Yep, regular old USB risers with 24" blue USB cables. Here's a pic of this particular rig:

I'll go check out the actual version, but I believe they are either 006C or 007C ones.

The same on my B250 boards does nothing, gpu's still running 5 GT/s, so this could be good news for Z270 and perhaps H270 owners, the intel 300 series might do the same, maybe better pcie hub.

you can check with gpu-z wich gen is detected/running at.
It looks like that doesnt matter.. Don't care.

Code:

root@miner011:~# dmesg | grep pcieport                                                                                                     
[    0.674260] pcieport 0000:00:1c.6: hash matches

This is quite intresting, is this just with the regular x1 risers what version, and how long is the usb3 cable ?

Jep det er jeg..

Looks like you are extremely lucky and got the right combination motherboard and risers to do pcie 3.0, check this
dmesg | grep pcieport
It will report if there is any errors on your pcie bus, you could have errors that is corrected but once you meet one that cant be corrected it can crash.

It will look like this:
[556771.420395] pcieport 0000:00:1d.2: PCIe Bus Error: severity=Corrected, type=Physical Layer, id=00ea(Receiver ID)
[556771.420404] pcieport 0000:00:1d.2: device [8086:a29a] error status/mask=00000001/00002000
[556771.420410] pcieport 0000:00:1d.2: [ 0] Receiver Error (First)
[556801.961161] pcieport 0000:00:1d.2: AER: Corrected error received: id=00ea

I know on my win10 rigs I can use HWiNFO to see the speed. Is there a command line option under Ubuntu that will show me?

I would go check in your operating sysatem if they are really doing 3.0, because its highly unlikely that you get 3.0 with usb3 cable risers Wink

alll risers support 3.0 (x1). well if motherboard support only 2.0, than the riser will do 2.0 as well.

Holy shit that worked!

Above screenshot is from Asus PRIME Z270-A. I have 6 rigs with those mobos, so I'll switch the other 5 to gen3. Ditto on the my 2 MSI Z270-A PRO mobos. Should also work on my 2 X99 based rigs I suppose.

Once I get my Acorns, I'll drop them both in a 7x 1060 first, see how it does, then a 7x 1080Ti rig, to see which show the better increase in terms of $/day.

I realize 2 Acrons will run at 100% all the time on a 7x 1080Ti rig, but it should lift them all by an equal amount, and just partially offload the GPUs, right?

EDIT: In linux for example this command would show your negotiated pcie speeds.

And a screenshot from HIVE OS after running gen3 for the last 20 minutes with no issues:

I have 6 rigs with those mobos, so hopefully they will take to gen3 fine as well.

Its simple the usb3 cables dont have the quality to negotiate pcie 3.0, think about it usb3 cables are made for 8b/10b same as what pcie 2.0 run, but pcie 3.0 use 128b/130b.

Now there is faster standards like USB 3.1 Gen2 or USB 3.2 that do use 128b/130b but i would imagine that they also have much shorter cables, and its not cheap Cheesy

EDIT: Already at pcie 2.0 these usb risers suck, if you have problems with gpu fallen of the bus errors in your syslog, and your gpu's are not too much clocked, you can usualy fix it by forcing pcie 1.0, so the risers are iffy even for 2.0, you say they can 3.0 I say NO !

I agree with Seth Estrada, the "Nest" products sound REALLY cool. Easily plug in various Acorn units into a pcie 8x/16 x slot. even almost pushed me over my reluctance to spend alt coins at this point in time... still though.. rough time to be spending coins in this market

I am thinking a 2 acorn 215+ nest would be nice in some of my mobos.

I ordered 2 x 215+ and the 2 card nest. Should be fun to try out.

So some risers support pcie 3.0? Most of my recent risers are VER 008C, so maybe they do. When I initially setup my rigs, the guides all said to configure for pcie 1.0 or 2.0. I'll change the 7x 1060 rig with the Z270 mobo to gen3 and see what happens.

Also, I'm curious if the sqrl miner is free. I know it doesn't have a dev fee, which is nice.

Yes there is risers with pcie 3.0 but they use ribbon cables and is quite short, its not the usb3 cables you know from your regular pcie 2.0 risers.

Im only guessing here, but if sqrl miner is not free, I would asume that having a acorn would also give you a license for the miner.

$42 for shipping such a tiny thing? I've never paid so much for shipping not going to start now.

And why all the payment weirdness? crypto or ACH transfer only? Even in satoshi's white paper it is said that crytpo is not expected to eliminate fiat but compliment it.

I can buy all sorts of mining -crypto related- stuff with traditional payment methods. I hope this weirdness ends.

Just some feedback... I thought we were going to see a payment portal that accepted traditional payment methods.

It was in the faq or something, methods like PayPal don’t like crypto mining related transactions. Hence crypto or ACH.

Ebay don't care right? all sorts of crypto stuff on ebay. Oh, and I can use paypal for that. fees? charge 10% more, it's still a free listing. There would even be cheap USPS shipping options with that route.

But it's fine, seems like a limited sale anyways... starting small. I hope it continues to develop and I truly hope everyone benefits per Acorn's vision.

Can I get a quick answer on best acorn for mining kryptonite Heavy Or Eth with 2x 1060 SC cards? Was going to go with the CLE-101 but don't know if it can handle Kryptonite Heavy...
Thanks

1:2 would most likely be fine for your 1060 and 1070 rigs, and then you can use your x1 ports but you need pcie 3.0 risers, and a motherboard with intel 200+ chipset to get pcie 3.0 on the chipset.

But for your TI rigs you most likely need 1 acorn per gpu, so each gpu needs atleast a x2 3.0 or x4 2.0 pcie.
