MSI Afterburner issue

[xnax2802]

So I finally decided to venture into the world of GPU oveclocking, and do a simple overclock with MSI Afterburner on my aging MSI 660 ti Power Edition. After way too much fiddling around with the core clock and voltage slider, I realised that the monitored GPU voltage during stress testing stayed at 1.175V no matter what I did to the voltage slider. Am I a noob and not looking at the right thing or is the voltage locked on my card?

Afterburner doesn't seem to allow you to change voltages on default, however adding the following lines to the top of C:\Program Files (x86)\MSI Afterburner\Profiles\VEN[somethng].cfg has done the trick for me before.

[Settings] 
VDDC_Generic_Detection = 1 
VDDC_uP6262_Detection = 0

Did you unlock voltage control in Afterburner? IIRC It's an option to prevent people accidentally over volting their cards.

I did, but all it seemingly did was unlocking a useless slider

In this case u have to use bios editor.

That would be the date when OP joined the forums. The date that the thread was posted on is visible just above OP's avatar. This thread isn't that old at all, especially compared to some that you have recently replied to, so please keep an eye on that date, thanks

Now back on topic fellas!

I, OP, can confirm that no necroposting was done in this thread

I also appreciate the help given in this thread, but messing with the BIOS isn't something I'm interested in this close to upgrading my GPU. It just doesn't seem to justify the effort as of now.

Hi,

I ran into the same situation when over clocking my GTX680's originally. Afterburner, not matter what settings you use, simply cannot influence the locked voltage of certain GPU's.

In order to overcome this I had to basically flash the BIOS on both GPU's with a custom one allowing the cards to go beyond their default hard voltage limits.

In the end I went from the default max of 1.175v to 1.2v - after doing this my GPU's automatically boosted to my max 100% stable OC of 1.2ghz. The only thing I had to do in Afterburner was increase the power limit to 110% otherwise the cards would often throttle due to regularly going over 100% TDP. Possibly, by allowing say 115% over TDP they might boost higher, but I set myself a "safe" limited of +10% for my own peace of mind.

Note that I'm water cooled so temps were never an issue, but even a chilly GPU can be killed by too much voltage, so do take care.

I used a utility suite called KGB, check out the (external link) thread here It'll either help you understand what you're getting yourself into, or scare you off it completely - BOTH are good

Scoob.

Actually that would be about the best time to do it. Or right when you get your new card flash the old one. That way you can learn and not throw that new gpu in the trash!!
