Haha yes both my sapphire 5870 vapor x went to the usa but where perfect able to run at 0.900 volt 750 mhz on core and 166 mhz on the memory
They are still awesome cards and i think the new owner is very happy with them.
I remember i often bend over towards my computer to make sure they where running fine ( so silent )
And yes i could game on them also while mining with no problems ofcourse not with the graphics power of these but still.

Do not get me wrong the 7970 i have now are monsters and i love them but underclock/volt wise they are a pain in the ass they just want speed and more speed
So a bit underclocking is possible but not much, undervolting does not work either, so far it seems that the cause of all this is ELPS the advanced power save build into the cards. This far i have not been able to turn it off completely i would like that though so i can proof if my theory is right.

Maybe someone has advanced knowledge at ati bios matter and would like to help find out if its possible to turn it of by flash the bios with a alternative one

Yes you asumed correct for me and my high electricity costs its allways been the goal to undervolt / underclock at best hash result.
But i also want to keep gaming and yes i want to game when mining for that i reduce the graphic needs in the games to about medium settings, which does not affect my mining at all

So yes i can play World of Tanks at medium settings and the miner does not even show a small bump 

However this far i am very pleased with the new driver set from Amd.
Installed catalyst 12.4 and guess what it runs stable now even at 800-1250 on the core and 800-1550 on memory (min -  max)

To make matters clear as soon as i set the memory below 800 the crashes appear again, that is when mining and using some programs like games, video processing tools and sometimes even with winzip or rar

My cards also tends to crash if the difference between core and memory speed becomes more then 150 mhz again speeding it up does work fine but when trying to lower the speeds the crashes start.

However need todo some more tests with the newer driver and cgminer 2.3.6 to see if i can now go below the previous limits.

This far 800/800 has been the most silent, efficient and coolest miner setting but time will tell (74 c gpu temp).

Hoi Wasta

Je mag contact met mij opnemen dan zal ik samen met jou proberen tot een oplossing te komen
Bitminter is een soort pps maar vreemd genoeg duren de btc blokken bij deze server al een heel lange tijd veel langer dan bij andere pools. En deze pool vindt ook op namecoins blijkbaar veel minder blokken dan alle andere pools.
Ik heb er een hele lange tijd mijn pc op gehad maar op een gegeven moment vond ik het toch wel allemaal heel apart dat andere pools minstens 5 tot en met zelfs 20 namecoin blokken vinden op een groter btc blok en bij deze pool amper tot helemaal niet.
Maar goed het delven van de munten word ook bepaald door geluk met het aantal delen wat er benodigd is om het munt blok te vinden.
Daarom komt het dus voor dat een uitbetaling soms verschrikkelijk lang kan duren, er zijn zelfs blokken welke tot wel 21 miljoen delen groot waren/zijn.

Voor het delven met verschillende snelheden en opties is het eigenlijk een must om het programma cgminer te gebruiken welke verschrikkelijk veel opties heeft en waar je allerlei mooie instellingen kan maken bijna geheel naar wens
Je zal op alle servers wel eens failed of denied zien maar over het algemeen is het normaal als je hele lange reeksen van accepted ziet, dit is een klein beetje afhankelijk natuurlijk van je verbinding tussen jou en de server.

Je berekening zou in een perfecte pool wel aardig kloppen maar op een kleinere pool dan slush of deepbit meestal niet haalbaar, ik delf met gemiddeld 1600 M/s

Ook de gemiddelde energie prijs is niet 20 ct/kwh maar 23 tot 31 euro cent / kwh dit omdat inmiddels de staat weer een belasting verhoging van energie heeft doorgevoerd waar veel mensen amper tot niets van gemerkt hebben
Eigenlijk is in ons land als je net als mij de energie rekening zelf moet betalen helemaal niet winstgevend, tenzij de prijs van bitcoins na de halvering straks ineens in prijs zouden verdubbelen.
Uiteraard zou dit voor de oud gedienden die honderden blokken hebben behaald in de makkelijker tijden, een mooie winst kunnen betekenen van weer eens 100%.
Maar goed dat is en blijft koffiedik kijken, want niemand weet wat er dan gaat gebeuren.

Het instellen van je kaart op een goede snelheid en toch niet al te veel lawaai maar nog wel een goed resultaat behalen noemen wij undervolt/clock van de kaart welke je gebruikt.
Helaas kun je met de nieuwere modellen 69xx en 79xx niet zulke prachtige instellingen maken als met de zeer goede 58xx/59xx serie kaarten. Deze bleken voor mij perfect te kunnen worden ingesteld op erg laag stroom verbruik met een toch meer dan redelijke hash snelheid.
Toch kun je nog wel het een en ander voor elkaar krijgen op deze kaarten, dit is dus onafhankelijk van welke pool je gebruikt om te delven.
  
Welk merk is je video kaart en weet je zeker dat het niet een andere oorzaak is ?
Ik kan het natuurlijk hiervandaan in kampen niet horen of zien, maar soms zijn het echt vaak kleine dingen welke je zelf soms kan oplossen.
Tenzij er gewoon dus echt een fabrieksfout in zit dan zou ik de fabrikant helemaal gek gaan maken

Helaas zul je inderdaad met die kaart niet meer halen denk ik, het is wel degelijk een andere kaart dan de 6850 maar denk niet dat deze veel sneller zal zijn


http://hexus.net/tech/reviews/graphics/36269-amd-radeon-hd-7850-vs-6850-vs-5850-clocks/  << hier kun je goed de verschillen zien tussen de verschillende modellen.

ondanks de hogere nummers is de 5850 dus nog steeds de betere voor het mijnen van coins.

voor games is de 7850 geen slechte kaart

my sapphire 7970 3gb oc does not really like memory lowered
putiing it on faster speeds is no problem factory wise it runs 950/1000 on the core and 5700/5800 (1425/1450) on the memory
somehow this card loves higher memory speeds because it goes easy to 6000+ (1500+)
but since that produces a lot of heat i stopped at 6060 mhz
anyway when i lower the speed on the memory under 1200 mhz my pc starts to crash when i run games
i can set it at 1000 for instance and will run but programs simply crash on different moments
upping the mem and all runs stable as a rock

currently i run at 1100 core with mem at 1200 producing 653 Mh/s
 

Well i fear my 87 bitcoins invested are gone, no updates nor answers on emails
Wigglyuk might be right bitcoin attracks alot of shady people as the many ddos/hack attacks shows.
In many ways people are trying to get you to send them your money and never send what you paid for, which is what happens alot with bitcoins too.

It depends on how lucky you are i have been mining for like 11 days finding non and other times finding 3 blocks in a day
There is no way to tell how long it will take to find a block, at present not worth mining for me since the difficulty on all coins way too high for my energy costs

Well i dont know about others but i get lots of pool connection warnings, and constant seeing caching submissions.
But worst of all is silence ..... my fat 7970 often silent is not good

Gaat prima met intersango mocht het niet zo goed werken of te lang duren kun je op freenet irc server in #intersango terecht voor hulp
Zoals altijd met irc zul je online moeten blijven hangen tot dat diegene die je nodig hebt reageert ( PhantomCircuit )
Tot dusver ben ik tevreden over intersango het werkt gewoon

BTC Poolwatch

I really do not understand why you think p2pool is the solution
This idea not really made for huge mining power or at least as far as i know long from ready for handle such a thing
For the miners who switch between pools its absolute a fail because it does not keep your mined shares....
My experience with this so called p2pool has been not very good and costly.
The only solution is spread mining power over more pools, but as you can see people like the huge pools more then the smaller ones
Smaller pools hardly get more hash power because people want a steady income.
But its the chicken and the egg problem small pools can not produce steady income unless they get more miners todo so.

About block size i think there is no limit on how many shares a block can be
We saw last time ozcoin hitting 21 million or something and they had earlier also several huge 12 million+ btc blocks in the paste so ..... 7m is bad and nasty but it can be much bigger as been proven
Now do not get me wrong i do not like those big ones one bit and i think maybe there should be a max possible blocksize somehow
But i fear its not going to happen, you either am lucky or on each round  ...

oh god not just another flame windows thread ..... dude if some hates linux he should not be flamed
i can run linux but yes i hate it .... its not the uber os PERIOD. Its just another

driver 12.x needs a hack in the register to make the memory and proper downclocks possible
google for it you only have to edit one line in register to make it work

Well regarding over or undervolting cards
There is not really a easy answer, it all depends on how the card its bios is made.
I found my xfx and sapphire vapor-x cards not allow any underclock or overclocks besides the 3 steps programmed into the bios for the different power states programmed in the card
I had before some 5850 cards from asus who actually responded well to any overclock tool and settings where i could put in any value i liked, even which where much higher then factory allowed, so even though i set afterburner to allow voltage changes they simply refuse todo so

But the sapphire/xfx are not responding at all to any of the tools available (trixx, afterburner, adams tray tools) even the amd overclock tool crashes with the message no cards present. So i am stuck to be able to change only mhz on mem and core and thats it.

I have not read any people being able to flash these cards succesfull with asus top bios version so i kinda not dare todo so either.
Although i am sure these very well build cards could do much more with some slight overvolting

 

(it just depresses the price a little)

A little lol its worth nothing thats not what i call a little

A mining buddy Eliden got some weird problem with all versions of cgminer from 2.0.7 to 2.1.2

http://img841.imageshack.us/img841/6650/88077886.png this is the screenshot

The temps and the rpm of the fan disappearing on start of cgminer

Well most funny of all is that sapphire and xfx are from the same owner.
But  to be exact the XFX has limited life time warranty. But i agree its a top card not an B brand
I got 2 problems with my cards and XFX allways helped me to get a solution.
For me XFX is even better then all the others

The card has been tested under full load pulling 192 watt by a hardware review site who had their hands on the first cards
That full load was doing a heavy game for a certain amount of time, they also mentioned that if you overclock the card it will use more then 200 watt.
And including burnin with furmark now do not tell me you do not know how powerfull furmark is
Its actually more stressing cards then they will ever do in real time usage including mining

This site has allways been in this respect good they test every aspect, and i believe they did more testing then others
So there is no doubt about the results, these guys test with better equipment then a kill-a-watt

Onto the answer with the threads running in the old stucture the alu where not capable of doing more then 2 threads
the new GCN seems to make it possible to make better use of the alu's is stated by amd.
So somehow you can get the card to set every and all alu to work
Which was simply not possible on the vliw architecture
The big increase in numbers on the review (most games) shows clearly that this card easily does up to 33% better then the 6970
I think for the coders out their this card poses a real challenge to get more out of it then with previous cards.
Nevertheless we have to wait what prices it will get at, after the initial run on them because i already know many of the gamers i talked to want 1 or more of them as soon as they can

Ja ja leek al te mooi om waar te zijn he
En jawel sepa komt nu echt in 2013 .... ow nee toch niet het word nu weer 2014 hup holland hup word de laatste
