I get a solid 225 out of the ones I've tested, they heat up quick but the fans kick in hard and the bottom of the Terminus only hits around 65C (infrared thermometer). Its stable and the Hashrate actually fluctuates between around 77Gh and 140Gh (averages 96)
"0: GSE 10030054: BM1384:8 225.00MHz (1/19/43/0) | 110.2G / 96.41Gh/s"
I run from a 6A powerbrick. From a stack of China made test units, its the most reliable Ive used so far. It gets a little hot so I know its not that efficient. I have that and a 5A that is reliable to, not sure what the exact pull is, I dont have a clamp meter and im too lazy to buy a KillaWatt.
the 6A is a "LX1206" made in china and the 5A is a "HTY-1205000"

Awesome. Thanks 419M that does help and confirm what I am getting also. I can't get past 225Mhz on the 6A brick that came with it but it does seem to running pretty well though at 225. For my other one I am experimenting with a more efficient and stronger supply and have it running at 237.50Mhz for just over 100Ghz which is my goal for each Pod. http://preview.ibb.co/cUPzqH/Term2_237.jpgIt is a 150Watt 12V supply with voltage adjustment. The one on the left is using the PCIe-6 connector and the barrel still on the right. The barrel won't supply as much reliably so I am going to convert that one also to see if I can run them both a little higher. http://preview.ibb.co/mp50xx/Term_Power_Supply.jpgUsing 123 watts with 1 running at 237.50Mhz and 1 running at 225Mhz https://i.imgur.com/rjWuBRS.jpgJust for info, these pods seem to run at frequencies in 6.25Mhz frequency (just like the antminer S3s and S5s) which is a function of the 1384 chips in the Terminus and looks like VH has support for those frequencies as well in CGMiner (thank you sir!!) So here is a list of frequencies to try if you want to test and push just a little bit more. I can't get either of my pods to run at 250 Mhz even using the PCIe plug and the 150 watt supply by itself. The most I can get is 243.75. Will test some more when I get time but I have a feeling its a limitation of the voltage regulator. Solid build Sidehack so thank you and not complaining at all just testing the limits for the ones I received. 200 Mhz 206.25 Mhz 212.50 Mhz 218.75 Mhz 225 Mhz 231.25 Mhz 237.50 Mhz 243.75 Mhz 250 Mhz 256.25 Mhz 262.50 Mhz 268.75 Mhz 275 Mhz Hope that helps somebody out.

I am also running on 225Mhz with an avg of 97Gh/s, pods are kool to the touch and have not tried to run higher than the 225Mhz. They have at least a month or more at 225Mhz, I just recently changed pools and started to see a few errors but nothing to be worried about. I originally had four running stock settings but two of them went zombie and could not get them back. ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fi.imgur.com%2FaBXhkDL.png&t=665&c=QNP1OTYxmEL3BQ)

I am seeing about 60 watts total per pod (10-14 just running and not hashing) so that would be 540 watts total for 9 pods. So to run at 80% capacity you would be able to run 6 pods for 360 watts.

Wow 60 Watts? what frequency are you running at? According to SideHack's power chart, 60 watts is 275MHz 100MHz (44GH) 660mV/node 2.64V total; 12V 1.4A for 16.8W/0.38J/GH 125MHz (55GH) 660mV/node 2.64V total; 12V 1.7A for 20.4W/0.37J/GH 150MHz (66GH) 660mV/node 2.64V total; 12V 2.0A for 24.0W/0.36J/GH 175MHz (77GH) 693mV/node 2.77V total; 12V 2.5A for 30.0W/0.39J/GH 200MHz (88GH) 715mV/node 2.86V total; 12V 3.1A for 37.2W/0.42J/GH 225MHz (99GH) 755mV/node 3.02V total; 12V 3.8A for 45.6W/0.46J/GH 250MHz (110GH) 770mV/node 3.08V total; 12V 4.4A for 52.8W/0.48J/GH 275MHz (121GH) 770mV/node 3.08V total; 12V 4.9A for 58.8W/0.49J/GH Ill pick up a P3 Killawatt on my way home from work tonight and see what I'm pulling per pod. But even so, then just jump to a 750Watt, its still the same common slot power supply, still under $40 https://www.amazon.com/HP-599383-001-Common-Platinum-Supply/dp/B00719064I/I've used the 1200Watt and Sidehacks break out board for GPU builds and AntMiners, its a solid reliable design. (those are just crazy expensive right now)

ok, I just re-read your post above, so your saying your pulling 60 Watt at the wall, and getting 80% efficiency at the power brick? 60Watt -> 48watt (225Mhz)?

Close. The power brick is 72 watt at 6 amp and yeah pulling 58.4 watts per pod at 225Mhz. The 750 would run at a better efficiency for sure. I'm at 123 watt for 2 pods on a 150 watt supply but it's getting too warm so I might go higher. Good Luck and let us know how it works out.

How is the noise on the power supply fan? How would I run multiple Terminus R808 using the one power supply? I tried running stock at 300Mhz, and it kept downclocking to 200Mhz and moving between 200-300Mhz. I seem to get more stable hash rate (~85GH/s) leaving it at 200Mhz.

I've never successfully run one above 275MHz, and I built the thing. 300MHz, unless you get lucky with the chips and can tweak the voltage down (or keep that regulator module cold), is probably unattainable.
If you see an unexpected drop to 200MHz that means the string locked up and reset, which took the chips back to default speed and cgminer started ramping it back up to your setpoint.

Thx for the explanation. I like these Terminus R808, I want to sell all my 2Pacs and buy these with the money! ![Wink](https://bitcointalk.org/Smileys/default/wink.gif)

How is the noise on the power supply fan? Its a server power supply so the fan can get rather noisy but its not going to as loud as say 10 Terminus miners running. How would I run multiple Terminus R808 using the one power supply? You would need a breakout board and 6pin to 6pin power cables. one 750 watt power supply would be enough to run around 10 - 11 Pods around 225Mhz (60 watts each)

Thanks for that and kind of figured that's what was going on. So far the 237.50 Mhz is very stable and produces 100-104Gh/s all day with a good power supply and doesn't get too hot. I've never seen 275Mhz on mine but don't need to either. ![Wink](https://bitcointalk.org/Smileys/default/wink.gif)

Quick comparison - Terminus R808 vs 2 Pac Sticks - Power usage.
It may be the power supplies I am using but the comparison is:
1 x Pod @ 237.50 Mhz - 58.6 Watts 100-104 Gh/s
4 x 2Pac @ 237.50 Mhz 74 Watts 98-106 Gh/s
I run 10 2Pacs but am thinking . . . . More Pods Please!

I bet if you only run 2 you'll get the full hashrate out of 'em. Could be a USB traffic limitation, same as several other people are running into.
Just a question I've been thinking about. Would increasing the suggest-diff setting alleviate some of the USB traffic limitations? I was just thinking, why does everyone it seems, that have posted so far, been running with really low diff? I generally run my 2pacs at 512 aiming for 2-3 Accepteds per minute, or am I doing it wrong.

Hi! is it to be expected that i wouldn't be able to 2 pods off of one regular power strip (rated at 10A as it says on the bottom)
i did some googling and 60w = 5 amps so that will be 10 amps already without the hub and the controller (laptop)
it will confirm how i am able to run them stable plugged in directly to the wall (separate) but not together on one strip
thanks!
