Q6600+XFX 680i LT help

[elec999]

I got my XFX to boot at 400x9 with Q6600. Only problem it will only boot at this, or even be stable at this, only with one ram stick. I tried planning with voltages but still wont be stable with two sticks. I have the good Buffalo Firestix ddr800. The system is perfectly stable at 400x9 with one stick running 4 seti@home boinc.
Thanks

Tried relaxing the timings of the sticks, with the Asus version we used to relax the timings a bit to keep it stable... but that's nice on an 680i, I used to run 425FSB but only 8 multi as the CPU needed 1.55 volts to go 9X and temps got a bit out of hand

425FSB on the Striker got some other strap or such like... as the NB voltage could be reduced to 1.4 volts again coming from 1.45 at 400FSB... (dual core as Q6600 never booted with me )

I did my best, all kinds of different playing around. Cas 5-5-5-5-20 or -15, the ram is at cas 5-5-5-x original, and tried 2t. Different voltages, this ram should do 1066 mhz at 2.2volts.

Well the 680i first design is limited there mate, if you run a quad keep the FSB and Ram speed in sync for best stability... they can do 1066mhz on another board with a quad not on a 680i... both sticks work fine when used alone ? have you tried other dimm slots ?

Yes I did. The ram seems to clock up to 1066 @ 2.1v when cpu runs at 333mhz. I want to try to get it it at 400mhz.
