8 as stated in this one.

Does reinstalling mean that i lose all of my files unless i back them up ?

edit : Read something about some other guy who had a similar problem but reinstalled drivers and had it work. Also seems that my card actually goes into the first slot, will try to boot with it there

edit 2: tried reinstalling OSX from the CD, nothing changed. I did not do a clean wipe and then reinstall everything tough. Will try and uninstall all drivers i installed then try again

Anyone else have any possible fixes ? Will it possibly work better in 10.8.3 ? should get "downgrade" to lion ?

We all know that GTX 670 should work with 10.8.2 and you are hesitant to do a clean install, therefore here's an easier way for you: Find an external or USB drive with at least 16GB and do a clean install of 10.8.2 on it and then use it as a boot drive. If it works fine with the GTX 670, you know you have conflicting files in your original drive probably from the ones you installed earlier for the 6870. Since it works under Windows, it can't be defective. Good luck.

How come the card doesn´t fit in slot 1?

I've not heard of this except with 3rd party coolers which have mounting apparatus on the underside of the card.

Yeah, like a watercooled solution, with a big back-plate

Awesome. I´m not sure wether to choose GTX 670, or wait for 10.8.3 and the HD 7950....

rumors say that 7950 has better money/performance ratio. The 670 is being bottlenecked quite a bit by my computer. However, its gonna go into a gaming pc soon so its k

They will cost me the same, so it´s a matter of AMD or nVidia.

The GTX 670 is almost $100 over the Radeon 7950 in the US and it has better overall performance. The main advantage of the 7950 is in the OpenCL and GPGPU area. Unless you are into OpenCL, it's a no brainer to pick the GTX 670 especially when they have the same price and NVIDIA has a much better driver support for Mac OS X.

Well, maybe it´s better to wait for some test with the 7950 - and 10.8.3
