macmunky Posted January 17, 2012 Share Posted January 17, 2012 I have a flawless working D620 thanks to you guys. But I am using my D620 for mixing with Traktor and there seems to be a performance problem. I don't see the problem when using Windows 7 on this laptop or Leopard 10.5 on my MacBook Pro (Early 2006). It is a T7200 w/ 2GB Ram. I would like to install 10.5 on it, but not Things I have done: I have created a USB boot drive, and it works up until the Leopard installer screen. When the "galaxy" screen shows up, I get a spinning beachball. I have installed the modded BIOS. When I copy the "Extra" file to the USB boot drive I get a kernel panic. If I remove just the preboot.dmg from the Extra folder, kernel panic goes away. Am I going about this the right way? Would I see a huge performance boost going to 4gb ram, and upgrading the CPU to a T7600? Link to comment Share on other sites More sharing options...
Administrators Bronxteck Posted January 17, 2012 Administrators Share Posted January 17, 2012 well we have never tried edp with lion... so no clue 4 gigs really helps but if the processor works good in windows then in theory it should still work in osx just as well..

derFunkenstein Posted February 1, 2012 Share Posted February 1, 2012 I had a TON of problems in Pro Tools 8LE on my D620 where Windows XP was fine. They went away entirely when I chose to run my CPU at max (1992MHz) from the PStateMenu. I think it's overly-aggressive in down-clocking the CPU, making it choke. Then when I'm done in PT I go back to On Demand Performance and the CPU starts down-clocking again. You won't get more than approximately 3.25GB of usable RAM on the 945GM chipset, though. You need a D630 or other 965GM chipset to get everything out of 4GB. Upgrading the RAM even to 3GB should make a big difference, and my PT sessions are very comfortable that way.

I will most definitely upgrade the memory. I actually forgot that I had posted this, so in my troubleshooting travels; I did find there seems to be a bug in Traktor Pro 2 that hogs the CPU. It sits idle at 90% (CPU Usage). I went back and installed Traktor Pro 1, and the CPU is barely above 15%. Link to comment Share on other sites More sharing options...
