The new Terminus is definitely better, but I'm still having issues at higher power levels. My test board is sitting comfy at 150MHz (66GH) 26W including fans but it doesn't like pushing higher than that without locking up the string - usually that means voltage sag. Hopefully it's something that can be ironed out without another PCB redesign.

I would not mind  point them at a few pools.

mmpool.org  for one.

That regulator is the one that's being replaced on the new version. VH and I both have hacked-up boards with external main regulators spliced onto them so we could experiment with drivers and such at full hashrate because the onboard was by no means robust.

You did notice that's the "instantaneous hashrate", not the steady-state, right? At 325MHz the average hashrate is 143GH. If you can push one to 450MHz without it melting down (might be possible with "pencil mod" to the main regulator since the required voltage is out of range) it'd hit 200GH but it'd be pretty smokin' at that speed. Like over 100 watts kind of smokin'.

don't spill ALL the beans, please...BTW, where is that regulator [on the pic], incidentally?  Grin

It should be able to run 100GH without a fan, off a 12V 3A brick. It'll sure be toasty. The release version will have an overtemp shutoff set to 80C with a temp sensor in the middle of the chip field right under the heatsink.

Haha no I didn't notice that. I'm happy with anything >100GH TBH, but 150GH would be great.

Very nice to see the terminus can hit 200GH! How high can it go until it needs a fan?

very nice vh!  Is that a new version of cgminer? I cant get the one on the gekko front page  to work.

Jeez, 250GH would be almost 500MHz. That'd be smokin' hot. S1 hashrate is GH/s = MHz*0.512 (64 chips, 8 cores per chip).

But yeah, Terminus is basically an undervolted S5 chunk. Way better chips than the S1 had. Hopefully this week I'll have time to work on Bitfury dev some more because the BF Terminus will be able to put up almost 400GH at the top-end when it exists someday.

By Jove yer right. Just looked at the s1 manual. Top they show is 250GHs, lowest is 150 so the uc had to have been at the low end. No matter what, Terminus smokes them Smiley

You uh, you sure about that? Top overclock for an S1 was about 205GH. A good undervolt would see something like 140GH from 170 watts or so. The Terminus here is probably drawing around 65 watts, so about one third.

Or did you mean 175-225MHz, which would yield 90-115GH/s? Around there, a good undervolt for S1 would see something like 100-130W I would guess (it's been about two years since I did an extensive study on S1 undervolting) and at those hashrates the Terminus would see more like 35-40 watts.

Sweet. Terminus full tilt is about the speed I think was running my s1's at the end of their lives, they were down clocked to 175-225GHs. Bet it takes what, 1/4 the power?

Nice. For the 2Pac and Terminus, that's higher frequency than I've ever run.

Here's a cgminer preview of the three models running happily together.




And a view of them sprinting along the upper end of their voltage and frequency, with a firm amount of power and air to keep them going.

Just got shipping notification for the revised Terminus PCBs, only a few days after I expected to already have them in hand. So not too bad. Hopefully they're delivered by week's end and, double hopefully, the new regulator design works as expected.

That's great news. Please keep the updates coming!

No, that will not be possible for a whole lot of reasons.
