Title: HD 5770 AT 100 DEGREES Post by: yamato57 on June 18, 2011, 06:20:48 PM My sapphire HD 5770 IGB runs at 100 degrees when i run the phoenix program at the clock core of 850 which is the default. Does anyone know why this is happening?? ???
my setting on phoenix is http://username@deepbit.net:8332/ -k poclbm DEVICE=0 VECTORS BFI_INT AGGRESSION=8 WORKSIZE=128 Title: Re: HD 5770 AT 100 DEGREES Post by: zerokwel on June 18, 2011, 06:37:37 PM toasty saying that mine runs at 90 higher with the side of the case on :). 120mm fan on the back of the case has packed in I need to replace it. and this is in a aircon room as well

Title: Re: HD 5770 AT 100 DEGREES Post by: yamato57 on June 18, 2011, 07:27:55 PM weird thing is my 6990s are at 100% fan and only at 80ish degrees and in a 90 degree room with giant fans. this one is in a ACed room could it be cause i recently flashed my bios cause it was stuck at 500MHZ and now its fixed to 850??

Pretty sure you mean 100C, turn the fan on the gpu all the way up, get better cooling too. Title: Re: HD 5770 AT 100 DEGREES Post by: Sebz4n on June 20, 2011, 12:51:05 PM Try under-clocking your memory core to 300 MHz, are you running a crossfire setup?
Title: Re: HD 5770 AT 100 DEGREES Post by: yamato57 on June 20, 2011, 02:13:35 PM i turned down the memory clock to 600 and fan speed at 100% and its running at 91 ish celcius. Is that normal??

Make the fan speed 100%, and try taking the side of your case off. Typically this will reduce the temp of the card by 15 to 20 C right there. Also, if you have other cards that are near your vid card, like sound cards / tv tuners and such will make the card warmer just being near it and not letting the heat escape. Try punching out extra metal covers in the back of your case as well to allow increased air flow. One last thing, take a desk fan, and blow it directly into the computer, this is usually good for a 5 to 7 C lowering as well. I run my 5770 at 970/300 and the temp never is higher than 70C, usually at 68C.

Also I found that poclbm was more stable and ran cooler for own three rigs having six overclocked 5770s running at 60-70 C. Title: Re: HD 5770 AT 100 DEGREES Post by: Dale on June 23, 2011, 07:24:02 AM Try dropping your AGGRESSION to 8 or below. Yes, You are right. Overclocked to 960/600 XFXs 5770 with 100% fan speed, temperature is 63-65 C. Two 120mm fans blowing air through case.Also I found that poclbm was more stable and ran cooler for own three rigs having six overclocked 5770s running at 60-70 C. |
