Usually the SPD on these sticks is set loose to allow booting at 1.8vdimm ,mine are
8-3-3-3 @200
11-4-4-4@266
13-5-5-5@333
Maybe yours have a different SPD programming?
Weird. My sticks don't have the 266MHz SPD. Instead it has a secondary 333MHz code with tCL4:
8-3-3-3@200
14-5-5-4@333
14-5-5-5@333

I flashed the other stick with an SPD image from a DDR800 binned Team D9GMH stick, flashed stick now has:
8-3-3-3@200
11-4-4-4@266
16-5-5-5@400
-> no go on the abit.

But the board does not boot with either module.
My old crummy Gigabyte 965P-DS4 works "fine" with both the stock and the flashed one.

Guess I'll be trying different combination of sticks and slots...
