1) C32/G34 socket twin boards need to use our Supermicro chassis. In the bare-bone server, they already come with Supermicro heatsinks that do not require retention.
2) H8DG6/I(-F), H8QG6/i(+)-F,H8QGL-6/iF(+), and H8DGG-QF MBs cannot fit the retention due to the physical space limitation, so we don’t include the retention parts in packing.
It is recommended to use proper Supermicro heatsink for Supermciro C32/G34 socket MBs.
