Unlocked Voltage Controll

Hello.
I've got MSI GTX 670 PE and I'm using MSI Afterburner ( 3.0.0 Beta 9 atm. but with 2.2.3 and other versions I've got the same problem ).
The voltage controll is unlocked, I'm able to controll mem voltage, I got +745Mhz ( 3746Mhz total ) mem to work on +50mV.
Actualy this is the only unlocked voltage that works. Changing Core and Aux Voltage has no effetc ( either -100mV and +100mV, the readings are same all the time ).
Actualy I got +70Mhz ( 1320Mhz total ) set on it with +0mV but as I said voltage dosen't work.
I'm wondering how to fix it, maybe its coused by my BIOS ? I'm using 80.04.4b.00.47 which is default for my card.
Also, I'm using driver 314.22.

The vbios of most GTX670 PE are limited to 1.175v max due to Nvidia dictating that when production started. Aux voltage increase works but you can't monitor that with software.

MSI Afterburner - MSI 7850 Voltage Control

When will afterburner support voltage control for this card? We're able to unlock voltage control in options but still not able to change the voltage control in afterburner. Other mis 7970 cards can use it fine, not this msi 7850 though.

Hi again
I have been doing some further testing today, using the AMD Catalyst drivers v12.8 and MSI Afterburner v2.2.3.
THE MSI R7850 Power Edition 2GD5 card appears to have two GPU core VDDC voltage states as standard, 0.82v for 2D clocks and 1.21v for 3D clocks.
I have confirmed this using GPU-Z v0.6.4 (managed to get it to display current VDDC correctly at last) and AIDA64. For some reason , Afterburner lets it appear that you are changing the VDDC voltage (once the unlock voltage options are ticked in settings). Afterburner shows a core default VDDC of 1075mv when first installed which doesn't tally with what is actually the current 3D clock VDDC voltage of 1.21v. Even sliding this to 1.1v or 1.3v (the maximum) has no effect on the VDDC or 1.21v. The Afterburner OSD will always display what the voltage is set to on its own slider, even if sensor output still shows the actual 1.21v.
Now, this is where it gets interesting. I installed the Sapphire Trixx application which as you probably know, is similar to Afterburner. Right at the start, it was displaying the adjustable core VDDC voltage as 1.21v although the slider would only let me decrease the voltage. I believe that this is due to Trixx having a VDDC limit of 1.18v. To test Trixx, I reduced the core VDDC to 1.1v. This core voltage adjustment was successfully reflected in MSI Kombustor, AIDA 64, GPU-Z when running 3D..
Strangely, this means that the Trixx application will let me adjust the volatge on MSI Power Edition GPU core, albeit only to down volt from 1.21v where as the MSI Afterburner app does not adjust the core voltage at all, despite the fact that on the surface, it appears to work, letting you select core voltage 0.82v all the way to 1.3v. The 7850 states that it is triple overvoltage enchanced but Afterburner will not bypass the hard coded MSI BIOS voltages.

MSI R9 280X gamming bios requist to unlock voltage

if I replace the thermal paste I will lost warnty
No, you won't. Only physical damage caused in the process would. The sticker is meant to prevent from careless tinkering with the card. If you need a confirmation from your local MSI office: >>How to contact MSI.<<

I need bios with unlock voltage
There is no such. The R9 280X batches not allowing voltage adjustments by default are finally not supported for voltage adjustments. If wanting to contact MSI about it: >>How to contact MSI.<<

Reboot Window 7 and Voltage Control in Afterburner is gone (N460GTX)

after i got my MSI N460GTX HAWK card and i use MSI Afterburner 2.0.0 with Driver 260.99 i haven't tried older or newer driver but when i reboot my Windows 7 Ultimate x86 my voltage control is gone and i have to unclick them, restart Afterburner, click them restart Afterburner and i can adjust them again, i was wondering if it's Afterburner or card (Software or Hardware) problem?

Do you have it set to apply at system startup? Do you have a saved profile for it to startup on? Do both and it will apply your settings each time you cold start or warm re-start your PC.
Edit: Where I have it underlined in red, click on the little green button on the left to apply at startup.
This is not related to voltage unlock setting

Software issue for sure.

270X voltage control, AB 3.0.0 b18

Hello,
I have a brand new R9 270x Hawk running catalyst 13.12 and the newest Afterburner 3.0.0 Beta18. The Hawk claims to have triple voltage control, but I cannot seem to get Afterburner to give me the option to adjust the voltages even with voltage controls set to unlock.
Does the card need a bios update, or is there some other way to unlock the voltage controls on the 270x?

I guess no one has any insight into this topic.
In the mean time, is it possible that there is a new UEFI/GOP bios for this card?
It is R9 270X Hawk (912-V303-004)
Display device : MSI R270X HAWK on Curacao GPU
Display driver : 9.14.10.01001, Catalyst 13.12
On-board memory : 3840MB
BIOS : 015.041.000.000 (.002887)
GUID : VEN_1002&DEV_6810&SUBSYS_30331462&REV_00&BUS_1&DEV_0&FN_0
the bios rom is "150118.rom" dated 10/07/2013.
I have full access to the voltage control for the MSI R7870 TF/OC that is in crossfire with the Hawk. *The Hawk is the master card.
I'm also confused as to why the 270X is reaching 80C+ under gaming load at stock voltage/frequencies, while the 7870 with voltage cranked up to 1.256 and frequencies at 1220/1400 only reaches 56C under the same load. I thought the two cards were based on the same design, and if anything, the 270X would run cooler with the Twin Frozr IV cooler and added heat plate???
^ The reason I ask about the heat level is that the many reviews of the card I read before I purchased it had it maxing out at 60-65C under gaming load, similar to the 7870 TFIII/OC. I wonder if the fan controller on the card is not working properly.

MSI G31TM-P35 voltage control?

Hi, I'm wondering how do you up the voltage of anything on this motherboard? I thought this motherboard came with voltage control built in but I guess I was wrong. I'm trying to achieve a stable overclock with this board.

Quote
So is there a way I can shoestring voltage control from another BIOS for another motherboard with a similar chipset into a BIOS for this motherboard?
Unless you are an experienced BIOS modder with expert skills in handling assembler code the answer is likely to be "no".

It is best to remember the password, because you will need to reset the Apple TV to factory settings. Then you will need to set it up as a new device.

MSI 7950 twin fozr has no voltage control

Is this card supposed to have voltage control for the memory?
I can change the core voltage fine. Gpuz and afterburner graphs shows the correct core voltage. But when I change the memory voltage sliders and hit apply, gpuz and the afterburner graphs don't change from default 1.6
I think this card is supposed to have memory voltage control because the vrm model number allows it and afterburner is showing me the memory voltage sliders.
But I can't get it to work. Any help?

Interesting.
The reference 7950 and 7970 boards using the chl 8228 voltage controller do have memory voltage control.
The 7950 card I bought uses the 7970 ref board design with chl 8228 controller.
So the card does or should have the capability based on the hardware. But if you disabled it on the software side to differentiate your product line, that is fair and I can live with that.
But if you are saying the hardware does not support it, then I think something is not right.

Bios for KM2M, no voltage control

While there is a frequency and voltage control section in the bios, all you can change is the FSB ;( The title of the section indicates there could be that control. Is it there but disabled so we can't mess with it ? No, No, I don't want to Overclock!! :D Any hacks for this ? I also tried fuzzy logic but it just sat on the screen doing nothing no matter what i did. So all I can do is bump the FSB. I hit a wall at 2133 or so (Proc is a XP2400+)

N680GTX,N670GTX PE & Triple Voltage Control

The new afterburner that will provide for triple voltage control has been completed and is now in testing which can take several days to several weeks. While Unwinder is the main programmer, he is not the only programmer. While there is no release date as of now, rest assured that it is on its way.

What is voltage control mode in MSI Afterburner?

Hi, I have a reference GTX 970 and am wondering what the difference voltage control modes are in my afterburner settings.I have the option between reference design, standard msi. and extended msi.
Which should I use, and what's the difference between them?
Cheers,
Ben

Standard msi is for normal msi graphic card and Extended msi is for like msi Lightning kind of cards. Extended mode sometimes opens up some settings just for those cards. But basically they are the same.

Power across voltage controlled capacitor

Hi, I have the a basic enough circuit (attached). I am modellling a mechanically variable capacitor using the voltage controlled capacitor element.
I wish to measure the power across this capacitor as I am trying to calculate the electrical efficiency of the circuit, but it seems that this voltage controlled capacitor element is not really acting as an actual capacitor.
Can anyone help me on this?
Thanks
Rachel

Hi Rachel,
I looked at the circuit. The voltage controlled capacitor is not connected to a voltage source to act as a capacitor (unless you're controling it using LabVIEW which is another possibility). You need to connect a voltage source to the two bias terminals of the voltage controlled capacitor and according to the conversion ratio (how many Farads per volts) the other two terminals will act as a capacitor.
Please check the attached circuit and let me know if you need more help.

Where is voltage controlled capacitor

When I look in the component reference (in the help) I see several voltage controlled basic elements (resistor,cap,inductor). However I can't seem to find them in the database to place them in a circuit. Any ideas?

We have reported this to R&D, it was included in version 9 but is no longer in version 10. I'm attaching a version 10 file that includes two components you can copy/paste the component from there... since it is a virtual component it cannot be saved into your database, so you will need to keep this file and copy/paste the component any time you need it, until we get it fixed...
