Ballistix + A8N-SLI Deluxe + Venice - Help

[saboya]

I recently bought a pair of Ballistix modules (512mb each). They're not a 2x512 dual kit, I bought them as separate modules... To later find out that they don't work well togheter :(

Here are some screenies to illustrate my problem

These are results with only 1 module installed:

200mhz 2-2-2-8 (rated memory timings):

250mhz 3-3-3-8 (didn't try to lower the timings, testing purpose only):

270mhz 3-3-3-8 (same):

I tested with ALL the memory slots, all worked just fine. Tested both modules, both performed just the same.

Now, dual channel settings:

200mhz 2-2-2-8 (I forgot to bring out the CPU-Z timing window, doh):

I was very happy with my modules, I paid almost nothing to change my old crap TCCC for this, and it ran at 270mhz, just sweet! But then I did the bandwidth tests and, that came up :/

I also tested with different BIOS, got the same result.

Now, my question is:
1 - Does micron chips have any incompatibility issues with the A8N-SLI Deluxe?
2 - Does micron chips lose that much efficiency when working in dual channel?
3 - There could be an incompatibility between the memory and the controller on my Venice? (Venice 3000+ 0516, 2700mhz @ 1.5v)
4 - None of the above is true, I just got unlucky and my modules don't work well togheter.

Any input is appreciated... Thanks in advance. :)

Do you mean that the bandwidth isnt totally doubled? Please clearify.

I mean the efficiency is very low... 270mhz 3-3-3-8 is supposed to have about 7000mb/s bandwidth at least.. All the other timings are as low as possible. 5000mb/s with 200mhz 2-2-2-8 is VERY low imo. I'm down at least 500mb/s on those benchs, don't you agree?
