System Max out

By ITTech2 ·
Ok, here is the situation:
Windows ME
AMD Athlon Processor
CPU 1135.69 Mhz
Memory 512k
Cache Level 1 data 64kb, Level 1 code 64kb, level 2 unified: 256kb

When I am doing anything, downloading, saving files, etc.. the system becomes sluggish until the task is done. I have a program that shows the CPU usage, Total Physical Mem, and Free Physical Mem,and the swap file:

Total Phys Mem 523720kb
Free Phys Mem 47684kb
Swap File Size 1573428 kb
Swap Usage 2%
CPU usage is always at about90%

Motherboard is an Epox 8kta3+
Hard Drive is 60gigs with the high speed cable connected to the Ultra ATA bus master IDE controller.

Any suggestions as to why this dogs? I've tweaked the bios as best as I can, reset to optimized settings, and get the same results. I've formated and installed Win98 SE and get the same results.

Thanks in advance

System Max out

Check out MS knowledge base article Q253912

Basically, Windows 9X/Me can have problems with more than 511MB of RAM.

This is VERY configuration dependant, with some systems working fine with up to 1GB of RAM.

Here is an excerpt from the article;

The Windows 32-bit protected-mode cache driver (Vcache) determines the maximum cache size based on the amount of RAM that is present when Windows starts. Vcache then reserves enough memory addresses to permit it to access a cache of the maximum size so that it can increase the cache to that size if needed. These addresses are allocated in a range of virtual addresses from 0xC0000000 through 0xFFFFFFFF (3 to 4 gigabytes) known as the system arena.

On computers with large amounts of RAM, the maximum cache size can be large enough that Vcache consumes all of the addresses in the system arena, leaving no virtual memory addresses available for other functions such as opening an MS-DOS prompt (creating a new virtual machine).


Mysuggestion, reduce RAM to 384MB. Or, upgrade to XP.
I limit my 9X boxes to 384MB.
In fact, under some conditions, W98 works best with 196MB of RAM.

The Max Physical pages setting is critical.
It also helps to get rid of (Turn off) virtual memory.
Run Cacheman, and try the 512+ settings.
We have some of these same motherboards with 1 gig installed under WIN98SE.
Your checking the BIOS is also valid. We have had flash BIOS failures with these motherboards.
Warning! The usual 512 symptom is an error message on boot saying that there is not enough conventional memory available.
