Above 1.45? I wonder if ATI publishes any recommended limits for voltage. I've not seen any reports of people pushing further than that.Quote:

Wow, going to give this a shot on my 8800 later, as well as my 4850. Thanks!
Anybody tried on a 4870?

now who's going to be nice enough to tell a total n00b at programming, scripting, computer language and whatever else you ppl are experts in how to do a step by step volt increase on 4870X2 :D single and Xfire
love the hard core volt test on OBR's card there.. ... 1.6v >> over 80A ROFL crazy stuff :D >> obviously no one should really try that at home unless you've got LN2 on cards hehehehe
good work
:up::up::up::up:
working here on reference sapphire 4870 board :up:
cool that means it should work fine on your x2, dinos.
Just go start - run and type cmd. hit enter.
find directory of your rivatuner (just throw it on c: and name folder riva)
type cd c:\
type cd riva (or whatever the rivatuner folder name is)
begin to type the commands from the first post.
cheersQuote:

how does Jody create desktop shortcuts with different voltage settings...very much interested to know what :)
would be it still out of the question to try and have both hard and soft mods and then just use the hard mod to fine tune volts? would be move OVP limit down somehow if i use hardmod for just minor adjustments?
why is OVP gettin bypassed can someone tell me and OCP still stays as it is?
So why does it return as all invalid for most 4850's? :/
eyem with dinos lol
been in the cmd window , and regedit for 2 daze now alinging & tweeking my ssd ( thanks Tony :up: ) but this is squishing my noodle :rofl:
maybe in a day or so need rest
give me a couple days Dino and check the thread over at OCX. i have done up a very straight forward step-by-step there. i did for single card with a GTX 280 and multi-GPU with a pair of GTX 260s. the HD48070X2 should be the same as the multi-GPU guide.Quote:

This is what Im using for my x2. Obviously use your own values, path etc. Paste contents into notepad and save as vgpu.batQuote:

UPDATE: here is the correct formula:
(VID * 0.0125) + 0.45
Quote:
B. Calulate actual voltage by the formula: voltage = (VID * 0.0125) - 0.45
so, you could delete the second one, is useless :)
sweet fornowagain ! thats allmost a batch ;) gonna put that on notepad & see what eye can do with it later THANKS!
Almost? Looks like a batch file to me...Quote:

need my oc vitamins :D and play some games !
Yeah sorry thought it was obvious, just a simple batch file. Paste it into notepad and save it as ohmygodcantbelieveitworks.bat

ah ok :ROTF::DQuote:

Sweet!!! :D
Thanks for the bat script, fornowagain !
when you execute this .bat file are you saying that you will get a choice of voltage with selection criteria or do you have to edit the file to get the required voltage set automatically?
Yes, you can choose Voltage. If you need more voltage than 1.4V you have to edit.Quote:

Any luck in 3dmark06 at those clocks?Quote:

Assuming the install path is the same, same OS etc. I'd always recommend working through the calcs to make sure you understand the values and that they're correct. If its a different card just modify it to suit.Quote:

if you are stuggling to see the same clocks on it as others dont be surprised
