I think it's the 'kx' drivers that some have had success with (KVR is a site with lots of VST links).

That would be a starting point, although I've also heard of people having success using the SBLive in Win7 using the XP 64 bit drivers package from Creative. This driver only uses 2 gig of RAM, from what I can recall, but if it is an XP machine that upgraded the OS only, it may work.

If it was me I'd switch to a used m-audio 1010 or 1010lt (since the board likely supports PCI still).
Better convertor stability, driver stability and support, etc.
Just my thoughts.


I do not work here, but the benefits are still awesome
