Just looking to start a topic for info related to this new MSI card.

It seems to be the ideal mix of high ram and able to be flashed since it's a 7970 rebadge correct?

Newegg Link: http://www.newegg.com/Product/Product.aspx?Item=N82E16814127786

This is probably a bit too quick on the draw bit figured it's worth inquiring about.

I have a Sapphire 7970 6GB and it does not run well in 10.9.2.

Specifically, OpenCl causes it to crash and take down the computer.

I haven't tried in 10.9.3 yet.

Would be interested to hear from anyone else trying 6 GB card

I have a MSI R9-280X (3GB), unflashed, in a 4,1 (5,1) tower, and it does NOT WORK in 10.9.2.

Interestingly enough, my unlashed HIS 6870, which was working since 10.8.x really stably, also did not work in 10.9.2.
Had to back off to 10.9.1, which was a PITA.

If anyone can get the MSI R9-280X rolling in 10.9.2, I'd be very grateful. I think it has something to do with the mini-display ports; I need two of them as I use two Apple displays. It has something to do with a reboot loop or something per other threads I've read.

I have written about this a few places.

Needs to be flashed to work with MDP in 10.9.2.

Try 10.9.3 BETA

Bought MSI 6GB today and it does not play well with the EFI. Gives the bootscreen but that's almost all of good news.
Board isn't a reference design, it only uses reference port layout.

OpenCL works in 10.9.4 only when unflashed. When flashed it crashes the whole system when I launch Luxmark. Full 6GB recognized when flashed and unflashed.

In 10.8.5 unflashed works too, OpenCL kinda works: OceanWave doesn't crash but waves do not appear during benchmark. Only 2GB recognized by ASP, GLView sees 4GB. Flashed doesn't even boot to the desktop – reboot when drivers are starting to load.

In Yosemite it freezes the OS as well when flashed. Unflashed works. Full 6GB recognized.

Going to see what I can do to the EFI to make the card work as it should.
Feel free to throw some suggestions (netkas and Rominator especially, but others are welcome as well).

Imagine 2 of them in cMP: D700s would bite the dust. Resolve would love them.
It's certainly worth the efforts, so I'm gonna do all I can to write a good EFI for them.

@blacksheep,

did you notice any screen flickering from the MSI 280x Gaming 6G?

This happens to me every 5 - 15 minutes. Especially when watching YouTube I can replicate it very easy. OS X 10.9.3 and 10.9.4 latest seed. Just tested with 10.10  DP2 and the same there as well.

I never noticed this with the 3G version - although I had once a XFX 7970 Ghz Edition that did the same thing and I wasn't able to fix it.

Also the latest Bios is difficult to under volt. The card would crash at any voltage other then the default no matter what the clocking was set to.

I was finally able to under volt the card to 0.956V / 925Mhz by just changing the #0 VDDC to 0956 and leaving everything else in place.

From searching around this seems to be a somewhat known issue with Rev 1.2 cards and VBE7.

6GB and AMD EFI = NU BUENA

Verified on 7970 6GB and R9 280X 6GB

Only works well when no EFI on.

So with shipping ROM (no EFI) on a hackintosh, this is working well? especially OpenCL and Multi-Monitor?

Thanks,

Yep. I'm back to tinkering with D700 efi, but it looks it will be a long way ahead me.

As far as I can tell the MSI R9 280x 6G created screen flickering (in my hackintosh) every few minutes - at the end I decided to return the cards and replace them with Gigabyte 280x 3G OC Rev2.0

I overclocked GPU and memory in mine and flickering almost does not occur.
Unflashed works very well in 10.9 as compute only card for Resolve.
I won't sell it, I think.
Only complaint I'd have would be cooling, poor one.
Card gets over 85C under maximum load without thermal throttling.
Luxmark sees all 6GB RAM and gives a bit under 2500 pts in sala.
