NVIDIA GeForce 7300 GT 256Mb Compatibility

[owen]

The above card does not appear in the Video Card database. We are experiencing some strange selection bugs (see attached image) on both of our 2 new MacPro workstations with these cards (see sig for full system info). The problem occurs with any non-black pens, is not limited to grouped elements and is not file specific. However it does not occur on the new machines with a New>Use Default Project Settings file. As it does not occur with existing files on the old G5's, so I am starting to think there is something in the office template which these new video cards do not like.

Has anyone had an problems with these cards?

I hope to be moving us over to 10 shortly and so a new template from scratch may solve the problem but only for those projects in the early stages.

Kernel Panic.
Sorry, I thought KP was a well know acronym (same as windows blue screen, for windows user).

Ah you mean this one (see attached)

No i have not had a single one of those on any of our Mactel machines yet. At my old office we had several G5's that would crash to that screen increasingly frequently. Eventually every one of them suffered a complete meltdown and needed to be sent off to Apple for repair. I don't know if they were nVidia, ATI or a mix but i'm pretty sure they turned out to be hard drive problems. We had 30 odd G5's of varying models though so 3 machines over a two year period isn't to bad imo.

I guess I've seen it so rarely (and not at all so far in my experience with Mactel machines) that the meaning didn't occur to me. I have (of course) seen plenty of the Blue Screen of Death, but I haven't seen it abbreviated. (BSD, BSoD?)

So I'm got a MacPro 2.66 / 3Gb ram / 7300GT, but... In a day I had just the second KP, both in Archicad's OpenGL window. I hope it's not the normality! I had another bad experience with nvidia graphic card on a PowerMac G5 1.6 mono, and the solution was to use the machine as new Server for our office.
Did you (or anybody other) have any KP with your MacPros?

I have heard of this problem with 3GB of RAM and the NVIDIA GeForce 7300. Taking out the 2 512 sticks apparently solved the panic problem but of course you are left with 2GB instead of 3GB.

Very strange... Is this a know problem related to MacPros? Where did you hear about this? Are you sure there was not more simply a buggy module in the 512 sticks?

The 512 sticks came with the computer and work fine. 2Gb was added and the problems started. The mac reseller performed tests and it was found that 3Gb of RAM caused the problem. It might be the combination of RAM sticks, I'm not sure.

If you go to the MacPro section of Apple discussions and search for kernel panic (and kernal panic) you will find a lot of people having memory related panic issues.

i'm currently testing a 2x 2.66GHz dual-core xeon mac pro. 5GB RAM and the 256MB NVIDIA GeForce 7300 GT graphics card. all the RAM came from the mac dealer out of the box.

i've had 3 kernel panics in a little over 24 hours. haven't had one since about 10.1 on an old Ti powerbook . . .

something's up . . .

At last I've returned my new MacPro and Crucial Memories with RMA...
I can't be sure the issue was memory related, they was too random and I had too less time (I can't cause one on purpose), but I didn't have any without the Crucial memory mounted. On the other side, the kernel panic logs made me think more at graphic card or drivers fault.
Now I'm working with my MacBook (1st week), that with it's GMA950 didn't give me any problem of this kind... I'll try again with next model of MacPro (MacBook is not exactly a workstation, even I prefer work with it then with the MacPro I owned)

i heard back from GS - it's not the memory - it's an apple issue with that graphics card combined with more than 2GB RAM. they sent me a couple of links which sort of describe the problem...

the solutions are to take out the extra-over RAM (or temporarily limit the amount of used RAM to 2GB using the terminal/command line), get a better graphics card, or wait for apple to fix it.

my thoughts are to wait for apple - 10.4.9 is rumoured to be released pretty soon. and that'll be the round-up of all outstanding major bugs in tiger before they move on to leopard . . .
