Well guys I just installed a watersink ( watercooled heatsink) and yes it running good. but my problem is well I would get this with out watercooling b 4 and i still seem to get it. what it is, is that when i try 504 on my 300a it posts' and some times starts to load windows. If I hit the voltage up to 2.2 would this solve it? BTW i am running a p2b. so aint got softmenu. The only way i can hit the voltage is if i cover pin b21 and all that garbage.. something i would rather not do. chip is 100% stable at 464 but is stubborn at 504. I could not even get 504 b 4 but now i guess the chips burned in and i can post and almost boot with it!
