Uptimes are impressive, like 7 was on my last machine....


 I haven't been impressed by uptime on ANY Windows system I've worked with - a couple of the older "server" versions could achieve TOLERABLE uptimes (NT 3.51 SP5 was THE BEST on that by a wide margin), but no Windows system I've EVER worked with can even come close to the literal DECADES of uptime I've seen out of some of my older Slackware systems (which literally have never seen downtime except for power outage, hardware failure, or I had to shut them down to physically move them in the case of literally DOZENS of systems).

 I finally retired my ancient AMD K5 based systems last summer strictly because I didn't have the space to MOVE them, and their performance was low enough to not be worth the hassle of trying to MAKE space for them - those systems dated back to the mid-1990s, and the ONLY one that ever had downtime happened when I accidentially deleted the entire /bin directory - yet it kept running anyway just couldn't START any new processes 'till I shut it down to move it and had to reinstall.

 Appx. 20 YEARS of performance with ZERO downtime on 14 systems that were constantly running the DNet client or the Prime95 client during their entire existance, among other things (keep in mind that a lot of sites used to use those programs for STRESS TESTING on hardware) - show me a Windows system that can even THINK about claiming 2 years uptime before you even think about talking "impressive uptime".


 The BEST I've ever seen out of Windows was a little under 2 years out of a Dell server at a place I worked for a while, running NT 3.51 SP5 and not doing a lot of heavy work (fairly simple web server and ftp server for driver downloads).

unfortunately, XP days are almost over as almost no browsers can be installed or updated.


 No updates is a nuisance, but they can all be installed - just not always THE most recent version.

 What's really irritating is that AMD essentially stopped XP support close to 3 YEARS before Mickey$loth finally got around to it - while NVidia supported XP for at least a few months PAST M$ dropping it.
 There's a REASON my remaining XP "older games" gaming and media systems sport NVidia cards now (first once I had bought in many years at the time I bought them).

Tried diffrent drivers on my R9 Nano. No "asm" so no speed update... Funny that 290 and 7950 work just great

As mentioned above, use 16.3.2 with fijis.
You get interessting result with this driver on R9 Fury family ?
I got 9 x R9 Fury something like 330-370 H/s (-45% power limit)
With -asm 0 -a 2 parameters.
http://www.monitorig.com/#?panel=dashboard&id=1086db9224632d26671ab42df5ee1d92bf0187bbdd

400@-96mv with 16.3.2 lots of nanos, pro duos...
I can't find a link on this version Sad
Always redirected to latest version on AMD support ... Do you have the link ?

 There should be a link to "previous versions" on the page for the latest version.

have on gtx 750 this error:

CUDA error 'an illegel memory access was encountered' in 'func eq_cuda_context<RB,SM,SSM,THREADS,PACKER>::solve' line 2095.

is miner suport gtx750?

 GTX 750 ti doesn't support CUDA 8 as I recall, so probably not unless you recompile.

v11 was "add asm code for specific older GPUs", no change for RX series from v10.

Claymore DID mention he was still working on upgrades for the RX series, probably asm as well.


 ZEC seems to be getting fairly close to full optimised, when the coders are having to go to GCN Asssembly code to get any further upgrades in speed.

Maybe because every Windows since XP has sucked in progressively more intolerable ways?


 Make that "since NT 3.51 SP 5" and I'd agree.

 Though NT 4 SP 6 and 2k SP 3 were tolerable.


 The UI on Win 8 was totally unusable.
 The "send home too much info to Mickey$loth" built into 10 is totally unacceptable.
 I strongly suspect 7 is going to linger on for a LONG time much like XP did 'cause a lot of folks won't be willing to put up the with newer junk (corporations in particular seem to be VERY slow at adopting 10, and almost NOBODY had any use for Cool - DESPITE the issues 7 has, which are *relatively* minor compared to the newer junk.


4167  Bitcoin / Mining speculation / Re: Is the current market downturn proof that mining is too centralized? on: January 12, 2017, 09:15:39 AM
The network's difficulty didn't go down when the halving happened.
 

 Error. The hashrate and difficulty DID drop some when the halfing occured LAST SUMMER - but there was a "new generation" of miners being deployed in that same timeframe, which had already taken over the majority of network hashrate and remained profitable despite the halfing - and continued sales quickly drove the hashrate back past the previous high.

 The current market PRICE downturn has nothing to do with miners - it is STRICTLY AND ENTIRELY due to the Chinese Central Bank (with is part of their GOVERNMENT) announcing it was investigating the large Chinese exchanges for stuff like "potential money laundering, market manipulation" and such.

 It's not MINING that's too centralised, it's Bitcoin OWNERSHIP that is very centralised in one country.

 (Ditto Litecoin and many if not most other newer altcoins).


 RESIDENTIAL electric rates in many parts of the US are less than 10c / kwh - and there are quite a few of us SMALL miners paying less than 5.
 While the majority of Bitcoin hashrate is no doubt generated by various major farms, it's entirely possible for the small miner to be quite profitable with proper planning and location.

In return, I helped him build a 6x480 rig using a 4U case which I was also interested in before this Panda came by.


 That case pictured, *IF* it is rack mountable, appears to be an 8U case.
 It's not even CLOSE to being a 4U case.

 By specification, a 4U case cannot be more than 7" in height.

Just to let ya know, Claymore said this yesterday for Zcash (ZEC)

"I will release new version with good speedup within 24 hours."

Geeze lol! Why does he keep spending 95% of his time on ZEC when it has been well below both ETH & XMR in mining profitability for many weeks in a row now?  Yeah, I get that there is not much more room for improvement with ETH mining but XMR seems to have some room, esp for 470/480's, since those were not even out when he made his XMR GPU miner.

 Per Wolf0, there is NOT much room if any for significant optimisation on XMR for the 470/480 series, the current miners are already well optimised.

 ZEC on the other hand still has quite a bit of room for optimisation it would appear.

You might take a look at https://github.com/nicehash/nheqminer
at least for NV its nicehash source of their solver

also Claymore 11 started using assembler and he managed a lot to boost a speed for older AMD HW as tahiti, hawai (280x, 380, 390, fury, nano) etc, no RX optimization

I am planning to port my stuff to nheqminer as well.
 

 That's "in addition to sgminer" not "instead of sgminer" I hope?

 The only thing nheqminer has going for it is if you WANT to work with NiceHash for auto-switch algorythm mining - overall the sgminer interface and controls are a TON better.

R9 Nano and Fury wont work on the 16.11.5 drivers. I'll try the new 16.12 drivers and see if it works.

Just tested: R9 Nano and Fury, aka Fiji cards will not work on 16.11.5 nor 16.12.2 drivers.

 Try 16.10.1 (last pre-Relive WQHL version).

i dont belive u can get 480v power at most residential locations

 It's not standard, but if you're willing to pay the cost it CAN be done at many or most residences - most of the cost would probably be the installation of a 440v 3-phase transformer, but the wiring would add some too. Standard distribution in a neighborhood from the substation is normally 3-phase at 10kV ballpark.

You should be able to use a stand-alone cryptonight miner and just point it at the appropriate Nicehash pool for your 750Ti

I believe you need the actual "core" wallet to solo mine against.

 Also, you will LOSE MONEY trying to mine any Scrypt-based coin on a CPU or GPU based rig - even with free electric you'll kill your machine long before you mine enough to cover replacement cost.


I disagree. I have recovered significant portions of my Scrypt ASICs costs, and then sold the rig for more than enough to make up the difference, ending up with a net profit.


 I didn't say ANYTHING about ASIC mining in the post you replied to.
 Please pay attention.

Depends on the card - I believe all 480s have at least one  HDMI port, some of us use a standard "HDMI to VGA" adapter as a dummy plug 'cause they're cheap common and work.

 The "dummy plug" trick originated on older cards that had DB9 VGA outputs, but the issue with Windows/ drivers for Windows has persisted for years.

Phil  did you ever see these?


http://www.newegg.com/Product/Product.aspx?Item=9SIA27C3GN8656

They have a resistor  and plug inline for 3 pin fans.  5 for 6 bucks.  So 2 orders for 12 dollars  would be enough for all 9 fans in the PandaMiner.


I like them  not sure is they can carry a 0.80 amp max load.

For 12 bucks I will order them now.  They could make the miner much quieter.

When my pandaminer does zec  the heatsinks are only about 40c

 I think I'm reading that as they have 47 ohm resisters in line - which is gonna drop those Deltas to 3 volts or so *if* I'm correct and the fans won't turn at all a that low a voltage.
 Might be 4.7 ohm though - the listing is VERY unclear - which would be a fairly small voltage and speed drop but the resistor better be a lot bigger than it looks like (at LEAST a 2 watt and even that would probably be very marginal at best, 5 watt would be better for some safety from overload and overheat).

HD 7870 up to 133 sol/s on V10 (was 120 on v9.1 previous).

 HD 7750 essentially unchanged at 53.

 My only concern is the summer... Even in one room with AC they generate heat above 35 C so that a second AC in the next room is not capable of stopping the hot air. Huh


Do you purposefully have your PSU mounted so that the heat is blown straight up into two of your GPU? Smiley


 Standard ATX-type power supplies with large right-angle airflow fans like the one in his picture suck air INTO the supply with the fan, and it blows out near the power plug.
