Tweety.Abd Posted June 26, 2011 Share Posted June 26, 2011 Hello,I've got 4 G.B. RAM on my laptop, but it's only showing 3.87 G.B. usable of the 4 G.B. I'm using Windows 7 x64 and I should be able to get all 4 G.B. right? I have a graphics card, but it has it's on own dedicated memory of 1 G.B. (Mobility HD 4650) I'm not sure why I'm being denied the total 4 G.B. I'd be really glad if anyone could help me about it. Regards,-Tag Link to comment Share on other sites More sharing options...
Sonar Posted June 26, 2011 Share Posted June 26, 2011 There is an option in the bios to allow the full use of 4gig 8 gig or even higher...EDIThttp://support.microsoft.com/kb/929605 Link to comment Share on other sites More sharing options...
RobrPatty Posted June 26, 2011 Share Posted June 26, 2011 Go into MSCONFIG/BOOT/ADVANCED OPTIONS/ and see what Max Memory is set on. Link to comment Share on other sites More sharing options...
pr1xsel Posted June 26, 2011 Share Posted June 26, 2011 Probably your GPU is allowed to use that ram to save power and have more memory, some write that updating bios might allow to set the allocated size.Microsoft describes it this way: "Hardware Reserved Memory that is reserved for use by the BIOS and some drivers for other peripherals".

rseiler Posted June 27, 2011 Share Posted June 27, 2011 There is an option in the bios to allow the full use of 4gig 8 gig or even higher...EDIThttp://support.microsoft.com/kb/929605Unfortunately, not in all cases. I know of a particular Gigabyte board when coupled with a Core i3 that absolutely will not give you the full 4GB no matter what you do, so there must be other cases too.

I don't think my laptop supports the memory re-mapping feature, so it doesn't work for me, but thanks for your help either ways :) Link to comment Share on other sites More sharing options...
Tweety.Abd Posted June 27, 2011 Author Share Posted June 27, 2011 Go into MSCONFIG/BOOT/ADVANCED OPTIONS/ and see what Max Memory is set on.It disabled, however if I enable it says "4096 M.B." but I haven't applied it yet. Link to comment Share on other sites More sharing options...
Tunerz Posted June 27, 2011 Share Posted June 27, 2011 Is your CPU Intel, possibly it allocated some memory for its integrated graphics? Link to comment Share on other sites More sharing options...
Tweety.Abd Posted June 27, 2011 Author Share Posted June 27, 2011 <br />Is your CPU Intel, possibly it allocated some memory for its integrated graphics?<br /><br /><br /><br />Yes, my processor is from Intel Crop. but I have AMD Mobility Graphics Card, as I've mentioned before.

pr1xsel Posted June 27, 2011 Share Posted June 27, 2011 We don't know what you have inside the laptop but newer Intel CPU have tiny GPU integrated inside the processor, good to have when your dedicated get's broken. You need to try updating your bios if there's any newer one that would allow to change your GPU default settings. When you turn on your laptop you need to keep pressing F2 fast at the very beginning to see options. Some laptops don't have much options and best is to contact the manufacturer to make new bios if it's possible. Manufacturers should know what hardware is allowed to reserve ram.

I'll try updating my BIOS, it doesn't offer much options though. Thanks for your response. Link to comment Share on other sites More sharing options...
toyo Posted June 27, 2011 Share Posted June 27, 2011 Google for "windows 7 x64 3.87 ram". It seems to be a issue for specific chipsets. A BIOS update might help. Link to comment Share on other sites More sharing options...
RobrPatty Posted June 27, 2011 Share Posted June 27, 2011 This is off subject but while you are in msconfig allow all your processors to work. Just check number of processor and use the drop down button to click on how many processors you have. Also go ahead and use the memory amount shown as you maximum memory. Then go to your properties page and see what your usable memory is. Link to comment Share on other sites More sharing options...
