P5b- deluxe can't set manual memory timings

[wunderbaum]

Need help.
I have 2x1Gb Corsair 6400 CL5 memorys and the P5B Deluxe. ( Core2Duo 6400) My problems are that I can not set the timings manually.

In auto mode not overclocked it sets the memorys at 400Mhz and 5-5-5-18 timings thats fine.
When overclocking the timings are set at 5-6-6-18 at 375 Mhz (400 too) even though the SPD is 5-5-5-18. If I try to set them manually, even to the same 5-6-6-18, the PC wont boot.

? Motherboard or memorys. In fact it OC bad, I cant get above 3.2 Ghz.
I tried a RMA and they said they switch the sticks but...

(BIOS 7-11)

What kind of voltage are you giving the memory? You'll probably have to give it a little more. But you'll have to give us a little more info, what other settings have you changed.

Nothing wrong with the mobo, but the memory isn't that great. CL5... *shivers*

Don't expect to go much over 400fsb without dividers.
