Title: Windows 7 x86 reports memory wrongly Post by: dishwara on June 06, 2011, 05:00:47 AM I was aware that windows x86 only supports up to 3GB RAM even if you have more RAM installed.
I have 2 PC, in one PC, 2*2GB RAM is installed & In another PC, 1*4GB RAM is installed. I am suing windows 7, 32 bit since it is released & have seen my memory in Mycomputers->properties that windows shows, 4.00GB (2.97 GB usable). I also tried tweaks which enabled x86 to use up to 128GB RAM. But now after some updates & also after sp1 update, RAM in BOTH system shows 4.00GB(2.00GB usable). First i thought 1 RAM was fault, but not now, coz another PC has only single piece 4GB RAM & half of it can't go bad physically. I uninstalled & reinstalled & again uninstalled SP1 & also most of the updates prior to SP1. But still, i can see only 2GB RAM instead of 2.97GB RAM in both my PC. Also, interesting thing is i never saw windows rounding up & showing. Instead of 1.98 or something, it shows exactly 2 GB RAM usable. Anyone using Windows 7, 32 bit(x86) also faces similar problem? If not can you please give me your screen shot of installed updates, so that i can compare & find what update causing this STUPID behavior of windows.

Most hardware devices require address space for their memory. For the most part, this is insignificant, but on a video card there is often 512MB, 1GB, or even 2GB of address space required- this cuts into the 4GB originally available.
I'd guess that when you went from having about 3GB free to 2GB free you either added a 2nd 1GB card, or a 2GB video card to your system. Title: Re: Windows 7 x86 reports memory wrongly Post by: dishwara on June 06, 2011, 06:17:20 AM Thanks.
Seems, exactly the same as you mentioned. I had only one 1 GB graphics card before, & now i added another graphics ward with 1GB. 2 cards in my PC now, Zotac 9400GT 1GB & Sapphire HD 6870 1GB. |
