errors in games could be like a pixel getting drawn wrong or a slight glitch in the A.I. of cpu opponents
memtest and prime calculte numbers and already have the answers so they can check the calculations are correct so even one little bit that is wrong will show up
whereas in games these tiny errors are not so noticeable
thats why i dont bother with these type of benchmarks as im not looking for supercomputer accuracy it works the way i want it to so im happy
maybe when i move upto amd64 i will make sure its super stable but if prime etc dont cooperate with me straight away then im not gonna bother my ass with them
an dont give up keep messin around check the for sale section and ebay for used ram that is good quality , look out for things like winbond bh5 chips or samsung tccd
