A STONED GUY Posted April 25, 2007 Share Posted April 25, 2007 I have 2 gig. of twin2x2048-6400C4, which works great. I decided i needed to buy 2 gig. more, so i would have 4 gig. in total, 4 modules. That should not be a problem with the Asus p5b Deluxe motherboard. I've tried all possible install combinations, and no matter what i do i get the system to detect 3 gig. (3008 mb exactly). So all modules are working alone. There is a small difference on my old modules and the new ones. The old is version 1.2 (xms6404v1.2), and the new version is 2.1 (xms6404v2.1). Operating system is Windows VISTA Premium. What can i do? Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted April 26, 2007 Corsair Employee Share Posted April 26, 2007 What does it detect in the Bios for installed memory, and what does it detect in http://www.memtest.org? And you might have to enable the memory hole option if its listed. Link to comment Share on other sites More sharing options...
A STONED GUY Posted April 27, 2007 Author Share Posted April 27, 2007 In bios it detects 3 Gig. In Memtest it detects 3 Gig. About the memory hole option, i don't see any option like that. Any idea what that would be called in an asus motherboard? Link to comment Share on other sites More sharing options...
A STONED GUY Posted April 27, 2007 Author Share Posted April 27, 2007 I have also tried the ram in another computer also with an asus p5b motherboard, which also had the same modules, so i have 2 motherboards and 6 of the same modules, and no matter what i do, i always get 3 gig. with 4 modules inserted in either motherboard.

sylvestre Posted April 27, 2007 Share Posted April 27, 2007 I have the exact same behaviour in same conditions. P5B Dlx, C2D 6600, and 2x TwinX2048 6400C4 => 3008 Md recognized. Any solution to this ? Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted April 30, 2007 Corsair Employee Share Posted April 30, 2007 Go to Advanced Chipset and enable Memory Remap in NorthBridge Re-map; BUT YOU CAN ONLY DO THIS WITH A 64 BIT O.S. Link to comment Share on other sites More sharing options...
A STONED GUY Posted May 1, 2007 Author Share Posted May 1, 2007 Go to Advanced Chipset and enable Memory Remap in NorthBridge Re-map; BUT YOU CAN ONLY DO THIS WITH A 64 BIT O.S. With Memory Remap, the bios detect 4 gig. but then windows Vista(32 bit) only detects 2 gig. I guess there is just no way to make this work with 32 bit windows.

Corsair Employee RAM GUY Posted May 1, 2007 Corsair Employee Share Posted May 1, 2007 The only way is to upgrade to the 64-Bit version, it should be in the package at least mine was. Link to comment Share on other sites More sharing options...
sylvestre Posted May 2, 2007 Share Posted May 2, 2007 Thanks, working great on Home Premium x64. The 64 bits version is only distributed in ultimate version, for others you have to request it to MS (and pay 10$ for shipping). Link to comment Share on other sites More sharing options...
