Metamorphosis Step-by-Step
First, we seat the CPU in the A9S sister board. In this case, we installed an Athlon 64 3800+.
Next come the memory modules. We reached for two DIMMs from the American company OCZ, which support fast CL2-2-2-5 timing.
Around the Elite Bus socket you'll find 12 jumpers. If the CPU sister board is to do its job, all jumpers must be reversed, to let the card communicate with the Southbridge chipset on the motherboard.
After the A9S is fully assembled, it must be inserted into its intended slot.
Don't forget: the four-pin AUX connector for sister board power must also be hooked up to the sister board.
The next step is to switch over (or insert) the graphics card into the secondary x16 PCIe slot...
...because the primary slot only works with the Pentium 4 Northbridge. But because the A9S CPU heatsink impinges on that very space, the primary graphics slot becomes inaccessible anyway.
