Just to confirm, that FSX prefers memory bandwith over the CPU clock.

I lovered the multiplier and increased the FSB clock (8x390 4,4,4,12) and I get smooth 30 FPS (moderate to high settings). It looks like RAM speed is important for FSX.

I'm still wondering why I can get past 390MHz FSB (780 RAM) with my PC800 CORSAIR TWIN2X2048-6400C4 which is declared for 800MHz at 4,4,4,12 latency (no matter what latencies, CPU/RAM voltages).

At 390MHz FSB it runs torture tests perfectly at 44C CPU (planty of room), but on 400MHz it can't even boot. Like there is some blockage (???)
