I could run the test script up to:

Fine-tuning deep autoencoder by minimizing cross entropy error.
60 batches of 1000 cases each.

Then I got a load error. But I didn't get any memory problem.
The memory usage seemed to stablized around 1.6GB (total
memory usage, when looking in the task manager). I'm running
a dual P4-3.2GHz with 1GB RAM.

You might try to tune the virtual memory:
System properties -> Advanced tab -> Settings (in Performance area)
-> Advanced tab -> Virtual memory area
