Small FFT
This test uses data that fits completely into your CPU's level 2 cache, it stresses the processor intensely but does not stress the RAM or the link between the RAM and the processor. It will error out because of:
Not enough vCore
Possibly low CPU Termination (VTT)
Possibly low/high CPU ref
Possibly low PLL (clock generator) voltage
Large FFT
This test uses large "pieces" of data that require information to be moved in and out of RAM quite intensely to constantly feed the processor. The data in these calculations doesn't fit completely in CPU onboard cache, so the work load on the MCH and RAM is huge. It will error out because of:
Not enough vDIMM (RAM voltage)
Not enough (and rarely too much) MCH core voltage
Incorrect MCH ref voltage
Unstable memory timings (includes both main timings ie 5-5-5-15, and also tRead and tRFC.
Only fails because of processor when vCore is waaaaaay too low!
Blend
This alternates between small and large data sets, and although it is a useful "last test" when run for say 24 hours after you believe you have everything dialed in and it passes Large and Small seperately, it's confusing for fault finding.
If Blend fails it could be for any reason mentioned for small FFT and large FFT leaving you with no indication what to do to stablise the system.
