non-specialized equipment -> specialized equipment = more centralization


not that it really matters in this case

payment on this would be in bitcoins up front, or cash in person

i'm definitely not shipping overseas w/o getting the bitcoins first.   but, yes, if you want to pay me the bitcoins then i can see how much it'd cost.

i'll also make the same offer i made that other guy:

i could also toss in another 5870 that doesn't post at all, but still has value i assume (heatsink is on it, if nothing else...  and some handy pins you could solder on to the card that's missing 2).  it doesn't have a backplate or shroud 

and a 5970, which i'm 95% sure doesn't work, but not positive.  it used to be watercooled and i don't have the original heatsink & fan for it.  i was told it didnt work & never really bothered to test for myself.   just the card itself, no heatsink or anything else.

they are useless to me and just taking up space

make me an offer on 4 working 5870s, 1 "sorta damaged" 5870?  the damaged one is just missing two of the pins for the fan power connector on the card.  two of them are missing backplates.  four of them have the ATI reference fans in them & still working, the fifth "sorta damaged" one has a fan ziptied on it and the shroud removed.  can send shroud separately & also a reference fan that works.   don't have the two backplates, no clue where they ran off to.  in essence, 2 are in "normal" condition, one has a backplate with a fan ziptied on to it, w/ a shroud I can include, but the fan power connector doesn't work because a couple of the pins have broken off, the other 2 are in normal condition except for a missing backplate.

2 are asus, 1 is HIS, 1 is XFX, and 1 is unknown.  all are reference cards, 1GB memory

i could also toss in another 5870 that doesn't post at all, but still has value i assume (heatsink is on it, if nothing else...  and some handy pins you could solder on to the card that's missing 2).  it doesn't have a backplate or shroud 

and a 5970, which i'm 95% sure doesn't work, but not positive.  it used to be watercooled and i don't have the original heatsink & fan for it.  i was told it didnt work & never really bothered to test for myself.   just the card itself, no heatsink or anything else.

Ah, that's part of the issue of avoiding eBay!  I did just go ahead and look and there's only one that I can't easily determine the model of (w/o pulling it from computer)...  because if they weren't ASUS, then they got a different bios, where I could overclock easier =p

Two are ASUS, one is a HIS, one is XFX, and I'm not sure about the fifth.  They're all reference model 5870's & 1GB memory.  

I still have screenshots of them "in action" at www.nogleg.com/temp/1.png www.nogleg.com/temp/2.png www.nogleg.com/temp/4.png (I removed 3 & 5, 3 was obsoleted due to one of the fans being pulled & 5 was unnecessary)  ... note that even though the screenshots were taken at ~7am, ambient temp in room was probably around 85oF, up to 110oF in the afternoons...   bottom right of pic 1 is to show the system uptime of 7 days, afterburner was never turned off, so those were the max temps the cards hit..  4.png just shows piddling with the clocks, back when it was colder in winter.  now they mostly run at 1.063v (hence the 390-430mhash).... the card that is showing the 54o temp and 68o on sensor 2 needs a new thermal paste job =p

the other two are @ www.nogleg.com/temp/5870-1.png and www.nogleg.com/temp/5870-2.png ...  in that case, cgminer had been running like 7 days straight...  i still run both of those cards at 1.163/1.15v since they're double spaced.. also shows logfile on the 2nd screenshot... where I changed some bios that was defaulting the card to 1.212v in performance level 3 (guess I could have used RBE or something also)

(the high number of rejected shares is because of the nature of p2pool)

another ed:  also, the discrepancies between the clock times shown on cgminer/afterburner is because i use barelyclocked on the 5870s

sold

Hop 1 is to my router which is <1ms and I've removed.  Hop 2 would be my DSL latency, the last hop is the latency to the IP running p2pool.

4 DOAs in ~30 shares.  I'm showing 2 orphans out of 90 shares total.  I'm not sure which 2 were orphaned, but I guess you could say I had 4.33 DOA/orphaned in 30 shares...  that's still >100% efficiency at all times (I don't think I've ever seen p2pool under 13.5% orphan/DOA, at least in the last 6 months).  Not 110-115%, but a couple weeks ago I also wasn't dealing with oversold bandwidth.  4.33 out of 30 would probably usually be around 105% efficiency or so.

Here's what the link looked like for those times:



This is in response to the thing about latency needing to be under 45 or whatever.  With my normal latency (180ms, and much less packetloss), I get about 5% DOA, instead of 10-15%.....

basically my argument about why the most important thing in choosing a node is the node's orphan rate..  then you look at your latency and see how much DOA that should result in...  but I don't see any reason why someone should have <100% unless they're on a satellite connection or something

I should really just be mining on a normal pool until my link is fixed, just too lazy to change everything around

ed:  added two more, link is still crap, 500ms+...  this is worst time of day actually, it'll clear up in about 2 hours

ed2: well, more like 2 1/2 hrs.  my theory is summer break

sent you a PM, there was one that might still be available (I posted it to 'friends' on facebook, but not on here...)

not worth my time to sell

the one before the block and the one after the block are from 185Kip6odGYs4eSHD6DYsWVDJBg2DNLfiV, though wouldn't that only matter if the next one in the chain was also 185Kip6odGYs4eSHD6DYsWVDJBg2DNLfiV? (as mine would have been sandwiched between the two)

ed:  ok, so the real issue here would then be that 185Kip6odGYs4eSHD6DYsWVDJBg2DNLfiV is operating at 2s latency or higher?   

all i can think of is that his client tossed out my share as being invalid, then he got another share and his node broadcast that share, and for some reason, my share got replaced by his.  that should only happen if he had gotten another one after that though, eh?  is there some other explanation?   because that could be abused

yeah, like this

Is there some easy way to take all my auctions down?  They haven't sold in 2 days and the prices are lower than what I'd get on ebay - fees anyway

i see a 'select all' button, but nothing that i can do with it except export my list to a csv file

settings -> sell settings -> out of office for anyone else that's interested, just found it

i guess that works.  not sure if people can still 'buy' your items if they have the direct link or not.  would suck for the instant digital items.

re:  Punishing share for 'Block-stale detected!, etc.

I get a lot of orphans when this happens... because my bitcoind is too fast?

I went to several other pools (my other one in Florida, OVH in Canada, p2pool.org, some others) and they all had my share listed, which means that it was accepted and got orphaned later.

This occuring after several:

... and then that share was orphaned.  It seems to me like if I modified the source to turn off the whole 'punishing share' stuff, I'd get less orphans?

be careful not to double list auctions on amazon (re: have it sell on ebay, then have someone else buy it on amazon)...  they are pretty quick to yank your selling privileges for new sellers

Two 5830's on Amazon for $84 + shipping (which amazon reimburses you for).  Amazon fees are a lot less than eBay.

On eBay, I sold two 5870's for $140 each and "free shipping" (clearing about $115 each, I'd guess, after shipping).  I paid a $20 fee to set up a shop (for one month) that reduces the commission amount like 5%..

Shipping costs a bit more since (imo) for anything over $50, you should require signature verification

what makes you think you know the answer to everything?

you state here you have the same efficiency as I do, yet you mention something earlier to the effect of not mining on a node that has >40ms latency?

how about this (ed: consolidated into one image):



Go ahead and get 115% efficiency with 500k blocksize on that, chief

that's called oversold DSL bandwidth and sunday afternoon/evening... the last hour is called game of thrones

well, if you include the evenings of 500ms ping times and the packetloss, it averages out to around 5-6% DOA (weekends are worse than weekdays), add in 2-3% worth of orphans and so then theoretically efficiency would be anywhere from 110-117.  (this would have p2pool as a whole ranging from 18 to 25% doa/orphans)

it's hard to say what mine is exactly, since i have multiple people using my pool.  the 108% right now is worse than normal, but that's because 2 out of the first 5 were DOA.  i reset it this morning at 300 shares, 4 orphans, and like 50 DOA.   the DOA mostly from ASIC not working properly with p2pool

theoretically with a 1 second delay, you should only get 10% DOA?  if you're mining on a european node with plenty of bandwidth that's set up properly, you shouldn't get more than 2-3% orphans.   so, you'd still have higher than 100% efficiency

i use maxblocksize 5000, but i restarted this morning to experiment with 3000.

i run p2pool with about 60 nodes added as --p2pool-node and allow another 20 outgoing and 10 incoming

sure, I mine on a remote node at 200ms

my DSL alone has base latency of 35ms

ed: ok, more like 30-32ms

oh, it also gets like this in the evenings:

pro: you get to split an extra 0.96% in fees to everyone else (less than 0.25BTC), going by stat info on http://blockchain.info/stats   

con: you get a lot more orphans & more processing power is needed, not altogether related to the getblock latency, but actual transferring within the p2pool network itself

Did you buy the 7950's used?  I paid $269.99 for mine.... or are you counting rebates + games?


no reason to as long as they still sell for inflated prices on ebay and amazon

i've bought some 7790's, 7850's, and 7870's, just because as of right now if you do the rebates and sell the games, they become profit once they hit your doorstep
