RAM getting warm in slot but not detecting

[spartan86]

hello community,

this is my 1st post here.

i have an old asus p5nd motherboard and 4 sticks of 2gb ram. the issue is if i put ram in any of the 1st 2 slots (a1, a2), pc wont boot, but ram sticks get warm in those slots. b1,b2 slots work fine.

what could be the problem?

"if i put ram in any of the 1st 2 slots (a1, a2)"...wat does this mean???
how r u placing the sticks???...are a1 and a2, two blue slots or one black and one blue???
ur mobo manual shd have the right order...refer to that...

Define not boot do they warm up while the pc is sitting turned off
Or are you leaving it on & they are warming up

It sounds like you just need to install it properly

4 slots are colored in this manner : yellow black yellow black

in 1st 2 slots ram in not working
in last 2 slots ram is working

if i put ram in only any of last 2 slots pc boots, if i put ram in any of the 1st 2 slots pc wont boot but ram sticks warm up a bit.
so i think ram slots are getting power but ram is not being detected.

edit: they get warm if i leave the pc on. but pc doesnt boot when this is happening.

you just built the pc? Were the Ram ever worked?Did you change anything before this happened?

 

[spartan86]

i used this mb long time ago .. i dont remember whether they were working before or not .. i do have 3 1gb sticks lying around before i bought 4 2gb sticks so i think the slots were working fine.

what kind of issues can cause only 2 out of 4 ram slots to not work?

Some details for the RAM sticks? Manufacturer and model.

 

[spartan86]

elpida 2gb 2rx8 pc2-6400u-666

 

[slyverine]

did you check the RAM if they are compantible with your motherboard before you buy them? Did those 1gb RAM work on all slots?

 

[Zkye]

Try to install two modules in different color ram slots and then in the same color ram slots.

 

[spartan86]

i didnt check ram compatiblity but they are working fine in last 2 slots

these are the combinations i tried .. caps denote presence of ram.

Ybyb - no boot
YByb - no boot
YBYb - no boot
YBYB - no boot
yBYB - no boot
ybYB - booting
ybyB - booting
ybYb - booting
YbYb - no boot
yByB - no boot

and many others that didnt work but im confused already

only in 3 combinations pc boots

 

[Zkye]

yByb? If this doesn't boot either, there might be something wrong with the first two slots. A PC should boot with one stick in any of the slots.

 

[Zkye]

Also, try all 4 sticks in one slot that you know it works. Just to rule out faulty ram sticks.

 

[slyverine]

give us some info on your motherboard and previous RAM that were working! Those 3 RAM slots were working on slots 1,2,3?

 

[spartan86]

im not sure about which 3 slots but here are the details of previous ram dynet ddr2 667 64Mx16

asus p5nd
e5440
750ti
age old samsung 40gb ide drive

ill be happy to provide any other details

and rams are 100% working .. i have another pc i tried them on

Check this site , it's the asus support, check for supported memory. https://www.asus.com/Motherboards/P5ND/HelpDesk_QVL/
If it's not listed it's most propably compatibility issues with your motherboard, you should check for compatible memories before you buy them, not all RAM work on every motherboard!

They are testing only the most common brands. And his ram sticks work in some combinations.

are these 1gb sticks still working on the first 2 slots???

 

[spartan86]

1gb sticks also are not working in 1st 2 slots

 

[Hellfire13]

thn in all probability, the slots are broke...u might have to wrk with 2 sticks...

 

[spartan86]

right .. but ram slots are receiving power because ram sticks in those slots are warm up.
which components on motherboard can effect ram slots?

 

[slyverine]

getting warmed up may be also from overall system temperature, maybe they don't receive power.Or maybe they receive power and don't transfer data through the north bridge. You will have to remain with 2 slots.

i second that...
it cud be any number of reason, its getting warm...

 

[spartan86]

can it not be repaired? this board has seem to have northbridge heating issues .. even if i keep it on for 1 min , both northbridge and southbridge heat up to abnormal temperatures that cannot be touched by hand. will replacing heatsink on both make any difference?

 

[Hellfire13]

tht is the first thing i wud do in ur case...but significantly...updating to a fresh mobo wont be tht pricy as repairing a old one, even if its a old model to which u r upgrading...
