How to add memory to your PC |
|
|
Plan a) Add the extra memory; continue normal use.
Plan b) Add the extra memory and test it with
http://www.memtest86.com/#download0
I just tried Plan a)
It cost me a week of frustration and an XP clean install (because I
did not know about plan c) )
c) Start / Run / msconfg / General(tab) / "system restore".
Cheers
Robin

More experienced (meaning having waisted too much time)
users buy a machine with a final memory configuration
and never open the machine for upgrades/improvements.
Juist add the week's worth of time and nerves to the
RAM configuration of the next machine.

Winders 9x had a 64 MB limit built into the OS. It never saw the new
RAM.

I didn't knew that adding memory could cause those effects...
I have upgraded from 64 to 128MB (4 x 32MB EDO, IIRC - this was a while
ago and I can't open the case right now) - no problems happened to my
Windows 98 installation.

Re: How to add memory to your PC |

I was never aware of such complications coz of RAM upgrades...
Done it plenty of times.. No problems at all..
Only issue that might come up is when playing with timings in the BIOS... in
the worst case bios wont boot and have to clear the settings... Thats still
only 15sec extra work! |

Re: How to add memory to your PC |

I used to repair a thing called the BBC Micro in the early 1980s. I
did this for about three years, about 5 to 10 of them per day.
Memory failure was extremely rare, even then (it used 16K x 1 bit
DRAM, 32 of them), maybe one machine in a hundred.
If one BBC machine per fifty failed in the first two years, then that
made memory failure 1 chance in 10000 per per year.
Only a few years earlier memory failure, RAM and ROM, was very common.
Nowdays I expected perfection more or less so when one of my brand new
2.5V 184pin 256MByte cards (I lovingly caressed chassis,
anti-static-bag while removing and inserting RAM the while)I never
expected failure at all.
(Evidently the manufacture does no testing because that would scuff
the gold edge connectors.)

Re: How to add memory to your PC |

Where did you get such a daft idea as that ?
Using Cacheman I get the following report under win 98SE
Total memory 220 M
Usage 148.8 M
Free 707.M
Win 98 won't be upset by adding memory anyway.
Only XP has issues with playing with hardware. Should be fixable by asking
microsnot for a new license number

Maybe I heard that it just won't allocate more than 64 MB per
process. It was discussed here before and I don't remember it all.

Win 98 has trouble talking to more than 512 M IIRC.
I recall a 64M adressing space limit for old ISA expansion cards like SCSI
controllers.

It happily uses it up quite easily. See above. That was 70.7M free btw - lol !

Maybe you're thinking about Windows 3.11 [1] or 95?
I have a friend with 98SE and that uses a 750MHz AMD Duron with 384MB
RAM.
[1] Actually, it was a MS-DOS limitation in HIMEM.SYS and EMM386.EXE.

DOS programs had a limit, too. And the whole OS was loaded in *just
so*, as well as the slots and all. They left room for TSRs somwhere
and a way to use himem and cousins to optimize the whole thing in
the startup files. All programs loaded at addr 0x00 or 0x100
depending on whether they were sys, com, or exe. It worked.

Yeah, but that doesn't show how much each process is using like task |
mgr does.
I got the info from an experienced coder. I'll drop in on him
sometime.
Anyone out there running 9x that can code a 128 MB malloc() and fill
it up?

Only trouble I've ever had with new memory in W98 or W2K was with
socketry connections on a new MB. Needed scuffing to make contact.

IIRC, there is a disk-cache issue in Win9x that creeps in at 512MB.
There is a registry fix for this, I believe.

ISA cards can't address more than 16MB (only 24 address bits). Many
chipsets used with early socket-7 processors couldn't cache more than
64MB. More memory would actually slow the system down due to the way
Win9x allocates memory. Perhaps that's the "64MB limit" you remember?

That's only a problem if you are doing DMA from an ISA card. The OS would
have to map it to the lower address space and then later copy it to its
final destination. However, how many people run a ISA disk controller
any more? Usually the only ISA cards you ever see floating around are
modems and sound cards. On ancient systems with an ISA disk controller
their memory capacity doesn't allow for more than 64M. |

That's the point. Without needing DMA there is no limitation.

Sure.

No one. It's dead, Jim.

|
That makes no sense. If you're double buffering there is no "64MB
limit". The buffer can be anywhere in memory since the processor is
moving the data from under the 16MB line to above.
