Is any kind of firmware upgrade required when upgrading the 2 dram chips that are at the front part of the sup7203B. I am taking out the 2 that are in there now and installing 2 1g chips. I know that a firmware upgrade is required when upgrading the sup-bootflash: but how about the msfc3 dram?
I hope you are fine, complete these steps to simulate a break key sequence to enter the rommon:
1.Connect to the router with these terminal settings:
1200 baud rate
8 data bits
1 stop bit
No flow control
You no longer see any output on your screen, and this is normal.
2.Power cycle (switch off and then on) the switch and press the SPACEBAR for 10-15 seconds in order to generate a signal similar to the break sequence.
3.Disconnect your terminal, and reconnect with a 9600 baud rate. You enter the ROM Monitor mode.

I hope that everything is going fine with you, here you are a nice link on how to configure the online diagnostics on the Catalyst 6500 series switches:

When issuing the show version the memory shows two values, separated by a slash, are given for DRAM:
The first value tells you how DRAM is available for system processing, and the second value tells you how much DRAM is being used for Packet memory.
The first value, Main Processor Memory, is either:
- The amount of DRAM available for the processor, or
- The total amount of DRAM installed on the system.
The second value, Packet Memory, is either:
- The total physical input/output (I/O) memory (or ?Fast memory?) installed on the router (Cisco 4000, 4500, 4700, and 7500 series), or
- The amount of ?Shared memory? used for packet buffering. In the shared memory scheme (Cisco 2500, 2600, 3600, and 7200 Series), a percentage of DRAM is used for packet buffering by the router's network interfaces.
NOTE: The terms ?I/O Memory? or ?iomem?; ?shared memory?; ?Fast Memory? and ?PCI memory? all refer to ?Packet Memory?. Packet Memory is either a separate physical RAM stick/module (?), or shared DRAM.
HTH, please rate if it does help,
I really don't know why do we have to disagree at all, below are 2 separate documents explaining both:
Here you are the DRAM DIMMs "Removing and Installing the DRAM DIMMs":
SP and RP DRAM DIMMs near the front.
Here you are the BOOTFLASH DIMMs "Installing the CompactFlash Adapter":
SP and RP BOOTFLASH DIMMs near the back.
NOTE: Both DRAM and BOOTFLASH are physically DIMMs (dual in-line memory module).
