did the pc give beep in any test condition?
no beep just minor memory timing mismatch, so find out the value for both KVR and CVS with cpuz tool
btw, what mobo is he running?

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

how do i adjust the rams tRC timings? the corsair one is running at 5-5-5-15-19. kingston is 5-5-5-15-20. i don't see any tRC timings in the bios. only tRAS. maybe i've missed it somehow?

hit CTRL+F1 once u entered BIOS setup, it will unlock become secret military base.
gaygaybite hahaha

yeah i did that already, changed the spd settings to manual, and then how do i proceed? i only see timings 5-5-5-15. i cant see the tRC timings

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

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?

guyz, i have a question here, abut sodimm notebook rams ...
lets say i currently have a motherboard using 667 ddr2 ram ... then on my hand got a 800 ddr2 ram .. can i fit the 800 ddr2 ram into my machine? ..
is the connectors behind the same? ...
sry ah .. noob in rams ...

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

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

thanks alot ..
so as long as the connectors are the same means can use right? ... and yes both are small pieces sodimm rams .. haha

tqtq

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.

yeah, my old lappy also using one 533 and one 667, should be no problem, but speed still remain 533

impressive explanation!! thanks!

anyone know how to check whether the ram have problem or not? becos my crucial ballistix seems to give me BSOD, when i remove 1 of the stick, its running fine.

Can notebook ram mixed with different brands but same spec?

Run it with Memtest86. It should be able to show whether there is a problem with the ram or not. Although my Crucial Ballistix did give BSOD problem last time but passed the Memtest. Still sent it for warranty and obtained a replacement which works fine (before crapping out again).

Yeah, no problem...
I did that with my laptop,
1gb transcend ddr2 800Mhz + (da original)512mb hynix ddr2 667MHz...
No problems encountered.

is my frequncy is right? sorry i'm so new in this..i buy ddr3 1333/pc10600isn't that i should get the frequency around 1333mhz? coz i only getting 686mhz only..
