Topic: ff 400 low latency

Any value set below the default 256  samples settings at 44.1kHz produces pops and clicks. I'm running on a decently  fast i7 DAW under Windows 7 x64 using sonar 8.5. 256 samples produces an acceptable 5..8ms latency however I'd hoped to get a bit lower. Has anyone else been able to achieve lower latency with the FF400?

And yes, I have installed the latest driver and firmware.

Re: ff 400 low latency

Thanks, I'll get the latest tool and look at that tuning advice. Still, it's an i7/Gigabyte quadcore system with 4 fast drives. I'm doubting it's a h/w issue. It may have have something to do with Sonar 8.5 Producer X64 loading older 32-bit plugins. I also need to try starting S8.5p in safe mode w/o the plugs.

Re: ff 400 low latency

A fast CPU alone can not guarantee perfect audio performance. Drivers or configuration problems may interfere.

Re: ff 400 low latency

A friend pointed me here http://www.thesycon.de/eng/latency_check.shtml and I ran the tool. It said there were problems so I stopped h/w drivers one by one but there was no change so I began stopping runningapps and services. I thought it might be Avast a/v/ but it wasn't. When I stopped the Gigabyte GT6 OC config util however, the red bars in the latency mon tool  disappeared immediately. Ironic that a util to speed up the system was actually causing the problem. In any case, with GT6 stopped, I was able to drop the sample buffer to 48 which achieves 1.1ms latency according to Sonar. I played a project and it sounded fine so I'm pretty sure I found the only issue. This is the kind of performance I'd always heard RME stuff was capable of. Thanks for your help!
