Compatible Graphics Cards with iBoot-Megabeast Set-up?

[Partman]

Is there a list of cards that work with the iBoot-Megabeast set-up?

Working:
XFX 8800GTS with 512mb, dual dvi
EVGA 9400GT with 512mb, dual dvi

Not working:
Zotac 9500GT with 1GB onboard (1 vga, 1 dvi)
XFX 9400GT with 512mb (1 vga, 1 dvi)
EVGA 8400GT with 512mb, 1vga, 1 dvi

Is there anything consistent in what DOES work and what doesn't? I'm not sure why all 9400gt's for example, don't work.

Is there a command line switch for graphics cards similar to the cpu busratio switch?


thanks -- Partman

Love the MEGABEAST!

Welcome to the forum! Any 8xxx, 9xxx card should work- it's just a matter of how much power you want. Check out some profiles and signatures to see some cards that are working great.

Not all cards are created equally, and there are sometimes differences under hood even if they use the same graphics chip.

One thing I've noticed that's consistent: if the card has ONLY DVI ports it works. All the cards I tested with a DVI and a VGA port did NOT work, even if they were the same chipset (ie NV 9400 GT).

Just tested a PNY GT 9500 GT with 1024mb onboard (VCG951024GXEB) and it works just fine on the Megabeast system and sees it as a 9500 GT with 1024mb. Again, twin DVI ports.

Strange, my GV-N98TSL-1GI has DVI + VGA + HDMI and all ports work...

inx2mac, did you just use graphicsenabler=yes to get your 9800gt running?
I am expcting my order next week, and my build is pretty much similar to yours (p55m-ud4, gb 9800gt silent cell, i7 860, i am going with a Kingston ssdnow v+ v2 ssd and 8gb 1333 valueram though)

Yep. No more, no less...

Good Luck,

I found a GTX 285 relatively cheap and that works with GraphicsEnabler = yes, as I believe the GTS 250 does as well...

Okay, I'm not new to building machines, I've built over 500 of them, but I am new to building and experimenting with Macs, so excuse me if this question is too basic. I understand there are a few very useful command line switches for boot up. When I had an i3 cpu in my current system, I had to add busratio=22 for that particular cpu.

I'm noticing that a lot of you use the graphicsenabler=yes. I assume this is placed on the same command line?

My big question is -- is there a procedure to place these switches in a startup file so that they are entered automatically? If so, can someone point me to the correct doc?

Thanks a lot. ~partman

There's a file in /extra called com.apple.Boot.plist - you can add any boot flags there and it will use them automatically.
