Urgent help needed with laptop RAM problem
-
I have a laptop with two DDR SDRAM slots. The upper slot it has Twinmos PC2700 CL2.5 256MB, but system will report 225MB.
The other is the laptop provided Infineon 256MB 333 CL2.5 RAM.
Strangely my total RAM reported in My Computer is 480MB, instead of 512MB.
I have done dxdiag check it was 478MB total. What has happened to the other 30MB from Twinmos. Does anyone else experienced this? And what is the difference between ddr sdram and ddr sodimm?
Also when I switched the slots of RAM, such as RAM from slot 1 I put in slot 2 and that from slot 2 into slot 1, I cannot start my com and it reveal a blank screen. WTH? anyone knows what is the reason? I ascertain because I boot from hibernation.
I want to upgrade RAM on the coming IT fair but please help cause I am afraid of buying a RAM which I cannot use with my com. Can anyone know the average price of a 512MB or 1GB RAM? Also, will some memory be deducted from it?
The fair is coming up please reply asap. Thanks. Cheers. -
I have learnt a valuable lesson that you can't change your RAM by putting your com in hibernation mode as you will crash the boot up.

remember one thing. You may not get the full 512mb of ram
Some of it is gone for 'processes'
and your integrated graphics card uses shared memmory which means some of it is reserved for your graphics card. You cannot alter the amount reserced for your graphics card. Taking out ram while during hibernation is also dangerous due to electric shock and you might spoil your modem
Based on the info given, your laptop is using PC2700 a.k.a. DDR333 . Look for that type of ram and make sure it's for the laptop not for pc. -
The missing memory used for other functions maybe like for your graphics accelerator?
-
Do you use an integrated graphics card?
512 - 480 = 32MB of integrated graphics. -
DDR Sodimm is a type of RAM made for laptops.

hey mayi i ask u ar, talking abt integrated graphic, the total ram reported in My computer was 504MB, but my laptop is fixed with a 512MB RAM. i am using intel graphic media accelerator 900....so where did the 8MB go to? does it go to the integrated graphic or somewhere else?Originally posted by ndmmxiaomayi:Do you use an integrated graphics card?
512 - 480 = 32MB of integrated graphics. -
a laptop maximum can only put 2 rams ar?

Yep... Me using the integrated graphics accelerator card, running on 1024Mb DDR 400Mhz SoDimm RAM, but out of these 1024Mb, 8Mb used for graphics memory...Originally posted by hiphop2009:hey mayi i ask u ar, talking abt integrated graphic, the total ram reported in My computer was 504MB, but my laptop is fixed with a 512MB RAM. i am using intel graphic media accelerator 900....so where did the 8MB go to? does it go to the integrated graphic or somewhere else? -
Yup... check your laptop specs... 8MB should be allocated to the integrated graphics card.Originally posted by hiphop2009:hey mayi i ask u ar, talking abt integrated graphic, the total ram reported in My computer was 504MB, but my laptop is fixed with a 512MB RAM. i am using intel graphic media accelerator 900....so where did the 8MB go to? does it go to the integrated graphic or somewhere else? -

Depends on which integrated graphics you have...Originally posted by hiphop2009:huh....ooo....ic ics....only 8MB....so little...i wished dat could allocate like 100 MB to it
If you have a 900 or 915 chipset, your maximum graphics memory is 128 Mb...
If you have a 950 chipset, it can be at maximum 256 Mb... -
