Randomvity Posted September 6, 2006 Posted September 6, 2006 Like it says, I have 4gb of RAM in my board, but my BIOS and Windows are saying that I only have 3gb. I have no idea. I upgraded to the x64 edition of Windows XP, but it didn't solve the problem. D: Any ideas? I'm pretty newbie at all of this.

Mussels Posted September 7, 2006 Posted September 7, 2006 can you try running just 2 seperate pairs and see if its one stick thats playing up, or one ram slot thats not detecting the ram? Quote Share this post Link to post Share on other sites More sharing options...
Simon D Posted September 7, 2006 Posted September 7, 2006 You will need to enable S/W & disable H/W Memory Hole Remapping within the Bios to see full 4GB on bootup Simon Quote Share this post Link to post Share on other sites More sharing options...

Guest BFG Posted September 8, 2006 Posted September 8, 2006 In windows you will still only see 3.51 gigs of ram. Quote Share this post Link to post Share on other sites More sharing options...
Simon D Posted September 8, 2006 Posted September 8, 2006 You may need to check the value of bottom of 32bit [31:24] IO within your bios. My read C0 (zero) for 4Gb Simon Quote Share this post Link to post Share on other sites More sharing options...
Randomvity Posted September 11, 2006 Posted September 11, 2006 Thank you for the replies. I haven't been home, so when I get there I'll try out all your suggestions. Quote Share this post Link to post Share on other sites More sharing options...
MarkAuer Posted September 24, 2006 Posted September 24, 2006 I'm having the same problem. To get the BIOS to see all 4GB you need to enable S/W Memory Hole Remapping in Advanced Chipset menu of the BIOS and disable H/W Memory Hole Remapping (with H/W MHR enabled, the mem test was only getting as far as 3.5GB) I still can't get 32bit XP Pro to see more than 3GB though. It's not the /PAE switch as it seems to have loaded Ntkrnlpa.exe on it's own accord judging by the General tab in the System Properties window. (I think this was enforced with XP SP2 and has to do with DEP) Simon D: Are you seeing the full 4GB physical memory in the Task Manager? Are you using XP Pro (SP2)?

Praz Posted September 24, 2006 Posted September 24, 2006 It's not possible to have the use of 4GB with SP2. The most you will see is 3GB-3.3GB. Quote Share this post Link to post Share on other sites More sharing options...
Gipse Posted September 24, 2006 Posted September 24, 2006 XP PRO 32-Bit can only handle 3GB, so you will never (until MS releases a patch) full 4GB of Ram... Gipse Quote Share this post Link to post Share on other sites More sharing options...
