Overclocking priorities - Core Clock vs. Memory Clock (AMD)

[VG Docs]

I was thinking about overclocking my Radeon 6950 nearly to its limits (While remaining stable of course), but I'm most certainly no expert with overclocking.

Right now the overclock is at 6970 specs (880 core/1375 mem), how should I prioritize the overclock? Will a higher core clock prove more useful than a higher memory clock speed? If so, then would it be a good idea to lower my memory clock speed in order to achieve a higher core clock speed, or vice versa? 

 

Any tips for overclocking are welcome.

I usually start with finding the Max core clock then raising the memory clock on my 6850 afterwards

Would you be interested in unlocking it to a 6970 through a BIOS flash? That could yield you even more performance increases if you can cool it.

I already did that, that's why my specs are 880/1375.

But did you unlock all of the shader cores?

Your 6950 is already almost at it's limit, they do not OC well.

 

Let me know if you beat my old GTX 480:

Yes, I did.

Really? I heard they were really good overclockers. Oh well.
