Hi

My mobo Gigabyte GA-7N400 has four(4) DDR1 RAM slot.

Current RAM:

Slot 1 - 512Mb Kingston
Slot 2 - Empty
Slot 3 - 512MB Kingston
Slot 4 - Empty

Was ok...system detect both as 1024Mb.

Then bought additional Kingston 2x512MB DDR1 RAM.

Now:

Slot 1 - 512Mb Kingston (old)
Slot 2 - 512Mb Kingston (new)
Slot 3 - 512MB Kingston (old)
Slot 4 - 512Mb Kingston (new)


Problem is, it detect all four(4) RAM as 1024Mb
If two(2) RAM...512MB.

I found out that it's the Slot 1.
Proof is when I install only three(3):

Slot 1 - Empty
Slot 2 - 512Mb Kingston (new)
Slot 3 - 512MB Kingston (old)
Slot 4 - 512Mb Kingston (new)

It detect 1536Mb.
I've test all RAMs on other slots...all RAMs were ok so far.


Wierd though.
What's wrong with Slot 1?
Was ok before

no i mean... shouldn't it b 1GB?
btw i dunno ur prob lei... maybe mobo spoil ady?

try change new ram into slot 1. all ram same frequency or not?

try disable dual channel

In BIOS?

check ur motherboard manual to see how to properly arrange the ram(they got rules for it). also check the limit of ram ur MB can support.

I will.
I'm emailing the mobo manufacturer.

Forgot to add...all three(3) RAMs were double sided...only one(1) were single sided.
It does not matter though...because it's the Slot that was a problem.

Slot 4 actually not slot 1.

yes. the same answer here. as for another suggestion. Rub those 2 old ram with rubber eraser on the part that connet to female slot on mobo

I think it's not the RAM.
All three(3) of my RAM were double sided (DS)
Only one(1) is single sided (SS)

I've read the manual of my mobo.
The way was:

Slot 1 - DS/SS
Slot 2 - DS/SS
Slot 3 - SS
Slot 4 - SS


Crap.

Now I need to find a SS RAM.
Trade it with one of my DS RAM.

glad to be able to help

Thanks for any help

Oppps...I use all three(3) DS RAMs on Slot 1, Slot 2 and Slot 3.
Slot 3 supposed to be SS only from my mobo manual.

It detect 1536mb nicely.



Again, Slot 4 is a problem I think.

that's sad. anyway still got 3 port to be used.. have fun

consider selling it at garage sales section.

value ram???

i read that if u use windows Xp , it cannot detect 4 ram slots.. max 3.. vista can detect 4 slots.. so lol

anyway tumpang thread ya.. recently sometimes my computer when i startup, i get thet 3 endless loop beeps saying ram not detected.. then i take out my ram, use eraser to rub and blow the dust in the ram slots.. after that than can use.. but after 3-4 days the beeps come again and i have to remove the rams again.. any idea? motherboard or ram problem?

looks like slot prob la bro... rub it every 2 - 3 days...

Any source on that?

i am not too sure about that facts, but from waht i know. xp only detect 3.5mb. if higher than that, u have to use 64bit version OS both vista n XP
