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.

What version Afterburner have you been using?
Perhaps you should also check with the Afterburner support forum.
http://forums.guru3d.com/forumdisplay.php?f=55
sigh they allways give the same boring response...im not stupid ofcourse iv got the latest drivers feel pretty ripped off by msi atm u cant release a product without the software..... its false advertising.......box say supports tripple overvoltage......but it doesnt yay......
I am the moderator at the MSI "User to User" forum that gave that reply to him. I am a user of MSI products as are all of the mods over there and none of us are paid by nor employed by MSI. MSI does not write the code for Afterburner as you all should know and for him to come here bashing MSI & their support forum is uncalled for. I respectfully request that this MSI bashing post of his be removed as well as my reply.

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.

MSI 785GTM-E45 BIOS CPU fan voltage control

Hello MSI gurus,
I've replaced the MB in an older HP media center with the MSI 785GTM-E45 running BIOS V8.8 out of the box.
CPU = Athlon 64 X2 4200+
My problem is the stock CPU fan has a 3 pin connection (voltage controlled) and is running at 100% speed all the time. From what I've read on the forums there are a number of people that have this issue (with other MBs with 4 pin cpu fan headers) and don't want to switch to a 4 pin CPU fan (PWM controlled). I am in the same situation.
I am hoping that there is a BIOS for this board that has an option to switch to or enable voltage control on the CPU fan header.
I have tried enabling the CPU smart fan target but no matter what settings I chose the fan remains at 100%. The H/W monitor of the MB indicates a CPU temperature (33C) well below the target (tried all options from 40C to 60C in 5C increments).
I have tried MSI's dual core center and it had no effect on the fan speed.
I have tried the 3rd party freeware SpeedFan and if had no effect on the fan speed.
I am not able to check if I have the latest BIOS or even find changelogs for existing BIOS verions because MSI seems to only direct BIOS downloads for this product to the Live update application. I have installed the live update program and it indicated V8.8 was the most recent veriosn of the BIOS for this board, although I have seen posts indicating the Live Update application is not to be trusted.
Dual core center, SpeedFan, and Live Update have all now been uninstalled.
I know the fan I'm using will change speed because I can connect a 3 pin fan controller and manually dial down the speed.
I know the BIOS can read the fan speed becase it correctly shows the RPM changes when I use the hardware fan controller.
Can anyone direct me to a BIOS version for this board (or some secret keystroke) that enables automated 3 pin voltage control on the CPU fan header?
Thanks in advance for your time.

For those who are interested I received the following answer from MSI technical support. Personally I find this to be a flaw in this board's design. I chose this MB to replace a dead MB in a HP media center for a friend. If I was buying this board for myself I likely would be using it as a HTPC because of the mATX form factor, HDMI on board, and backward compatibility for CPUs. However, due to the added cost of purchasing a new heat sink and fan I would be RMAing if I had bought it for myself. Considering many of the top performing after market coolers still come with a 3 pin fan it was a poor decision for MSI to not include support for automatic speed control of a 3 pin voltage controlled fan.

Dear Sir/Madam,
Thanks for contacting msi technical support team!
We are sorry that because of the circuit designs,we could not add cpu smart function for 3 pin's connector fan in the BIOS. The difference between 3pins and 4pins is that the second has a temperature controller but the first does not.We would suggest you utilize a 4-pin CPU Fan in order to control the CPU Fan speed.
Sorry for any inconvenience caused you!
Best regards,

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.

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.

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".

MSI Z97 XPower AC - 4 pin fan headers - PWM or voltage control?

The instruction manual states that the 2 CPU 4-pin fan headers are PWM control rather then voltage control. The rest of the 4-pin fan headers say "NC" on the fourth pin. Does this mean that the fourth pin has "No connection" and that they use voltage control of the fan's RPM? If so, this seems like a big oversight not to have PWM control on all the fans like another well known motherboard manufacturer.
My second question is... does this motherboard control the fan speed by using variable resistance to the fan headers or produce variable voltage? The following FAQ copied from Noctua's website states that there is a difference and the fans may not operate properly if used with resistance based fan control rather then the MB actually producing variable voltage.
Can Noctua industrialPPC fans be used with fan controllers and resistor cables (Low-Noise Adaptors)?
Noctua recommends not to use industrialPPC fans with common PC fan controllers, resistor cables (Low-Noise Adaptors) or other devices such as potentiometers that work by applying (variable) resistance rather than actually generating different voltages such as a laboratory power supply does. Due to the higher internal resistance of the industrialPPC fans’ three phase motor, applying additional resistance will cause the fans not to start (e.g. with Low-Noise Adaptors) or to have high starting speeds (e.g. with most common PC fan controllers). Please note that the industrialPPC fans feature starting voltages between 5.5V and 6V and can be run at these voltages on devices such as laboratory power supplies or mainboard fan controllers which actually generate lower voltages rather than applying resistance. Noctua thus recommends to use either PWM or voltage based mainboard fan control or laboratory/industrial power supplies for controlling the speed of industrialPPC fans.

Indeed only CPUfan 1 + 2 are PWM controlled according to the manual. Also yes, NC means not connected on the other headers what is why speed control is shown among the three pins left. That of course means that voltage control is used for these headers.
Controlling speed with resistor between power (12v) and fan is an aftermarket solution while on mainboards the voltage applied to the header is already of the voltage needed for control (generating lower voltages than 12v). So also in case of your board the lower voltage is generated and not lowered later on.

MSI 7850 OC

Hello,
i have the standard MSI 7850 OC 1 GB
I want to undervolt it for my htpc!
But sadly MSI afterburner gives me a bluescreen every time i touch the voltage control no matter if I overvolt or undervolt even just changing it by +-10mv gives me a bluescreen.
Strangley enough Sapphrie TRIXX tool can overvolt just fine (gpuz confirmed) BUT TRIXX doesnt let me undervolt at all and the voltage hops back to factory setting each time i undervolt even by -10mv and yes I tried to lower core and mem clock with it too.
What really bugs me tho is that MSI own tool AFTERBRUNER seems to work worse for their OWN gpu !!!
But once again, I dont care the means but I need to UNDERVOLT my MSI gpu somehow.
Any help is greatly appreciated!

No, all MSI 7850s besides Power Edition aren't meant to have voltage control. Trixx although offers overvolting (which is by far not recommended) but as it won't offer undervolting such is not possible.

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?

Quote from: Henry on 27-November-10, 06:47:20
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.

MSI 280X Voltage Locked - Help Please

hi guys
I purchased an MSI 280X Gaming OC GFX and would like to undervolt it
I read on forums to try this bios: techpowerup.com/vgabios/146769/msi-r9280x-3072-131009.html
which i did with ATIflash in DOS, i switched to position 2 on the small switch (switch left direction to back of case), it flashed and said successful but when i boot its just a black screen and no output
when i put the switch back to position 1 (switch right direction to front of case) it works fine with the original bios (015.042.000.003.000000 )
any ideas why i cant boot from switch position 2 with an older bios? is my card faulty?
my card s/n is: 602-v277-44sb13121xxxx
my aim is to flash an older bios so i can get voltage control in After Burner
many thanks!

Don't know. Ask MSI: >>How to contact MSI.<<
There is nother vbios supporting more features than current vbios TV277MH.380 you provided. To have backup simply flash it on the bricked one. If you can boot your system with onboard/integrated gpu or you have an old spare vga for display boot with the R9 280x switched to the bricked vbios and flash the vbios with your saved one.
That's great. Do you a link to this other vbios please?

MSI 7850 Twin Frozer issue

Can anyone help me with my current issue.
My system runs perfectly and will stay up with no issues if I do not run any games. However if I run any games the graphics card seems to stop responding correctly, system does not shut down so no errors in the Event logs. Need to restart machine manually before able to view screen correctly again.
Sometimes the system may run for a couple days without causing any issues while playing games but once it does it normal happens after about 10-15 mins playing a game.
Screen just goes into either a multicoloured mode or one straight colour. Which is annoying.
I have latest ATI drivers installed - reinstalled OS. Even disabled the HDMI sound within Computer management which has helped a bit but not resolved issue. I have paid a fair bit of cash for this card and do not really want to buy another card. I also do not have a second machine I can move card to or different Video card to try in my system.
All help would be gratefully received.
System Setup:
Main Board: Asus P9X79
CPU: i7 3820 @ 3.60GHz (8CPUs)
Video: MSI 7850 2GB Twin Frozer
Memory: 32GB (a little overkill)
PSU: Toughpower XT 875W
HDD: System (OCZ Vortex 120); 2 x 1TB Western Digital
OS: Windows 7 Ultimate

Hi Svet,
No I don't have any OC applied.
And I dont have access to another PC to try.
The issue is very hit and miss. Just seems to be very strange. System still seems to be running in the background just unable to see the screen. Running games in 32 bit seems to work for a while then will do the same thing. At the moment the system has been stable for the last 4 days.

MSI's own Control Center hard crashes my comp (P67A-GD65)

So I just got a P67A-GD65 B3 board, with an i5-2500K and I got it all set up and put together. The thing runs great, quiet, cool, etc. I'm currently at stock speeds and settings. However, I did NOT use the MSI CD to install drivers. Instead, I used the website so I had the latest versions of all these drivers. Anyways, I installed pretty much everything but the TPM Modules and RAID tools.
So, when I pull up the Control Center, the main screen displays fine. However, as soon as I click the Cooling tab to check temperatures, the computer locks up hard and the sound emits a strange audible buzz through the speakers. I have no clue why this is happening, and furthermore, I'm disappointed this is happening on a very stock build. I literally installed the components, installed Win7 x64, installed the drivers, then tried to check the temps. That's it.
I have successfully used SpeedFan to check my temps, so I know it's not some issue with probing the sensors. Does anyone else have this problem, or know of a solution? I think it's kind of silly that MSI's own control center for their mobo's crashes the computer.
My specs:
P67A-GD65 (B3)
i5-2500K @ stock 3.3ghz
CoolerMaster 212+ HSF cooler
8GB (2x4) Corsair Vengeance DDR3 PC1600
XFX HD695X-ZDDC 6950 1gb vid card (the XXX turbo edition)
Crucial C300 64GB SATA SSD (boot drive)
Samsung Spinpoint 1TB SATA Drive (storage)
Corsair TX650 v2 PSU

Seriously, this is kind of ridiculous. MSI needs to get their stuff straight. Others are having this same problem.
I trust you did report this to MSI technical as per earlier responses in this post. Posting opinions out of frustration does not add value, nor does it assist in fixing the problem. This forum's prime objective is to gather factual information in an attempt to anlayse the problem and then employ the user community to post potential solutions. >>Please read and comply with the Forum Rules.<<
If others are having the same problem, then they also need to report this to MSI technical, being as comprehensive as possible. As I mentioned before, it seems a 64bit OS symptom.
