Please help me understand if this is going to be a problem. This is related to another post that was answered previously. I had tried to upgrade my system for heavy load of rendering, and there was a problem when I received the new RAM.

Previously answered in : Is it safe to use RAM sticks with different frequencies?

My question is after the screenshots attached below:

2 Different modules

My Question:

Amazon shipped me a DDR4-2666 RAM module instead of a 2400 Frequency, which my system was originally shipped with. So, as per the previous answer, the superuser(‘nik’) mentioned, “2. The modules will not be acceptable by your board together and it will declare memory failure.”

So if I keep a huge file for rendering which may take about 36 to 48hrs, will this crash my system in midway? Should I even be concerned about it happening? Or is it going to be just fine if I continue with it?

is it safe to use RAM with 2 different frequencies

YES, the higher clock speed DIMM will underclock itself if possible to that of the lowest speed DIMM. If the motherboard POST's (power on self test) and gets to the BIOS screen, then the RAM DIMM combination your using is valid and safe. It would come down to DIMM's meeting JEDEC standards... and if different DIMM's meet a given standard then that's what matters.

for example a DDR4-3200 underclocking or downclocking itself to DDR4-2933 does not make it or any other DIMM less safe or more prone to error. If anything downclocking would make things more stable... it's when u overclock that things overheat and become more unstable.

all the ram dimm's on your mobo must run at the same voltage, speed and timings.

no

no

yes

sacrificing speed for reliablility you would want a highest speed rated ram (which has passed the quality control to run at those highest speeds i.e. ddr4-3200) and then manually downclock it to the lowest compatible setting via XMP (the opposite of what overclockers do)
