Ridlas Posted July 23, 2009 Share Posted July 23, 2009 I get the same problem, says 4GB and only using 3.12GB or something. Even though I have the x64 version.

Knightwolf20024 Posted July 23, 2009 Share Posted July 23, 2009 what are your computer specs , i think it reserves some ram if you have an intergraded graphics card.

+LogicalApex MVC Posted July 23, 2009 MVC Share Posted July 23, 2009 The only thing important is posting your chipset. I don't think Intel chipsets before the P35 or something like that (I could be a generation or two off in my memory) can't actually address over the 32bit limit so you won't get the full 4GB no matter what you do (short of buying a newer board). The other problem could be you have "memory remapping" turned off in the BIOS. That feature has to be on for you to address RAM amounts larger than the 32bit limit of 4GB.

infamous84 Posted July 23, 2009 Author Share Posted July 23, 2009 what are your computer specs , i think it reserves some ram if you have an intergraded graphics card. i have an dell xps m1710 laptop, my gpu is an nvidia 7950 gtx, i've never had this problem in xp or vista both showed full 4gb the chipset i have is the P45, i did a same install on a newer laptop with the same chipset and it showed the full 4gb i've checked the bios and there is no option for memory remapping, i dont know what else the problem can be i've tried multiple clean installs and still nothing Link to comment https://www.neowin.net/forum/topic/801014-ram-issues-in-64-bit/#findComment-591319334 Share on other sites More sharing options...

footgay Posted July 23, 2009 Share Posted July 23, 2009 DELL XPS m1710 uses Intel 945PM chipset. Intel 945PM's Memory Mapping capability is 4GB like x86. Which leaves you about 3GB for RAM. http://www.pcper.com/article.php?aid=280&type=expert http://www.intel.com/Products/Notebook/Chi...PM-overview.htm http://www.thinkwiki.org/wiki/Intel_945PM This is why you should not get illegal versions off the net.Microsoft has even stated that some of the versions arent the versions that they state they are. What do 'leak builds' matter in this Memory Mapping thing?

Subject Delta Posted July 23, 2009 Share Posted July 23, 2009 This is why you should not get illegal versions off the net.Microsoft has even stated that some of the versions arent the versions that they state they are. The RTM builds (X86 and X64 of 16385) leaked are actually the official builds, they have the correct build tag Link to comment https://www.neowin.net/forum/topic/801014-ram-issues-in-64-bit/#findComment-591319920 Share on other sites More sharing options...
majortom1981 Posted July 23, 2009 Share Posted July 23, 2009 They say they are the right build tag but Microsoft themselves stated that slot of them are other builds with the numbers hacked to say the right ones.

Plus do u trust that nothing else has been changed to do bad things to ur machine? Do you want Microsoft to approve this, "Yeah, those builds that have been leaked are real"? Even though they can hack build numbers, they can't hack "Digital Signature".

footgay Posted July 24, 2009 Share Posted July 24, 2009 What are those other laptops? I think those laptops have different chipsets, apart from 945PM. Also just Windows 7 RC tells you 4GB that doesn't always mean 4GB usable. You need to look at Task Manager's Performance tab, and see if it shows Physical Memory in Total = 409x. And I don't quite understand about 7600G. If I've not missed a thing here, there's no such processor.

Run CPU-Z and paste a screenshot of the "Mainboard" tab... http://www.cpuid.com/download/cpuz/cpuz_152.zip Reason I'm asking is because the P45 is a desktop chipset not a laptop chipset. The laptop chipset is a PM45 (Dedicated Graphics) or GM45 (Integrated Graphics) as shown in my CPU-Z screenshot below. You saying you have the P45 chipset makes me think you're guessing what chipset you have and you're not actually sure...

+LogicalApex MVC Posted July 24, 2009 MVC Share Posted July 24, 2009 ok, sorry you are right about the chipset it is the pm45 No, the chipset in that screenshot is NOT the PM45 it is the i945PM they are not the same (That chipset is two generations older than the PM45)... With that said, you can't use all the 4GB of RAM because your chipset can't address all 4GB of it. It isn't a Windows limitation it is a limitation of your chipset.

If your other laptops are showing the correct amount of ram, and it's only one that's mis-reporting, then it's not the OS that's at fault.

spaceelf Posted July 26, 2009 Share Posted July 26, 2009 HUH? on x64 users see 3.25GB??? what the? This is very very odd thing I've ever read! hope this is not true! It has to do with the BIOS I believe. BIOS code is the oldest part of any current computer. I can't wait til it's finally ditched. Even though that might as well be never happening, since the replacement is available and nobody is using it. (Aside from Apple, who I couldn't care less about.)
