UAD Error 26 with Samplitude and RME


Hi All,

I just got my first UAD card and really like the plugins. I'm getting some errors though. Whenever I start playback an have at least one UAD plug active, I get an error saying that the cpu limit has been exceeded plugin unable to load . The error code is 26.

This error happens everytime I hit play. Also, sometimes when I deactivate a plugin it doesn't free up resources. I have to restart the program and sometimes that doesn't even fix it.

Also, occasionally my cpu usage will go through the roof when I enable one UAD plugin. Deactivating it fixes the problem

I'm running samplitude 8.2 and RME hdsp. And I'm using UAD 4.0

Any help would be appreciated.

Somethings not set up right. I have what you have and SAM works great with the UAD cards.

What is your ASIO buffer set to? Did you follow the setup directions in the UAD manual? Set it up like how it talks about setting up Logic. Not Nuendo, with the extra buffers.

ALSO, only use the VST UAD-1 plugs, NOT the DirectX.


Thanks for the reply. I'm using the VST versions. I have the asio set 0 which is the max. I installed version 4.0 software first. Then put in the hardware and automatically installed the drivers. That was it for the setup. Was there something that I missed?

I checked my irq's and UAD card has it's own spot.

I disabled hyperthreading because I read that my cause a conflict.

1st try UAD DSP(CPU) limit set to 95%.

2nd would help if you can provide more detailed information about your settings and setup...


I have my computer setup for audio. All the normal optimizations.

I'm using the RME HDSP with Samplitude 8.2.

latency set to 512.

I have one UAD card. Matrox graphics card. Intel p4 3ghz

I disabled hyperthreading. All the UAD settings are default. I didn't change anything.

Already set limit to 95%.

I changed my drivers to version 3.9 and I'm still getting the err 26 message, but cpu usage is ok. Disk usage starts off really though.

Let me know what information you need.

Download SAM 8.21 also.

Are you still having the problems?



I can't use 8.21 because elastic audio is extremely buggy in this update.

I'm still having problems. My computer cpu is overloading when the UAD card is fine. Sometimes the UAD card claims to be running more plugins than it actually has -
