Flashed my Trifire 7970's to gigabit bios - now runs very hot. - Page 2

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


I want to see this loop!

As well as the clear to see 1260 supernova, there is an Ek360 rad in the top too. smile.gif

A 35x2 would be better for that loop....holy tubing and restriction.

Why should it?

The amount of pressure in the loop...

Temps increased because GHZ bios has much higher voltage on the cards (something like 1.26v at load?). On my reference Club3D 7970, stock voltage is 1.112v, running it now at 1.120v @ 1125/1575. Dont see any reason why you flashed the bios, since you can get the clocks manually much higher with lower voltage.

This. I ran the Ghz with such high voltage, then i actually got a higher overclock at less volts using stock bios.
