This might have been beat to death, but I'm unable to find a solution that suits my needs. Most people seem to be answering "Just use 16GB" or "use 1333MHz because it's virtually the same."

I'm looking to upgrade to 32GB while keeping the same CPU: AMD FX 8370 125W AM3+. Currently I'm not able to find a board that supports 32GB of 1600MHz ECC DDR3 using 4x8GB modules. The support lists for every motherboard I check doesn't show anything in that area. I'm not interested in overclocking any part of the system nor am I interested in dropping to 1333MHz. It's bad enough that I'm resorting to 1600MHz to begin with because I chose not to go with Intel where I could be using RAM beyond 2100MHz.

There must be a board out there that will run this amount of memory and run stable and reliably. I'd really like to avoid switching to Intel but if I must then that would really suck.

Thanks.

AM3+ FX CPUs support 1866MHz speed with one DIMM per channel or 1600MHz speed with two DIMMs per channel.

You need to check the motherboard specifications and manual for ECC information.
For Example:
Asus M5A97 R2.0
Specifications:
4 x DIMM, Max. 32GB, DDR3 2133(O.C.)/1866*/1600/1333/1066 MHz ECC, Non-ECC, Un-buffered Memory

Chapter three of the downloadable manual shows Memory Configuration and that ECC Mode is enabled by default.

Once you learn to read the motherboard specifications and manual you need to learn how to set up the memory clock, DRAM Timings and DRAM voltage. Memory runs at SPD (Serial Presence Detect) ratings unless changed by user. The The SPDs of the following memory are programmed to JEDEC standard latency...

The "ECC" part is kicker here, it's reserved for servers and with AMD it needs server class CPU.
Otherwise, FX processors have default 1866MHz MC and can run even faster memory and all AM3+ MBs with 990 chipset and 4 RAM slots support 4x8GB RAM which with some OC can go even considerably faster than 1866MHz.
