I swear this is a 1N 2N issue, I have been beating on this for 6 hrs now, new 0801 build, ram proven to 1800MHZ on the P5E3 Premium and it won't load Vista at 1333 on this P5Q3, asus support are blaming the ram...how the hell can they do that when I can boot on their X48 board at 1800MHZ with the same dimms???

1GB modules seem a lot better, specially Micron and Samsung based, but they always do better as 1N is little stresss to them and the chipset, the issues come with 128's and 16IC's, the load is just to much.

Im trying to get SPD looked into also, maybe there is something we missed or the board does not like...as i said 1600eb 4GB kit running 1800MHZ on the X48 proves the ram is ok but im for sure missing something on this P45.

Regards posting on the OCZ forum, there are rules on the support section. if you wish i can move it to performance tuning and anyone can post and add to threads. The rules were put in place to stop end users jumping on others users threads....you have to post your own thread in support to make sure your issue is dealt with.
