Title: mining with 5970, gpu usage spiking Post by: hickc on March 19, 2013, 08:35:58 AM I am mining with a hd 5970, catalyst 11.12, sdk 2.1 and phoenix 1.7.5 on win 7 64 bit. Generally my gpu usage for both gpus is maxed out at 99%, but occasionally it will drop to 75% or something for a moment and then bounce back up. core clock is 850mhz, mem is 310 mhz, my psu is kingwin lazer 550w platinum (I know its not psu related, because even with a 750w antec bronze psu these flareups still happened). The temps are fine at about 50C for both gpus, so I was wondering does anyone know why this happens, what it means and how to fix it?
thanks for the help. Title: Re: mining with 5970, gpu usage spiking Post by: Gator-hex on March 19, 2013, 10:13:42 AM It's probably just waiting for the pool to send it some work.

1 pool to slow , what pool are you using? 2 some activity in the desktop i are you mining dedicated? all other progs disabled or minimized? 3 shitty riser or not plugged corectly and additionaly, its a sha256 or scrypt?

it is a dedicated miner with no background tasks how do i tell if it is sha256 or scrypt? everything is plugged in correctly Title: Re: mining with 5970, gpu usage spiking Post by: crashoveride54902 on March 23, 2013, 02:18:19 AM my pool is 50btc, i am located in the us. it is a dedicated miner with no background tasks how do i tell if it is sha256 or scrypt? everything is plugged in correctly pretty sure he meant btc or ltc? but i'm guessing btc...and it's probably just a pool spike...i mine on slush and notice sometimes my gpu useage drops down and then back up...no biggie as long as it doesn't stay down...

Seems for me like a temporary network problem on pool or local site, especially with one miner which is behind a proxy. http://s7.directupload.net/images/130326/t3mkkbqm.jpg Title: Re: mining with 5970, gpu usage spiking Post by: ddo on March 29, 2013, 04:19:00 PM I have a similar issue. When starting to mine both my GPUs run around 95% or higher, but after like 10 minutes my first GPU starts running at around 75% while my second is still around 94%. It basically stays like this after... Does this mean one of my GPUs are broken?
