Upgraded memory from 256MB to 512MB

Upgraded memory from 2x128MB to 2x256MB DDR400 CL3 and it now hangs up
during boot. It will run Win98SE safe mode. Also runs fine under
Windows 2000 & ram tests fine. Bios reads 512MB.

When I remove a 256MB card, it boots under Win98SE. Either card. Both
cards test good. I am stumped.

Win98 should have no problem with 512 megs of RAM

Give this a try:

in the bios, underclock the RAM...try setting it for 333mhz (or less)

In very rare instances, I've had to underclock RAM slightly to get a system
to work properly.

You probably need to write into SYSTEM.INI
Maxfilecache=524288

I thought this would be a problem on systems with *more* than 512 mb.
Not with systems with 512 mb.

Anyways, try the following:

Use the MaxFileCache setting in the System.ini file to reduce the
maximum amount of memory that Vcache uses to 512 megabytes (524,288 KB)
or less.

For additional information about how to use the MaxFileCache setting,
seek the article number below to view the article in the Microsoft
Knowledge Base: Q108079

http://support.microsoft.com/default...;en-us;Q108079

32-Bit File Access Maximum Cache Size

Use the System Configuration utility to limit the amount of memory that
Windows uses to 512 megabytes (MB) or less.

utility, seek the article number below to view the article in the

MORE INFORMATION

Vcache is limited internally to a maximum cache size of 800 MB.

This problem may occur more readily with Advanced Graphics Port (AGP)
video adapters because the AGP aperture is also mapped to addresses in
the system arena. For example, if Vcache is using a maximum cache size
of 800 MB and an AGP video adapter has a 128-MB aperture mapped, there
is very little address space remaining for the other system code and
data that must occupy this range of virtual addresses.

I added Maxfilecache=524288, no change.
I updated the BIOS to the lastest version, no change.
Running low on options, I ran the Win98SE setup again. Whatever was
lacking, the setup program fixed it.
Thanks for your help

Strange, but it must have been something in the BIOS that didn't set right.
Perhaps the ram speed?
You don't really need that line above for only 512MB, but it will not hurt
anything.
In fact, it you ever decide to increase your ram again, that line will be
important.
PS: If you do increase your ram again, I would definitely go into the BIOS
again to make sure everything is OK and then select
" Save and Exit" before booting into Win98Se.
Glad it's working for you now.

PS: Did you notice any extra speed or performance since adding the extra
ram?
