What is the maximum amount of supported ram?

32bit kernel: 4gb
64bit kernel: I'll need to check that, but at least 256tb.

I found 128 tb / process for 64-bit due to Intel MMU limitation. Article is 3 years old, maybe there is a new limit with new CPU's.

As far as I can tell "TinyCore" is only 32bit. There is no 64bit "TinyCore". Which would mean that any version of "TinyCore" can only handle a maximum of 4gb of ram. Am I incorrect? Please tell me I am incorrect!?  :'(

Hi d.custer
You might want to take a look here:

So during install just replace "core.gz" with "core64.gz"?

wondering in how many decades tasks under tinycore will consume at least half of these 256 terabyte? :)

You also need the vmlinuz64 64 bit kernel.

I know this is an old thread, but there seems to be no confirmed answer. E.g. some linux flavors have 128GB limits. Does the microcore kernel have similar limitations? Running 'dmidecode -t 16' produces 4GB on a 64-bit kernel.

Isn't it a CPU limit only ?

dmidecode reads your BIOS and motherboard info, I think that value is the max your mobo will accept.

Thanks, the machine has 6GB so it might be a process limitation due to this dmidecode being the 32-bit version. Looks like the only way to really find out is to test and see what happens at 64GB, 128GB, 256GB. Easier said than done.

Thanks again
