What are you using registerred memory for? An Opteron/FX-51 system?

ECC is different thatn registered.

You can get registered that isnt ECC.

Unless you are running mission critical server, dont get ECC, you don't need it.

I am assuming that the timings matter the same an unbuffered memory, but someone back me up on this.

You can disable the ECC in bios.

There is an additional clock cycle with registerred memory, but it doesn't appear to be affecting the performance too greatly. Timings still matter, though tRCD appears (once again) to have a bigger impact on performance for nForce3 and KT800 chipsets then CAS Latency.
