Re: Windows XP x64 and 4GB ram

Tech Tip: Click here to run a free scan for Windows Errors and optimize PC performance

yes, I use 4 x 1GB DDR2 667 DDR2 ram

so they are pairs, :)

and:
the BIOS POST screen display 4096 MB,
memtest86+ test all OK,
and CPU-z report 4096MB memory installed on window xp(32bit).

but Windowx xp x64 crashed.

BTW:
I've typed err, it is "Memory Hole Rempping", not "Memory hole Mapping"

You have to add memory in matched pairs, since it is DUAL
CHANNEL

Number of Memory Slots 4×240pin
Memory Standard DDR2 800
Maximum Memory Supported 16GB
Dual Channel Supported Yes

| Ok, when I have 2G ram installed, Windows XP x64 works
very nice for 1 years.
| Today, I buy additional 2GB ram and install them to my
computer.
|
| After that, problem begins:
|
| In BIOS:
| set "Memory hole Mapping" disable, BIOS and windows XP x64
report only 2.5G
| ram, but runs well.
|
| set "Memory hole Mapping" enable, BIOS reports 4G ram,
Windows xp x64 crashed.
| I reformat my RAID and run windows xp x64 setup, when it
copy files from
| CDROM, it report copy fail.
|
| I have tested ram by using "memtest86+" and all 4G ram no
problem.
|
| With a search, I found that someone alse have this
problem, for example:

| So, how can I resolve this problem?
