can't boot with 2 sticks of ram.


Recommended Posts

i can't seem to get 2 sticks of ram to boot. i have a opty 170 as a cpu. i decided to remove the ihs. pirior to removing the ihs i have been able to run both stick in the mobo fine with oc. but now after removing the ihs. i can't seem to get the 2 sticks to run at the same time.

if i boot with 2 sticks of ram i seem to get 3 LED flashing. i can only run one ram on either the yellow or orange slot closest to the edge of the mobo. i can't run 1 stick of ram in either yellow or orange on the slots closest to the cpu. it's weird. i can't boot into bios with ram in yellow and orange near the edge of the board.

 

i wonder why this is a problem ? does anyone know how to soolve the problem? thanks

btw there are no physical damages on the pcb's on the cpu nor is there a crack core. i can run the comp fine but only on one stick of ram. i tried a 6+ hr cmos reset but didn't seem to cure the problem.

system basically won't get into any part of the bios with 2 sticks of ram and the mobo will show the 3 LED

Does either stick work properly or just one of them?

 

I would use memtest on each stick to see if they are both working properly.

both cna run properly. i don't know about memtest i have not memtest each of them. i can use either one and ti will boot to windows. but i can'ts use bother of them at the same time

Three led's mean that the CPU has been identified, but the RAM cannot be found. Just had that problem myself.

 

I booted with one stick in DDR 2 (Orange slot farthest from CPU.) and then powered down. Ran the other stick in the same slot and powered down. Then, I installed both sticks in DDR 2 and DDR 4 and cleared the CMOS and it has been fine since.

 

Who knows why?

i will be trying this. if it doesn't work then i'll memtest. let's hope for the good news. i'm sick of runnin 1 stick of ram. sucks to have the cpu bottlenecked with 1 stick of ram at 512mb

i am able to boot up the comp with 2 stick of ram on the orange and yellow slots fartest away from the CPU. but not able to boot up with 2 sticks when i use both orange or both yellow. any ideas? currently runing fine on stock speed without oc.
