Sapphire HD 7870 XT based on AMD Tahiti LE chip - Page 13

post #121 of 316
For sure since you running the 7870 125Mhz more and you use 3770k at higher speeds too.
Big difference in physics score too if you check it.

Good score btw! thumb.gif

Thank you guys. I can do 1200/1500 with 10-15% now!

Yeah,

the buzzing is annoying, specifically when I open browsers/scroll them on the system i stuck this card in, I have it on my main system, but it's faded to the point where I dont notice it.

Maybe i need to find a program with a high FPS Rendering rate on the menu and let it go.

i know i have 1200/1500 stable, Also have a 3rd fan on the floor of the case blowing air up on it, and a VERY Aggressive Fan profile (system uses noise cancelling headphones, so some dustbuster noise is nothing).

however temps still got pretty high, and will only go higher in the summer.

So in the winter I'll run the OC, in the summer I'll drop them, I will force a 1Ghz overclock for most of the year though.

I guarantee that this is the same original problem I had. You have to contact sapphire to get there new Vbios and flash your PC from dos. God knows why they don't advertise that the original bios is FUBAR but they don't. Anyways it fixed that problem for me.
post #126 of 316
Yeah I've done that, but it crashes mid game every time. It simply WILL NOT hit 1200 MHZ regardless of what voltage I apply, and whether or not I apply 0 % or 20 % power to the card. I've tried every possible combination, and tried with Msi afterburner, Trixx, Asus GPU tweak, and overdrive, which by the way is useless. I can't squeeze more then 6000 score out of the card.

I'm running it with a phenom II x4 960T on a corsair cx400 and have had no problems thus far. Now I certainly am not going to overclock the card...but I've experienced no problems thus far.

Try this:
Wwithout increasing the voltage and by using Trixx set:
Core to 1200
Memory stock 1500
Voltage to 1250
Power board +15

Apply and test.

Force constant voltage disabled.
