carlos228 Posted February 24, 2008 Share Posted February 24, 2008 Hello, since 2 days I search a solution - maybe somebody can help me: Motion 3 generally works unstable on my System, I had some crashes, but not only motion but the whole system so I need to restart. I found a point where this can be reproduces: RAM preview. Every time I render here it eats up my RAM and then it crashes. Not alyways at exactly the same point. Even when the rendering worked, It crashes when I play the timeline. Looks like a Hardware problem, I know - but I changed the RAM completely, set dowm CPU clock and RAM speed to get more secure timings but the problems remain. Instability was on Leo 1.5.1, step by step I did system updates now: - Kalyway 1.5.2 combo - Vanilla Kernel - Pro Kit update 4.5 but nothing gets better .. :-( system works like a charm with other applications ! (o.k. I did no longer FCP tests yet, but it seems to be stable) setup: Gigabyte GA-P35-DS4 2 x NVIDEA Geforce NX7600GS silent / passive NVinject 1.0 (from kaly 1.5.1 DVD, works well on 4 screens) Leo 1.5.2 with kernel update ans all pro kit updates RAM: testet 4 x 1 GB G.SKILL (4.4.4.12 spec) and 2 x 2 GByte OCZ (4.4.4.15 spec) on specifies and save settings. has anybody a idea whats going wrong ? can motion be limited in RAM usage somehow ? (there is nothing in the preferences, but maybe there is another way) ? thanks in advance ! Link to comment Share on other sites More sharing options...
capitan008 Posted February 29, 2008 Share Posted February 29, 2008 4 gigs of ram is causing it to crash... i had similar problems... some applications would crash OSX during install, some when i run them. i have found a thread that many people have the same problem... After I removed one of 2 2gb ram chips all problems were gone. Haven't crashed since. Don't ask me why it happens. It just does Link to comment Share on other sites More sharing options...
carlos228 Posted February 29, 2008 Author Share Posted February 29, 2008 yes, I did now a mixed config with 1 + 2 = 3 Gigs & it works. In the installation area they talk about similar problems, it seems to be a bug togheter with the jmicron controller to get more than 3 Gigs. the G35-DS4 does a kind of pseudo dual channel ("flex mode") to enhance memory performance against the single channel mode.

carlos228 Posted March 2, 2008 Author Share Posted March 2, 2008 Problem found. Currently the only way to fix the 3 GByte RAM limit is to remove jmicronata.kext, deactivate the controller in BIOS and only use S-ATA Devices. The kext can't handle 64bit numbers.
