Memory question
I have put a new memory stick into my XP x64. I removed two 512 MB
sticks. This new one is 1024 MB. Why would my system still be saying I have 896 MB of ram? Do I need to do something in BIOS? When I had a 1024 and a 512 MB in there it was showing I had 1.3 GB of ram. How much Ram can XP X64 handle. Only as much as winserver 2003? Bill |

Onboard video has to get some RAM from somewhere so it steals it from system RAM. Looks like you are using onboard video and it is stealing 128MB for its special use. You might be able to alter the amount the onboard video steals from system RAM using a BIOS/UEFI setting. The more RAM you allocate to the onboard video then the better the video chipset will perform. Of course, that means less system RAM for use by the OS and applications. Here's some example articles (of MANY you can find in an online search): http://www.pvladov.com/2013/10/incre...eo-memory.html https://en.wikipedia.org/wiki/Shared_graphics_memory Don't know what mobo you have since you didn't give any hardware details. |

If you built it yourself, you should know if you accepted the onboard video or put in a video card to get better performance. You can use Piriform Speccy to give you some info on various components in your computer. There are lots of similar hardware query tools. Even the age-old msinfo.exe will give some hardware info. |

When I had a 1024 and a 512 MB in there it was showing I had 1.3 GB of ram. Some PCs like to reserve RAM for whatever. On-board graphics is one but for example my old Thinkpad T510i reserves 141 MB of RAM even though it has Nvidia graphics. I could believe it's because Lenovo uses the same Bios for variants of the laptop that use on-board graphics. Similar thing with a Dell Latitude E5440, Windows 7 Resource Monitor shows 95 MB as "reserved" and this one has on-board graphics only. Maybe you can do something in the BIOS, maybe not. I've gone through the bioses on these two laptops but in the end the best thing was to put more RAM in, 8 GB works pretty well for me. How much Ram can XP X64 handle. Only as much as winserver 2003? Microsoft says 128 GB for XP X64. For 2003 server 2 GB to 1 TB depending on variant. So more likely your hardware is going to be the limiting factor for RAM how much you can fit in and what hardware can address and not what XP X64 can handle. See https://msdn.microsoft.com/en-us/lib...(v=vs.85).aspx for RAM limits on different Windows variants. |

E7093v1.6.pdf ATI RS480/RX480 Chipset ATI SB400 Chipset There is no sign of the x32 RAM chip that was added externally to the Northbridge on some later ATI/AMD designs. So all the memory used by the graphics, comes from system memory. The manual has a few things in it, that seem irrelevant to the design. In Advanced Chipset Features, you will find UMA Frame Buffer [64M, 128M] AGP Aperture Size [64M] PCI Express graphics should not have an AGP GART, in which case such a setting would be ignored. The purpose of AGP GART setting, is to define a linear region of the address space, for translations. It allows physical memory gathered from various places, to have a linear address defined for it. So the AGP GART is *not* a direct usage of memory. It's address space. Now, on a 32 bit OS, with a memory license, defining a large GART chews into the available address space, so such a setting could have an impact on a 32bit OS with 4GB of RAM present. You would get less than "3.2GB free" if the GART was actually being used. And my experience was, that large GART settings seemed to destabilize the computer. The UMA is the one you should pay attention to. It only has two options. That's where your RAM went. The manual also mentions "UMA+sideport", but I don't see the sideport x32 RAM chip in the motherboard diagram. The sideport chip was really a "hood ornament", because it isn't fast enough to "accelerate" the performance of the video. The reference to "sideport" appears in only one sentence in the manual. I cannot see a sideport chip in this picture either. http://support.hp.com/ca-en/document/c00361515 Paul |

Memory question
That's it Paul! That's my motherboard. So there's no video settings to
change ? The computer will just take so much RAM then. OK. Bill "Paul" wrote in message news Bill Cunningham wrote: "VanguardLH" wrote in message ...

Well see the thing is, some computers want the smaller stick in the first slot. Others the second. Some don't seem to care. And I believe sometimes you don't mix an old stick with a newer one. Bill |
