Incompatibilité a7v8x avec deux barettes RAM DDR400

Teste chaque barrette mais une par une avec Memtest86.
Fais bien entendu toutes les passes de chaque série.
Ca va te prendre 2 h mais apres tu sauras ce qu'il en est de tes ram.

Bonjour, sur le site d'ASUS, il est clairement écrit qu'ils ne garantissent la stabilité qu'avec une seule barette DDR400 :

Question
From VIA's web site, KT400 chipset only supports up to DDR 333 memory. Why does ASUS claims A7V8X able to support up to DDR 400 memory?

Answer
When KT400 chipset was first released, VIA officially claimed that it could support DDR 400 overall. But ASUS as well as other major motherboard manufacturer found out there were limitations and bugs for KT400 to support DDR 400. Thus, VIA modified the Spec of KT400 to DDR 333 max only. According to our test result, our A7V8X still can support Single DDR 400 memory with specific module. Therefore we still claim it able to support DDR 400. However, we have included the qualified DDR 400 memory vendors list on our website and manual handbook: Samsung PC3200 512MB M368L6423DTM-CC4; Samsung PC3200 256MB M368L3223DTM-CC4; Kingston PC3200 512MB KVR400X64C25/512; Please note, we only guarantee the stability if you install Single qualified DDR 400 module, other DDR 400 DIMM manufactured by other vendors may not be suitable for this motherboard.
