I manually seted the RAMs on DDR800, and played a little with some options in bios like the transaction booster, and vdimm, but it wont boot while trying to use dual channel (slots 1 and 3), while it works fine on slots 1 and 2, but that means no dual channel

I read something here, about the SPD configuration and than that might be the problem, the last mems that i tweaked where DDR1 and im sort of clueless here, anyone knows something about this problem and/or how making changes on the spd might help me?

Get in the BIOS and manually set:
timings: 5-5-5-15
vdimm: whatever the manufacture suggest prolly 2.0-2.1v
NB Voltage: 1.55

This should get you going in dual-chan mode, also you might try slots 2 & 4.

Oh and for now disable Trans-Booster, and Static Read until you get it
working, then you can start to tweak it for performance.

As for the SPD that may help, But you'll have to narrow the problem down
b4 you even think about fixing it there.

I fixed my OCZ modules by hacking the SPD. The problem I was experiencing was that the p5k-e would undervolt my mem at 800mhz, so I edited the
SPD on my modules to make them appear as 666mhz, so when the mobo read the SPD it would run them at 666mhz @ 1.8v, and then I just go and set
them to 800mhz @ 2.1v manually.
