G5 2.7??
Have you check the AMD chipset under UAD control panel ??
make sure you select it ..

I'm not using Logic, but Nuendo. There is a marked improvement in plugin handling and numbers with the sample rate reduced. I track everything in 24/96 (well, 32 bit floating point/96) then down sample to 24/48, which gives me nearly flawless implementation of a LOT of plugs. I'm running a first-gen Dual 2gHz with 6GB of RAM, and using the Motu 828MKII firewire device, in addition to running the TC PowerCore Firewire suite.

actually i have same problem but only sometimes. with only one uad plug-in it tells me logic system is overload. i tryed to change card space in my computer and as well change its memory settings.
i also receiving error message -6026 with precission limiter.
i also receiving error message -6026 with precission limiter.
I sometimes get an overload message, but more seriously is that I get audio dropouts when bouncing mixes with as few as 4-5 plugins active (typically LA2A's and 1176'es) and a UAD CPU usage of about 55%. I feel the useability for UAD-1 has gone down seriously since I got my new computer – a 2x1,8 G5 with Logic 7.1 – compared to my trusty old G3.
Freezing tracks resolves the problem, but since I really like to use my UAD plugs on the buses this doesn't always suffice. Plus it takes forever to freeze tracks with UAD plugs on, compared to native plugs (even rather heavy ones like Native Instruments Guitar Rig). This is really getting on my nerves as I run a commercial studio and I just can't afford to spend all this time freezing tracks, double checking my bounces for dropouts, and redoing bounces that did have dropouts. I have version 3.9 installed and I didn't notice any improvement over 3.8.
I've checked all settings and can't find anything that seems to be wrong. Any suggestions welcome.
Best,
Henrik

Is your process buffer set to Large? I changed mine to Medium at another user's suggestion and it made a HUGE difference.
Thanks for your suggestions
Hi,
Thanks to everyone for their suggestions and, in some cases, moral support, for this issue. I would like to say that, while I love my Mac, I'm very disappointed in the performance (or lack thereof) from my UAD plugins. This is by no means the fault of the great people at UAD so don't get me wrong. If anyone is to blame it's Apple for their rather totalitarian policies that frankly, don't make any sense any more. OK, there, I've ranted. But I, like so many others, aren't the least bit happy with this situation and I hope that it will be resolved soon. Someone suggested I get a Magma Chassis but I've read where that might not be as much of a help as one would expect. Anyway, does anyone know if checking or unchecking the Large Disk Buffer makes a difference? I'm going to try reducing the Process Buffer to Mid or Low and see if that makes a difference. Once again, great forum and thanks for the help.

I have found in many cases using Larger Disk Buffer gives a lower performance than one would expect. Also, with the disk speeds and cache sizes on drives these days, Larger Disk Buffer is rather unnecessary unless all your audio drives are <54000RPM firewire drives or maybe your only drive is your internal laptop drive.
The process buffer size is also going to make a big difference, especially in the case of the UAD-1 plugins since they are always running off of this buffer setting (an issue isolated to Logic unfortunately). In most systems, Large can create more strain than small or medium. This is most likely due to Large being a large buffer size (2048). This means for each UAD-1 plugin, round trip is 4096 samples; a substantial latency, especially if you have multiple plugins going. This means there are large gaps of time (while the buffers are filling) before the CPU gets some data to process, and when it finally does get some data, it's this gigantic chunk. So while in general you will want a higher buffer size to reduce CPU load, it can get to a point where it is too high. Overall Medium seems to works the best for most (which is 1024) and small (512) working better for some.

Something is not adding up. I'm using SX3 on a Dual 1.8Ghz G5 PCI-X and tho I have my UAD in a Magma I don't think that you should be getting overload messages on your system if everything is set properly. The UAD and PCI-X problem seems to be more about number of instances than it is about the UAD itself. So 4 plugs depending upon which ones, should work fine. My Audio Buffer is set at 512, which works best for my system.
1. What is the exact Audio I/O device you're using?
2. What is the exact Audio Buffer size and Sample rate?
3. Exactly which plug ins are you running in the UAD and what is the UAD Performance Meter showing?
You really have to be more specific about your system settings.

i was getting alot of audio dropout's when rendering a track , ive just put a bigger power supply in my PC and suddenly no dropouts anymoreVogel said:
are all your devices getting the full power they need ?

Well, My personal experience.
When you bouncing or rendering plugin with audio track..
Make sure you are useing small buffer..
I used to send buffer to 1024 and get lots of pops and click randomly.
then set buffer to 128 even 64..
the Problem was disappeared......
