Any ideas?
if you leave the core at stock speeds, can you overclock the ram without issues?

my vid card would not overclock the core at all.. I was stuck at 275.. but my ram would go to 290 just fine.. I ended up doing a hardware volt mod (no pencil) to my card also changing out the stock fan for a custom fan and ramsinks.. I now can get 297/300 stable with no artifacts.. However some people can go higher with a stock set up.. I just got a bummer card..

I use Powerstrip to do my overclocking..
