Stop memory checksum errors on Kingston FURY DDR3 1866?
Every time I tried to enter a new area, my PC would just hard reboot without warning. Getting kicked out of a hunt at the climax is a special kind of torture. After some testing, I found the Kingston FURY DDR3 1866 voltage was dipping below 1.45V under load, triggering memory controller checksum errors. I tried downclocking to 1600MHz first, which reduced the crashes but cost me about 12 FPS—I was honestly starting to panic. I went back into the BIOS, manually pushed the DRAM voltage to 1.55V, and loosened the tRFC timing to 260 cycles. I ran four consecutive passes of MemTest86, and those 22 errors completely disappeared. The only catch was that the sticks hit 62℃ initially, but I fixed that by cranking up my case fans, bringing them down to 48-52℃. CPU temps stayed around 68-74℃. After six hours of hunting, the crashes are gone, but it's a bit of a struggle to keep the temps low.
