Description: The largest available continuous block of DRAM available on the host device, in kilobytes.
What is ocStbHostLargestAvailableBlock?
Reports the size, in kilobytes, of the largest single contiguous free block of DRAM on the device, a more useful memory-pressure indicator than total free memory since heavy fragmentation can leave plenty of free memory but no single block big enough for a large allocation.
