Ahhhh wait for my Gigabyte 6970 arrived

[Falkentyne]

After switching from a P5wdh to a P67 UD5 board, my videocard overclock went way up. (it previously wouldn't even do 945 mhz at 1.25v unless the fan was blasting, now its going 950 at 1.225 and 60%, since I was flashed there before the system upgrade). I'll revert to stock later to see just how far the OC increased (old stock max was 920), and then see about going past ccc limits. I also had GSOD at 1450 RAM on the old board. With this new board, no GSOD...

Hi,

Have I a poor sample here. I can just do 920@1450 with out crach in 3DMark11. Memory looks fine but the gpu???
All over 920 make a crash. It doesn´t matter if I change "power settings" to +20 in ccc either.

Maximum stable overclock, using 1.30v max in afterburner and 100% fan speed.

Tested using atitool. I found when there's no OC programs running in background it allows gpu usage to go up to 98-100%. It finds errors quite quickly, more than gputool i think.

ATITool running for 22 minutes




ATITool stopped




3DMark 11




Vantage




Crysis




Heaven




I let heaven loop before starting the benchmark, nice minimum FPS

1020MHz on the core artifacts pretty much straight away in ATITool, but it can run benchmarks.

Modded Sapphire 6950 with 6970 bios.

It won't go higher than 920/1425 at stock voltage though, higher and it can't go through 3dmark 11.

[Vega]

Can any one explane for me how to unlock msi ab so I can oc further than 950MHz on gpu?
It is a noob qust. but wtf!!
I use version 2.1.0 beta 7. Do I have to uninstall ccc or what?

Update: I solved it!
Thx any way..

[Mydog]

This is my max OC so far.
2x Sapphire 6970 with Asus bios watercooled. Got lots of OC headroom on the CPU's but just testing OC on the 6970's.

[Vega]

So how do you do when you use msi ab? I can easily do 950@1450 with 1.2V but everything over 950 crash 3dmark11. Vcore does not matter. I have tryed up to 1.3V.
Do you disable ccc?.....if how?

Thanks in advance.

I flashed my cards to Asus bios and used Smartdoctor to enable more OC headroom. I shut down Smartdoctor when I use Afterburner thats all.

[-Sweeper_]

cant go over 950mhz in my XFX HD6970, what software are you guys using?

do i need to flash another bios?

[Mydog]

I would Flash the cards with Asus bios and use Asus Smartdoctor to enable higher OC

[Vega]

Can the bios version effect the gpu limit?

[Mydog]

Not sure I understan your question, if you mean the max OC limt fo your card I dont think so but if you mean OCing over 950/1450 then i Think the Asus bios combined with Asus SmartDoctor is the best combo at the moment.

Improved a little on my 3DMark11 and Hwbot Heaven DX11 scores

[Vega]

Very nice score! Impressive memory oc!!

[skuldarin]

dump the ASUS smartdoc and use MSI AB. smartdoc actually limits the OC potential, i've done the comparing to proove it. though my card is an HD5970, i still get higher clocks and better numbers with MSI AB.

Sry guys for asking but i have problems with setting the clock on my XFX6970 running in CF over CCC frequencies (950/1450) in Afterburner beta7. I have flashed both cards to Asus bios and enabled unofficial overclocking mode in Msi Afterburner cfg file. What am i missing here? I have the cards watercooled and would like to push them a little further than 1050Mhz with Trixx on 1.175V (if i use AB for setting the voltage Pc freezes)

Have you done this:

To enable unofficial overclocking in this version it is necessary to:

Set UnofficialOverclockingEULA field to the following text: I confirm that I am aware of unofficial overclocking limitations and fully understand that MSI will not provide me any support on it
Set UnofficialOverclockingMode to 1 to keep PowerPlay active (may not work on old ASICs), 2 to traditionally disable PowerPlay or to 0 to temporary disable unofficial overclocking path

[Shark-357]

Great thanks for info

set 0,1, or 2 still limited 950/1450 with asus 6970 bios
even with ccc or ab v2.1. BETA 7

[Mydog]

When you have Asus bios use SmartDoctor to enable "Overclocking range enhancement"
Then close SmartDoctor and fire up AF or "AF voltage unlocker", that's what I've done.

SmartDoctor ver?
It has to be the correct one, I'll check mine when I Get home I' on iPhon now
