I have oher question.
Highest supportd by m mobo model is 6400+. 6400+ black edition is not listed, but they listed 5000+ and 5000+ black edition as seperat models. http://www.abit.com.tw/cpu-support-list/mb/nv_nforce4ultra_kn9.htm
This is confusing because it suggest that 6400+ black may be not supported, however there are no deifferences between 6400+ and 6400+ black in terms of technology apart from that it is unlocked and easy to tweak... Tell me if I am wrong?
