Consiglio RAM

[Grenoli]

Salve a tutti,
visto che il mio computer è abbastanza vecchio e monta un solo GB di RAM vorrei fare un piccolo upgrade e portarlo almeno a 4. La mia scheda madre è una ASRock ALiveSATA2-GLAN e può montare questo tipo di memoria:
- Dual Channel DDRII
- 4 x DDRII DIMM slots
- Support DDRII800/667/533
- Max. capaciy: 8GB

In particolare mi servirebbero delucidazioni sulla marca migliore e dove posso trovarla a minor prezzo, inoltre se è possibile mantenere i due banchi RAM da 512 affiancandoli a quelli da 2 GB.

Grazie

Per quanto riguarda le ram, personalmente ho sempre montato Kingston...certo, si arriva anche a pagarle il doppio delle Corsair, ma un motivo ci sarà!

Per i canali con diversa capacità, ma frequenza e tensioni uguali, ho visto che il sistema li legge...poi come li usi sono affari suoi. Attento alla latenza...
