extra RAM sticks on server board
I have a Supermicro X10DRi-T. http://www.supermicro.com/products/motherboard/xeon/c600/x10dri-t.cfm
There are 8 RAM slots available to CPU 1 and 8 RAM Slots available to CPU 2
It has 1 CPU fitted.
It already has 4 x Samsung 16GB PC4-2133P RAM Modules (64GB Total) fitted. So the 4 x 16GB RAM modules already fitted take up 4 Slots
I would like to add another 4 modules of 32GB RAM to give an extra 128GB of RAM.
So the extra 4 x 32GB of RAM would be added to the second bank of 4 RAM slots available to the CPU 1
Is it OK to mix up RAM Modules like this ? 4 x 16GB in the first 4 slots and 4 x 32 GB in the second 4 slots available to CPU 1?
They are/will be matched sets of RAM Modules in each bank of 4 slots.
So not sure if the different sizes of modules in each bank of 4 slots is a problem or not

Out of personal curiosity, what kind of application is running on that system that wants 192 GB of memory?

128GB is for a RAM DRIVE to write video files to while working on said files.
An SSD would be cheaper and more reliable. If a stray cosmic ray goes through that 128 GB, all of a sudden the file unlucky enough to be on that section of memory is corrupt and unrecoverable. SSDs have extensive error checking; RAM drives have none at all.

yes i do realise all that - however 4K video generates HUGE amounts of data. The idea here is to ingest to the 128GB RAM drive as it has unlimited write cycles - SSD's typically have around 300TB of writes before death. Enerprise SSD's go as high as around 800 - 1000TB's before write death.
What we do is ingest footage and throw 3/4 of it away and do not retain it - only the very very highest quality footage is keep. Thats a LOT of writing out to SSD to then throw away. We can easily generate a 1TB + plus per day of footage.
Other uses are to select a clip , load into RAM then work on it then write it out to HDD when done. The RAM read/write cycles are unlimited and uber fast. Nothing comes close to this for the money.

As long as you stick to the same technology you can mix sizes and speeds. You can't mix RDIMMs with LRDIMMs.
Not sure what you mean by "first 4 slots" you would put the 16GBs in the blus slots and the 32GB ones in the black slots (or vice versa) to keep the same amount of memory on each channel for better RAM bandwidth.

Thanks for your comments - yes you are correct - i looked at the photos to the server (its in a DC) and the RAM sticks are the slots as you mention. I thought they all went into the slots on one side of the CPU - hence asking here.
I've never added anything to a server before so first time for me.
Thanks for the help.

@ andyalder,
Just to be clear - i can mix 16GB and 32GB ram sticks as long as (in this particular case) the 4 x 16GB sticks go in the Blue slots and the 4 x 32GB Ram sticks go into the black slots ? No issues caused or any impediments caused by this type of setup?
There is no loss of speed because of different size DIMMS etc ? I do realise that the RDIMMS all have to be the same ie, RDIMMS, of same speed and ratings etc. I was just concerned that the different sized RDIMMS might be an issue.
If you could just confirm this, i can close this thread and take your answer as the correct one.
many thanks
