dz77re-75k won't post led error 32 with 3 beeps

Hi

I bought this board to replace ASUS, CPU 2600k tried 3 diff configs of 16G DDR3, 1333, 1066. I understand the limits of the 2nd Gen Procs but won't post!

1: 3 beeps and  error code 32 ? not listed anywhere

2: Status LEDS blink green MEM while beeping, flashes red HOT then shuts off

I disabled or disconnected video card ASUS 6950 and 1 add on eSata adapter

Do I need to return this board? I know it is older board without support but anybody else worked through this?

Thanks in advance
