ASUS P5W DH - Problems + Fixes Thread

[Anaya]

Hello, My Spanish is bad, and my English is worst.

I have 4x1 Mushking XP2 5300 (666 / 3-3-3-10 / 2,1-2,2V)

With 340FSB they run at 4-4-4-10, 1,95V with no other Overvoltages.
With 350FSB they run at 4-4-4-10, 2,05V with no other Overvoltages.
With 375FSB they run at 4-4-4-10, 2,20V with MCH at 1,65 (1.03g) and CPU at 1,32V.
I cant make more than 375 with any other configuration unless I put SPD in AUTO.

The MB can´t post with 380FSB with 6-6-6-18 2,2V and Overvoltage in FSB/CPU/MCH

But with SPD in AUTO (5-6-6-18) with MCH at 1,65 and CPU at 1,32V, at 380FSB its fully stable (+6 hours blend Orthos) with only a 1,8V in memory. And if I use memset I can make 5-4-4-10 (I cant change CAS in Memset) at 1,8V at 760 (380FSB) with any Orthos error.

But if i put in manual, I need 2,05V at 700 (350FSB) with the same timmings.

I reprogramed the SPD (4-4-4-12 at 400FSB) of two sticks (the other two are off the computer) and reset CMOS, but the motherboard detect the same timmings.

I need to know How I can correct this problem, to have a good FSB with good timings and a razonable voltage.

Thanks.
