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

I expect its just heaven displaying the wrong clocks. Ignore it. :)

I wasn't pressing "Enter" after entering the numbers into Afterburner :D

Tried the clock speeds in the example image in the main post, Heaven just showed a black screen whilst the music played in the background and had to reboot. I'll have a look around and see what others are using as their cloicks.

Thanks for the guide!

Yes you need to click apply in afterburner. :D

If i was you i would start at default clocks and default voltage. Focus on the core first then the memory. Bump the core by 25mhz and try to complete one benchmark run of unigine heaven. If you complete ok without a crash, black screen, driver reset then bump the core another 25mhz and rinse and repeat. If you get a crash or whatever restart your pc first (otherwise you lose performance) then bump the voltage a notch and run the test again. Will take a while but its a good way to find a stable overclock. Once you have it stable test it on todays current dx11 games. Farcry 3, sleeping dogs, battlefield 3 are good games to push your gpu hard. You might find you need an extra notch of voltage to be fully game stable.

Cheers. Is it worth throwing the power limit straight up to +20 to start with?
 
Weird.

Before I did the guide, I did a Heaven benchmark with stock speeds:

925/1250 giving me 45.4fps and a score of 1143.

Just completed a Heaven run on 1000/1350 and got 41.3fps and a score of 1041.

Worse performance than stock somehow haha!

Have you restarted your pc after the driver crash?

Yep. I think my Steam friends might be getting annoyed and me signing in every 2 mins :D

Just ran 1025/1350 and got 47.4fps and score of 1194 so an extra 2 fps compared to my pre-guide run on stock 925/1250. Extra 6c in temps too.

Maybe I had something else running that was helping performance somehow before.

Possibly. Increase your fan profile if needed. Try to keep temps below 75c once you get up past 1050 core.
 
Hey all,

today I overclocked a bit more. Took my 7970 to,

voltage 1263
Core 1235
Memory 1670

However in my benchmark tests my scores have gone down slightly from the previos overclock of,

voltage 1250
Core 1200
Memory 1600

Now should I increase voltage as I am only running at 67C max on the card or have I took the overclock a bit too far and need to lower it slightly?

Probably a slightly unstable core. Try to increase the voltage a bit. If it makes no difference then you need to check the memory.

Embarrassingly it was the fact that in CCC somehow adaptive multisampling was on instead of multisampling.


On this overclock once I get to 1240 on the core I start getting artifacts in benchmarks, even adding more voltage doesn't help. Does this mean I am at the limit of the core overclock?

Also with the memory overclock what are the signs of hitting your limit?

Yes. You've either reached the maximum your card can do, or you have reached the maximum your card can do before rendering errors occur with your cooling solution. If you can improve your cooling or can keep the gpu cooler you might be able to go further.

Overclocking the memory too much will result in worse performance or a coloured stripy screen when your gpu crashes. 3DMARK is a good benchmark to use to overclock memory as when your scores get considerably worse you know you've reached your limit.
 
Good news for all who can't get XCL/Unofficialoverclocking working!
: 3.0.0 AB
Sure. 3.0.0 beta is ready and it will be used in upcoming Guru3D review.
Changes list includes:

• Ported to new VC++ compiler, new core and skin engine libraries with better extendibility
• Added NVIDIA GPU Boost 2.0 technology support for NVIDIA GeForce GTX Titan graphics cards:
o Added slider for temperature limit adjustment
o Added option for linked power limit and temperature limit adjustment
o Added option for temperature limit prioritizing
o Added maximum voltage adjustment
• Improved skin engine, now skinned slider controls support curved paths defined by alpha channel. Skin format reference guide has been updated to v1.6 to document new slider types support
• Fixed single tray icon mode functionality under Windows 8
• Improved single tray icon mode handling. It is no longer necessary to restart application when toggling single tray icon mode
• Now unofficial overclocking mode and official clock limits extension command line switch (XCL) for AMD graphics cards are accessible via GUI in “General” tab in “AMD compatibility properties” section
• Now MSI Afterburner displays voltage regulator model and location information in “i” window
• MSI On-Screen Display server has been upgraded to version 5.0.0. New version gives you the following improvements:
o Ported to new VC++ compiler, new core and skin engine libraries with better extendibility

Thanks. Some interesting changes there. :)

Looking forward to when it gets released.

Hi continued

my asic is 72.6%

just noticed you're guide must admit i didn't do all that should i?

Yes, certainly won't hurt. :)

What you need to do is start at stock voltage and a stable core clock and work your way up from there. Leave memory at stock for the moment. Use unigine valley to test core stability. Complete one benchmarking run of said benchmark. (run it then press f9) If you complete the test bump the core 10mhz and run the test again. If you crash, black screen, or get an error restart your pc then bump the voltage one notch and run the test again. Make small steps, take your time. Its time consuming but these cards can be sensitive and it takes time to get the most from it.

You also need to run out temps limiting your overclock so run the fan at close to full speed. 75c or higher can cause problems when overclocking.

Update i can only get to 1135core stock volts.
After that it locks up in benchmark
How much voltage to increse to from 1175?
1180 maybe is that to little or much?

my temps stay between 62 and 65

Calm yourself young padawan. Rome was not built in a day and neither was a Tahiti card clocking to 1175 in one fell swoop. Think of me as a young, more virile version of Mr Miyagi. Sure I'll have you washing my cars and cleaning my soiled y fronts but at the end of the day you'll be getting the most from your card.

Ok so you can do 1135 on stock volts huh? Well my card does 1125 maximum on stock volts and i can go up to 1325 and beyond if i get my voltages right and keep my temps low.

So, run a benchmark run of Unigine at 1125 stock voltage. If you complete then knock the speed up 10mhz and rinse and repeat as i posted above.

Do not make large jumps, you need to be patient and take your time. You're on air cooling so getting optimum voltage is essential if you want to clock well. You can't just ramp it up and assume it will be stable.
 
I fear the Mr Miyagi comment might well have scared him off. :(

Matt, can you help me along the way please? This is giving me a headache doing it on my own with no guidance. :(

If you can help me get my card running quicker than three 7970's in CF then you can have the G1 for free ;)
