con,

i've pointed my avalons with your firmware at my server to solo mine.  will there be any performance issues that occur in that situation versus pool mining?
Provided you've set up pool software for your solo mining it's fine, however avalon+cgminer mining directly to bitcoind is a disaster.

any idea what's causing this?

i have successfully setup slush's stratum pool mining software on my linux server.

however, initially it was streaming thru pages of hashes w/o problem but now has slowed to a crawl.  some memory buffer or something must be filling up.  

i doubt, however, it has anything to do with cgminer/avalon.

i'm sure people will eventually need it when a fan or two goes out
My first goal was to install more powerful 252CFN fans as ambient temperatures now over +30c.
Also overclocked it to 360Mhz, hw errors near 1.6% 1.7%. Temperatures now like 32 / 48 with new fans even not running at full! To be exact, the model is TFC1212DE-SP07 and it's used in HP DL580 servers.

So I did a little experiment and partly covered the intake of fan3.
Result ? Better cooling and higher Mhz!
I also just covered fan hole and unplugged it to prevent air go back.

Firmware 20130702-1

Strange effect on a silver Avalon. I noticed that fan3 is running at 1200 rpm, while the others are well over 3000.
Frequency:299 Fan1:3360 fan2:3600 fan3:1200 temp1:30 temp2:-1 temp3:49

I guess fan3 is weaker than the other two.
So I did a little experiment and partly covered the intake of fan3.
Result ? Better cooling and higher Mhz!

Frequency:299 Fan1:3360 Fan2:3600 Fan3:2280 temp1:29 temp2:-1 temp3:47
and later:
Frequency:317 Fan1:3360 Fan2:3600 Fan3:2280 Temp1:29 Temp2:-1 Temp3:48

Ambient also went down 1 degree. Seems odd that partly blocking intake of Fan3 lowers the ambient temp.
Probably due to location of sensor.

Food for thought: Monitor fan speeds and maybe lower speed of fan1 & 2 when fan3 starts slowing down ?

How long do I have to wait till "avalon-auto" finds the optimal frequency? Or after what time I can say thats the optimal freq now to set locked?


It will usually continue to fluctuate indefinitely but you'll find it hovering +/-2 MHz, and that value's about the optimal. It will of course go lower if it starts getting too hot. Most seem to fall into two camps, close to 350 or close to 365. I run mine slightly lower than 350 since it seems to end up rebooting the router eventually at the highest setting (not cgminer but the whole hardware which is a little disconcerting). This is why I was experimenting with a less aggressive firmware yesterday, but in this world maximum hashrate seems to be the only thing that matters for most people...

does --avalon auto require that default be left at 282?

reason being, hashrate the other day wasn't going up as fast as i expected so i gave it a boost by changing default to 325 which obviously immediately jacked up the MH/s.  everything seems ok since but should i not have done that and is it affecting the auto function?
Nope. Whatever you want as starting speed.

I sure wish the Ztex boards had that option.  They seem to be hardcoded to start at 200Mhz.

To stay on topic, is there any possibility for changing the clockspeeds of the Avalon hashing modules (or to 10-chip submodules) individually?  Looking at the photos, I can see a separate crystal on each 10-chip submodule.

This is kinda strange. When I got my ASIC, it was hashing at 66 GH/s.. then.. I was able to constantly clock it... from 66 - 80 GH/s I'm afraid of 85 GH/s >_>

Would it be advisable to bring the PSU outside the box instead? It would seem to lower the temps.

Avalon previously recommended against this.  The PSU needs to be cooled as well.


I think it's better for the psu to suck in cool fresh air outside the box then warm/hot (40+) air inside.
My psu performs better and the hashing-modules are 2-3 degrees cooler. Temp3 dropped from 46 to 42-43.

But ambient temp overhere is ~20.

So, finally i build a functional firmware with my changes to cgminer in previous posts and a little backport from latest firmware. Currently using it, fan speed regulation works as expected. I guess, no one needs it now, but feel free to ask if you intending to replace fans to TFC1212DE or simular with inverted PWM behavior.

i don't need it but thank you Smiley

i'm sure people will eventually need it when a fan or two goes out and good to know there is already a fix when they post here freaking out 
what a weird issue

i've moved both my avalons to cons fw and the best surprise is that i've not had one shutdown or reboot.

to be fair 5/19 didn't either in the 3d that i've had them but i love the customization of cgminer.   its what i'm used to in the old gpu days.  Wink

I have a backup pool added, but there are three options (I'm working from memory so I could be slightly off):

  • Balance
  • Failover
  • Load Balance

I have slush set as the first pool and eligius as the 2nd pool and I selected FAILOVER (that was the default setting).   What do these options mean?  


I usually hate to give this type of answer, but give the cgminer README a quick glance, it's very detailed and well written.  For this you'd want to check out the MULTIPOOL section.

I didn't even think about looking for the readme file.  I was like a kid on christmas opening up the avalon and turning it on.  Once it started to hash I tiptoed away and refused to make any changes just in case i messed something up.  Whoever mined on my avalon before they shipped it to me had set up 3 pools with Failover so I assumed that failover was the way to go. 

Completely understandable, man!  I've just been using cgminer for a bit now and love how it works and how detailed the README is.  The devs are also available.

But I do understand about being super excited, if I don't get arrested for having a boner when the DHL person delivers my 4-module batch 3 avalon, I'm going to plug it in within seconds, not even inhaling any air until it's running (ok that might be a bad idea!).

i think it would be also useful to make AVALON_TEMP_HYSTERESIS constant as an option, will try to do that and test with AVALON_TEMP_HYSTERESIS = 1.

ADD:

tested today with AVALON_TEMP_HYSTERESIS = 1 , changed to AVALON_TEMP_HYSTERESIS = 2 , as this makes oscillations sometimes
(this is the first one i noticed today, but enough for me to increase this value)

Last 4 values in this log is a fan speed and temps:

failover moves from your first to your second if first fails, on down the line.

balance means hashrate is split evenly btwn listed pools.

load balance i don't have time to lookup.

might have missed a few nuances.


Wonderful, thank you very much.  I assumed that failover was as you described it, but I certainly wanted to be sure.  I appreciate your reply.
