Ive just upgraded to 4 gb of geil ULL and iam getting errors in memtest on test 7, i used to get these errors before with 2gb and i think i worked round it by upping the MCH and FSB voltages by +0.1 and DDR voltage to 2.3v but ive tryed it this time with +0.2v MCH and +0.1v FSB with the CPU running at 1.4v and the DDR at 2.2v and 2.3v but iam still get errors on test 7
memory is running at 5,5,5,15 2T with a 42 refresh cycle.
Any ideas?
