Erm.....no, sorry. The Addresses are the same way round in both commands, as 
it says in the MRM

On a Master 128, go to Mode 0, fill the screen, with *H.. for example, and 
try

*SRWRITE 3000+4000 8000 6
cls
*SRREAD 3000+4000 8000 6

Will write 16k on the screen to bank 6, then read it back again.

I would suspect the problem you're getting is using the 9, it's not picking 
it up as a valid RAM address, and it certainly isn't on a Master, as it's 
RAMs are 4 5 6 & 7, providing the internal jumpers are set to RAM (left) and 
not ROM space (right).
