Can Taichi x399 handle a 32GB sized Ram Stick£

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I looked all over the internet and I can't find the answer.

I have Taichi x399 motherboard with AMD Threadripper 1950x.

 Taichi x399 motherboard supports max of 128GB of Ram.
 Taichi x399 motherboard has 8 Dimm slots.
 But how big can each ram stick be? Is the max 16GB dimms? 

I'm trying to max out the ram to the maximum 128 GB limit. Should I go with 8 sticks of 16 GB each, 8x16=128, or 4 sticks of 32 GB each, 4x32=128. 

Thank you so much!

	http://event.asrock.tsd.com/ Ask ASRock Tech Support if the RAM you are considering will work in the config you intend to use. More often than not, if they have the kit you are considering in their lab, they will test it with your board model for you. Be sure to list a model number for the kit you are considering. It may well be possible to install 256gb of RAM on your board, 32gb RAM modules did not exist when the board was released.

	They got back to me, they said no. The maximum sized RAM stick is 16GB for the Taichi x399 regardless of bios updates. So future readers know. NO you cannot put 32 GB sized RAM sticks in this motherboard. 16GB sized sticks and below only.

	looking at bios programing papers for zen 1, there is reserved space for DRAM adress mapping, since 3 bits are there reserved for future, cant you just add it? or it needs support from amd first? page372https://www.amd.com/system/files/TechDocs/55072_AMD_Family_15h_Models_70h-7Fh_BKDG.pdf Edited by kerberos_20 - 15 May 2022 at 1:05pm
