No problems ,so what's wrong?

[Puddin'tate]

I am currently using an Epox EP-8KTA3PRO(via kt133a),Athalon 850 mhz CPU,512 MB ram,Luna II,and a Pulsar1 with Win Me .It's all running without a hitch and I did update to the 4 in one drivers.I tried the vlatency patch and it makes stuff "freeze up" so I've found it to be better left alone.I used to get "PCI overflow" problems with just the Luna 2 on rare occasions,but not anymore since adding the Pulsar 1.This may sound crazy,but how many master verbs and modules can I link together,before the maximum DSP,to create the PCI overflow?Isn't it supposed to be common with these chipsets?Does it mostly happen with many effects?
