New RAM is: CML16GX3M4A1600C9B   4x4gb, 1600 MHz, 1.5V.

I don't know why the computer doesn't accept the RAM, (won't start, just starts than instantly turns off)

From my notes:

Chipset
Intel X79 Express Chipset (Intel BD82X79 PCH)

Memory

DD3 Non-ECC Quad Channel supporting overclocked and XMP Memory

•DDR3-1333 PC3-10600
•DDR3-1600 PC3-12800
•DDR3-1866 PC3-14900

Minimum: 8Gb
Maximum: 32Gb

4x 240-Pin DDR3 SDRAM Slots for use with the following configurations:
•8Gb (2x4 Gb DIMMS)
•16Gb (2x8 Gb DIMMS)
•24Gb (2x8 Gb + 2x4Gb DIMMS)
•32Gb (4x8 Gb DIMMS)

------------------------------
Personally, I think new-memory 4x4gb-dimms should down-clock and work, but only if it's DDR3. However, I'm sure there are more compatible DIMMs out there. DDR3-1333 PC3-10600 is most compatible.

You could re-install the old working memory and take screen-shots of CPUz's Memory & SPD screens (and then match them closer).

The Aurora R4 only accepts 2 GB and 4 GB DIMMs.

But I don't know why those particular DIMMs aren't working. The R4 owner's manual says 1600 MHz RAM is supported.

Here's a CPU-Z screenshot of my R4, which has four 4 GB DIMMs:

Aurora R4 RAM - CPU-Z

If you do a search for that part number (HMT451U6AFR8C-PB) you'll find it on several sites, including Amazon, for around $25 per DIMM.
