Am I correct in assuming that ckolivas firmware is meant to replace the strombom and the official Avalon releases?
Is this really the best, most reliable measure? DiffA/time?
This gives me the best power to performance watts to accepted shares over time.
in the case of pool mining you get paid by accepted shares.

I've uploaded new firmware

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
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.
You don't. It is set automatically according to frequency by cgminer now.
Thanks. How do I control the timeout stuff?
I get way more rejects now but hashrate (MSHav) is up.
Firmware Comparison and Best Settings Results
Batch 1 Avalon with upgraded power supply Corsair AX860i
I wanted to conduct this test with 100% Fan settings. So I used the custom built firmware as a baseline prior to upgrading to the official Cgminer Avalon firmware release.
Below is screen shots of 1 hour for cgminer official release provided by ckolivas and 1 day unofficial firmware results. I compare both firmware types at 345, 350, and 355 speed settings.
You can calculate your own system performance by taking the total accepted shares and divide it by the total hours or total minutes.
Results after 1 hour at 100% fan, speed setting 345 running cgminer 3.3.1 official release with custom fan speed, temp cutoff, custom system speed options.
69696 Accepted shares 1 hour duration at speed setting 345 = 1161.6 accepted shares per minute.[/size]
cgminers official release 20130627 is the Best performance per watt.
Results for the unofficial release after 1 Day (24 hrs) at 100% fan, speed setting 345 and 355 running strombom firmware running the old cgminer 3.1.1 with the limited speed options and fan speed is always 100%.
1648544 Accepted shares 24 hour duration at speed setting 345 = 68689 accepted shares per hour or 1144.8 accepted shares per minute.
1702544 Accepted shares 24 hour duration at speed setting 355 = 70939 accepted shares per hour or 1182.3 accepted shares per minute.

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.
case 300:
buf[6] = 0x63;
buf[7] = 0x09;
break;
case 325:
buf[6] = 0x28;
buf[7] = 0x0a;

buf[7] = 0x0a;
break;
case 375:
buf[6] = 0xb8;
buf[7] = 0x0b;
break;
Does anybody knows ALL buff 6 & 7 numbers for all frequencies?

With pretty cool ambient temps also I guess your room temperature is about 15 Celsius?

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.

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