Any update or responses to some of the posts and questions? A lot of us are watching this very closely, this is a race, and Steamboat seems to be winning.

Updated the website with our office address. Final moving in tomorrow. Anybody who wants to come visit can call us for an appointment.

We are still deciding whether to accept Paypal/CC/Bank Transfers.

The modular boards, even if ordered without a case, will come with heatsinks.

The DX Mini supports 20 K16s, not 10.

For those who won't use the search functionality.

Set the clock to 275 MHz, and now the board is hashing upto 3.96 GH/s. I waited quiet long to see it touch 4GH/s, but that never happened. WU is stable at around 60/m. HW is quiet low.

There is still room for improvements. Our board doesn't work at 300 MHz. I am going to try and fix it tomorrow. A lot of nonces are duplicate (extra work!). BkkCoins has given me a few leads, I am gonna work on them tomorrow as well. I am gonna hold back the video until we touch 4.5 GH/s!

Amir, thank you again for the update.

I know this has been ask and some have answered yes, But will the finished boards ship with a Heat Sink attached?....and then we just have to rig cooling fans etc. I wish we could get that clarification from Terrahash. Even though I know a few have said that they will...we just need to be positive on this. If I have missed something in this regard, please let me know

Nothing like turning on the lights to make the cockroaches scatter.

Here's to a hashing board almost to advertised specs and the return of the 3 figure BTC value.

TerraHash sample k16 board hashing at 3.6 GHash/s! Its clocked at just 256 MHz/s right now. Video coming in a short while.

Has anyone successfully changed their shipping address with TerraHash? They say they'll do it "in rare cases." I hope my case is rare enough; I found out after I placed my order that I'd be moving by the end of July. If I don't change my address, I won't receive my order, simple as that. I opened a support ticket a week ago, but haven't heard back.

Any ideas??

Incredible just one line of delay code and everything worked. Congratulations terrahash.

Eureka moment just in the nick of time as chips are about to ship next week

Good info, thanks for the update terrahash.

What's needed to cool the board at 275-300?

Yea I was having the exactly same issue. It has disappeared magically. Maybe the logging code I added, created a little delay and thats why the lock conflicts disappeared. Try adding some delay before wr_lock around line 1500 in usbutils.c

Code:

#define DEVLOCK(cgpu, _pth_state) do { \
			pthread_setcancelstate(PTHREAD_CANCEL_DISABLE, &_pth_state); \
			// add some delay here \
			wr_lock(cgpu->usbinfo.devlock); \
			} while (0)

I hardly get any good nonce if I clock it over 279. I have the exact same circuit as provided by BkkCoins. The only difference is that my capacitor is 33pF, instead of his 30pF.

I just changed the 220p capacitor to 30p and the circuit is also exactly the same as BBKCoins drew. Ktest still gives "GOOD" from 128M to 300M with correct return time.
However, cgminer's stuck more frequently. The WU at 128M goes down to 2.5/m, and WU at 256M goes down to 2/m.

~~It seems that this issue has a lot to do with the clock generation circuit. May be some results cannot be captured.~~

I will test your method.

UPDATE:

Your method works!!!

I added

nmsleep(100); \

and everything works like a charm.

128M ~ 8/m WU
256M ~ 17/m WU

BBKCoins, please be noticed. This might be a common issue.

*Chills.

Proud of BKKcoins, Terrahash, freeworm, and all of the open-source engineers that made this happen.
I applaud the awesome that is you.

Even I don't know exactly. I have had very little sleep in the last 3-4 days. I will look at everything again tomorrow and see what I changed that made this work.

Go get some rest.
Thanks for all your hard work!

Will do. Thanks MMNC. I'm glad the trip has helped everyone to rest easy. I'll definitely make another trip down there in the next week or two at the latest to follow up.
