Hello!
Topic question doesn`t have final answer on forums all over the net...

TIPS:
- compatible DDR3 by AMD support: 4x8GB 1600MHz SINGLE RANK [ http://support.amd.com/us/kbarticles/Pages/ddr3memoryfr... ]
- found compatible DDR3: KINGSTON KHX16C9K4/32X [ http://www.kingston.com/dataSheets/KHX16C9K4_32X.pdf ] ( only kingston.com has search filters like 'single rank' and 'double rank' )
- QVL list ASUS: doesn`t support that DDR3 but similar from KINGSTON

Questions:
- is that configure [ AMD + ASUS + KINGSTON ] will work fine ?
- where i can find more od DDR3 SINGLE RANK ?
- is anyone have config like: FX 8350 / SOBERTOOTH / 32GB DDR3 1600MHz (or 1866MHz somehow...) and it`s work fine and stable ?

THX for sample. But question is it work with config above at 1600 ? That Crucial is single or double rank ?

Your`s samples isn`t work fine - those models has errors with topic config / you can find some topic about this on some forums. Is it simple rank ?

Reasons to consider ECC RAM if one's motherboard and CPU supports it:

"...As the graph above shows, ECC RAM has a much lower failure rate than non-ECC RAM. The ~1% failure rate of the Kingston non-ECC RAM is still very, very good (which is why we primarily use Kingston), but the ECC RAM is even better at an average .24% failure rate..."

The use of ECC RAM forms the first line of defence against bit-squatting:

"...ECC support

The information in an ECC memory is stored redundantly enough to correct single bit error per memory word. Hence, an ECC memory can support the scrubbing of the memory content. Namely, if the memory controller scans systematically through the memory, the single bit errors can be detected, the erroneous bit can be determined using the ECC checksum, and the corrected data can be written back to the memory.

More detail

It is important to check each memory location periodically, frequently enough, before multiple bit errors within the same word are too likely to occur, because the one bit errors can be corrected, but the multiple bit errors are not correctable, in the case of usual (as of 2008) ECC memory modules.

In order to not disturb regular memory requests from the CPU and thus prevent decreasing performance, scrubbing is usually only done during idle periods. As the scrubbing consists of normal read and write operations, it may increase power consumption for the memory compared to non-scrubbing operation. Therefore, scrubbing is not performed continuously but periodically. For many servers, the scrub period can be configured in the BIOS setup program.

The normal memory reads issued by the CPU or DMA devices are checked for ECC errors, but due to data locality reasons they can be confined to a small range of addresses and keeping other memory locations untouched for a very long time. These locations can become vulnerable to more than one soft error, while scrubbing ensures the checking of the whole memory within a guaranteed time.

On some systems, not only the main memory (DRAM-based) is capable of scrubbing but also the CPU caches (SRAM-based). On most systems the scrubbing rates for both can be set independently. Because cache is much smaller than the main memory, the scrubbing for caches does not need to happen as frequently.

Memory scrubbing increases reliability, therefore it can be classified as a RAS feature...."
