What courses prime95 to though "ERROR:ILLEGAL SUMOUT"???.... also the following issue maybe related... I am unsure... https://teksyndicate.com/forum/general-discussion/help-help-help-games-are-not-rendering-correctly/143655
it means your cpu is not stable, in it's processing, it is giving the wrong results for the calculations it's given.
