If you're worry about your rams overheating then get some rams heatsinks and place an small 80mm fan blowing decent airflow to the rams. Then run some memtest on those rams to narrow down it's errors. So if it cuases errors during the (assuming that it is) then you know it's not becuase of overheating but the rams itself has defects.
thanks for the tips. I'm not positive if it is my RAM overheating, but I always get kernal packet errors and I have narrowed it down to either RAM overheating (but unlikely) and HD (i am almost positive this is it)
