Title: [UPDATE]Batch 2 AVALON STOCK OVERCLOCK to 84 Gh/s @350MHZ[STABLE]
Post by: cryptograd on June 22, 2013, 08:59:33 PM
After trying several different methods this is the quickest and most efficient I've found.

*[UPDATE] 350Mhz found to run stable and consistent on STOCK Avalon

1) Download https://dl.dropboxusercontent.com/u/16881231/avalon_clone/firmware/openwrt-ar71xx-generic-tl-wr703n-v1-squashfs-factory_20130519b.bin

2) Flash this image onto your unit by accessing your unit @192.168.0.100 and going to System -> Backup / Flash Firmware

3) REBOOT UNIT(delete any custom scripts u might have prior)

4) Go to Status -> Cgminer Configuration and under "Chip Frequency" select 350, then SAVE & APPLY these changes

5) Configure your pool difficulty properly(@Slush's pool its 64)

6) HASH LIKE A BTCEAST

My unit is completely stock and never opened. I keep it in a temperature controlled room. This image will make fans run constantly at maximum.

WILL UPLOAD UPDATE IMAGE IN A FEW HOURS

my specs are:

fan1      fan2      fan3
2400     3840     3720

temp1      temp2       temp3
  24             38           43

Ebereon has confirmed that electrical consumption @350mhz is 720 Watts


I have my overclocked Avalon at Slush's pool for over 24 hours now. At these speeds I believe 10 rounds is about 8 hours of hashing. Also I've noticed that cooling plays a definite almost immediate factor.
 

HAPPY HASHING

This is a 325Mhz configuration

In order to achieve anything higher youd have to overclock to 350Mhz... and on  a STOCK avalon you risk several complications.

This is the only STABLE STOCK OVERCLOCK.

All others require a PSU upgrade, additional cooling, more thermal paste etc

Which files did you modify? I skimmed over the source a few days ago and looked at the timing/frequencies in a few of the packages. Was it just as simple as adding the option to the menu and having cgminer do the rest with the passed value?

Also mind posting a checksum?

I was just getting ready to start messing around with building new firmware, but you beat me to it. Thanks!

This is the simplest upgrade possible. The image self contains all modifications.

After running this at a properly configured pool I am realizing Bitcoin reward that equals out to a 88Gh/s payout(2.3 BTC in a 24 hr cycle)

My machine never idles, never stalls, no reboot so far. Perfect stable consitant flawless hashing

You want to keep things under 48 for optimum performance.

Over 50 your unit is considered to be overheating.

I don't see why not, but I know batch 1 has a slightly lower rated PSU and less thermal paste, as well as having tighter spaced modules which seems to increase heat concentration.

Seems like batch 2 was made for higher heat levels and better ventilation as well as more power consumption.


Modify at your own risk

What's the risk if temperature stays low?

If you push it too far in terms of Mhz, you may cause undervolting in other components, which may cause serious hardware failures.

So far i'm seeing a "Utility" higher than 17 with values of 350 Mhz. Anything higher than that brings up hardware errors and lowers utility.

Yesterday I tried making the change of the PSU (batch 1) for a Corsair TX850W and working properly. Then, I flash the Avalon with the indicated binary from here and I have it running at 325 Mhz, the only detail is that the fans are always at 100% but it's a minor detail, I prefer more noise to have problems in the chips.

One question: as some pictures I've seen, BitSyncom used thermal paste applied directly but does not make good contact between the surface of the board to the heatsink surface.

It will work better if you install a thermal pad (0.3 mm thick)?


Regards.

None!

Unless you are depending on ur stock fans to achieve this(you would blowout your stock PSU)
This modification provides stable power consumption from your stock equipment.

Ideally youd want to cool the room to 65F or liquid cool the unit

I temperature control the room to 70F to comfortably get a healthy 77Gh/s at the box. As mentioned before a good properly configured pool(https://mining.bitcoin.cz/) will increase your earnings in way that resembles hashing @88Gh/s

this

but this thread was initially about overclocking a STOCK Avalon to 325Mhz

350Mhz is not something I would do to a stock Avalon without direct liquid cooling

350mhz x 240chips = 84000ghs. One of your units is loosing 4000ghs from that. They have 650 psu? 350mhz requires a 750 I think

The units are pulling at the wall ( i have a power meter ) 2.25 kW. I will replace the batch 1 PSU with a 1000 W unit. that should fix the issue you mention.

I think a 750 or 850 will do the job unless you plan on upgrading to 4 modules later

Wattage / 3 * 4 is what u need fir 4 modules.

I would stop running your batch 1 with overclock until u uo grade though

I have been running for more than a month at 345-370MHz, it's still stable. When the chip hangs to overheating it seems to just stop and cool down, then you have to restart the unit...

I don't think there is any warranty to void in the first place :)

Is anyone able to compile a firmware where the fans still throttle, or a way to change that manually? I need to sleep next to this thing.

Also a way to set max temp to 48/49? One of the modules sits on 47 which triggers max RPMs, although I can hopefully move this to somewhere a bit cooler.

You first download the firmware onto your local system and then tell the browser to upload to the Avalon

For example you download the image from

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

and then you browse to

System -> Backup / Flash Firmware

Click on Browse, select the image you just downloaded from you Downloads an click on Flash Image

Then Ack the hash (if you want to check) and reflash the machine. Wait 3 minutes and log back in, running the new image.

By the way, are *you* the guy selling the ASIC managed hosting?

I'm offering to do managed hosting of 1 unit Avalon with 3 hashing units for EUR 100 / month in Belgium eh... never mind... why do I even bother to bring this up...

At least I've been reflashing embedded devices for the last 19 years.... it's really not that difficult if even I can pull it off...

Hello I have a question. Is their a way to bypass the TP-LINK TL-WR703N v1 and use your own router and then use cgminer to mine with. I have a friend who has a problem with his TP-LINK TL-WR703N v1 as it is not connecting up to his pc or laptp, however all lights are showing on including on the board for the tp link and lights on avalon shows solid green light and other light yellow stays on but cant connect up.

Any ideas how to bypass TP and use own router and cgminer and configure?

Yes, you can connect the USB cable from from the TP-LINK to a computer running cgminer but you need to tweak a jumper to prevent the port to provide 5V:

You have a friend who can't post to this forum? My doctor also gets questions about things friend of mine contracted in a back alley... is the same case? ;-)

https://www.youtube.com/watch?v=OZHAiTl81tA

Anyways, there have been a few people running their own version of cgminer on an i386 and connect over USB to the avalon modules

https://bitcointalk.org/index.php?topic=150482.msg1606249#msg1606249

But it surprises me he can't get the TP-LINK to work, they all get tested over wifi at the assembly plant.
Are you sure his ethernet setup is correct?

You have a friend who can't post to this forum? My doctor also gets questions about things friend of mine contracted in a back alley... is the same case? ;-)

Anyways, there have been a few people running their own version of cgminer on an i386 and connect over USB to the avalon modules

https://bitcointalk.org/index.php?topic=150482.msg1606249#msg1606249

But it surprises me he can't get the TP-LINK to work, they all get tested over wifi at the assembly plant.
Are you sure his ethernet setup is correct?



I havg oen through a call with him and he has tried everything possible and is getting no where with it. I will contact him when he is around and see if can get the above to work

Hello I have a question. Is their a way to bypass the TP-LINK TL-WR703N v1 and use your own router and then use cgminer to mine with.

Yes, you can connect the USB cable from from the TP-LINK to a computer running cgminer but you need to tweak a jumper to prevent the port to provide 5V:

I'm the fella who can't get his ethernet card to work on his avalon.  I've tried multiple computers and used network switches and nothing.  Not a damn thing.  So I guess i'll get a linux box going to get this thing started and wait for ebay to deliver me a new WR703N router eh.
Like the vid by the way lol


Edit: Update, as I was doing an OpenWrt Failsafe which worked fine, I noticed i had to jam my ethernet cord unusually hard into the tp-link router.  Upon inspection of the router one of the ethernet pins was bent out of shape.  Go figure some tester bent the crap out of it.  Works fine now. thx everyone for the help

I am doing this upgrade and I will report back.  I also have been playing with other modifications and they have been doing well.

UPDATE

345mhz is best with this build. STABLE, fans on 100%, low hardware errors. 82 - 84 Gh/s
700 watts

Unit can run unaffected at temps up to 55C like this. Which means ANY and ALL can benefit from this post. No extra cooling measures necessary.

My final comment on this.

Does this image set the fans to 100% or do I need to do that myself?   If so, how to I manually set the fans to 100 without bypassing them connecting to the board?  Thanks

FWIW - Often 100% fan speed gets you only marginal improvement over say, 80% fan speed, but significantly decreases the lifespan of the fan.

Not a big deal if you can replace them (and the unit automatically shuts off to prevent overheating) though

I got a peak of 94Gh/s.... is that safe? I got it @ 300Mhz with autoclock, but my average is around 80Gh/s

right now the noise is pretty high.


Are my fans and temperature safe?

Fan 1 = 2760
Fan 2 = 3480
Fan 3 = 3480
Temp 1 = 25
Temp 2 = 45
Temp 3= 48

thanks!
B.

Those temps look good.  Don't let them go much higher though.    These fans are made to run under full load.   It will just be loud.   I updated mine and they are all running 80~ +.

There really isn't much harm running them hotter - these chips are spec'ed and tested up to 70C, even then its really unlikely the lifetime of the chips would be < useful lifetime... AND 1 chip death doesn't matter in this design.

I'm getting similar temperatures at similar fan speeds but with a 33C ambient [yeah, fml].

yes you are cooling efficiently.

what build is this that you are running?

Alsobyou should only consider the top MHSav number when declaring your Gh/s rate.

not true

inappropriate cooling will lead to higher hardware failures... thus more restarts and down time.

Inappropriate cooling is putting the garden hose on it. Higher airflow is not going to damage anything.

I set mine to 350 and it seems to be stable. Temps are 11,35,35. It's got cold air blowing on it though. Definitely not crashing like my Butterfly units do, I have to turn them back on at least once a day.
