Not sure if my math is completely accurate but let's say you have a Jupiter hashing at 500GH/s.  You spend an hour one day trying to get a few more GH out of it.  It's like you were hashing at ~480GH/s for that 24 hour period because of the downtime.  And if you do this multiple times every week, just how much are you actually benefiting in the end?  It seems like a lot of people are wasting valuable hashing time putzing around (as difficulty skyrockets) when they'd be better off just letting the damn things mine at a slightly lower speed.

Just sayin'.

What are these VRM's I've seen the last 10 pages? Are these those rectangle looking metal blocks on each ASIC modules? Each with a small white piece of tape/sticker on them? According to my thermal temp my warmest one is 90F. Maybe sticking a piece of thermal tape on top would help it out, no?

Like stuff like this?

Does anyone know how to turn off individual cores manually and keep them off? I'm running 0.97 and keep seeing a bunch of the same cores (2-119;2-126;etc.) getting disabled because of HW errors and then turned back on later. I think it's better to leave them turned off because they only produce HW errors and I don't think that's very productive. I have more cores running now on 0.97 but also have more HW errors, and in the end my pool hashrate is lower on average because of this.

I think .95 may do this automatically. On .95 my hardware errors over a 24 hour period start at 12 and drop to 3-4% according to bertMod on .97 my hardware errors were still at 12%.

.97 24 hour pool hashrate of 507 cgminer 535
.95 24 hour pool hashrate of 547 cgminer 552

I think .95 has some logic that gets better at using the cores, it really gets better over the 24 hour period, the hashrate slowly climbs.

Damn, dude, who pissed in your wheaties today? Smiley

Seriously, though, tiresome or not, you have done a lot for this community. Hopefully KnC reads your data (and the other brave souls who have experimented and done the dev work for these units) and incorporates YOUR research in their next batch of miners. Should resolve a lot of issues with what appear to be minor tweaks to the design/case layout.

I also hope that they throw some coin at all you early adopters who stuck your dick out and came out longer. Because of you lot, by the time I can buy one of these units, a lot of problems will already be resolved.

Thank you.


put it this way, even if someone did go off a limb and post something that didn't turn out to be 100% cause/effect, it usually will lead to someone else who is also testing to share and get to the right reasoning

but those that want to just play 'peer review asshole', well you see what that does to the soup

 

Personally I read what people say and decide if it's sensible or not, but as I'm nowhere as good at this I appreciate the theories and discussions and learn as they go on. No-one takes random theories as gospel until it's been generally accepted as proved, and anything we do to our rigs is our responsibility at the end of the day. This thread has been incredibly interesting and productive lately and I thank everyone who made it so. Smiley

I have more cores running now on 0.97 but also have more HW errors, and in the end my pool hashrate is lower on average because of this.

Look at the file /config/init.d/cgminer.sh to see how to turn individual cores on and off, i.e.:

Code:
                       # re-enable all cores
                        i=0
                        while [[ $i -lt 192 ]] ; do
                                i2cset -y 2 0x2$p $i 1
                                i=$((i+1))
                        done

You would have to edit that cgminer.sh file to keep them off, though.  By default, it will re-enable what it can whenever it restarts cgminer.

You are very defensive.  Normally I just ignore all the voodoo I see people posting in this thread as ways to increase hash rate, but when it's particularly egregious, like claiming a 'warm BBB' can negatively affect hashing, then I have to say something.

Sorry to get your hackles up, but don't post nonsense if you don't want to get corrected.


one more time....  I never said anything about BBB heat and performance..please go find a statement of me ever saying that..  you chose to associate me saying 'it' with BBB heat and bad performance and not with you blasting someone.. that was my context..  go re-read with THAT in mind

you are the one posting nonsense and terrible cognitive skills - you just don't want to admit you jumped to conclusions and thought a simple point A to point B..  I was talking about you, not to you when I replied

got it?


I have no idea what you mean here.  I have not 'blasted' anyone.  You are the one with poor cognitive skills and a definite lack of reading comprehension.  I initially just asked the simple question of 'how could a warm BBB cause hashing problems?'.  The statement was attributed to you by others, and you made a subsequent post (that I quoted above) where you seemed to acknowledge that you agreed with it.  If that's not your position, fine.  You are the one who went on the attack here.  I have no problem with you.  Calm down.

Still waiting for hosted 39xx Saturn to go into production. Status: Paid. Not even a sing of burn-in on the configured BitMinter worker.

Just saw this on the list thread:
Hosting started, logon details received! Hang in there people, have faith!
Jupiter, order 38XX, paid for July 16th.
Here is hoping...

Disgraceful. Hope you get a good one and soon mate.

little tired of proving everything for people...  


Well, to be honest, making goofy claims like 'hash rate goes down when the BBB is warm' w/o any supporting facts does not do a lot for your credibility.


re-read my posts..  i talked about lowering the fans to the crossbars for the asic chips/boards to lower temps 5-7C..  i never spoke of what you said but why should you go back and read anything right?

if someone takes something out of context and you believe it, I cant stop you



I have read this whole thread.  I can't claim to have memorized every post you've made, but I took this post:



I would be interested to hear what the theory is behind that "field experience".  On the face of it, that sounds ridiculous.  I have seen stranger things though, so I am not gonna call BS just yet.


which was the main reason I didn't post it to the boards for 3 days and kept it to myself....

to indicate that you stood by this claim, and felt that after 3 days of studying the problem, you were confident enough to make it public.  Did I misread you?


jesus you are a waste of time..  need everything spelled out in a straight line??

I was quoted above your post about what I did in another thread...I assume everyone knows about my fan mod on the crossbars so that was the part I was referring to on 'didn't post it for three days'  and the reason for THAT PARTICULAR ITEM was because of tools like you ok??

now go complain to someone else about heat and the BBB ok?

soy, .90 crashed....and everything below .94 didn't work or help me...back to .95 square 1 again see what happens....

.90, knc if you are listening had great numbers for me, but not sure what why it crashed....

If they were to answer I'd guess they guess it's your power supply can't handle it.

soy, doubt it, its a cool master 1200 watts...should handle multiple saturns...what I think happens is the output current showed at over 50A for all chips cores....maybe it was too much juice there, need a firmware like .90 but that takes output current to like maybe 45A....

All the firmware's were run at least 24 hours without any reboot.
