Questions about this item

Will the flash memory on this Ultra 80 E420R motherboard need replacement after a certain number of write cycles?

The flash memory is built into the motherboard and has no user-serviceable replacement interval; it is intended to last the service life of the board under normal firmware storage use.

What limit appears first when this Ultra 80 E420R motherboard runs continuously under load?

The first limit is the thermal capacity of the passive heatsink design; sustained high CPU utilisation will raise onboard temperatures until throttling or shutdown occurs.
