Physical Memory greater than 64mb (5 posts)

I have read, heard and indeed experienced a slow down in applications such as Peachtree and Office when memory is increased above 64mb.

It appears that W98SE does not handle memory above 64mb efficiently although Microsoft claims one can use up to 512mb.

Is there a fix for this?

Re: Physical Memory greater than 64mb

Windows 9x can Use RAM up to 512 MB, but you don't actually get any more performance if you put more than either 128 MB of 256 MB in it. Put 256 MB in it and it actually runs slower.

Some very old motherboards have limits on things like DMA addressing and CPU caching that mean anything above 64 MB runs slowly. But that's not the fault of Windows. And it is only with very old motherboards.

Re: Physical Memory greater than 64mb

The only fix to this problem is to use either Win 2000 or Win XP. Those 2 OSs were specifically designed with that in mind and they handle memory very well up to very large amounts.

If you have W98SE or ME then there is nothing you can do about this issue other than upgrading to one of the 2 OSs that I mentioned.

Gordon,

Thank you for for prompt reply, but I am still somewhat confused so I will rephrase:

1. Motherboard TX531, with Cyrix 6*86MX-PR200 and AMI Bios 1996 V1.01(R). Question what is the max RAM I can put in before it degrades.

2. Motherboard Aopen MX36LE-U With Celeron 900 and AWARD BIOS v6.00PG.

Question: what is the max amount of memory I can put in before it degrades?

SAMSUNG IS QOOL :))
