People using RME HDSP/Multiface - what's your PCI Latency?

[basehead617]

does anybody here use an RME hdsp card with a multiface or digiface? powerstrip shows my RME running with a pci latency of 248 - that seems high -- anybody else running lower with better success? i had some stability problems with my other (home) machine lowering the pci latency for the delta too low.. i guess if there's one thing you want hogging the bus though, it's the soundcard.. (unfortunately this might adversely affect timing/cause dropouts when using a UAD or powercore especially the poco through firewire)

I use a Multiface. I remember seeing this value when I tried Powerstrip - can't see a reason to change it though. :?: It works as it is! :wink:

I'm on a Mac so don't have the \"Powerstrip\" but i have run the Multiface at 6ms. When i'm mixing I tend to buff it up for stability. If you are using Logic it sets the latency at 1024 for the UAD and it doesn't change even if you manually do so.

I have even run it at 3ms but only for when i'm recording and the latency is audible.

thanks but im talking about PCI device latency, but buffer size

Oh

The RME HDSP cards use 248 for PCI latency, but it is not a problem because they also release the bus right after dropping of it's buffers.

The problem with (some) VGA cards at high PCI latency settings is that they do not release eventhough they have finished buffer-transfer.

Post a latency Q into the RME forum, and Matthias will most likely give a better answer than me, but the PCI latency of RME cards do not need to be altered.

I couldn't help but think back to my 'smoking' days.. I know a few folks that were rather like a video card with their 'buffer transfers' once they got a hold of the 'bus'.
