did the pc give beep in any test condition?

nope, no beep whatsover, just the normal boot time beep. he's running gigabyte EP31-DS3L. that means that the timings can vary, even though the RAMs are theoratically at the same speed?

only one timing at a time but mobo can't decide which one to follow
then this RAM gaduh with that RAM la..
so you use manual setting, follow the setting of slower /weaker RAM

menu is same as this right? http://bak2.beareyes.com.cn/2/lib/200805/14/164/BIOS09.JPG
sorry, i can't find TRC too

DRAM RAS# Precharge (TRP) 4,5,6
and Precharge delay (TRAS) 14,15,16 --as this two settings should affect TRC value (minimum TRC=TRP+TRAS)
or worst case put RAS# to CAS# Delay (TRCD) to 6 with Auto the rest

anyway try at own risk. if it doesn't boot, clear CMOS will restore factory setting.

pardon me, but i'm kinda confused now, man the ram timing stuff is pretty complicated ohmy.gif

anyway, here's screenshots of the timing settings in the bios. maybe can point out which value to change?

i've manually set the standard timing controls, the settings must have went back to auto, coz when i inserted the other ram, it didn't pass the bios.

what values do i need to change in the advanced timing control section?

yes it can. the difference is the speed between the 2 rams. since both are DDR2, the connectors are the same smile.gif

make sure your 800 ddr2 is also sodimm ram, if desktop ram you cant fit into laptop ram slot, if both also sodimm can use together but ram speed will remain at 667Mhz

Wah i shock like hell when my pc fan suddenly turn on jet engine mode. The noise was so crazy. I never expect the fan to be so powerful until today.

So question is since only one memory stick is broken can I mix it up with a new 667 Mhz stick in the same slot? Would it still be able to run in DDR2? I am asking because 667Mhz stick is cheaper than the 533Mhz version.

Any help can appreciate. Thanks.
