Did you power off/on the maschine? Try another Browser? Turn off antivirus/firewall for this moment?

Yup I tried everything... even modified the upload time-out settings in Firefox.

I think it's possible to start an update script from within the shell.
But if not I will make a direct connection with a laptop orso.

Can someone post the donation settings for ckolivas ?

Is there a way to update the firmware from the shell ?

I can't update from the web interface because it gives me a time-out error.

I had one of them a bit farther away from the router and the upload took much longer till it timed out on the first couple of tries.
Either make sure the connection is fine or just do it by connecting it directly to another computer with an ethernet cable.

I use chrome and works without problems.

Sry I can't help with shell update.

Do I stack these with the warm, screw-studded side down or up?

So I thought I'd make it easy for everyone to try the latest cgminer 3.3.0 and overclock settings all rolled into one, so here is a firmware with the overclock settings settable from the web interface:

http://ck.kolivas.org/apps/cgminer/avalon/20130624/openwrt-ar71xx-generic-tl-wr703n-v1-squashfs-factory.bin

Note that I have donation settings in the configuration so if you do not use your own config settings, it will start mining for me until you change them.

Usual warnings apply with aggressive overclocking: do so at your own risk!

Enjoy Wink

Thank you ckolivas!

If you could add the 5Mhz steps from strombom into your firmware and the ability to change it via web interface, I will send you a tip of 0.5BTC Wink

I am inspecting the info provided from strombom

There are difference between registers

Form latest con cgminer source

switch (frequency) {
case 256:
buf[6] = 0x03;
buf[7] = 0x08;
break;
default:
case 270:
buf[6] = 0x73;
buf[7] = 0x08;
break;
case 282:
buf[6] = 0xd3;
buf[7] = 0x08;
break;
case 300:
buf[6] = 0x63;
buf[7] = 0x09;
break;
case 325:
buf[6] = 0x28;
buf[7] = 0x0a;
break;
case 350:
buf[6] = 0xf0;
buf[7] = 0x0a;
break;
case 375:
buf[6] = 0xb8;
buf[7] = 0x0b;
break;
}

Form hacked cgminer 5 Mhz steps

   } else if (frequency == 325) {
   buf[6] = 0x2b;
   buf[7] = 0x0a;

} else if (frequency == 350) {
   buf[6] = 0xf3;
   buf[7] = 0x0a;

   } else if (frequency == 375) {
   buf[6] = 0xbb;
   buf[7] = 0x0b;

I will not patch mine cgminer unless con decides to implement it

PS: Att to strombom

Can you comment why values are different and timing also?

Thank you!

Someone asked me to provide a patch, unfortunately I don't know how git works but here are some of the files I have modified in my firmware:

https://dl.dropboxusercontent.com/u/16881231/avalon_clone/firmware/cgminer-3.1.1.tar.bz2
https://dl.dropboxusercontent.com/u/16881231/avalon_clone/firmware/luci-cgminer.zip

Tell me if any more files are needed, I don't remember which I modified... >_<

Here is a python script I used to generate PLL config (warning ugly code):
http://pastebin.com/3h7XGzTz

line 108 has some info about the overclock delay times, I had only guessed so my firmware should be modified to those values:
https://github.com/BitSyncom/cgminer/blob/master/ASIC-README

Thank You! I was the one to ask

I finally got it!

Do I have to open it up to change the PSU voltage settings so that it's 220?

Nope, that wont be necessary. But do open it up and check for loose screws, cables ,etc.

Thanks.

I've added custom temperature control to the avalon code in the cgminer git master.

It now acts like a simple PID controller trying to maintain a target temperature, which by default is set to 45 degrees, so it will try to keep the temp 43~45, but never going below a minimum fanspeed of 20% as a safety precaution and to maintain airflow.

You can modify this value with the new command:

--avalon-temp

Setting this to something very low will have the same effect as turning the fans up to maximum and vice versa.

If you are not running it from a command line, it can be added to the "More options" box in the web interface (once you have the binary on your machine).

Con,

--avalon-temp is a great feature. Can you be so kind and implement --avalon-cutoff-temp - Gpu style to put avalon in IDLE. I personally run my unit at home with air condition. Outside temp is 40+ Celsius. And i am away most of the time. So if the air conditioner malfunctions you know what will happen

. My home get even fired because of it.

It will be very useful feature for most of us

Thank you very much in advance!

The power consumption depends a lot on ambient temperature. My stock PSU consumes 850W at night and 950W during the day.
Upgraded to the Seasonic X-650 Gold 750W, and day power consumption reduced to 870W. All at 350MHz.

http://www.newegg.com/Product/Product.aspx?Item=N82E16817151087

850 W sounds like a lot for 3 hashing modules @ 350 MHz. This is at 120 V?

I am at 230 V and my default Batch #2 units with the 850 W power supply (enermax) pulls 765 W and the units I converted to a SilverStone Technology Strider Gold ST1200-G run at 735 W (92% power factor)

yes, 120V. There is a chance that my P3killawatt is off. I will verify with my FLUKE DMM.

I upgraded the power supply to a Corsair AX850 and now at 350MHz I'm pulling about 720 watts from the wall. The stock power supply is an Enermax 750 watt gold power supply, but it looks like it can't run very efficiently near it's maximum load and is probably very unstable given the number of hardware errors I was seeing with it at 325 MHz.

The Season X-650 is a 650watt power supply, so you may be overloading it and that's why you're seeing 870watts.

mistyped 650, actually it's 750W PSU

Seasonics are pretty good power supplies - I would think it would be able to run at 720 watts without any difficulties. I'm pretty sure my Corsair AX850 is actually a rebranded Seasonic.

Are you getting a lot of HW errors and rejected shares? If not, then I guess it's nothing to worry about.

Any improvements?

Yes, with the stock 750 watt Enermax, I was pulling about 890 watts from the wall at only 325 MHz and about a third of the shares being submitted were rejected. Now with the Corsair, I'm at 350 MHz, only 720 watts and an acceptable number of rejects and HW errors.
