You need to be using GBT if you are solo mining on bitcoind. You can't mine via getwork on bitcoind at those speeds.
I do getwork solo with 60G, but it is 24 seperate miners, not one unit hitting all at once if that makes a difference?

Remains try it in a solo. This power is enough for the production of a block of time in 3 days, but that's not the case, and in the stability.
Already tried straight solo mining to bitcoind, as noted elsewhere. Saw at least 10% "get failure" rate, and it was falling back to the 2nd and 3rd pools.
It probably makes sense to set up a 1-person pool server, for solo mining, than go straight to bitcoind.
Make sure you are not mining at difficulty 1.0. diff-1 is the original difficulty for pools, and it generates too much network traffic for this ASIC miner, possibly leading to many restarts.
Find a pool with "variable difficulty" or "vardiff." p2pool supports a higher-than-1.0 difficulty by appending "+N" to the worker's name, e.g. "1BrufViLKnSWtuWGkryPsKsxonV2NQ7Tcj+8" for difficulty 8.0.
13 hours uptime and counting, since switching back to BTC Guild/stratum/vardiff.

ah, okay, that makes sense. i am used to ltcmine.ru that constantly adjusts based on your hash rate (not sure if pool.itzod.ru also does this).
hi jgarzik,
did you try http://hhtt.1209k.com/ ?
it is a variable diff pool with very low fees for high diff shares, but no stratum.

That pool is fixed difficulty share (32), vardiff adjusts the difficulty every x minutes for incoming shares based upon your hash rate.
hi tacotime,
no, 32 is default difficulty if you don't ask for a different one.
you use a bitcoin address as username and suffix it with desired difficulty, for example an address like 1....._512 asks for 512 difficulty shares.
_NNN is the difficulty you're asking, with 66 GH/s you can use 512 or 1024 without too much variance.

hi jgarzik,

it is a PPS variable diff pool with very low fees for high diff shares, but no stratum.

This is encouraging. Hopefully more units will roll in this week.
Good news. Mining on BTC Guild with vardiff seems to have dramatically reduced the restarts.
Which cgminer version are you using?
For stratum Im using the latest xiangfu openwrt solution with cgminer 2.10.4 running 27 icarus and my rig is constantly restarting,
before update was using cgminer 2.7.5(non stratum) and the 703n was more stable.
Avalon's cgminer 2.10.4, as described in the review linked in the OP: http://garzikrants.blogspot.com/2013/01/avalon-asic-miner-review.html

edit: Im read the review and confirmed it is the *same* version!
What changes did you make to reduce the restarts?
So who is Jeff Garzik and why does he get the red-carpet treatment? I must have missed that memo...
I may have missed it - has anyone but Jeff and the hand-delivered BF received their shipment?
Have any other Avalon user's checked in yet?
Network has rate is up 1.5Ths/s, yes I know that's an estimation.

Maybe it's just normal restart variance

Thanks for the update.

BFL's single uses 72W at the wall, there is no ATX psu or DC/DC or extra for fans etc, just the host usage to be added. All speculating of course coz it ain't alive yet, but it is definitely no 620W, or 108W.
Yes it's all speculation. At the moment BFL is paperware which uses no power at all and produces not a single hash. Let's wait if they manage to release an ASIC product at all and after that, let's see what their power and hashing values are. At the moment Josh started with his pre-delay anouncements so don't expect a release soon.
Back to Avalon, will they open the source code or at least provide the sources to their customers?
You probably know that your UPS can supply only 330W of load on its "battery backup" four outputs (the upper four ones). So maybe you connected Avalon on one of the four lower, "surge only protection" outputs.
He did originally, but not now:
Quote from: jgarzik link=http://garzikrants.blogspot.com/2013/01/avalon-asic-miner-review.html
After 30 minutes or so of mining, the lights in my room flickered, UPS's beeped and complained. Because of some stupidity (plugged into 'surge-only' side of UPS), the miner restarted as well. After some reconfiguration, this problem was solved.
since a an APC BackUPS ES-550 can only supply 330 watts (I have 2 and can can confirm that spec, its also posted online), plugging a 620 watt Avalon into the "surge only" outlet is correct - ie, use the unit only for surge suppression. if its plugged into the "battery backup" outlets the unit will likely just shut down when presented with that kind of load.
Aseras is right, get something more substantial. at the kind of coin that thing is cranking out right now its almost certainly worth it. needs 1100 VAC (650 watts) at least, so 1400 VAC (820 watt) unit is reasonable.
In my post I wanted to say something like "you probably connected into surge because backup output is not able to power it when power fails". If it's plugged into "battery backup" it will work fine until there's an outage or sag. In that moment the APC will shutdown its "backup" outputs and start to beep.
As you said, more substantial UPS is required.
Continuing to see restarts. Restarts result in resumed mining, in all but one case. In the "one case", the miner was accessible via web and cgminer was alive, but no work was being performed.
Yifu does not think heat is a factor, but speculates that other software components may be at fault.
Switched from slush to BTC Guild for the "vardiff" feature, to reduce network overhead. Eligius also just deployed the "vardiff" feature. This feature will be crucial for ASIC miners.
