Hi Matt thanks for that, think i am behind on the driver side of things I have never used CAPS before either so not 100% sure how they work. The thing is the games i play GTA Sleeping Dogs and BF3 all seem to run well and i was worried that updating drivers might cause some issues. Im sure if i update everything will be fine i just hate changing things that work if you see what i mean

As for my card its the MSI 7850, without doubt this best card i have ever had really impressed with it. I just know i can get a little more than 1050/1200 out of it

Nice thats a lovely little card. Clock the mofo out of it. Seeing as youre on the 7xxx series card you MUST upgrade your drivers to 12.8. They offer huge performance improvements in a ton of games, especially bf3.

Caps are easy to install, just install them after you install the driver before you restart your pc. When upgrading caps uninstall them, restart and install the new ones.

Thanks for this guide kind Sir,

But I just can't get the Voltage unlock, even when ticking the unlock is my last step after adding the dll files etc. I was an Nvidia user before and tried with and without the dll files.

Shame as i prefer AB over the Asus GPU Tweak.

Once I run the patch should I restart it as prompted, only step i haven't taken, as I've followed by the word.

Cheers though

You can't unlock voltage control in afterburner? :confused:

That's the easy part.

Maybe voltage control is locked for your card?

Here's what i see.

I have went through all stages, ticked unlock but still greyed out.

I can change the voltage on other programs upto 1225mV

Which version of msi afterburner are you using?

If you use the unofficial overclocking method will that let you unlock voltage?

I'm stumped tbh. Not seen anyone have problems unlocking voltage on afterburner before as its a default feature. (providing your card has unlocked voltage)

2.2.3 is the version im using, I used to be able to get voltage unlock on my old 460, only time I have seen this myself (apart form now) was when my mate got his 570 twin frozr and after a year it still doesn't allow voltage unlock.

Been tinkering about with the unofficial method this evening and no joy, may just have to use the asus software.

Which card have you got?

Maybe its a known issue with afterburner?

IRLeetly · 24 Aug 2012 at 21:41

Its a MSI 7850 Twin Frozr III OC.

I think someone else in this thread has had luck with the very same card.

liamcrane · 24 Aug 2012 at 21:47

What is a max safe voltage you can put through a 7850 any ideas? I dont wanna go anymore than 1.25v if im honest

Hmm, no idea then tbh unless that 7850 owner comes forward and shares his oats.

I think all 7xxx cards have a limit of 0.125mv which you can add before over current protection kicks in and the gpu shuts down requiring a restart.

I know this is the case with 7970's as i can make it kick in when using OCCT GPU 4.3.

Uisng this calculation my stock volts are 1.112. Plus 0.125mv = 1.234. So, if i exceed that voltage in afterburner then there is a chance of OCP kicking in.

Think it was Lazdaa

I maybe wrong, I have read a shed load of 7850 material on this forum this week

liamcrane · 24 Aug 2012 at 21:58

Thanks for that Matt much appreciated

I have the exact same card as you mate, i am gonna give Matts suggestion in this thread ago so i'll let you know how i get on. I have only just installed AB version 2.2.3 was using 2.1 for ages

Im still running the 12.3 drivers as well so i'll try with these first

Find out your stock voltage, add 0.125mv and you should be good up to that. Maybe leave a little bit of leeway.

I can trigger OCP in my 7970 @ 1.2volts which is a fair bit under my limit but these power virus software really push the cards beyond normal levels. :eek:

Cheers mate, i'll give it one more bash also, then i shall weep myself to sleep until GW2 opens tomorrow.

On the Afterburner version i received on disc with my MSI 7950, i didn't have access to voltage. I today redownloaded latest version from the link below and i am now able to change the core voltage: http://event.msi.com/vga/afterburner/download.htm

Exact same problem, followed all the steps as outlined as well. Ah well

Its because afterburner voltage control is not supported in your card yet. Try the latest beta version of afterburner, if that doesn't work then you need to wait for it to be updated.

Yeah, I am just using the CCC Overdrive now. It seems to be cruising along happily at 1100 core, 1300 Memory. This will do just fine for now
