Then you will have to try >hash=24m, hashp=8m and cache=8m and see how that does... With Win98, I wouldn't suggest setting hash=48m, especially if you are running ANYTHING else. The OS just eats up way too much memory, and you'll get disk paging, which will slow you down a lot. With 64MB on my machine, I usually use hash=12m and hashp=4m. It's possible to set hash=24m...Sometimes it works ok and sometimes not. Either way, there will be VERY LITTLE difference in strength/speed/etc. Bob did an experiment with different hash sizes a while back to see the performance impact...Perhaps I can dig it up a little later and post it. IIRC, there was no significant difference anywhere between a small hash (4m, even?) and a very large one (384m). Jeremiah
