Hey. I have random 0xc0000005 errors when playing. Dumps says they are for random files. I memtested all 4x2 for 8 passes and every single memory for 3 passes. I got no error. Should I RMA?

How can you check mems are faulty if memtest says they're fine? Do you have any better tools?

Would I be charged for unreasonable RMA if you won't find any defects?
