F2-6400CL4D-4GBHK overclocking

[asylum]

hello,

i need memory 1000mhz+ 5-5-5-15(abit ip35 pro), and was going to buy F2-8000CL5D-4GBPQ.

then i've found in local store F2-6400CL4D-4GBHK g.skill kit, but no reviews on internet. i remember F2-6400CL4D-2GBHK were great overclockers, is that right relatively to F2-6400CL4D-4GBHK?

thanks

[G.SKILL]

it could be overclocked little, but not sure how
