What is the maximum RAM supported by RouterOS in x86 server?
X86 Support MAX 2GB of RAM
https://wiki.mikrotik.com/wiki/Manual:RouterOS_features#Hardware_Support
so there is no use if we use high-end server like
Dell PowerEdge R410
Intel Xeon Hexa Core x 2 CPUs(12Cores,24CPUs)
32GB RAM (Support Upto 128 GB RAM)
1TB (Support upto 8 TB) HDD, Dual 1Gig LAN
correct me if i am wrong
You can use more than 2GB of RAM in RouterOS v7, by installing it in UEFI mode (added since v7.0beta5)
