Flashed my Trifire 7970's to gigabit bios - now runs very hot.

post #1 of 38
Thread Starter 
Hi guys,
Sorry, been out of PC world for a while as been building a new business and its taken up all my time, but Black Ops 2 has brought me back to the PC of an evening. LOL

So,
I decided to try and flash all three cards over to this 1GHZ bios floating around, it went smoothly, no dramas and stock clocks etc have indeed increased to 1050/1500.

An hour or so's gaming shows no problems, however.... my cards all run significantly hotter than they did with it overclocked to the same levels. In fact, my main card reached 83c tonight and it VERY rarely used to exceed 60.

Is this what you guys have been finding, or is this an anomally?

On water that is really weird, too much voltage maybe?

Just been doing some benching, and card 1 crashes at 93c running HEAVEN 3.0 of all things.
All is not well... and it can only be voltage related really. Damn computers, its not as though 200fps at 5760x1200 over 3 screens is crap is it?

Why must we fook about with things?! rolleyes.gif

Because the cards get the juiced pumped up when running GHZ bios. i think stock for normal card is 1.175V Ghz uses 1.26V.

Under water they shouldn't go over 60-70 at them volts

My temps water cooled are 65C at 1.26V, but then again he has "3" Flash cards, i have 1. SO i would suspect that he needs to increase his flow rate.

But he said his top card hit 93c

Thanks for the input guys, will take a look when i get home from work and report back.
Looking at it with a fresh head (well, after 4hrs sleep...lol) I am wondering if I have a strange coincidental loop problem as I cant see the small voltage increase from this bios flash causing a heat problem like this. I can normally run BF3 at 5760x1200 everything maxed for 2 or 3 hour stretches without my fans even coming on, so that means sub 50C temps as they are set to kick in slowly at 50c. (I like silence) smile.gif

I probably have more water in my loop than anyone else in the world so it could well be the pump not flowing as I can actually turn my pump off and still run her flat out for about an hour before things get too hot. Odd it would happen at exactly the same time I choose to flash the cards after 6 months of being just fine though.

Will evaluate with a fresh head tonight and start with running her on bios 2 and doinga quick temperature datalog run with Heaven 3 and compare current temps to those of when I was benching her 24hrs a day.

Will report back. smile.gif
