As you said a 2 beep error code is no ram or faulty ram.
If you have tried known working compatible ram modules and it still fails then perhaps the first thing to check is if there is voltage being applied to the ram slots so that they can function and communicate with the chipset. [br]
The schematics show that the ram slots are tied directly to the chipset. (See block diagram on p.1 of the schematic, linked below).

Given how close together the contacts are in a ram slot, initially it may be safer to test that the ram voltage supply is on the motherboard before checking to see if it appears at the ram slots. (see p.48 and p.96 for further information about 1D35V_S3 & DDR-VREF_S3 voltages)
