Do you have 4GB RAM? Are you crashing?

[Anders Haavie]

I have a quadcore with 4gig (2x2gig) and it crashes ALOT during rendering (heavy rendering with magicbullet, grain, vignette..etc..) . It pages insanely too, so I am buying another 4 gig to see if it works better. I thought that the the crashing was caused by memory leak in finalcut..

Thank goodness someone out there has the same problem.

I have a brand new spiffy top-of the-line Octo with 4x GB RAM and can usually only render long timelines in small chunks without crashing. It’s infuriating.

I too have done clean installs of System and FCS2 many times.

I will try the RAM reduction to 2 GB RAM.

But I am already somewhat disappointed that my 8 core doesn’t render as fast as I had hoped.

Is it possible that all this will clear up with Leopard?

I am so relieved that it’s not just me and my incompetence.

Please keep us all up to date on this problem and any fixes.

Best

Harry.

By the way, please do tell me if installing another 8 GB of RAm fixes this. You mention you are trying that in your post.

Please do post here with our results as I am thinking of doing that – or possibly just going into the retail footwear business.

Sorry – I meant another 4GB of RAM , bringing your total to 8GB.

I will keep you informed. This is definately a bug in fcp 6.01 and I really hope this is fixed in the next update. Extremely irritating.

[Harry Bromley-davenport]

Thanks a lot Anders.

I’m going to try to borrow 4 gigs of RAM from my dealer for a week to see if that improves matters.

It’s been a nightmare. I have, in the last two weeks done 5 complete erase everything and installs. At least I know that ohers are suffering too.

And yes, please do keep this board informed about your progress.

As far as render times, are you using ProRes?

Also, you have seen this, right?

JeremyG,

Yes, I am using ProRes.

And thanks for the link to the Apple site.

My Apple vendor installed all four of my 1GBs on one tier.

I guess that could be contributing, huh?

But when I called Apple, they said it was ok all on one tier but the support guy DID say that some people experienced crashes using Blackmagic cards (me) and 4 GBs. He said that when they removed 2 GBs and slimmed down to using the remaining two GIGS their problem seemed to be solved.

In any case I’ll move them around today and report back.

Thanks for the reply

Many thanks for the tip. You think this is a ProRes vs RAM problem, it seems to me.

I am using imx and it is still crashing here, so I guess it doesn’t really matter what kind of codec you are using. I too have to do small renders.. save.. render..save.. etc. Apple must fix this as fast as possible. I wonder why my mac is paging so much with 4 gig ram. Will try to do some experiments today, and keep you guys informed.

I am just getting my feet wet with ProRes (slowly working FCP6 into the busy schedule). Honestly, ProRes rocks my world in rt performance. I can’t get it to quit, but when it comes to render times, it is slow. I guess something has to give. The thing is, I am able to do soooooo much more in rt than before, so rendering all the time is becoming less necessary. Hopefully this will be sped up in an update, but ProRes is such a crazy and new codec, I’m not really expecting it speed up soon, unfortunately. Maybe Leopard, maybe, my hopes aren’t up.

And as far as the Ram tiers, yes. Follow that guide and it should clear up the problems. When the MacPros first came out, it was a big issue, and so was a 2GB limit, but all 3rd party manufacturers have seem to overcome the 2GB limit as long as you are using the very latest drivers for FCP6. Like I said, I am running 16GB and have had no memorable crashes.
