Memory OC Holding Me Back - Any Idea's?

post #1 of 3
Thread Starter 
So, I stuck a MCW80 waterblock on my GTX 460 SE and I can get my core clock up to 1025, my shader up to 2050, but my memory cannot get past 1850.

I am pushing 1.075v through it and my load temp is 40C. I have heatsinks on all the memory chips, the mosfets, and any other chip found on the card.

I see people getting memory clocks over 2000 on these cards. Am I able to push more voltage through my memory chips to get them to overclock higher? What is the missing link here? I topped out in benchmarking on an 1850 memory clock back at 925 core.

I am kinda wishing I grabbed a full waterblock now, but I got this block for $32 and could not spend much more.

Make sure a good air flow at the card, maybe a decent fan can reduce the heat of the memory and vrm chips.

It is pretty good as far as the case goes, but nothing direct on the heatsinks. Here is a photo that let's you see it sort of.





On a side note, I re-ran 3D Mark 11 and went from 3500 to 3800. I guess the 1000MHz clock did squeeze more out and I also overclocked my NB to 2800 MHz.
