im running 6 R9 290's on 2 boxes (watercooled) on win 7 and win 8.1

based on my experience on running the stock cards BEFORE i watercooled, you CAN overheat the cards resulting in a shutdown condition by doing a restart from the mobileminer.

try it, and youll c what happens!!

this is if u set your AMD settings to max of 95 C, youll easily hit 98 C or more by doing a mobileminer restart. watch out!!


my suggestion?

to get the max benefits of the card goto watercooling, try ekwb solution. its cheap and they have a great block for the card!

hacking the card is easy.


the r9 290 is a great card, too bad the supply of unlocked cards dried up!!


the 1st card i got i was able to unlock it and the 290 that i paid 399 for became a 290x !!!! (that one runs 820k/sec scrypt.


so both ofm y boxes together watercooled run maximum rates.

a 290 is good for about 760k, a 290x is good for 820k, without overlocking.

i get about 4.6 M on 2 boxes nice and watercooled :-)

i recommend u push pull the radiator fans, and use cooler master jetflo 120 CFM fans on them........ make sure u use a 12 volt connector too. runs nice and cool all day and all night :-)
