The memory matrix for the T610 doesn't list a configuration for 32GB in Optimizer mode, only Mirrored or Advanced ECC. There are 36GB configurations, however. This would use 6 DIMMs per side, combining 4GB and 2GB DIMMs. My recommendation would be to switch to the 36GB in Optimizer mode, because Advanced ECC and Mirrored modes will have some of the capacity put to use outside the OS' reach. If you want to go this route, it would be A1-3 and B1-3 with 4GB DIMMs, and 2GB DIMMs in A4-6 and B4-6.
Basically, optimized is set up to allow for all the memory to get passed through to the OS. Advanced ECC is there to provide additional protection of DRAM chip failure.
thanks for the reply. what are the advantages for optimiser over advanced ecc? seems silly that i have to remove 2x4gb and replace with 6x2gb too get this to operate properly! thanks

This is from another server, but the information still applies.
Advanced ECC mode: https://www.dell.com/support/manuals/us/en/04/poweredge-r720/720720xdom-v3/advanced-ecc-lockstep?guid=guid-984f2b7a-cdb4-48aa-8eea-9fb6eaf2f789&lang=en-us
Optimized mode: https://www.dell.com/support/manuals/us/en/19/idrac7-8-lifecycle-controller-v2.30.30.30/720720xdom-v3/memory-optimized-independent-channel-mode?guid=guid-4e0d57eb-0369-4d2f-9b34-9cf1ce1058b5&lang=en-us
