Upgrading memory problem

Hello There,

I am trying to put in 2 x 1gb ddr memory sticks equalling 2gb instead of 1.5gb I have in now everytime im trying to put the stick its causing my windows xp stopping from loading.

i cant even load up in safe mode but once i put the 512mb memory back in, it comes up normally.


the memory sticks im using is 1gb ddr 400mhz

but the other 1gb stick is the same make which making up 1.5gb memory

can anyone help me

 

just an update it looks like my computer dosnt like running 2gb only at 1.5gb maximum memory.

 

Use Everest and tell us what mobo do you have.

 

ok here is the report.

On all sites it's say 2gb so something is wrong.

EDIT:Now I see what is wrong with tis picture:http://www.gigabyte.com.lv/products/mb/specs/ga-8siml.html

It says 2gb,but on 266 mhz.So bro......

 

i think there is something wrong aswell because I can run the new 1gb stick or the old 1gb stick but not just together otherwise windows wont load up.

I got the new 1gb stick in now and taken the old one out and it's working now so it's compatable.

 

So everything is OK?

 

well i think i know what the problem is, according to crucial website my motherboard can only handle 1024mb maximum so I am doing well to run 1.5GB.

thanks for all your help guys

 

"my motherboard can only handle 1024mb maximum "

Are you sure?My eyes see 2048.On Gigabyte site also.

 

yes im sure i done a scan and it said maximum memory capacity 1024mb. 2 slots with 512mb maximum. and in red it said please note do not exceed this limit.

at the top left hand corner the words said the following "according to our scan, it looks you have the maximum memory installed"

Just looked at Gigabytes site and your eyes are OK. 2GB DDR266 max.

 

to GoranP
The motherboard handles DDR266. Sexyand81 was installing 400MHz sticks. Would that be a conflict or compatibility problem?

 

The motherboard might support up to 2GB of PC210/2700, but only 1GB of PC3200. Strangers things have been done to chipsets. Do you have access to other memory speeds, just for testing purposes?

 

That's right Mimsy.Just as I writed above.2gigs on 266.So that's the limit of the mobo.And it's conflict.Like Mimsy said:2GB of PC210/2700, but only 1GB of PC3200.

 

yes i did put in 2 sticks of 1gb ddr 266 and the same thing happened again but when i take it out and leave 1 in and put in 512mb back in it works.

I just dont get it lol

 

If it were mine, by now I would probably just threw my hands up, installed the max that allowed me to use the machine, and surrendered.
But that's just me.

 

I have surrendered to the machine I have left 1 stick 1gb ddr 400mhz and a 512mb ddr 133mhz in and leaving it at 1.5gb memory

 

I hope you realize that your 400mhz stick will clock itself down to the slower speed.
But the lower speeds usually have better(lower)clock numbers so could make up some of the difference.

 

Its ok my computer is running reasonably fast as it is so i'm ok with that at the moment.

 

Educated guess: Bad memory controller on the motherboard. It's not really fixable, you'd need to replace the entire board. I would just settle for 1.5GB, mainly since the performance difference between 1.5GB and 2GB is very small.

 

hello again, I have done some more research in to the memory upgrading problem.

I found the motherboard on the manufacture's website and it states there it can only handle 1GB in total of memory. 2 sticks of 512mb.

The full make and model of motherboard is Columbia 4 GA-8SIML ver 1.2
