MacVidCards has Mac EFI Titan and GTX780 finished – makes them into native OSX cards

David,
Ah so that lidded cpu thing changed in the 2012 5,1? did not know that. thought it was all mac pro…
cool and thanks for the wrench tip!

OK, spent weekend testing.

Sad to say, the Titan is probably NOT going to be an internal powered card as is.

I am going to try some things with other power connectors inside.

Fortunately I have a 5,1 MP that I killed #1 slot in from testing cards. So I can put Titan in slot 2 and if I blow up machine, so be it.

I have ordered 3 licenses for “Hardware Montior” as it should display current draw.

Let me just say this, my current “does it draw too much” test is Furmark from “GPUTest_GUI”

Even with a GTX570 it is possible to kill my 3,1 by running this at full screen.

The 780 has completed ever run, never a hiccup.

When I loaded it up with Titan, as soon as it got to place where it should start rendering the screen, the 4,1/5,1 clicked off. Never even started the process, just gave up at open.

Which is odd because the cards are similar with titan having more shader units and obviously TWICE the GDDR5 to power.

I spent hours playing Crysis 3 and Dishonored. I used 780 & Titan internally powered and neither one ever had any issues.

But the combination of it quitting Furmark and a thread I read here at CC make me believe that additional power is going to be only long term answer. There is a thread here where someone was running a Titan and it would periodically KILL the entire machine when pressed.

I am unable to make machines have issue with GTX780 so I am going to cautiously ship a couple of the first orders.

The Titans I will continue to list as “External Power Only” until I can find a safe, reliable way to power them.

The pity is that nobody has ever made a PCIE slot power extractor. There is 75 watts run to each PCIE slot. That happens to be the amount we need to make Titan stable.

When I return from Bay area trip, I am going to see about putting together a kit with 2 @ Titans or 780s along with the ODD Booster X5 power supply, along with needed bits and an install manual.

Not exactly Turn-Key, but it will offer a way to end up with a Mac Pro running more CUDA horsepower then can easily be imagined.

Sounds like a plan!

I have never considered Titan on internal power as if you push it you would kill the machine.

Ola had real problems when pushing it on render. Look the thread here:

I’m thinking of going to Titan route but wonder if it will be stable with lets say external 850W psu.

Would the Titan work in a Cubix?

They say even 3 Titans but i’m not sure if internally with external psu.

GTX780 makes great internal powered card.

I have purchased a couple licenses for “Hardware Monitor” Pro version.

I have found that GTX780 is within 10 watts of GTX570 during After Effects render.

It is 20 Watts BELOW GTX570 if running Furmark in OSX.

GTX780 with or without a GT640 EFI GUI is going to be new best setup for Resolve for those w/o expander.

Can you link to the single slot 640? Or is it on your ebay page?

It can run 3 digital displays at once.

Quite an improvement over GT120.

BTW, we are about to close for 1 week.

Friday the 30th will be out last day open until September 9th.

Quick question about macro 5,1 GUI options if also planning to use Cubix w/ Titans.

We currently have the 580 3gb standard evga PC Card in a macpro 5,1 and are planning to get a Cubix and put 3-4 Titans in there depending on what 10.9 osx can handle. We are wondering if that 580 is ok to leave in as the GUI or if it is advisable to for example replace with the 680 2gb or 4gb version – not flashed. How much of a difference would those make? Also if the Cubix is being used in our other davinci room will I miss the 3gb on the 580 if I replace with then 680 2gb card?

On 10.8.4 or 10.9 does having cards flashed for Mac effect performance or is it now just about boot screen?

[Andrew Smith]

Dave or anyone else here have some thoughts on this?

Flashed vs. non-flashed?

5803GB vs. 6802GB for GUI if planning to get Cubix and use 3-4 Titans?

Thanks
Andrew
