Registered ECC - unofficial support? Will it damage my system? 9590 - 990FX

Registered ECC - unofficial support? Will it damage my system?

Gigabyte 990FX-UD3 rev 4.1 motherboard,   9590FX CPU

This WS build needs ECC. I have some RECC (the 'R' = registered). I want to try installing it. Will this start a fire or kill my board? The documentation form Gigabyte and AMD are unspoken in specifically mentioning registered memory.

One would therefore assume that the RAM will have 3 expected behaviours:

1. Not post

2. Post, and function as ECC, with extra latency due to the registration buffer (physically on the ram module) consuming extra clock cycles

3. Kill my hopes and dreams.

Thank you for your time!

desktop PCs do not use registered memory, the key is will block installation

registered memory is used by servers with DDR3 to support using more sticks of memory which is done with an additional buffer to drive the signals

desktop pcs use the CPU signals to read and write RAM without additional buffers

Thanks hardcoregames™

For anyone else with the same question, I also learnt that the CPU also lacks certain features required to make signalling possible with Buffered/Registered memory, as there is an alternate signalling lane for the ECC. Instead of rehashing gibberish here is what I learnt somewhere else.

I doubt either hardcoregames or rebelyell will care much for this info, but for anyone with the same question, here's a definitive answer.
