RAM Count Different In Windows An BIOS

By Dualinlinememorymodule ·
Why Is Windows Saying I Have 384 DDR RAM
When The BIOS Says I Have 512

And I Just Ran A Pitstop Test And It Says The Opposite

RAM installed 384 MB
Windows RAM 512 MB
Total RAM slots 4
Available RAM slots 1
Max RAM module size 32 MB
Memory Type 128+128+128+00;|Unknown|;T5
Level 1 Cache 128 KB
Level 2 Cache 256 KB
Speed Rating 3024 MB/s (133% of 19509 similar)

What The ****

I Took Both Rams Out And Placed One By One In
And Booted
And Both On The Self Count As 256 In BIOS And Windows

When I Put Both 256 Blocks In It Says 512 And 384
I Am Confused I Dont Know Whether Windows Or The BIOS Is Right

and pitstop says i have 4 ram slots which is correct 2sd and 2ddr
but says my ram count is 128+128+128+0
But Its Actually 256+256

Now I Have 256+256=512 In To DDR Slots

I Am Asuming Maybe Windows Cant Interupt DDR
as well as sd so theres a conflict however
im not fully sure

Plz HeLP Me'

Thanx DSI INc

please check whether all the RAM are of the same type for eg. some ram are 128 PC 100 and some are 128 PC 133. This makes the ram count different. check one by one. u will find the faulty ram.

which version of windows are you running? Does 98 and some others have problems with 512 MB or more? How long ago did you upgrade the RAM? Is there another PC available for testing the sticks? Do you run a virus scan on a regular basis? Is yourBIOS up to date? Any of these or more could be a problem, and as always, make sure the RAM will work in your MB, not all RAM will work in all MB.

Hope this helps.

Which version of Windows? W9X [including ME] has this problem with memory at or above 512MB. I've had the same problem with these versions of Windows. W2K,NT,XP can handle the larger mem size but W9X just has this problem with it.

I have a few ideas for you.

Does the motherboard have on-board video?
If the BIOS hard configures some RAM for video, it will not show up in Windows.

Check the motherboard manual / mfg for memory limitations.
Often, if you have a large memory module, you are limited on the size of the additional RAM modules.

Are the DDR DIMMs the same?
You may have an addressing issue between the 2 modules that is blocking 1/2 of the 2nd DIMM.

Next, depending on your version of Windows, there arestatements that can limit the amount of RAM that Windows uses.

In NT, W2K, XP the statement is in the boot.ini file.
You are looking for the line maxmem=

In Windows 9X, the line is in the system.ini file.

Look for the following line in the[386enh] section of the System.ini file:

MaxPhysPage=XXXXX

This limits the amount of physical RAM that Windows can access.
