yeah but 100% makes no big difference ~ 88°C - 90°C and i only get ~150 - 160 k/hash per Card. When i go up whith the intensity i can only go till 17 than my system hungs up. at 15 till 17 there's no diffrence between the hashrates any more =/ I don't know how other one's get 210 k/hash out of the 5770. When i mine Bitcoins i can go to 215M/Has per Card at 78°C with no Problems for over one year.

Reached the 95° only for a short moment when i was reading some settings in firefox (didn't recogniced it directly, went back to cgminer which was about 95°) - and closed cgminer instantly ....to risky but the cards have not been damaged o.O

greets Killa

are you at stock settings

this cannot be the Problem. My System is an AMD 1090t with 4Gb RAM. Each Card does have 1GB VRAM. I Got at least alarming temps when i let them run at stock settings and 100% fan at intensity 11 o.O - thats arround 120 k/hash per card. Temps go up till 90°C when they run more than 10 minutes.

It will be the best option to sell this "two gpu crap" and invest in one better graphic card ^^ They did there job when bitcoinmining was more rentable but on litecoin mining i can nearly use them to cook water o_O

My 1090t is pushing arround 32 - 36 k/hash at 48°C witch an Scythe Kama Angel on it. - then i got an X4 945 who's getting arround 28 k/hash at about 54°C with an stock cooler.

it's about 23 - 25°C - even cleaned out dust from both of my Computers (which i do normally every month), they heat up. maybe the tower itself is the Problem (only a light aluminium case with an 120mm fan aside and an 120mm fan at the back -both pc's of mine had the same tower and nearly the same fan's), but when i mined bitcoins, i did not get these Problems. When i play games, the cards didn't heat up that much. Only when i try to mine litetcoins +-90°C per Card and 120k/hash each o_O MSI Afterburner even shows no full load of the cards....the first device is used arround 94% and the second with 88% usage.

meanwhile i tried another litecoin miner called reaper. reaper automatically selects the work for all devices....but there i only get 160k/hash out of both cards together with arround 60 - 70% load -.-

i think i'll mine optionally with my cpu's, sell my gpu's and buy me one good gpu =)
