no memory from Corsair longer available

I bought also the above-mentioned Board in June 2012. The board itself is amazing. Now I wanted to expand the memory. So far I have installed a memory (Corsair 4GB CMX4GX3M1A1333C9 Ver2.13). So ordered. Was delivered (Corsair CMX4GX3M1A1333C9 Ver2.20). With this, the Board is not running!
Corsair written, answer: Yes, the new store are high-density, and the old low-density (high-density 512x8, 256x8 low-density). The low-density memory from Corsair have 8 chips on each side of the board. The high-density have 8 chips only on one side. And very sorry, but we sell only high-density storage.
The board itself, however, can only low-density (256x8) address memory.
So tough luck. Board super and not yet old, but you get daführ no more memory. Super, again a functioning device for electronic waste.
