Šta je novo?

Bitcoin [BTC] (SHA-256)

Trebalo bi da moze ali treba jos ispitati ..
 
Ja mislim da moze bez frke. Ja guram nasvirane dve na mojoj masini bez ikakvih problema. Mislim da imas toliko lufta da uglavis jos jednu.
 
@markoarsic
sada su cene nize za ~25e

@rapture
ja sam terao 7950+7950+7970 sa default naponima i 960mhz klokovima na pc power and cooling cilencer 750w, koji ima koliko ja znam, seasonic unutra.
sa corsom tx om i cwt-om unutra....lichno se ne bih u to usudio....mozda moze, aaali....
 
Mada imam jos jedan stari chief od 400w, mozda bi mogao on malo da pripomogne :D, sad mi krvo sto pre dva dana nisam kupio coin-e po 15.5 $, gledao cube zero na tv preko noci i malo pratio vrednost :D...






P.S. ima overload protection....

@rapture
ako to napajanje ima overload (mrzi me sad da guglam) i ako bude preoptereceno ono ce samo da se ugasi tako da neces imati nikakvu stetu ....
ja sam stavio na SilverStone ST60F ES 3x5850 kloknute na 900MHz i rade bez problema...

inace po meni su ipak za mining bolje kartice 5 serije zato sto su vec postigle neku niminalnu cenu ispod koje nece ici a period otplate im je bar duplo kraci od kartica 7 serije . da navedem pirmer da za jednu 7950 (500-600MHash/S) koja kosta ~300e imas da kupis 3x 5850 koje sigurno daju 1050MHash/s i trose nesto vise struje u odnosu na 2x7950 koje daju ~1100MHash/s ... tako da je moja racunica jasna ... ovaj izlet sa karticama 7xxx serije mi je bio promasaj i lagano se vracam 5xxx seriji ... ovo su cinjenice a sad ko prema cemu ima naklonost to je drugo..

5850 su odlične osim ako uspeš da uloviš polovne ali još u višegodišnjoj garanciji HD7850 1GB (za oko 115-120e). Svaka oko 320-350Mhasha, zavisno kako se klokuje, a troše znatno manje struje od 5850 i jedva se čuju (dakle može i u sobi da se drži). A sa očekivanim znatnom porastom cene struje (realno, cenim oko 25-30% viši računi), ovo će biti nezanemarljiva stavka. Uz to, 5850 polako izlaze iz garancija što će im umanjiti cenu i povećati rizik (ako neka crkne, ode ti dosta para...)

serija 5 je odlicna, ali najveci problem sa njima je garancija. Skoro sve su izasle iz garancije. Evo meni je skoro crkla jedna 5850.
 
....garancija i potroshnja su problem. sada kad struja poskupi, to ce biti josh gore....79xx rocks all around.
 
Da vam malo pravim zazubice :p

MSI 5870 Lightning.jpg

Dva komada nova (reparirana) sa garancijom od 36meseci za 140€ po komadu. Naravno nema više, da je bilo uzeo bih sve što imaju. 450 Mhash/s.

Imam nov primerak 7850 placena 15.000 dinara pre 2 meseca maksimalno daje 325mh a da je iole stabilna. Radi na 1130 klok vent 52 a temperatura oko 60c !
 
Serija 5xxx je odlicna ali mislim da je odradila svoje. Ko je ima njemu je ok da i dalje radi s njom ali kupovati sada takvu kartu... Neka hvala. 7850 je za svoje pare bombona.

@ Paradigma Edit: Cestitam na kupovini, lepa cena ;)

To je to. Kod mene samo malko bolje, 348.5Mhasha na 1180MHz, vent 53% temp 64C, dakle sasvim OK. Plaćena 13.000 dinara, još 32 meseca u garanciji.

Kod mene nema pojma da radi preko 1130 nemam pojma sto?

M_M sto ne spustis clock memorije?

U pravu si, mogao bih i uradiću... Ostavio sam memoriju na defaultu, nisam ni razmišljao mnogo. Uštedeo bih nešto malo struje, ali ne verujem da bih izvukao veći klok GPU-a čak i da smanjim takt memorije, jer nije problem zagrevanje već jednostavno je to realni maksimum kojeg GPU može da izvuče. Probao sam GPU i na 1200MHz sa 100% ventilatorom ali s vremena na vreme zabode, tj. drajver restartuje... A ne može ni dizanje voltaže preko 1.225V, tako da to je to.
 
Da, to je to. Udario si u limit. Ali bar memoriju spsti zbog temperature, znacice joj a i samom ventilatoru.
 
registrovao sam se ovde samo da pitam ovo pošto vidim da ste ovo najjaktivniji oko ovog. Imam problem sa BAMTom tj ne umem da ga podesim kako treba...

i bamt pools

Kod:
# BAMT pools file
#
# Specify one line per pool.  The simple form is just the complete URL
# including worker login, for example:
#
# http://yourmom:[email protected]:8332/
#
# If the pool specified on the first line doesn't generate a share 
# within the allowed window (180 seconds by default), BAMT moves to
# the next line in the file (or wraps to the beginning)
#
# By default, BAMT will not change pools unless there is a problem
# with the one it's using.  This means if it switches to the second or third
# pool in your file, it will stay there as long as that pool keeps working.
#
# You can have more control failover/back by adding one or two numbers to the end of 
# the URLs, seperated with commas. For example:
#
# http://u:[email protected]:8332/,10,60
#
# The first number is the maximum shares to complete before exiting. The second 
# is an optional override for the default pool_timeout in bamt.conf 
# You can omit the max shares if you only want to override pool_timeout by 
# leaving the number blank, ie: url,,number
# 
# You can also specify a backup URL to Phoenix.  Phoenix will attempt to pull
# work from the backup when the primary fails.  It will try to return to the 
# primary automatically.  The maxshares and pooltimeout apply to the phoenix
# instance as a whole, and shares from either pool count towards them.
#
# To specifiy a backup pool, put it in the 4th position.  You can leave the other
# fields blank, but you must use commas to delimit them in any case.  
#
# All parameters specified:
# http://u:[email protected],10,60,http://u:[email protected]
#
# Only primary and backup specified
# http://u:[email protected],,,http://u:[email protected]
#

# At very least, change the next line to a valid worker url:
http://user:[email protected]:8332/

Nisam mogao da cekam..
stavio +5 i 1150 za sad radi, daje 332mh...

@Paradigma
Vazi kume :)

Nego da pitam nesto... Kakva iskustva imate sa 7950 ?
Koje primerke imate i koliko realno daju sa nekim normalnim klokovima? Ako uopste znamo sta je normalno :)
 
Gurni bre to na +20, sta si se uplasio :D Time joj samo ogranicavas overclock i gubis stabilnost sa istim.

Kod mene odlicna iskustva, pored te 7850 imam i 7950 koja kopa na 1180mhz bez problema tako daje 610mhash-a ;)
 
ja sam imao nedelju dana 3x 7850 MSI one najjeftinije sa 1GB rama i mogu da kazem da moze iz njih da se iscupa i celih 340MHahs/s na 1150 ali nisu stabilne, na 1100 rade stabilno i daju nesto manje i to su po meni mozda i best buy iz 7xxx serije jer trose malo struje a daju skoro kao 5850 koja trosi undervoltovana i 40W vise.
 
Poslednja izmena:
Meni jedna MSI7850 1gb radi na 1150mhz i izbacuje 340mhash-a, jos je kao primarna karta
