Weird problem, windows doesnt see all my ram ?

[Iccanui]

Its wierd, ihave 2gb install, it shows in the bios, i shows in the system summery, but when i look in the task manager it seems to be paging hard after the limit, which in the general system tab is listing it as like 960mb.

A little info about my PC. Thnx for any input.

Shared RAM for video output? Maybe one of them isn't seated properly? IDK???

 

[Iccanui]

ha, that was it. It was sharing the memory with the onboard video thats not being used. Some how sharing it limits it to 1gb. i turned it off and it told me i had 1gb then found a pci memory controler. Rebooted and now i have 2gb.

your a genius sir !

 

[CDC Mail Guy]

Really? Damn, that was just a guess! Glad I could help

 

[Lord Evermore]

That's...odd. There's no reason I can think of that it would disable a second gigabyte just due to having memory sharing turned on. It was obviously using 64MB for the video (960+64=1024). I also don't see why it would suddenly find another memory controller.

What mainboard is this?

 

[jackschmittusa]

He may have reset the "AGP apreture" and gotten the ram back. Had an Asrock board do that to me. Set it at 256mb, and 1 mb ram would not show up in Windows. Changed it 64mb, viola! 2mb in Windows.
