Shaun N. Posted June 12, 2009 Share Posted June 12, 2009 Hi guys, I have Windows 7 64 bit version installed but I can't find anywhere in my bios a place to enable memory remapping, Windows will still only use 3.25 Gigs of RAM. Either I can't find it/ or its not there. I'm wondering if it can still only use 3.25 of the available RAM are the programs still limited to the amount of memory they are able to use like in 32 bit OS? If they are then obviously i may aswell reinstall 32 bit Link to comment Share on other sites More sharing options...
Darrian Posted June 12, 2009 Share Posted June 12, 2009 Windows 7 x64 should automatically use all of your available RAM. You shouldn't have to do anything in your BIOS. If you're using integrated video it's will deduct the amount that is reserved for your video card. Link to comment Share on other sites More sharing options...
Brodel Posted June 12, 2009 Share Posted June 12, 2009 Yea, it should happen automatically. It did in my case anyway. Link to comment Share on other sites More sharing options...
Shaun N. Posted June 12, 2009 Author Share Posted June 12, 2009 I see a familiar word there, "Should" it isn't it shows "Useable 3.25 out of 4" Link to comment Share on other sites More sharing options...
Bryan R. Posted June 12, 2009 Share Posted June 12, 2009 Your signature doesn't list your motherboard. That bit of info would help. Link to comment Share on other sites More sharing options...
Brodel Posted June 12, 2009 Share Posted June 12, 2009 I see a familiar word there, "Should" it isn't it shows "Useable 3.25 out of 4" What motherboard do you have? I know you said you can't find a place to enable memory remapping, what were you looking for in the bios? It should be listed as PAE (Physical Address Extension).

Shaun N. Posted June 12, 2009 Author Share Posted June 12, 2009 http://www.foxconnchannel.com/Product/Moth...ID=en-us0000417 Foxconn G31MXP-K what were you looking for in the bios? Where I've googled I've found people being told to make sure Memory remapping is enabled but I've been through it a few times and can't for the life of me find it.

Shaun N. Posted June 12, 2009 Author Share Posted June 12, 2009 I'll have to see later (at work atm) I'll let you know in a few hours. I think I tried disabling the PEG setting from auto and it didn't work...or it wouldnt boot. cant remember :p Link to comment Share on other sites More sharing options...
Trivious Posted June 12, 2009 Share Posted June 12, 2009 I see a familiar word there, "Should" it isn't it shows "Useable 3.25 out of 4" Useable RAM is not the same as total RAM. Useable RAM means that some is reserved for OS functionality and its very likely in Windows 7 that it "locks" some of it down for special data transfer and storage needs.

veritas310 Posted June 12, 2009 Share Posted June 12, 2009 (edited) Utilizing all 6GB of mine on my Windows 7 64-bit drive. Not sure why you're still getting the 3.25...Your video card has 512MB RAM, that could be why it's appearing smaller as well. I think this is actually the issue, the shared video RAM is why your RAM size shows 3.25 available. On a 512MB video card, it will share and leave you with exactly 3.25 available. Your 4GB is there and recognized. You can choose in your BIOS whether to share RAM with your video card, as mentioned by a previous poster.

Shaun N. Posted June 12, 2009 Author Share Posted June 12, 2009 Ok, my settings are below I did however see this Display adapter type Radeon X1950 Series (Microsoft Corporation - WDDM) Total available graphics memory 1918 MB Dedicated graphics memory 512 MB Dedicated system memory 0 MB Shared system memory 1406 MB Link to comment Share on other sites More sharing options...
jbo Posted June 12, 2009 Share Posted June 12, 2009 It seems everything is in order. There is an update for your BIOS (dated 06/02/09), but there isn't a lot of documentation available. You could always try that if you haven't already... By the way, I have the same video card running on build 7100 x64, mine shows as: Total available graphics memory 2014 MB Dedicated graphics memory 256 MB Dedicated system memory 0 MB Shared system memory 1758 MB Link to comment Share on other sites More sharing options...
Shaun N. Posted June 12, 2009 Author Share Posted June 12, 2009 (edited) Does yours show useable 3.25? I'm on the same build as you Can I see a shot of your bios please? I havn't tried the Flash yet as I don't have a floppy drive at home. Edited June 12, 2009 by Shaun_ Link to comment Share on other sites More sharing options...

I havn't tried the Flash yet as I don't have a floppy drive at home. No, it shows as 4.00 GB. I'm actually using a completely different board (with the older Intel 965 chipset), I was trying to reassure you that your video card settings didn't seem out of norm :) Link to comment Share on other sites More sharing options...
Shaun N. Posted June 13, 2009 Author Share Posted June 13, 2009 Ahh ok, well thanks. I guess im gonna reinstall 32 bit then Link to comment Share on other sites More sharing options...
strelok1911 Posted June 13, 2009 Share Posted June 13, 2009 no it's because of the chipset (southbridge i think?) everything is 64bit but the southbridge isn't. I have THE same problem with my gigabyte ga-945g-s3. It doesn't uses the full 4 gb ram. Link to comment Share on other sites More sharing options...
Lamp Post Posted June 18, 2009 Share Posted June 18, 2009 no it's because of the chipset(southbridge i think?) everything is 64bit but the southbridge isn't. I have THE same problem with my gigabyte ga-945g-s3. It doesn't uses the full 4 gb ram. The southbridge is in no way related to the memory mapping. That is done at the northbridge. The similarity between your and the OP's mobo is that they both run northbridge chipsets (945G and G31) with a memory capacity of 4GB. This means that these 4GB also has to be used for mapping hardware memory. Hence the 3.25GB available for applications. In theory the motherboard does support 64-bit memory mapping, it just doesn't support high enough memory values to take use of it. Link to comment Share on other sites More sharing options...

I have THE same problem with my gigabyte ga-945g-s3. It doesn't uses the full 4 gb ram. Northbridge. His isn't really 64-bit capable so he's got that 3.25GB. Which honestly I think is BS, I could complain to Foxconn or Gigabyte. Link to comment Share on other sites More sharing options...

As long as it is able to address memory within a 64-bit memory area, but has a memory capacity of 4GB, it's still 64-bit capable. The G31 IS 64-bit capable. But I guess the box didn't explain that you need a higher memory capacity than 4GB to get any use of it. :p My point being, he doesn't really have anything to complain about. :D Link to comment Share on other sites More sharing options...
jjrambo Posted June 19, 2009 Share Posted June 19, 2009 If Vista x64 detects it correctly and Windows 7 x64 does not i say Windows 7 is broken. I have same problem with Laptop. Vista X64 detects and uses all memory, Windows 7 x64 does not. Windows 7 x64 should automatically use all of your available RAM. You shouldn't have to do anything in your BIOS. If you're using integrated video it's will deduct the amount that is reserved for your video card. It should but it does not and MS will probably not fix it just like they can't fix CPU speed for i7 processors. Link to comment Share on other sites More sharing options...
