5970 mining thread

[Sant001]

How much power one needs to power 3x to 5x 5970s?

I have 2x 5970 at 1200W, the moment I try use 3x the thing gets really unstable and I can just assume it's due to insufficient power.

Running them with under clocked memory/default core/default voltage.

Plan for 200-300 W for each card. I'd say that PSU can handle 3 5970s at stock settings, or 4 if you undervolt. Do you have a killawatt?

I think my PSU needs a replacement... What's a good PSU to run 4x 5970s? Perhaps I will need to use 2x psu's on my setup

has anyone found any major difference between mining of different flavors of 5970 like arctic cooler, black edition sapphire ?

I have a reference and non-reference running in one rig, no real problems other than the fact that after changing the fan on the non-reference version, one gpu runs much hotter than the other.

Sorry, I don't have experience with arctic cooler or black edition 5970s.

thx man ......just for info Arctic cooler is with 3 fans ..and black edition is the one scored the highest with Diablo on the wiki page for performance..863 MH....

sorry for bump

i got two readon 5970

i trying them for two days for litecoin mining.

i tried many .bat configs but i couldnt made them stable.

sometimes they get 90 temperature, sometimes they suddenly stop mining.

finally i put them off and inserted my powercolor 7950s

actually 5970s are mining about 700khs

7950s are mining 580khs

is there a way to run my 5970 stable?

[dmcurser]

im guessing you got them used have they been rethermal pasted is the fan spinning up to speed and holding rpm?

90 is to hot.

You should use software that can control the GPU fan speed and crank it up to max, and put big fans blowing on the cards.

Old-skool mining pic of what is appropriate:


Also, 5970s are power hogs, the max power rating at stock is 290 watts per card, your power supply might not be able to keep up.
