AMD - How To Overclock The Official Way Using Afterburner + Step By Step Overclocking Guide + Comple

[LtMatt]

Then you card would have been throttling to stay within its power limit. I guess you didn't read all of the guide.

 

[LtMatt]

Use CCC instead of afterburner then to max the power limit at +50%. Afterburner doesn't fully support 280X cards yet.

 

[LtMatt]

Maybe he didnt do the /xcl trick after new driver install?

All that does is expand the core and memory overclock limits. Its no longer needed as you can do all that from within afterburner settings.

 

[LtMatt]

Games are always more demanding than crappy synthetic benchmarks. If you're bench stable at a specific clock speed and voltage setting, whack the voltage up two more notches then test some games. If i was you id put your memory back down to 1500 until you get your core 100% stable. Memory past 1600 on 7970 gives diminishing returns.

 

[LtMatt]

Alright bud, will try it now.

What's the maximum safe voltage on the vanilla 7970's? I have mine at 1200mV, 20% power limit.

As long as you can keep it cool enough 1.25v is easily safe. Up to 1.3v is safe really but temps might become an issue at that high on air.

 

[LtMatt]

Sounds like you might need to disable on board gpu in the bios mate.

 

[LtMatt]

Matt - Am I reading this right, I need to untick the enable graphic overdrive in CCC?

TIA

If you've not touched it, it won't be unlocked. So assuming this is a fresh driver install, leave it alone. If you've used it previously, lock it and use afterburner for overclocking.

 

[LtMatt]

Leave CCC alone, do not unlock overdrive. Use afterburner for overclocking.

The news every one wanted to hear!! Msi Afterburner Overlay to get 64bit support, will work with Battlefield 4!! OMGWTFBBQ

On 64-bit RTSS:

I'm currently analyzing the way which can satisfy most of us. I'm going to offer MSI to invest month of development time on 64-bit server development then make it exclusively available for MSI Afterburner OSD display only. For MSI it looks like much more attractive selling point, because MSI's OSD takes an advantage and no RT-based products I develop for other vendors will have support for it. For me it means that I can safely cancel all other tasks and focus on this task without loosing my income during development time. And for you it means that 64-bit OSD will be available least in Afterburner.

 

[LtMatt]

Fantastic post. Is it still relevant for my 7950? Or has anything changed since then?

Still relevant.

Is my AMD hd 7970 voltage locked?Can't control voltage,and I tick allow voltage control
I thought gigabyte,xfx,sapphire... locked voltage control on theirs cards.
Did amd lock their cards as well later in production cycle?
Will I need to flash bios to gain control on voltage?
ta

What brand is it?

amd hd 7970 925mhz 1375mhz

Show me a picture of the card.

 

[LtMatt]

Try using the latest version of MSI Afterburner beta 17. That should give you voltage control. No need to update the bios on your card, just use the stock bios.

[LtMatt]

I will check that now mate.
I red that ghz bios operates on lower voltage and gives higher clocks

If you could not unlock voltage control then maybe you were using a old version of afterburner. Ghz edition bios operates on higher voltage and higher clocks. Its not worth it though. Just manually overclock yourself and increase voltage as needed.

 

[LtMatt]

Sill now luck
I tick allow voltage control,and still can't do it.
I gain extend official oc limits,before I could only set 1125 maks. and 1575.
Am I doing something wrong or this card is voltage locked,and the only way to unlocked it, is to flash bios?

Show me a screenshot of afterburner and gpu-z plox. You have a reference card so it should not be voltage locked, as far as i can tell anyway.

 

[LtMatt]

Copy these settings. You might need to restart afterburner. If its still locked after that then im out of ideas im afraid.

 

[LtMatt]

How bizarre. You can leave unofficial overclocking mode disabled btw. Don't know if that will make any difference. At this stage all i can suggest is to try Trixxx instead.

 

[LtMatt]

Where is the best place to download Trixxx?(without other crappy programs along the way?)
Will do in the evening,now I got other stuff to do.
Cheers for your help Matt
Already downloaded Trixxx,and IT'S WORKING!

Good to hear. I'm amazed that afterburner does not work tbh.

 

[LtMatt]

Yeah it's a pity.
I'm totally new to Trixx,can I display temps,clocks,during gaming(left to corner) or I need download other program to monitor that?
Trixxx only control core voltage?,what about memory voltage?

Trixxx can't display OSD, you'll need to use afterburner for that. Not sure about the memory voltage on trixxx, should be able to if you can scroll down. Very little to be gained from the memory though.

 

[LtMatt]

So trixxx and msi afertburner working alongside together,won't cos any interference?
My values in trixxx for vddc 1,2V - gpu-z=1,156V
1,212V - 1,184V
Is that normal? As far as I now 1,25V is safe for this card,but I won't achieve this voltage cos trixx got maks. vddc to 1,3V but gpu-z readings are much smaller?

What is the best stability test for OC?
I'm running sleeping dogs on highest possible setting (1920x1200)?

Won't do so long as you don't touch clocks/fan speeds in afterburner. Yes thats normal, its vdroop. On reference cooling id stick to 1.2v or lower.

 

[LtMatt]

trixx 1,25V gpuz 1,209 for 1175mhz and 1600mhz.
Pass benchmark in tomb raider min 42,8,maks.68,1,ave.54,3
I'm going to deep her under water soon,just checking if she is worthy to keep her
How to use snipping tool after finish benchmark it tomb raider?or are you using different program for that,Would like to post score in the thread.

I use afterburners screenshot function.
