Scrypt Mining - Core or Memory Clock?

[benmuc]

Hi,
i am currently GPU mining LTC as well as some others using CGMiner. I have read that those currencies based on Scrypt are rather intense on the GPUs Memory.

Should my focus be on overclocking the GPU Memory rather that GPU Core? I could of course do both, but then i would have to overvolt which would get me into troubles concerning the temperatures. So i basicially just want to use the available overhead in Vols to overclock one of the two.

What do you say? Core or Memory?

Thanks!
