6950/6970 memory or core oc?

[mranderson]

What method of oc will offer better results? I mean if you increase memory speed or core speed by 10% will you get the same improvement in FPS?

The scaling won't quite work like that, but you will see better initial results with a good core overclock.

My GTX 480 will overclock higher on stock voltage by justing adjusting the core. I prefer this as it keeps the temps down.

Hi, my Toxic@6970 > 935/1350 + 20% powertune via catalyst control centre.

The core will go higher the lower the memory is clocked with my 6950>70 crossfire setup, 1ghz/1300mhz, if I want to go even higher, I need to lower the memory to 1250mhz.

Using AC Accelero coolers in case your wondering.

Did some testing and the memory oc offers much less of an improvement compared to the core frequency.

I have found that even small core OC (by just 20 or so) when running my 6950's in single card mode can give about 5-10 fps in fur-mark. overclocking the ram just doesnt give that much of an increase (for me at least)

Here's the settings on my 6950 2GB (6970 Unlocked)

I gain around 5-10FPS on average in games with the OC. I have the Accelero cooler too which is amazing, keeps the card very cool and I never ever hear it.

Tried the same with my 6950 (1050 core and 1400 memory) and the improvement was again more obvious when oc core than memory.

Don't think mine will go much past 980 core from memory, can't remember now!
