Alle ram di cui sopra, posso aggiungere 2 banchi di questa?
RAM DDR2 Kingston Valueram KVR667D2N5/1G 667MHz 1GB CL5 € 13,20 (http://www.e-key.it/product_details.aspx?ID=16042)
Sono compatibili?

Altra cosa, overclockai la cpu e mossi dei parametri dell'fsb e ora mi ritrovo con tali valori in cpuz:
dram freq 333mhz
fsb:dram 1:1
CL 4.0 clocks

devo fare qualcosa di particolare per aggiungere i nuovi banchi?
