    PC reading wrong DDR2 memory size


    Hi,

    I've recently replaced a defective memory stick in one of my PCs and now it is reading memory size wrongly. The mobo is a POS-MIQ35AF (skt 775), CPU is a C2Q 9550 (2.83 GHz) and I have 4x2GB Kingston KVR DDR2 modules. Instead of reading 8192 MB it's reading 8064 MB. When I left only 2 sticks it reads 4032 MB... The system is working normally with no BSODs, but it's quite wired...

    What may be causing that?

    What does it show in resource monitor under memory tab? It may be subtracting hardware reserved.

    Sometimes graphics cards use a small part of memory.

    Yes, I know, but BIOS shows incorrect memory size before loading anything else...

    ~edit~

    What is interesting is that I ran extended memory test for hours without a single error...

    Yes, BIOS reports the memory without the memory used by the graphics card. Check your bios for the size reserved by the internal graphics.

    I'm using a discrete graphics card. The integrated graphic chip is disabled. Go figure...

    Also try checking maximum memory setting. +R msconfig, on boot tab click advanced and make sure maximum memory is unchecked

    Thanks you all.

    I've just found my missing 128MB of memory. It's shown as hardware reserved in Resource Monitor, but I don't think it's related to video, it's something else... Anyway it's curious that BIOS reports it without the reserved memory.

    Glad you figured it out. Hardware reserved can be a graphics card, sound card or other things.

    Enter +R, then enter "devmgmt.msc" without quotes, select Resources by Connection in the View Menu, and expand the Memory node

    do you run any virtual machines? My win 10 virtual installation reserves that 128 MB for video memory. And i also have a Sapphire Radeon R7 260x discrete gpu.
