Final Cut Pro running on Intel Macs

Thanks again, Walter!
One more question for you. You mentioned having troubles with the FXplug stuff. How did you remove this? I’m just curious if this is my problem and I do have a backup of my drive, so I feel comfortable in trying this.

Am I correct, you can only run 2GB of RAM on the Intel Pro? Why is that? I bought 4GB for mine, haven’t run it yet with FCP, but the RAM shows up in the Sys Info.

Not a 100% sure, but I think they’re referring to “an ATTO issue with their fibre channel card” as Walter mentioned above.

The 2GB RAM limit seems to be with any PCIe card that addresses a mass storage device. Both Sonnet and CalDigit have the same issue with SATA cards. If you run more than 2Gb of RAM, the sytem becomes very unstable and crashes a lot. I know CalDigit is still working on the issue, but so far, no joy. I would really like to be able to put more RAM in the machine, but for now it will have to get by on only 2GBs of RAM.

OK,
You guys had me worried. So, today I fired up FCP (FCP5.1.2 QT7.1.3, NO PCI Cards loaded, 5 GB RAM and Firewire drives) Well, it crashes when doing long exports and renders. (I tested for renders and exports because a year ago, I had a crashing issue on my old G5 DP2.7 and it was due to a single, bad ram chip. So, that’s the first place I looked) I then pulled the RAM back to 1GB and it renders and exports perfectly – no isses at all.So, it’s not a PCI card issue as stated above. It’s a Mac Pro issue. Any ideas what’s up????

Jeremy just posted this link, which seems like a contender…

The above doc is not related to the 2GB problem… and it’s not just a Mac Pro problem as my Quad G5 had a similar, but less severe problem with storage hooked up to PCIe cards. The machines crash during long renders and other times at random. The crashes are usually gray screen five language kernel panics that require complete reboots. The problem has been confirmed by CalDigit and Atto… and I would bet that when the Sonnet driver is released for the Mac Pro, it will also crash with over 2Gb RAM… unless they found a way to fix it. I had the Sonnet 4 port multiplier card in a Quad G5 and it was very crash prone. My guess is it has something to do with communication speed vs. bandwidth… but I’m not a computer engineer, so I really can’t say. I do know that the problem SEEMS to be presesnt for any kind of fast storage card in a PCIe slot in a Mac w/ more than 2GBs RAM.

I’m getting the 2GB+ crashes with NO cards installed.

So is the problem with FCP… with the Mac hardware… with OS X… someone really needs to address this problem. Has Apple said anything about it? Is anyone successfully using more than 2Gbs of RAM w/FCP 5.1? What about external fast mass storage (not firewire or USB)?
-
What makes it confusing is FCP will run with 5GB RAM, but when you do certain things, like a big render or export (I was exporting a 30 minute show using Export self-contained) for testing, it would crash. Otherwise, editing worked and appeared normal. Again, when I pulled the extra RAM out, I could do the long exports perfectly with no crashes at all.
Zak above states he’s running 5GB RAM on his Pro 3.0 machine. Zak can you confirm you can do a long export like mentioned about OK?
