I have gigabyte 6670 oc version with 1 gb ddr3,and i found out that it's limit in overclocking is waay too small.Highest i can reach without crashing is 860 mhz core,850 mhz memory.This card should easily reach 900mhz on core clock and on memory clock,what's wrong with it,i've used every software,any help will be appriciated...and btw it runs extremely cool,load temp is 45 degrees celsius,it has so much potential !!!
The 6670 chip itself has great potential. But individual overclocking results also depend on each particular chips. A great overclock in some is not necessarily reproducible in others. A 60Mhz/800Mhz stock is decent.
