yeah still reboot, i just took out both and put in a single 512 chip and 256 chip same thing. Bios reads temp at 60c in BIOS. 57-60 maybe 61. Sometimes the pc freezes in BIOS =/. yes i got latest bios version. its like 60-65c is the limit my cpu can handle. i got a HP mobo, cant see model my GPU heatsink is blocking it lol.
i can even put a high powered house fan blowing into my case and it still overheats
