Windows Forum / Windows Vista / General Topics / May 20084gb showing in Sys Info but only 2gb showing in Task Manager
Hi, I just installed an additional 2gb of RAM on my system, but this is not showing in the Task Manager. It iniitally was not showing in either, but after installing SP1 Sys info was updated. Please help. 680i SLI Mobo 2 X 8800GT 512mb Quad Core Q6600 Vista 32bit 4gb - OCZ Sli ready RAM - 1066mhz (DDR2) > Hi, > [quoted text clipped - 7 lines] > Vista 32bit > 4gb - OCZ Sli ready RAM - 1066mhz (DDR2) Is memory remapping enabled in the BIOS? If so, disable it. Memory remapping is only for 64 bit OSs, to move the hardware addressing to above the highest physical memory. I have found that enabling memory remapping for XP or Vista 32 drops the useable (Task Manager reported) memory to 2GB. >> Hi, >> [quoted text clipped - 13 lines] > memory remapping for XP or Vista 32 drops the useable (Task > Manager reported) memory to 2GB. But doesn't Vista 32bit only use a max of 3GB of RAM anyway? Netty >>> Hi, >>> [quoted text clipped - 17 lines] > > Netty Vista 32 bit and XP 32 bit have access to 4 GB of virtual address space. Of that, 500 MB to about 900 MB is reserved for hardware addressing. The biggest user is PCIe video cards, as the video RAM is mapped into the addressing space. What's left, usually 3.1 - 3.5 GB, is available to Windows. Each running application has its own 4 GB of virtual addressing space subject to the above limitation, and the virtual addresses are mapped into available physical RAM as required. This allows concurrently running applications to use the same memory space addresses, but different physical RAM addresses. Ian D I did this whole 'disabling of memory remapping' thing as I am doing the same thing as the author of this post was doing. I have found that it indeed raises the amount that XP32 registers, however, it caused a serious crash in my system when I attempted to run anything stressful to the RAM (Call of Duty 4 for example). I actually got the blue screen of death a couple of times. I re-enabled mapping, and the problem went away. My question is. Does this have anything to do with my having an SLi video cards sucking up 1gb of Video RAM? Even so, my mobo can handle up to 8gb of RAM. Could it be that my RAM sticks are conflicting with one another (2 are Patriot brand, and 2 are G.Skill)??? Not sure if what to do here. I've listed some of my system specs below. Asus P5N32SLI SE Deluxe 2.02 G Mobo Core 2 Duo 2.13ghz E6400 4M Cache 1066mhz EVGA Nvidia GeForce 7950 GX2 1gb 2gb DDR2 PC-6400 (Patriot) *RAM addition = 2gb DDR2 PC-6400 (G.Skill)* The RAM says the timings are the same, but I'm not sure about the older Patriot RAM, as many have said they have issues with it. Any help would be greatly appreciated. Thanks ahead of time. > >>> Hi, > >>> [quoted text clipped - 28 lines] > space addresses, but different physical RAM addresses. > |
