4 Moduli RAM da 512 MB PC3200 tutte diverse in Dual Channel a 333 Mhz

[daikengorobot]

Ciao ragazzi,

premetto che il PC è perfetto e non presente mai blocchi o altro ma da quando ho messo altri 2 moduli di Ram da 512 Mb mi riconosce la velocità del dual channel a 333 Mhz.
I moduli sono v-data, a-data, elixir, s3+ tutti pc3200.
E' evidente che il Bios trova valori tutti diversi dei timing delle ram e negozia la massima velocità a 333 Mhz.
Posto la situazione del Pc wizard 2006

CPU-Z mi dice che la configurazione dei timing dell'intera ram è 2.5,4,4,7.
Qualche consiglio ? Conviene disattivare l' SPD e cercare di forzare i timing ?

Grazie mille e alla prox.

Si conviene impostare i timing manualmente.
Imposta DDD400 3 4 4 8 2T e vedi come si comporta.

Se sei stabile prova a spingerti oltre.
Imposta 2.5 4 4 8 e cosi' via..................

Ciao,

ho provato a mettere 3,4,4,8 ma niente...il PC non si avvia. La scheda madre poi resetta le impostazioni accorgendosi dei problemi RAM e le riporta in modalità AUTO.
A questo punto credo che ci sia poco da fare, il Bios è l'ultimo.
Potrei venderle e prender 2 banchi uguali da 1 Giga.

Qualche suggerimento ?

Grazie mille
