32 Spartan6 LX150 FPGAs in single device Now let's see who first turns that into a mining rig or something similar ;D Title: Re: FPGA HPC :P 32*LX150 Post by: Inspector 2211 on March 07, 2012, 09:32:21 PM Noticed this: http://www.sciengines.com/products/accelerators/formica.html 32 Spartan6 LX150 FPGAs in single device Now let's see who first turns that into a mining rig or something similar ;D The data sheet says "200 W power supply". No, you cannot run 32 Spartan6-150 FPGAs off a 200 W power supply while mining. Mining consumes about 8 to 9 W per FPGA.

No, you cannot run 32 Spartan6-150 FPGAs off a 200 W power supply while mining. Mining consumes about 8 to 9 W per FPGA. Didn't check in that much details. Simply swap the PSU. Then again, cooling probably hasn't been made to match :( Title: Re: FPGA HPC :P 32*LX150 Post by: Glasswalker on March 08, 2012, 02:02:51 AM Also their cost per MHash is quite high if I remember correctly... I evaluated their gear some time ago. They also have a rackmount solution that has a ridiculous number of FPGAs in it, but it's not cheap. (compared to the current options like Icarus and X6500, or the BFL gear)

Title: Re: FPGA HPC :P 32*LX150 Post by: Wandering Albatross on March 13, 2012, 07:43:55 PM Quote from: Inspector 2211 13 Spartan chips per board, 50W per board -> FAIL From the site: "Power Consumption The PCI Express specification limits slot power to 25 watts. The DNBFC_S12_PCIe is capable of consuming power significantly beyond that. In addition to the PCIe fingers, a separate HDD connector adds a second path for power. This product is shipped with adequate heatsinking to consume 75 watts, but airflow is required in the chassis to dissipate the heat. Contact the factory if you require high reliability, no-fan heatsinks." That thing would need lots more cooling. Title: RIVYERA FORMICA Miner - up and running Post by: blackice on July 07, 2013, 11:24:28 PM I am mining on Slush's pool using a Rivyera FORMICA. One hash per clock. 80MHz. 32 x S6LX150. Averaging 2.5GH/S total according to Slush. Controller backs the clock off if card temp exceeds 50C. It could run faster if I had larger heat sinks and higher capacity switchers on the backside.

Take a look at the FPGA miner github if you're interested in seeing some other implementations, if you got cooling/power sorted you should be able to get 6.5+ GH/s out of it. ;) Title: Re: FPGA HPC :P 32*LX150 Post by: blackice on July 08, 2013, 05:10:44 AM Wow, old post.

Title: Re: FPGA HPC :P 32*LX150 Post by: volosator on July 08, 2013, 12:04:37 PM you can mine litecoins with it assuming you have right bitstream - boards have memory attached to each FPGA!
Title: Re: FPGA HPC :P 32*LX150 Post by: blackice on July 09, 2013, 02:32:08 AM @volosator, that is a very astute observation, and a very good idea! How did you know that?
I will need to write a Scrypt machine. Any suggestion where I could get some info on Scrypt?
