So indeed the chips can do 450MHz

Using my numbers above:
(7.669 / 20) * 240 = 92GH/s at 400MHz

You increased the voltage in order to do that, right?

No I left it at the 1200mV default for the current run.

As you can see it reads 1223mV - but I'm not exactly sure how accurate that is.

Very nice Kano.

Any idea if this would be possible with batch 3 avalon hardware? With better cooling of course. Like 2x 120mm 6000rpm delta fans in the place of the stock 120mm fans in a batch 3 unit.

If you haven't already, you have to delete/remove WiFi, not just disable/stop it. Network->Wifi->Remove

I've deleted but after few hours of mining I see the error message again:

Code:

usb 1-1: clear tt 1 (8030) error -71
usb 1-1: clear tt 1 (8030) error -71
usb 1-1: clear tt 1 (8030) error -71

Unload the wifi kernel modules.

log into ssh and rmmod the following:

Code:

ath9k
ath9k_common
ath9k_hw
ath
mac80211
cfg80211

then cd into /etc/modules.d

and comment out, or if you're confident enough, delete the following files in that directory, to prevent them from being loaded on reboot:

Code:

20-cfg80211
21-mac80211
26-ath
27-ath9k-common
28-ath9k

Just a 'somewhat' on topic aside ...

I have a BitBurner XX with 20 Avalon chips in it.
It runs at 400Mhz with about 1.4% HW

Code:

BTB 0: 48/ 48C 1223mV | 10.86G/7.669Gh/s | A:149590 R:748 HW:2151 WU:108.6/m

24hrs runtime

I put it up to 450MHz and it was about 50% Tongue

but appropriate cooling would have probably resolved that also.

So indeed the chips can do 450MHz

Using my numbers above:
(7.669 / 20) * 240 = 92GH/s at 400MHz

i see some users running at 350mhz for batch 2?

is it possible to run at greater than 350mhz, at 360mh? for batch 1 with say 1250w 80+ gold psu?

previously it was running at 345mhz on a 1000w psu

so i got a new 1050w and was thinking if i should return and exchange it for a 1250w psu instead for greater hashing rate and make up the shortfall(downtime)

I am running batch 2 3 modual system with 860W Corsair AXi Series 80PLUS Platinum Modular Digital Power Supply am so far close to taking it to the mark of 400MHz per chip I have so far tested upto 360MHz rock solid and thinking to increase and temps at a good rate too then again I have also done air flow mods to it to improve channeling of airflow to the modules.

If you are on a 4x moudal I am unsure what to set too as I have seen a lot of people having problems taking above 340MHz due to amount of power it sucks up. I am running 3 at 360 to 365MHz and only taking 760 intake feed of power and using only 700 of it so this Platinum psu is very energy effective while temps never going over 50c Am also wondering if I can get to that target of 400MH/s per chip but even then that's pushing it way too much but will see as I have full monitor status of unit of how much each modual is sucking up and how much amps its using.

Quote from: BitSyncom on June 25, 2013, 12:11:37 AM

was wondering how long it'd take people to notice ( and more importantly share the constant that we've released on github.)

the number you are all aiming for is 450 Tongue

of course, that's not really possible on just air cooling.

That problem is described well. Wifi chip is taking too much power (maybe due to missing wifi antena).

I have had same problem and solved it by removing wifi interface and rebooting openwrt (wifi kernel module will be not loaded again).

Hey Avalon users!

I'm working on a Bytecoin ~~P2Pool~~, and now have a testing server with the updated ~~p2pool~~ which supposedly should support your Avalon machines!

I'd like to ask if anyone would be willing to help me test it? I understand Avalons had significant difficulties with the older versions of p2pool, and I would like to make sure it works as advertised before I switch my main pool node over.

If anyone is willing, please send me a PM

Thanks,
Digigami

UPDATE - Had someone volunteer.. and it appears the updated p2pool is still suffering issues at this time.. back to the drawing board

Thanks I'll give a try but after few hours of mining I also noticed that some of the match_work_counts are zero:

Code:

   [match_work_count9] => 0
   [match_work_count10] => 0
   [match_work_count11] => 0
   [match_work_count12] => 0
   [match_work_count13] => 0
   [match_work_count14] => 0
   [match_work_count15] => 0
   [match_work_count16] => 0

It looks like some of the chips are not working.
I rebooted the unit many times but the same match_work_counts are always zero.
The unit running stable but only with 50-57 Gh/s. Sad

What can I do?

Open the cover (count the nuts you retrieve so you don't end up with one dropped on the inside shorting out
the FPGA board) and re-connect the power cord coming from the PDU to the second hashing module and also check it's flat cable going to the FPGA controler board.

One of them is probably loose from shipping abuse

Thanks for your reply!
I've already done it.
I opened the box and found this:

One of the four hashing unit's molex connector wasn't connected properly and it was already burned.
I fixed it and now everything seems to be working fine. (my fingers crossed)

Connect an ethernet cable from your Avalon directly into a laptop/computer.

Manually configure your computer's IP address to 192.168.0.101

Open http://192.168.0.100 in a web browser

Make sure WR703N can access Internet, Configure WiFi: Network -> WIFI -> Scan(select your WIFI network) -> Join Network -> WPA passphrase -> Submit -> Save & Apply for connect to WIFI Internet

Setup your mining worker: Status -> Cgminer Configuration.

Restart the cgminer service: System -> Startup

Check your avalon status: Status -> Cgminer Status

Setup password using ssh (or through the web interface)

Obviously: Make sure you have set up and are running over LAN first.

Regardless, 3 out of 4 of my batch 3 units end up with <10Gh/s after 3-12hrs of mining, some more frequently than others.

Could this behavior be due to the new temperature throttling feature? I have the default temperature limits of 70C target and 90C cutoff, but I don't see the temps going over 70C.

I had the same problem on my batch 3's. I noticed the load average was really high whenever that happened, logged in via ssh, and saw cgminer was eating nearly 100% of the cpu.

I solved it by adding this to the end of /usr/bin/cgminer-monitor

A=`top -n1 |grep cgminer | cut -d'%' -f2 | head -n1`
sleep 2
B=`top -n1 |grep cgminer | cut -d'%' -f2 | head -n1`
sleep 2
C=`top -n1 |grep cgminer | cut -d'%' -f2 | head -n1`
if [ $A -gt 80 ] && [ $B -gt 80 ] && [ $C -gt 80 ]; then
# echo "All are greater than 80"
killall -s 9 cgminer
sleep 1
/etc/init.d/cgminer restart
exit 0;
fi

What that's doing is looking at the cpu usage of cgminer three times, a couple seconds apart, and if it's over 80% all three times then it's too high, so restart cgminer.

cgminer-monitor already runs every two minutes, so at worst I'm only giving up about 2 mins of hashing.

Sorry if this has already been discussed:

Should I be connecting the second EPS12V CPU connection on the PDU board? It seems to be working just fine with one, but I'm not interested in toasting anything!

And if I should connect it, can I just use an 8-pin PCI-e connection? I've got only one "CPU" connection on my PSU.

I connected *all* the power connectors on my b3's and they all work fine:
1 x 24-pin mobo connector
2 x EPS 12v
3 x PCI-E 8-pin

I looked around and didn't see any directions on the forums about which to connect, and Avalon shipped with no documentation, so I figured it's a power-hungry thing and why not just connect them all.

You cannot substitute the pci-e for the eps connector.

Bought a nice ANTEC 1200W PSU
that only comes with ONE (ONE!!!!) CPU cable.

Why-oh-why couldn't they just have used 4x PCIE?
