Who likes pod miners?

[NotFuzzyWarm]

I'll see about grabbing it and putting it on my Imgur act. The direct search link was several lines long
Here ya go: The Single

I need the pod! What's the latest ETA?

[isoneguy]

Try reading his threads....
The 1384 is the last chip from Bitmain that can easily salvaged and reused! All others after it are damn near impossible to work with due to the smaller pitch and issues on removing the heatsink adhesive.

Have you tried using rubbing alcohol to remove the adhesive? ..You just apply a bit and heh...Rub whatever is on there off. That's what we used at Nvidia to clean chips.

[sidehack]

The black epoxy won't come off under rubbing alcohol or acetone. The white epoxy is acetone-soluble. I don't know of any epoxy that'll dissolve in rubbing alcohol, nor would I respect it if it did. But that's not really the point, or at least not the entire point.

As has been mentioned a lot of times before, having to heat 50-60 individual heatsinks and pop them off and then pop all the backside heatsinks off and then soak the board in an industrial solvent and scrub off epoxy just to get the boards to a state S5 boards are already, and then you have to strip the chips and then reliably install them on something being careful around the 0.4mm-pitch pads and traces, really REALLY isn't worth the trouble. Don't even argue. It's not going to happen. I already put up more effort than most sane people would to get BM1384 products out there using stripped chips.

So anything newer than BM1384, I'm working on BF16 dev for that because I can actually get new chips instead of wasting buttloads of time jacking around with someone else's crap trying to harvest chips out of a hairball of metal and glue.

Were you cleaning an actual thermal adhesive, or just regular heatsink grease?

Were you cleaning an actual thermal adhesive, or just regular heatsink grease?

Used it for everything...High percent...Not sure the exact brand or solvent... isopropyl maybe or peroxide?.. Something flammable, we needed chemical clearance to use it..
But that's just business politics.

Gasoline might also work... Heh, just being creative

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.

they will be nice items when they release to the public.

Good news. Can't wait for it!

Nice hopefully you can use the same pcb to run the 16nm chips can't wait for that..

[sidehack]

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

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

[xxooss]

Count me in!

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.

[sidehack]

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

[NotFuzzyWarm]

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?

[sidehack]

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.

[NotFuzzyWarm]

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

[sidehack]

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.

[xxooss]

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

[Morguk]

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