A router can't magically increase NVRAM size no matter what firmware is running.
Sure it can

At times it seems to be a bit crazy --- but that is really a whole different topic.
The increased NVRAM size is a key part of dd-wrt broadcom k3.x ... it should not be a problem for you.
Unless my memory is wrong, then why does the CFE show a different NVRAM available size?
I flashed a 32K build from the start (21605) but it changed total to 128K. Later builds doubled it. I didn't flash any tailored build that said 64K or more. In fact, the custom builds for this router don't even work as DD-WRT will report instantly flash successfully upon uploading the firmware via webGUI. _________________ ASUS RT-AC68R: 42954

You're thinking of the base nvram partition; k3x builds expand it in the application code.

That normally happens when the build size gets too big for your router/model (and also if I try to use the 'reset after flash' option).
E.g. the 28647 k3x builds are too big, but 28598 flashes on my WNDR4000 (has other issues, but that's another story). _________________ #NAT/SFE/CTF: limited speed w/ DD#Repeater issues#DD-WRT info: FAQ, Builds, Types, Modes, Changes, Demo#

Oh so that explains why running "nvram erase" in DD-WRT can spell disaster.
As for build size, I'm on the latest version mega Broadcom generic. However, if I try flashing the F7D7301 tailored build, I get the instant flash success with zero changes and sometimes increased NVRAM consumption. _________________ ASUS RT-AC68R: 42954

a few devices. lets call them linksys (not all, but some) should not be treated with "erase nvram", since they wont recover the default data sometimes. i have seen lost mac addresses etc. this is why dd-wrt is also not erasing the flash anymore, but just restoring the default data if selected and keeping factory values untouched _________________ "So you tried to use the computer and it started smoking?
