Its not the N/B but its the S/B. But i do have some problem too regarding N/B. Ive already done with the N/B mods, ive already removed factory's passive N/B and replaced it with vantec iceberg, but my problem is that ive used the the factory's pin with spring to attached the iceberg, but before i pinned it, ive applied AS3 on the N/B, didnt make any lapped method coz the N/B that comes with my MOBO is the all palstic ceramic type no aluminum chips inserted the one that ive saw on the forum, but it seems the iceberg was not fitted tight. So im wondering now to put Arctic silver adhesive, but im not so sure if it can still removed once it applied. Right now only that kind of solution is available here in our market and AS3. Im trying to look for arctic alumina glue but its not available here. So my question is if i will used this kind of adhesive, can i still removed it later if id like to? Is it something to do my overclocking? coz right now i can only overclocked my 2500 up to 11x195. It id pushed it higher, it can still boot but the problem is the windows anymore, ive always got a mesg of NTOS problem then hanged up.
