Gekkoscience R909 Bitcoin SHA256 USB Pod Miner 1.5TH

This miner is built with the same physical dimensions as the R606 so anything built around them would still fit this unit. Airflow ducting is the same, same 80mm fan. However, you’ll notice ports and jacks are located at the exhaust end instead of accessible from the side. Designed to be stackable, you no longer have to keep three sides clear – two for airflow and one for cabling. The R909 has been upgraded with a better main regulator and improved thermal management. Heatsink area over the chips is increased by 40% over the R606.The Terminus R909 needs an external controller running cgminer, with USB connection to the miner (a 6-foot USB cable will be included with purchase). The driver has been tested extensively on linux PC and Raspberry Pi. Like previous Terminus models, the miner runs on 12V power from either a standard 2.1/5.5mm barrel jack (rated for 8A) or a PCIe 6-pin jack.The "stock" speed will be set to 400MHz, expected to see 1.6TH, but higher frequencies are possible.This miner also features Blinky Lights, but they're not as intrusive as previous models of pod or stick. The rate of blinking is proportional to hashrate. The base light color is a delightful pink-magenta.The BM1397 chips have a significant temperature coefficient, which means that they pull noticeably more power as they get warmer. Nobody at GekkoScience will be offended if a tuner or enthusiast upgrades the fan, as more airflow could mean reducing power consumption by 5-10% just from maintaining lower temperatures. These units take a standard 80mmx25mm 3/4-wire 12V case fan. And like all GekkoScience products, the Terminus R909 is Made In The USA. Approximate dimensions: 3.5 x 4.2 x 6 inches.

Doc fetch goes through Layer's Aerospike pull-through cache; cache hit served the row without touching turbopuffer. The similar query re-embeds this product's title with CLIP-text and runs a vector query — queries don't go through the doc cache, so no cache header is set.
