Max RAM for Win95b ?

The maximum amount of RAM that can be installed in a particular motherboard is not
related in any way to the operating system; it is a limit that is specific to the
motherboard. Whether you mobo can support 512MB of RAM depends on the
manufacturer's specs. You can check by going to www.crucial.com

That said, Win95B will work with whichever amount you install total....either 256 or
512. Anything greater than 512 will require particular tweaks to the system.
However, unless you have some specific apps that require such large amounts of
memory installed, you will not likely see a big performance difference between 256
and 512, and increasing to 512 may just be a waste of money.

What you should do is monitor you swap file USAGE for a week or so while doing your
usual work. You can use System Monitor for that...add the option to monitor "Swap
file in use". If the actual swap file usage is very low or non-existent, then
increasing the installed RAM will not accomplish anything. If however your swap
file usage averages an appreciable amount, that amount when added as RAM will
relieve the load on virtual memory.

Certain older chipsets such as the Intel 430TX have a limit where only the first
64MB of RAM will be handled by the L2 cache. However, you can still use 256 or 512
MB of RAM on such systems, because the added RAM will reduce or eliminate the usage
of the swap file, leading to a huge increase in performance even though the uncached
RAM may cause a very small performance drop.

With Win95, it is very helpful to set a MaxFileCache in the [vcache] section of the
System.ini file, especially when installed RAM amounts go up, lest the swap file
grow too large because vcache doesn't shrink quickly enough. With 256MB RAM
installed, I would start with a setting like this:

[vcache]

MaxFileCache=32768

Watch you swap file usage and see if the setting helps, or needs to be tweaked.

Hope this helps.

NOT TRUE!! I think this myth comes from the fact that a lot of
motherboards built in the Win95 era couldn't cache more than 64MB. You
could still use more than 64MB, up to whatever your motherboard
supported (they didn't support 4GB in those days). Access to memory
over 64MB would be slower than if it were cached, but still a *lot*
faster than the virtual memory file on your disk!

I had no idea Win95B cannot use more than 64 Mb ram. I have the option
of obtaining 256 Mb ram for free, that would be compatible for this
mobo, and thought it may help. Apparently not.

Thanks.

The mobo should be able to support it, by this spec:

Okay, thanks. The extra ram would be free, so I thought, it may help.

Okay thanks. I will set the monitoring of the swap file up, possibly
it can o/p to a file, for later review. (Actually, today the W95b
computer hung, first time in ages, got the blue screen and some msg
about waiting ... ).

The details on the chipset are:
VIAŽ VT82C693A Chipset
VIAŽ VT82C596B chipset Chipset

Okay, thanks. There is no value at all for "[vcache]" in system.ini
at present, so I will add the value as you suggested.

Thanks.
 >> Stay informed about: Max RAM for Win95b ? 

If it's free, grab it. It probably won't make a big difference for most of
the things you do, but there are always odd times when Windows suddenly
needs a lot of RAM, and having the extra there won't hurt.

The chipset will support that RAM, but the motherboard might have its own
rules, so be sure to check. Note that you might run into problems if the
new RAM isn't the same type - while it's technically possible to mix RAM
types, in practice it sometimes doesn't work.

Okay, I will try and see what type of ram is installed now, and what

 >> Stay informed about: Max RAM for Win95b ? 

Sandra's report doesn't tell you much regarding the actual RAM stick. Download and
install Everest Free Edition and it *may* supply you with more detail about the
installed RAM:
http://www.majorgeeks.com/downloads9.html

http://www.majorgeeks.com/EVEREST_Free_Edition_d4181.html

In Everest, look on the left and expand "Motherboard", then select SPD and look on
the right. If the installed memory supports SPD, it will list details of the
module. Older RAM won't show anything, though.

Also under "Motherboard", select Chipset....it *may* provide info on what is in the
RAM slot.

Yes, I've heard this 64MB 95 limit may not actually be true, but
many apparently knowledgeable sources say it is. I once looked
for a **definitive** answer (if there is any such animal in the
computer zoo) and I think I found confirmation of it on a VERY
respected site - sorry, can't remember which. It's been years.

All I can say is I have been running a 95B machine for 9 years
with 64 MB RAM with RAMpage installed (about 6 years ago) and it
works just fine.

Also, if anyone IS running 95, it's a fair bet they are running
it on a machine built 10 or 12 years ago.

It's sort of a moot point since from what I have read in NG's
over the last few years, me and this guy are the only two people
in the whole world still using 95. ;-#

Thanks !

You have found the definitive answer. Windows 95 does not have a 64Mb RAM
limit. In fact, whether or not this myth is repeated is a fairly reliable
way of judging the credibility of the W9x site.

OK, no info under Chipset either, about the RAM in the slots? Your RAM is too old
to have SPD chips then.....it is most likely PC66 SDRAM, but it could also be early
PC100.

RAMPage or similar)

My machine is 5 years old.

Most of the tweaks imposed by these snake-oil memory managers often do
end up hurting overall performance, such as by causing excessive
memory paging activity in order to maintain a totally unnecessary
supply of "free memory".
