Low Latency ASIO operation under Windows 2000/XP on single CPU systems:
• To use ASIO at lowest latencies under Windows 2000/XP even when only having one CPU,
the system performance has to be optimized for background tasks. Go to Control
Panel/System/Advanced/Performance Options. Change the default 'Applications' to
'Background tasks'. The lowest usable latency will drop from 23 ms to around 3 ms. This is
no issue when using dual CPU systems.
18.2 Installation
More information on installation problems (which fortunately are very seldom, thanks to Plug
and Play), can be found in the Tech Info 'Installation problems'. It is located in the directory
\rmeaudio.web\techinfo on the RME Driver CD.
HDSP 9652 is found in the Device Manager (>Settings/Control Panel/System<), category
'Sound-, Video- and Gamecontroller'. A double click on ' HDSP 9652' starts the properties
dialog. Choosing 'Resources' shows Interrupt and Memory Range.
The newest information on hardware problems can always be found on our website www.rme-
audio.com, section FAQ, Hardware Alert: about incompatible hardware.
The dialog 'New hardware component found’ does not appear:
• Check whether the PCI interface is correctly inserted in the PCI slot.
The card and drivers have been installed correctly, but playback does not work:
• Check whether the Hammerfall DSP appears in the Device Manager. If the ' Hammerfall
DSP’ device has a yellow exclamation mark, then there is an address or interrupt conflict.
• Even if there is no yellow exclamation mark, it is worth checking the ‘Resources’ tab
anyway.
• Check whether the Hammerfall DSP has been selected as current ASIO device.
