I didn´t understand the last part, what do you mean that memory doesn´t make up for core performance?
I should first try to get my core to the max that my stability+thermal statistics can do, then adjust memory according to what?
I found this quote:
"Core clock increases will always be more effective than memory clock increases, as it is the GPU that does the brunt of the processing. The memory overclock doesnt really increase its speed in mhz, but actually increases its data transfer rate. Increasing the memory clock will allow the memory to trasnfer data quicker, leading to faster loading times, rendering times ect. However, too high a memory clock and you will start to see artifacts on the screen, sometimes to catastrophic effects. I myself have overlocked the memory too far, (Burnt out a 550Ti when bumping up the memory by +1200mhz! Derp). You may well ahve found the optimal settings for your card, so note them down, but contiue to play around with the clocks. I tend now to increase core more than memory, as memory doesnt do too much to increase performance, but a higher memory clock will increase power consumtion. I have even undercloked my memory before now to keep a more stable power supply to the GPU.
With regards to your PSU, Dont worry. I have the same one, and the thing to remember is that the cooling fan on the bottom diesnt turn on until the PSU reaches a certain temperature. Part of the reason for its 80+GOLD rating is becuase it works more efficient when warm.
Hope this helps!"
I think this means I should mostly rely on core OC and not use as much memory OC, maybe +100 MHZ from stock max as I understand the power consumption is worse compared to Core clock.
