Well , I'm able to run my barton 2800 @ 3200 speeds with quite easy and only using 1.72vcore. Case temps are 30C and CPU temps are usually 32-33C. I'm running an Abit NF7-S v2.0 with PC3500 mushkin lvl2. I've been able to run my comp 10.5x214 1.75vcore prime stable and everything and still only get a max load of 39C. Thing is , when I up it to 11x214 and up the vcore prime will usually run for about 13hrs or so then it just crashes. I'll click on prime when I wake up and it just vanishes from my task bar. I'm taking this as instabality but I'm not quite sure , any ideas or methods I should try.
