I think cleupon has some 3rd party modules that are known to work.
Running 9.6 mine looks as follows with 128M on the CFEB:

I just looked and mine is only 128M on the CFEB.
As with the RE, is there a third party memory upgrade that could be bought?
Part Numbers welcome.

Sounds like we'll need the RE-850 if we want to take more than our 2 full
feeds
though -- although others have said we may run out of CFEB RAM first? Excuse
the newbie question, but what is the CFEB RAM used for -- we have one router
with one full feed and the CFEB is at 42% RAM, another with two full feeds
and
the CFEB is at 42% also...
The CFEB memory utilization you get from "show chassis cfeb", e.g.
CFEB status:
State Online
Intake temperature 39 degrees C / 102 degrees F
Exhaust temperature 46 degrees C / 114 degrees F
CPU utilization 11 percent
Interrupt utilization 0 percent
Heap utilization 26 percent
Buffer utilization 27 percent
Total CPU DRAM 256 MB
is only part of the story. This shows the DRAM memory on the CFEB,
which is used for the operating system kernel running there, a copy
of the RIB, and some other stuff.
What is equally important is the high speed memory used for packet
pushing (static RAM for the traditional CFEB), which is a rather
small amount, and which you only see if you login to the CFEB and
use the "show jtree 0 memory" command. E.g.:
CSBR0(ar1.xxx vty)# show jtree 0 memory
Memory Statistics:
8388608 bytes total (2 banks)
5017384 bytes used
3371224 bytes free

This memory holds the FIB, nexthops and similar stuff.
Notice only *8 Megabytes* total, and about 60% of this memory in use
in the example above. If you run out of *this* memory, your box is in
real trouble.
The "plain old" M7i/M10i CFEB comes with 128 MBytes of CFEB DRAM,
which can be upgraded to 256 MBytes. 256 MBytes is mentioned as a
requirement for JunOS 9.x.
The CFEB SRAM cannot be upgraded (but you can buy a new enhanced
CFEB instead...)
