Or even better, direct X percent of mining or X many chips toward Y pools. I'd LOVE that.
I can't fathom how this level of control serves any useful purpose.

 I like to mine more than BTC.

I cold split up various accounts on PPS pools, PPLNS, etc... for alts, and for BTC. Serves infinite purpose for me. I can divide my hash at desired percents, etc...

Where you located? So, what do you think 1.3v @ chips would yeild, at least 400?
Also, I have upgraded the fans in the unit to 2x 5k RPM 250cfm .. Currently the avy temps read maybe 45C during day time and 35C @ night.... I know this is cooler than the chips themselves but much better than stock cooling. Do you think that would cut it?

Just did quick test of 375mhz ... stable but 6.5% HW error ... think just doin wire mod will bring that down to 2%? =)

Im in Texas.   1.3v should have no problem with 400.   Im only at 1.336 and getting 460mhz. 

As for cooling:  If you do good thermal paste on the backside and are in a cool environment you may get away with just air cooling.

Sure can.

Hi, if you have time, would 350-400 or even 350-450 be an ok autosetting in a 20dgr airconditioned room? for an avalon batch 2 3 module unit.
Unless you have done hardware modifications, you will not find any stock avalon under any conditions that will run much better than 360. The firmware posted so far already allows for speeds up to 450.

What kind of hash rates are people getting on Batch 2s with 450 freq?? Sounds nice..

Is there a way to set a 4th pool in the web interface?

You might use the more option field for this, just append 4th pool setting to your avalon options, such as

Quote
--real-quiet --avalon-auto -o stratum+tcp://stratum.btcguild.com:3333 -O ur_worker_name:123456

Didn't tried it, but it should work.  Why do you need 4th pool?

Honestly, I wish we coudl have as many pools as we wanted for the Balance feature. Or even better, direct X percent of mining or X many chips toward Y pools. I'd LOVE that.

have any idea what thats good to or is there no spec for that?
Also, feel like doin this to anyone elses avy? =P

Id have to look up the spec on the inductor.

I would be willing to do the electrical stuff for a BTC or 2.  

The watercooling stuff you are on your own.  TIG welding the shitty extruded aluminum is a pain in the ass!  

But then again if you want this done bad enough I suppose Id do it all for a price...  Make me an offer I cant refuse  Smiley

I suppose Id sell my unit for the right price as well.   140ghs fastest Avalon on the planet Smiley

What's the highest recorded sustained without any crazy cooling for a Batch 2 Avalon, does anyone know?

Yea Im impressed with the VRs on this thing!!!  Im running 1.336v measured under load.   The sense resistor is set to 1.43v

Im going to have to hook up a 2nd 12v supply!

I wonder what the Power distribution board in the Avalon can handle??!??!

So, if you had to guess, what would be the most limiting piece on the VRM section before something burns out...

Assuming you keep things cool...  Inductor reaching its saturation point would bring the party to an end.

OK... Just hooked my Watt Meter to to the 460Mhz overclocked 2 module unit and it is pulling 855watt at the wall!!!

 Shocked Shocked Shocked Shocked Shocked Shocked Shocked Shocked Shocked Shocked Shocked Shocked Shocked

I only have a 1200 watt power supply!!!  I will have to add a 2nd power supply or downclock when I add the 2nd two modules!


HOLY SHIT BALLZ! ROFL 2 modules pulling that much! DAMN! Each miner pulling around 50watts! What voltage? 1.4-1.45v?
Thats around 35amps through each VRM...Im surprised it can handle that!

You cant software set avalons voltage... they have to be hardmodded for voltage...
How hardmodded?

here is a bit of what i have done.  I will do a full writeup once i get everything put together.

Very impressive skill set there S M I L Y. Looking forward to more pics of the heat sink mod.

Right so...

Like I implied a few quotes back. See what it gets to with with just those settings.




PMed you.  Lets take this offline till things get working.

Thanks again!
Sorted offline, running stable at 461MHz with temporary firmware reuploaded.
--avalon-options 115200:32:10:35:400 --bitburner-voltage 1220 --avalon-temp 70

avalon batch 3 Use this command correct?
--bitburner-voltage or --avalon-voltage?
Extremely grateful!

YO DUDE! Congrats on the successful OC... hows the avy miners dealing w/ the power increase? The VRM still doin good? How much power is the unit using?
Wish I had the ballz to do this mod...lol ur at 108GH w/ 3 modules now, thats awesome!
