If you put a PC GTX680 card in a MP, and run 10.8.3, with the reference drivers from NVIDIA, you only get a Link Speed of 2.5 GT/s in OSX and Bootcamp. However, if you flash your card, at least if it is an EVGA card, you will then have Link Speed of 5.0 GT/s in both configurations.
At least that is how I have experienced it...
Hi cal6n,I beg to differ, fouel. These are screensots from a PNY GTX 680 (PNY VCGGTX680XPB), flashed with the EVGA ROM, but otherwise unaltered.
@ MacVidCards:
When you have the firmware worked out for other Nvidia 6-series cards, would you be willing to flash my MSI GTX 670 card? I got it prior to there being an official GTX 680 Mac Edition and would love to have the boot screen again. I'd be happy to compensate you for your time and efforts. Thanks in advance.
Thanks. I can do 670s very soon.
My sideline doing GPUs came about as a result of being an Art Director here in Hollywood. One day I went to edit my reel and got a warning that my GPU wasn't supported by FCP. Led me down a long road where I discovered that I could mod EFIs and make different cards work.
I have had a couple Art Director gigs recently and that has kept me from rolling out the newer cards. I also wanted to give EVGA time to make some $$$, they deserve it.
670 4GB rom is mostly done, going to start with 4GB 680 first.
I did have a meeting this morning for another shoot. "Product Porn" wherein we make stylized sexy ads for silly products. So I will be busy with that for next week but the 4GB cards are enroute.
Great work all!
So I went the pedestrian expensive way, as I needed to perform some testing, and bought the EVGA Mac edition. Works fine except all that extra dough and I still have the expansion slot fan rev to 1300RPM at differing times after boot ala PC only cards.
I was hoping for a more seamless experience
I have to run a stress test after initial boot to quite the Pro back down to regular 800RPM speed. Any hints on how to squash this annoyance? PRAM has been zapped SMC has been reset. Booting into Windows and then into OS X does seem to keep fans under control but any shut down and then a re-start will ramp the fans again. I have yet to find a definite pattern but it is a bother and makes me wonder why I didn't save the extra bucks and get a FTW model with higher clocks and the same issues.
i have the same issue too. with a mac pro 5,1 original (not flashed from 4,1)
i noticed even that my BOOSTA fans is around 850 rpm insted of 600 (when i use the 5770).
i have this issue with both of my 2 mac pro. so, i don't think it's a mac pro problem
E-mail EVGA since you have an actual EVGA Mac Edition card, hopefully EVGA gets enough complaints that they forward it to apple, and apple will release a firmware\software update to fix this!
It happens with the HD 7950, and GTX 680 official Mac Cards, and even some apple branded 5770's.
could someone explain me what i have to do please?
No one knows. We wait on Apple to throw some clues to vendors or a firmware patch. Until then use your stress app to ramp the fans back down on the rare occasions you do a full shut down and restart later. It no longer bugs me because I am always restarting or sleeping so the issue stays away.
The Post Open GL fan speeds look about right for 2010 Mac Pro idle. If there was a fix it would be posted.
thank you for the answer. so strange that someone has the issue and someone else doesn't.
i have a evga with this serial: 02g-p4-2687-kr
Who doesn't have the issue? Maybe they are in a loud room with no measuring software? There is probably a specific set of reasons why some and not others. Most likely based on firmware.
