6950 shader unlock with voltage control - Page 8

post #71 of 89
Unlocking the shaders and then manually overclocking is always the safest way to overclock your card, reason being, that the 6950 and 6970 use different memory and have different memory timings. Probably the reason you were getting the artifacts when you flashed originally...

Use GPU-Z to save original bios. Name the save bios original with ext. .bin and try again.

I'm not sure how long or huge the 570 is but the 6950 is bulky as well. Going from the 570 to a 6950 you won't notice any performance increase or decrease ( in certain games). But you do notice your wallet have more cash

the Asus DirectCU II 570 (as their 6970 and 2GB version of the 6950) are all 3 slot coolers... not that I will be SLI-ing in a micro ATX case

Hey I just bought a MSI 6950 Twin Frozr iii and I have been reading mix reviews on it being unlockable, it being able to have voltage tuning, etc.

I just got mine yesterday, and besides me having to send it back because the header where you plug in the displays is all bent to hell. I have not been able to tweek voltage to get a core past 900mhz and it is 850 stock. Using Afterburner that is modified to allow more OC'ing but still can't mess with the voltage.

I feel like I bought an expensive 6950 that just runs cooler than reference. Thoughts?

This has been mentioned before however I find it to be so awesome its worth stating again. I like to use Afterburner for OCing clocks and voltage and setup fan profiles. Unfortunately you can only OC the clocks to 950/1450 and to go beyond you have to enable unofficial overclocking. I get immediate BSODs whenever I try to enable it.

So to get the optimal HD 6950 OC setup I think a great solution is to:

1. Modify bios for shader unlock or flash to 6970
2. Install Afterburner and turn on voltage control
3. Establish fan profile
4. OC to 950 if possible
5. If stable OC at 950 then modify registry to allow higher overclocks in CCC. This also allows higher overclocks in Afterburner without enabling unofficial overclocks.

Follow the instructions in first post.

For me this is the best solution.

I've tried unlocking the shaders as per instructions provided here: http://www.overclock.net/12295527-post22.html

It appeared to run smoothly, but when I checked GPUZ I still have original number of shaders.

I need tips on what settings I should use in afterburner too. At the moment I have: Core Voltage 1110mV, Core Clock 900MHz, Memory Clock 1325MHz.

Could someone please help?

Can I elicit a little advice here? Mine is a MSI 6950 2gb reference model with shaders unlocked. Initially did the full 6970 unlock which was fine, but have rolled back to have more control.

1. Having used the registry hack to unlock the higher frequencies, and added PC +20% in CCC, do I just keep upping the GPU and memory clock till it fails and then start doing manual voltage to find a stable point (but not above say 1.3v)?

2. I have a hot room, usually about 28-30c ambient. I'm guessing that even with a bunch of case fans running, getting it above say 910mhz is going to be hard with sensible temps. Would having a case fan blowing into the card fan help (probably a spare Yate Loon 120mm)?

3. As I use a LCD tv as monitor with fixed 1366x768 resolution (for now at least), how can I really test for stability when I can't stress the card on hi-resolutions as you guys do? Or does this not really matter as the card won't ever get that stressed in gaming use (only FPS I play is Arma II titles currently).

Flash with atiflash under DOS. Try to mod with RBE. Reinstall the driver. If it still show 1408 shaders, your card is probably non-unlockable.

After flashing my 2 6950's to 6970's it's hard to get a stable overclock, I'm at 920mhz with 1.18v and games crash..
