4500 Oversubscription question

Hello Just curious if anyone has done any troubleshooting on packet loss over the uplinks to the asic on 4500 platform. We are running WS-X4548-GB-RJ45 modules which has an 8:1 oversubscription with 6 gbps but I want to verify drops on the uplinks to the backplane per port group. Currently running 12.2 ios on sup 4. Thx ~Bill

Is should be 8 ports per gig.  Or to quote Cisco's data sheet:

Bandwidth is allocated across six 8-port groups, providing 1 Gbps per port group
