I've uploaded new firmware

~~http://ck.kolivas.org/apps/cgminer/avalon/20130626-1/openwrt-ar71xx-generic-tl-wr703n-v1-squashfs-factory.bin~~

This one includes a minor calculation bug fix internally, and I changed the web UI to allow you to discretely set any frequency you like instead of the drop-down box, changing the default from 282 to 300 since I don't think anyone runs these at 282 any more. This will allow you to manually fine tune it yourself, should you find a sweet spot for your hardware.

New binary which really does what that one was supposed to:

http://ck.kolivas.org/apps/cgminer/avalon/20130627/openwrt-ar71xx-generic-tl-wr703n-v1-squashfs-factory.bin

I tested it with non standard values. It has sanity checking to prevent values <256 and >450 (hah!), but the usual warnings apply Wink

It also has the more relaxed timeouts which some people found allowed them to go to higher frequencies. See how you go, and watch for higher rejects than normal as a sign the timeout is too long.

Thanks. How do I control the timeout stuff?

I get way more rejects now but hashrate (MSHav) is up.

thinking of upgrading my PSU. just want to verify that 1000W will be enough to power 4 modules? (assuming that either Avalon will start selling upgrade modules or clones will become available eventually)

Also, I'm looking at getting seasonic 1050XM -- anyone have any real-life experience or opinions of this PSU?

These features are a huge bonus to all Avalon owners.

Doing final testing and will post results for unit #114 later tomorrow.

I will be sending you a few appreciation mBTC's

Thanks again.

thanks, con.

the latest firmware seems to fix the hashrate disparity between Avalon's console and pool stats...at least for me anyway.

I now have the highest hashrate I've ever had on a stock batch 2 at 83.7GH so far (but it's been only 20 mins so that might be just luck). EDIT: it was just luck, but it's still never been higher.

Doesn't seem to start mining if I input a non-standard number. I removed the --auto option and changed to 358 and 345 on two different miners and they never began hashing.
Switching back to 350 (with or without auto) makes them start immediately again.

Doh, forgot to update part of my build process. Will build another firm shortly, sorry.

      case 300:
         buf[6] = 0x63;

      case 350:
         buf[6] = 0xf0;
         buf[7] = 0x0a;

         buf[6] = 0xb8;
         buf[7] = 0x0b;
         break;

Does anybody knows ALL buff 6 & 7 numbers for all frequencies?

With pretty cool ambient temps also Wink

I guess your room temperature is about 15 Celsius?

I wish, no it's the basement but it's 20+ (~~near Temp2~~) (sorry, near Temp1...duh..)

Just noticed one of the three fans stopped working on my avalon. Opened up the case and found that the wire wiggled itself loose. Keep an eye on your fans.

ckolivas -

Do you think generated heat or the power capacity of all the other chips is causing instability on these overclocked machines?

My guess is not enough voltage since no amount of cooling can get them much higher than 350 reliably.

Something is wrong.
Cgminer says 80 GH/s advantage but Slushs pool only 70 GH/s...

Pools are just estimates. As long as the shares match on cgminer and pool everything is okay

take a look in the rejects in cgminer Status

3.1.1 crashed after about 5 hours running very constantly @325MHz
will now give 350 @ try
