Asus DirectCU 768 GTX460

Okay I currently have my cards set-up in afterburner at these settings:

Volts - 1.087

Core- 850

Shader- 1700

Memory- 2100

Question is can and should I push them harder?

 

[thestepster]

yeah mate those cards will do 900 core easily mate, but u might need to drop the mem to 2000 tho all 3 of my reference 768's do 900 on 1.087 my reference asus one does 930 core on its own

I get unstable machine on my first card when I clock it to 900 at 1.087. Higher voltage?

[thestepster]

ahh that while folding? stick the mem to 2000 and the core to 890 and try it again

As long as the temps are in order aka fine to deal with ,. you can go and push more voltage !

but i noticed that 900Mhz core is most of the time the hot spot on these cards ...

 

[thestepster]

yeah but to push more volts means flashing it with a custom bios and voiding the warranty

 

[TMaksimov]

Well I could just whack it up to 1.1. The coolers on these are mighty! They sure ain't quiet, though.

 

[TMaksimov]

Seems like my first card doesn't want to do anything above 850. I think I'm going to cry.

 

[thestepster]

yeah in sli they wont reach the same clocks as in single i can get 930 on max on my asus reference my inno3d's do 915 max

you gonna flash ur card to get more volts?

 

[alicarve]

my 1gb cards i have set as stock volts at 870 or 880/1760/2100 with 50% fan keeps them cool most ive pushed them to is 930/1860/2105 at 1.07v

 

[TMaksimov]

I wouldn't flash them, no. I'm too poor to do that. I can't afford to replace them.

 

[thestepster]

yeah thats how i wont flash mines either mate, strange how they dont get higher clocks

 

[AMDFTW]

i did 880/1760/2100 at 1.062mv using a 1gb versionand a single card

u dont need 1.087 for 850 but aim for 2100 mem there was something like a 200-300 PPD diff from 880 to 900

My second GPU is stable at 900 from 1.06

There's silicone lottery for you.

 

[AMDFTW]

did u run benchmarks at diff voltages todd

 

[TMaksimov]

No real difference, matey. My first gpu just wont comply over 860

 

[thestepster]

take your bottom card out mate, and try and overclock it again man

 

[AMDFTW]

No real difference, matey. My first gpu just wont comply over 860

ah right i got a 400 point diff in heaven from 1.062 to 1.087

1.062 gave me better scores

 

[TMaksimov]

Yeah but you have to consider varying run scores. It could've been just that.
