[RUN 2 CLOSED][SIDEHACK STICK]GekkoScience Compac Official sales thread

[sobe-it]

So each stick runs are 8GH/s, but can be overclocked to 23 Gh/s?

To get to 23Gh/s or over you need a fan pointed at it or upgrade the heat sink. I took an old bfl heat sink and mounted it with the fan. It never thought about getting hot, if I turned off the fan the heat sink would be very slightly warm to the touch after a few hours.

Got more sticks hitting the post office. I'll have tracking numbers sometime tomorrow.

Pulled-chip sticks start with serial number 2200. So if you get a stick with serial number less than 2200 (in this batch, 2001-2138) are the last of my new ASICs and 2200 on are the pulled chips.

Don't mean to pry or imply that I am impatient, more curious than anything, how many have been shipped?

SECOND RUN QUEUE: 597 sticks paid (156 shipped)

Sales for the second run of Compacs is now open. I will be assembling using pulled chips, but every Compac will still have the same testing requirements and warranty. Delivery should start in the middle of February. Total batch size about 750 sticks.

This is taken from the first post, which is continuously updated when more sticks are sold or shipped. I'll have probably at least 90 more going out Friday; the next order after that is 100 so it kinda holds up the line.

Sorry I definitely need to learn to read. Thanks for the quick reply.

My pair showed up today!

Thanks sidehack

I have three total sticks (nothing compared to some of you!!) but after minor voltage tweaking I have the following after ~15 hours.

 0: COMPAC 10002125: 300MHz                  | 18.29G / 16.44Gh/s WU:229.5/m
 1: COMPAC 10000268: 300MHz                  | 21.53G / 16.36Gh/s WU:228.3/m
 2: COMPAC 10002121: 300MHz                  | 15.83G / 16.47Gh/s WU:229.8/m

I still see a handful of hardware errors so I have to tweak just a bit more.  These three sit on a 7-port superpbag and there's a simple antec fan pointed at them.  I'll probably bump the frequency up once these are settled and seem solid.

I have 53 coming.. if I get that high.. would be wonderful.    500w 90A  mean well 5v hooked and ready to my 49 port hub.. can't wait.

[sidehack]

You won't get them that high on your 49-port hub. If you run all 53 evenly split across 3 hubs (and therefore 3 separate USB connections) you can probably do it.

I won't try to hit them that high  at least  1.5a per .  see what cgminer does with them default.

I think this is at least the third time you've been told this, but with your 49-port hub the limitation won't be power. The limitation will be USB's packet throughput limit, which will cap your total hashrate to about 300GH per connection (which is to say, per hub) due to not being able to keep them provided with work.

I have hubs that I can split the miners.. I just want to test both devices I have raspberry pi and the  Udoo quad.. I want to see how fast the system works.. when I run  Cgminer with Udoo it is much faster, more responsive then the pi.   the pi seems slow motion compared to UDOO.   that might play a factor also.  Since the UDoo runs Ubuntu 14.04.

Not sure what you are talking about re more responsive-probably how interface "feels", right?
Yes, pi B+ and pi zero are slower than pi 2 rev B, but it has absolutely NO influence on hashing speed whatsoever (I checked).
Also, having usb 3 vs usb 2 hub also has no effect, apart from most usb 2 having low amperage per slot, but there are exceptions.

My  eyeboot  49 hub can do  1.5a per port.

Pray tell us that the shipment is out today.   I need my miners.

I understand the difference in power but a USB 3.0 connection also allows for max throughput of 5 Gbps compared to 480 Mbps on a USB 2.0 connection. If throughput is a problem then upgrading to USB 3.0 would certainly help. The question is does anybody make a 49 port USB 3.0 hub?

[sidehack]

According to Novak's best guess, the problem was that USB2 was limited to 1000 packets per second regardless of size. Not sure if USB3 has the same problem.

According to Novak's best guess, the problem was that USB2 was limited to 1000 packets per second regardless of size. Not sure if USB3 has the same problem.

Well that's interesting, and does make some sense because USB uses what they call a "fixed frame structure" meaning each packet of information is predetermined in size, regardless of the information being transmitted. Unless there is a way to actually combine packets to make use of any unused space, it would not be possible to go over this limit.

Regarding USB 3.0 I don't really know if the frame structure was changed, however I do know that USB 3.0 is Full duplex whereas USB 2.0 is not. So theoretically this means on a USB 3.0 hub, work could be provided to the miners at the same time work is being submitted to the pool. On a USB 2.0 hub information has to take turns because its only half duplex. I would imagine this should improve the performance...but how much? I have no idea.

Why have you not upgraded the usb2.0 to USB3.0?     make it 49 hub 3.0

Data packets are the same for USB2 and USB3

Well, looks like someone done bought up the rest of the batch. Sales are closed.

Someone bought up the rest 200 sticks!!!. I am not fast enough to order this batch.
Do you have a plan to run third batch for sale? I think there are still many people that want to try this stick.
