The GTX 280 runs at a stock voltage of 1.18V
Yep, 1.1875V. I was asking the EVGA Voltage Tuner max limit for GTX 280, but found it from one forum post picture. It's 1350mV.
It works using the programmable Volterra VT1165 VRM controller. If your card doesn't have it, it won't work (that's why GTX265 and GTX285 aren't listed).
You can also control the voltage using a plug-in or typing some commands in Rivatuner (without the voltage limits of course - non-Evga and HD4870/4870X2 included). Use Google, if you're interested.
DISCLAIMER: This is always on your own responsibility. I'm in no way responsible for any damage that may/may not occur after following/not following my post.
allrite, i was checking the voltages via rivatuner. i had both my cards installed. but my evga card clocks like crap and gets VERY hot.. so i removed it and tested with the gainward card alone. seemed to work changing voltage, also changed it in rivatuner. But now the app says unknown device. !?
Also my gainward seems to clock ALOT better then my evga. hitting 720 core by default. My evga does 630 stable?! wat?! Ive remouted the cooler several times still getting high temps stock..
Apparently when using SLI only the evga card was getting voltage changed, but rivatuner registrerd both cards getting voltage applied..
r these VDDC readings normal ??
1st file on default
2nd file is after applying 1.075v
1.0625v is the default under load
Does this really work good?
wow way to come on a forum and blast me because you were gonna post a hack , gossip would be untruth I posted a link to what you said, don't get mad at me, you posted it. How was this gossip you did hack the program didn't you?
It's not working very well for me. Without the tuner at 730/1500/1100 I get a crash in vantage halfway through the first test. With the v-tuner set at 1250mv's I get a strange white screen crash and sytem lockup halfway through the first test.
Easy now fellas! No need to get your undies in a bundle.
I posted a link to his thread with a hack he made for the EVGA tool and his first post here he attacks me WTF. He wrote and posted the thread what did I do. Evga is looking into it, and hes certainly has a lot more to worry about than me. Check EVGAs forum there is a anti alter clause for the use of their tool and they appear pissed. Someone linked his thread to them and it wasn't me. I for one would like to have the voltage and card restriction lifted but that not my prerogative.
I get device not recognized on my Zotac GTX295
however i have been able to use the rivetuner method without a hitch
would be nice to have a slider tho...
You have now a plugin for RivaTuner. Looks friendly.
1.) no, unfortunately the vregs are unsupported for writing new output values
2.) not as of yet, as far as my testing goes, all Bios Vmods do not work. (testing with multimeter)
NiBiToR doesn't support re-configuring VRM initialization, but you can relatively easily do it manually by hexediting VGA BIOS image:
So how does it work for ATI 4870 series cards, you mentioned a plug-in, where does one get it?
If I wanted better voltage control and I had a reference-design Radeon HD 4800, I would flash my card's BIOS with the appropriate one from ASUS, and use the i-Tracker. It lets you even control the memory voltage.
great idea, btarunr!
My only question is this, AFAIK that utility only works with the Asus Matrix card, so are you sure that that BIOS is OK for reference 1 GB cards like mine, i want to be certain of this before i flash.
iTracker ships with the MATRIX series. I don't know if it ships with the reference cards as well. If it does, you can use it. There have been several GPU utilities by ASUS that merely required the ASUS BIOS in place to run, in the past.
OK, fair enough, this is just something i have to look into if i'll be going this way.
this tool helped my clock jump on my 280 gtx but when they did performance went down figure that out.
i have the tool and patch for all brands, if anyone's keen, pm me.
i will send it to you, but i claim 0 responsibility if your silly enough to go and kill your cards ppl, after all the patch does allow up to 2v
It only works with 65nm GTX260's. Apparently they use different voltage regulators.
Heat bro. All heat.
wow, awesome, looks like exactly what we want except its locked to Asus cards
any ideas whether there is a user made patch for card compatibility? didnt take them long with the evga tool.
im not by any means asking you to supply me with it, but sharing your knowledge on whether it exists or not could be usefull.
does that work on all cards from asus including reference designs?
