Low Latency Settings For Edirol UA-25

[basil]

I'm using a Edirol UA-25 Audio MIDI USB Interface, for recording vocals using Reaper. I would like to use the direct monitoring settings in Reaper so I can hear the vocals with some FX on.
The Computer I use is Win XP Hm, 1.8 GHZ, 1024MB Ram 1600MHZ system bus

I've installed ASIO4ALL but I don't understand how to adjust the settings for the lowest latency. Using the Edirol ASIO I can only get 17.9ms usable latency and this is just enough to through timing off.


Thanks in advance for any help of this subject.

Played around with the ASIO4ALL settings and the lowest usable latency I was able to get in Reaper was 11ms/11ms so the round trip is 22ms. I'm able to get 8.6ms/9.3ms using the Edirol so the round trip is 17.9ms. Don't know if there is something I'm missing but I was hoping for round trip latency of less than 10ms using the ASIO4ALL for monitoring vocal recording without the doubling/phase effect.....oh well.
