The DRAM frequency is linked to CPU BCLK frequency, although 170 chipset should be capable to DRAM frequencies up to 3200 MHz with standard BCLK clock of 100 MHz, MB BIOS may change BCLK frequency earlier. BCLK frequency determine PCIE frequency (for lanes from CPU), so if it became more that standard, the PCIE clock will also be greater, so your SSD lost. Check the MB manual for details about frequency dependencies, also try to find a BCLK Frequency : DRAM Frequency Ratio option in BIOS setup.
Thanks I'll look into this when I get home.
I know I left the BCLK at 100. The SSD is in slot 5 which is an x4 slot fed from the PCH. Does the PCH use BCLK as well?
I don't recall seeing a DRAM ratio option. I'll look around and see if I overlooked it.
Did a look into chipset datasheet, according to scheme on p.175 of http://www.intel.com/content/dam/www/public/us/en/documents/datasheets/100-series-chipset-datasheet-vol-1.pdf CPU BCLK and PCIE base clocks comes from same PLL in PCH, so all PCIE slots are in one boat.
I verified if I changed the BCLK and keep the memory under 3000MHz it duplicates the issue. I didn't see any other ratio's though in the bios. Working with eVGA support right now to determine what's going on.
