What do you guys think and old B1 3 module Avalon is worth today in $ and BTC used, taking into account that Avalon has 4 module ones for 15BTC on their store site, and the difficulty is about to hit 310 million. Also the B1's usually only come with a 650W PSU so they can't do more than 72GH/s, what do you think?



Probs less than 1.25BTC as their new on Avalons site for 2.5BTC

I think you mean the modules have dropped to 2.5BTC on Avalon's site, I see now the 4 module has dropped to 12BTC.  

Any other suggestions?

well at the rate they  are dropping every 2 weeks you wont get much. You might as well keep it and  or flog it on ebay and buy more 60gh units at the lower prices and get a good little return if you know how to work the alt coin world Smiley

I am looking to offer someone some money or BTC's for his. Smiley

This is why I asked without getting into the specifics as that person could be a member on bitcointalk. LOL

IDE cables have some interconnect, so i think this replacement will not work but certainly you can have a try.

Some interconnect? What do you mean by this?

They are 40/80 ping across the two connections with no twisting.

IDE cables have a missing pin.

Pin 20 isn't missing it's just covered because it's not used by the IDE controller, plus they added another security feature to make sure you don't plug the cable in the wrong way. In my case I can get straight through 80pin cables that don't have pin 20 blocked.

Smiley


If it's covered it's missing because there's a pin hole missing (therefor missing a pin on the other side) where one should exist ... 80 pin cables are wrong as the IDC connectors used by Avalon are 40 pin ...

Did you even read what I said? (shrug)

I read what you said and shrugged.  You said a pin was covered.  ---1) It's a hole that's missing (more specifically, covered).  2) The pin is missing (literally, it's missing). ---
What you failed to understand is if the hole is covered then the pin is missing.  There's nothing covering that pin that doesn't exist.

What you said is the pin is covered.  There, actually, is no pin that is covered.  There's a pin hole that's covered and a pin that is missing on the opposite side for IDE cables and their associated connectors and headers versus the correct IDC cables and their associated connectors and headers.  Translation:  Kartaiv was right ...

Depending on the manufacture some cables are likely missing the pin, while others aren't and what the manufacture does it put a piece of plastic into the hole to cover it. How I know this is because in my 30+ years of working in IT I have managed to destroy a few IDE Ultra 133 cables in my time which allowed me to take a look at the connector from a manufacturing level, 95% of the time the pin was there and the cable was punched down. Yes you can show all the pictures you want and draw conclusions based on your assumptions but until you do the actual leg work you are still only assuming the actual pin behind the hole that is blocked isn't there. Smiley

And I never said the pin was missing, I just said it was covered, there is a big difference between missing and covered.

Update:

This gets back to what I was saying about pin 20 being covered, see the blue connector and the black one not missing a single pin? Only the beige connector which is used for the secondary hard drive is missing a pin, the cables I am looking at buying are ultra 133 Black to Blue no beige in between and pin 20 isn't blocked on either end of the connectors from the outside.

Ultra 133 cables purpose was to cut down on the cross talk, which is something possibly the Avalon could benefit from but I will have to test it. Smiley

What the difference between these sites?

If no fees was the way to go why do people continue to use fee sites, wouldn't they simply just stop using fee sites?

Thanks,

If you have issues with hardware error rate add some solder around the buffers.  That fixes the HW error rate which is *usually* related to the buffers on the individual hash boards.
There isn't buffers in original Avalon design. May you mean 74LVC2G34 on the signaling bus ? (Config_P/N ReportP/N)
But I never see bad solder on this parts.

Those.  There's 3 of them (U13, U14, and U15) per hash board.  My friend and I've seen hundreds (if not thousands) of them under a solder rework microscope.  They all looked good from almost every angle.  Touching them up all of them usually fixed a HW error problem (Once we narrowed it down to the right hash board).  I'm not going to guarantee that it will fix a HW error problem.  I'm just going to state that there's a good probability that it will fix a HW error problem.

Wanna fix my batch1 boards? Smiley

My batch2 hovers around 0.5x % while my batch1 starts out at 0.3% but I have caught it 5.x% Sad

avalon wifi works well ?. or is it better to use network with RJ45

to reduce the temperature I have to use wifi for 4 avalons

wifi works fine, on some units. It all depends on the flakey TP-LINK TL-WR703N you got

I have units that work fine with wifi, I have others that would not

If you need to spread out the units to reduce temperature, just buy or make a few long ethernet cables, much more reliable than wifi

If you have signal problems in your house the cheapest way to fix that is to buy open-mesh.com devices. They work great!! The other option if you are a good lier is to see if Cisco is still giving away their Meraki wifi access point and sign up for that, you will have to lie to get it. Either way these are two very good solutions and they are 100 times better than your mickey mouse home wireless routers and access points that you buy at the local electronics store.

With a mickey mouse access point in my den I can barely get any bandwidth to my living room, with my meraki in my den I get amazing bandwidth on all my devices in my living room and other places of my house too. At work we have several clients who don't have more than 20 people  at any one given time using the WiFi so we have set them up on the open-mesh system which works really well, some levels are below ground in older builds, no issues that we have tested with the open-mesh.

Sorry how does using WiFi reduce temperature on any avalon when the WiFi and the RJ45 connector are connected to the same board?

893  Bitcoin / Hardware / Avalon ribbon cable question on: October 18, 2013, 01:07:57 PM
Has anyone ever thought of or has tried to use a 80pin (IDE Ultra 133) cable as the a ribbon cable on the Avalon to see if it improves anything?

I need to replace one of my ribbon cables on my B2 as one of the clips broke, not only do I recall the 80pin cables being better than the 40pin but their connectors/clips are stronger too.

OK, at the risk of this being a trick question, I'm going to humiliate myself by saying "we display the value thus adding readability"?

Thx for advice. I reflow all my boards and have 1.6% HW at 430MHz.
But observe interesting thing, HW percentage are depends from length and quality ribbon cable. Maybe in conjunction with solder quality on buffers ?

If you think the HW errors has to do with the ribbon cable, have you tried replacing them with 80pin cables? Remember back in the old days when there was IDE which 40pin, you could get an 80pin cable (Ultra 100/133) that had a 40pin connector, maybe this would reduce the HW errors?

Also how are you determining the % HW at MHz?

Nope sorry for the confusion, I was just giving some details on my hardware setting, each Avalon is slightly different, I have also replaced the TIM with paste on each module to allow it to run cooler allowing me to run at 360 Mhz stable. From my testing the hashing indeed remains constant, however H/W increase over time e.g. over 48 hours without restart, after running for long periods I see 6 - 8% which is just wasted electricity, so a quick cgminer restart solves all this Smiley

My advice for your setup is to have cgminer restart every x amount of hours keeping H/W errors low, use whatever Mhz setting keeps your units hashing high as possible and stable. Hope this makes sense.

Sorry for budding in here, but are you saying the HW on the status page is the errors? And when you mention keeping it low, what's the magic number? Smiley

Thanks

Does anyone know where I can get an extra thermal sensor for my B1? I noticed in the B2 there are two thermal sensors connected to module one and module 3 (of course there is on on one of the boards making it 3 total), this might explain why the B1 shows -1 one Temp2 because it only comes with one, well two technically thermal sensors, one connected to module 1 and the other on one of the boards. I would like to know if anyone has attempted to get another thermal sensor for their B1?

Thanks,
