You aren't wrong I think in case we both get corrected - but it's oh so reassuring that someone has flashed your card before you do
The following quote didn't sound the card was working properly after flashing:
If the poster actually believed it was such a success, why did he later dump the card and got a EVGA reference card instead?drifter7508 said:
You probably want to read this link before buying this card for flashing, especially pay attention to the following quote:
If I'm not mistaken, this card is not compatible with the reference design with 3 different BIOS states, and has a default power target of 250W-330W with 2 8-pin connectors. If you are still interested after considering all the potential risks, be sure to use the 4GB ROM from another thread.
I vaguely remember one or two people trying the GTX 680 Classified over in the 4GB thread, but this post was all I could dig up. I cannot find Durex's post-flash report of success or failure.
I only looked for a minute or two. You might want to do a more thorough search yourself, or better yet just PM him.

Thanks xcodesyn for your reply.
When I read the thread, it sounded like he (Drifter7508) had the problem with the ASUS GTX680-DC2O-2GD5, then purchased a new card and still had the problem. Then he flashed his PRAM and all was well with the world. So was it the computer or the card? I was hoping he would chime in on this
He got the reference card...
Got it today.
Still 10 sec delay before grey screen.
Still fans go crazy on cold start.
Will do some game tests now.
Then..
Still more issues..
On a seperate note:
Are all GTX 680's basically the same, even though they have different cooling and slighly modified clock speeds? The mac rom would just modify the cards clock speed to the eva mac card and give it the mac grey boot screen, yes?
Thanks in advance for your help!

I was trying to flash my EVGA 02G-P4-2680-RX GeForce GTX 680 2GB 256-Bit GDDR5 PCI Express 3.0 x16 HDCP Ready SLI Support Video Card, I put in the card, was fine in OS X, since I had the drivers already installed.
Then I booted through bootcamp over to Windows 8.1 Then everything went to heck. Anyway, at first I had a 640x480 screen resolution in Windows 8.1, then I rebooted and it all went BLACK. I can't boot into Windows 8.1.

I think I'm up to a dozen 680 flashes and not one with Win 8.1, all 7x64.
If no one helps here Rominator/MVC has no doubt done hundreds more than I, perhaps on 8.1 but posts mostly on netkas.

In the last few posts, the PCIe fan problem is being associated with a failed flash, which is just not true. The fan problem is not a reflection of what model cards are confirmed flashable or not.
There are many other posts about this, but to summarize, the fan issue has occurred with flashed cards, Mac Edition cards, and even official Apple OEM cards. There are confirmed flashable models that have had the fan problem for some people and not for others. All of these cards work otherwise, and someone determined that the problem is in the Mac Pro's SMC.
So drifter7508 having the crazy fan issue is NOT AT ALL an indicator of an unflashable model.

Thanks ActionableMango for your response!
It sounded like drifter7508 blamed the problem initially on the card, that’s why he replaced it. I wish he would have reinstalled it after he figured out it was not the card, but his computer. Other than drifter7508, I have not seen anyone else try to use this card (ASUS GTX680-DC2O-2GD5) on a MacPro.
Did he? In the thread I saw, it sounds like he solved the problem the usual way with openGl or fan control software.

It appears to me at this point that the reference card is the one in use. He changed the reference card from slot 2 to slot 1.
Thx for that one
Changed back my card to slot one.
Works much better. The open gl test fix the fans.
After that it all runs fine at original 800 rpm.
Will have a look at the Fan control app too
There is no mention of the ASUS GTX680-DC2O-2GD5 card after he initially swaps it out.
Ah, I see now.
I certainly understand your hesitation. Although I did not get a reference design card, it was a card that 3-4 other people had confirmed first.
ASUS GeForce GTX 680 DirectCU II OC
The other challenge I am looking into with this Asus card is the power requirements. It appears the reference design has a max power draw of 195W, which is well within the available power the Mac Pro can supply at 225W. The Asus card, listed on their website states a requirement of up to 300W.
A 3rd party evaluation from Silent PC Review showed a 23W idle and 203W under load for the ASUS GTX680-DC2O-2GD5.(http://www.silentpcreview.com/article1288-page5.html)
It seems like a little bit of a risk for me, but I am looking at getting a really good deal on this card.

I picked up the ASUS GTX680-DC2O-2GD5 card this weekend and wanted to double check a few things with those of you here who are more experienced with the 680 cards on a MacPro before I get started.
So, just to make sure I understand, when I flash this over clocked 680 with the Mac EFI, it will lower the clock speed and change the power requirements to match that of the Mac 680 card? Should I connect the two 6pin Molex connecters to a 8 pin adaptor and feed two 4 pin Molex from the optical bays to a 6pin Molex to suffice the 6 and 8 pin card requirements? Or, feed a 6 pin to the 8 pin Molex? I was a little more certain of my direction until I read this thread:

Asus gtx680-dc2o-2gd5
I installed the card today with two 6-pin molex connectors off the MacPro 3,1 motherboard. The first thing i noticed when powering the card up is that the 6 and 8 pin ports on the card seemed to be sensing with either a green or a red light based on proper power input. I first plugged them in, one into the 6-pin and one into the 8-pin on the card. The 6-pin displayed a green led, and the 8-pin displayed a red led. I could not get it to boot up properly. Next, I powered the two 6-pin connectors into the 8-pin connector on the card using an adaptor. Now the 6-pin displayed a red led, and the 8-pin displayed a green led. Still no boot up. Tried both slot 1 and 2. It appears this card won't function without the entire 300 watts available. Has anyone else had this experience with a non reference GTX 680 with 6+8 pin connectors?
When I plugged both of my video cards in, I confirmed that it was causing my computer to reboot multiple times... "White screen of death"
I guess I will have to wait to get additional power to see if this card will even work on a MacPo, let alone flash. Will order power adaptor for dual Sata to 6-pin molex and try again.

If I were in your position, being as I like to live dangerously, I'd just buy a 6 -> 8pin adapter.

I think this is the first 6+8-pin GTX680 I've heard of that won't work with the 6-pin wires. In fact, there was at least one 6+8-pin GTX680 that wouldn't work with an adapter, but worked once the two 6-pins were simply hooked up directly.
I looked up the clock rates on your Asus and they are lower than the FTW edition that many people are using. The FTW edition has a normal 195W TDP, so I don't understand why your card needs 300W.
Did you try PM'ing drifter7508? In your shoes, I would be curious to know how he powered his.
I did PM him, but no response yet. From reading a review on the card, it only uses ~203 watts under load, but it seems the card wants to see the full 300W. How much power it draws from each port is a mystery at this point. It could be that a 6-8pin adaptor will let the card function, but it may be that they designed in safeguards to keep us from under powering its ports?
Does it make sense that with it underpowered, the computer would reject it and not allow it to move pass the white screen...multiple reboots?
I don't know what is going on, but to speculate, the red/green LEDs seem like a clear sign that the card is designed to require 6+8 before it will work. A 6-to-8 adapter should work given that the power draw seems normal anyway.
But instead of spending more money that may or may not fix the problem for a card that may or may not flash, I'd just sell the ASUS and just buy a model that is known to work and flash. Some PC guy will be happy with the ASUS and you can get a card that's more suitable for a Mac Pro. Prices should be about a wash unless the ASUS is worth less for some reason.
I will probably end up selling this card, but I am so curious now, I want to see if this card will even boot up on my macpro.
I bought the ref card just to get rid of the 10 sec delay at startup. A pram reset would have solved that with the Asus card too (if I had know that then).
I powered the Asus card with a 6 to 8 pin adapter + 6 to 6 pin cord. No problems with flashing that card.
I have a 5.1 FW updated 2009 Mac Pro.
