When referring to the gige card do you mean the GE-GBIC-SC-B ?
As far as I know that's the latest gige card for the gsr family.

I have a gsr8/40 with an ordinary GRP (the fist version / a-version) that
has only 256Megs of ram and runs 3 full views. currently there are 27479020b
free so I can hold about 200.000 routes I'd expect. Soft-reconfiguration is
disabled of course since this would cost about 10 to 15 MB Ram.

The limit might be my ge-gbic-sc-b card since it has only 128MB route
memory.
  FRU:  Linecard/Module: GE-GBIC-SC-B=
        Route Memory: MEM-GRP/LC-128=
        Packet Memory: MEM-LC1-PKT-512= 
On the linecard itself there are 10759088 bytes free so that's 10 MB and so
I'm going hit the limit sooner or later. Argh.

Looks like I'll have to filter out all those nasty /24 and /23s.

I'm currently looking for another Cisco.
What would you say: GRP with 256MB or GRP-B with 512MB?
GE-GBIC-SC or GE-GBIC-SC-B. Both have 128MB but can be upgraded to 256MB. Is
that necessary... And what do you think: when will this happen?

Thanks,
Gunther
