Im almost certain ive made a mistake, as my temps havnt changed either :rolleyes:

.

EDIT: just tidied it up a bit, seems to be at 1.5v now.

loltim · 1 Apr 2006 at 18:24

You might be lucky and get 700 with 1.5v, I couldn't but you may, what you aiming for?

pinkacidbootson · 2 Apr 2006 at 00:53

Im aiming for higher than you

but yeah im hoping for 700, as 1.4v gave me 660, it doesnt seem much of a stretch.

loltim · 2 Apr 2006 at 00:57

So what did 1.5v get ya?

pinkacidbootson · 2 Apr 2006 at 01:12

Nothing

its just the same as 1.4 again :confused:

. I dont get what ive done wrong. The paint has definatly been put on correctly, ive redone it and looked at it from every angle and it looks right. Any ideas?

Do you think linking the second D508 and the first D511 will have the same effect? That might be easier

loltim · 2 Apr 2006 at 02:05

I wouldn't like to say really, I just know there were definite gains going from 1.4v to 1.5v with my card.

My core maxes out at 684 - any more then i get freezes, no corruption or anything, its a bit annoying really.

Memory seems good - im at 1800 on the memory, the nvidia tool says its not stable above that, but im sure it probably is.

Is everyone using coolbits?

Is there a rivatuner that supports the 7900 series yet?

I have read that there isn't.

what about powerstrip ?

is anyone using this?

pinkacidbootson · 2 Apr 2006 at 12:25

I used coolbits at first then moved to ATI tool when i needed to go higher

Cyber-Mav · 2 Apr 2006 at 12:34

whoa a 684mhz core and 1.8ghz ram!!! that must have some serious speed behind it! :eek:

vocch · 2 Apr 2006 at 17:39

Well finally hit 10k

What speed core/mem?

vocch · 2 Apr 2006 at 17:48

Speed in sig.

Bookime Wood · 2 Apr 2006 at 17:53

Do you have any tweak tips for 05?

vocch · 2 Apr 2006 at 18:10

What i do is make sure that it's allready set at high performance turned off the aa/af + vsync....set the overclock profile in ati tool to start when it detects 3d....so on a restart it's just a matter of starting 3d06...set priority to high kill what you can.... run 06 and overclock starts on it's own....supose i could have got some more points if i killed my security centre + explorer.

Can someone (eg Tim) please take a photo of their 1.5v/1.55v mod, i really cant see whats wrong with mine!

loltim · 3 Apr 2006 at 01:17

Thats 1.5v, never got a pic of 1.55v and its too dark now to take a photo but its basically as the drawings say.

pinkacidbootson · 3 Apr 2006 at 17:28

That is exactly what mine looks like. Im gona redo it one more time then if it doesnt work im sticking with 1.4. Thanx for the photo

loltim · 3 Apr 2006 at 17:35

Heres a more recent pic now we've got some daylight, no problems at all in the 2 days I've ran it at 1.55v/710MHz.

Mr Mister · 4 Apr 2006 at 12:56

what do you think the max safe voltage would be ok to use with a zalman vf700 on it?
