So, if you believe Raja tests on the X38 motherboards, you're already on the red side at 49°C, you should watercool or active cool that NB
You know, RAM errors can trick many type of errors. Especially, explorer memory access errors, windows desktop hanging, applications fatal errors and sudden reboots. If your NB is too stressed, the errors are RAM type.
Are you on VISTA64? GAR noted OCCT is unstable on his Vista64 even at stock, so could be a bug in VISTA64-OCCT. Or try it on stock settings for your CPU-RAM-MB. If it rocks, than maybe you could try more cooling on the NB like Raja stated
