Memory remapping problem - new RAM

[Makragic]

Hi guys,

I just bought DDR2 2gb RAM - now i have 2 sticks with 2gb each, first I had only 3.25 usable memory, then in BIOS I enabled "Memory hole remapping", and that causes system to crash, it's not about OS cause it crashes on W7 and on Linux Ubuntu... When it crashes you see few colors on screen and thats it, like rainbow. And you can't do anything, i changed Memory remapping back on disable...

I don't know what to do. I searched literally everywhere.
Here are my computer informations: http://www.dodaj.rs/f/2B/6O/4S8yzKdC/sys.jpg

Thanks!

Install windows 64 bit. 32 bit is your problem. The same key will work, just download the 64 bit and reinstall.

Ah sorry, i forgot to say, i have x64 both Linux and Win7...

Ok, but if i ignore "Memory hole remapping" how should I get full RAM? Currently I can only use 3.25Gb out of 4GB, and thats almost 1gb which i don't wanna lose. I mean, whats the point of buying 2gb of RAM if I can't use it?

The only solution for that problem I found is to turn on Memory remapping... I'm kinda confused now...

if you have 64bit windows 7, it should be using all 4GB, where exact did you see it only using 3.25 and what does it said exactly?

 

[Makragic]

It doesn't really matter is it Windows or Linux. When you start your computer there you can see how much memory there is, in my case there is 3200+ (I don't know exact number), also when you check "about your computer" in Linux there is 3.2 GiB, and if you see properties on My Computer in Windows there is: 4GiB (only 3.25 usable).

On the other hand, when I turn on Memory remapping, when you start computer it says: 4096, Linux: 4GiB, Windows: 4GB...

Look like it the chipset

ref 7

I'm sorry but I don't understand what are you trying to say 🙁
Can you explain it little bit? Please?

 

[rgd1101]

it mean the motherboard chipset only support 3.25 GB ram.

 

[Makragic]

But why? I as far as I know direct memory access has nothing to do with RAM memory limit...

http://www.asrock.com/mb/amd/alivexfire-esata2/
"Supports Dual Channel DDR2 1066/800/667/533 (4 x DIMM slots) non-ECC, un-buffered memory, Max. capacity up to 16GB"

Why would they say this?

Sorry for all those questions, and thanks for your help tho.

then they said, which pretty much mean can't access more the 32bit memory size.
**Due to the chipset limitation, if you adopt 4GB or more memory, the actual memory size
may be less than the installed memory size.
