Well I got my new Phenom II 720 in the mail a few days ago, along with a Zalman cooler. This is the first time I have tried to over clock the CPU, so had a question. I overclocked it from the stock 2.8ghz up to 3.18ghz, and it loads fine. When trying to go any higher it wont POST however, I have heard of people getting this up to 3.6 on air fine and I was just shooting for about 3.4ghz. I have the GIGABYTE GA-MA78G-DS3HP MB, and some G.Skill x G.SKILL 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800. I did switch off the automatic overclocking feature on the MB(suppose to adjust voltages, etc for you as you overclock) and upped the volts from 1.8 on the RAM to 2.0. This allowed me to get up to about 3.23 without trouble. I cannot seem to get it higher than this though, I have a feeling it is my RAM as it's older RAM(about 2 years).
Anyways so I ran the IntelBurn test 5 times and it passed fine(never going above 32 Celsius), then I ran the Prime95 + Blend and the third core failed within 3 minutes. I then re-ran Prime95 in the Small FFT's, and let it run overnight. Woke up this morning and it is still going fine, reading the Prime 95 descriptions it seems Blend tests the RAM as well as the CPU. So is this anything to be worried about since it ran the second time 7+ hours? Should I underclock it a bit more? And do you think this sounds like I just need some good new RAM? Thanks for any input!
