# tt_dram_speed_mbps [<< Home](../index.md) | [<< Metrics](../metrics.md) ## Name ### Prometheus Metric Name ``` tt_dram_speed_mbps ``` ### Metric Path (tt-telemetry) Schema: ``` {hostname}/tray{tray}/chip{chip}/dram/tt_dram_speed_mbps ``` Example path: ``` bh-glx-c09u02/tray1/chip2/dram/tt_dram_speed_mbps ``` ## Description The DRAM data rate in megabits per second (Mbps). This is the speed at which the GDDR memory is operating, reported at the chip level. This metric is only created if the device reports DRAM speed data. ## Values **Type:** Unsigned Integer **Units:** Megabits per second (Mbps) **Allowable values:** A non-negative integer representing the DRAM data rate. For example, `28000` means the DRAM is operating at 28 Gbps. ## Prometheus Labels |Label Name|Value| |---|---| |hostname|The host from which the metric was collected.| |hall|The datacenter hall where the host is located. Sourced from the Factory System Descriptor (FSD).| |aisle|The datacenter aisle where the host is located. Sourced from the Factory System Descriptor (FSD).| |rack|The rack number where the host is located. Sourced from the Factory System Descriptor (FSD).| |shelf_u|The shelf U position in the rack where the host is located. Sourced from the Factory System Descriptor (FSD).| |tray|The tray (UBB) that the device is located on.| |chip|The ASIC location within the tray.| |unit|The unit of measurement. Always `"Mbps"` for this metric.|
