Okay here's my problem, I have 128MB RAM/PC100 Mhz stick installed. Can I take out the 128MB/PC100 stick and install two 128MB RAM/PC133 sticks? Or do I have to stay with the 128MB/PC100 SDRAM? I also am running Windows 98SE and heard that more than 256MB RAM would cause problems. Ideally I would like to run three 128MB RAM/PC133 sticks.
you shouldn't have any problems using pc133, but if the fsb is only 100mhz then the ram will run at 100mhz instead of 133. on that note, there's a good chance you'll be able to use the existing pc100 and the new pc133 and not run into any problems (as long as you leave the fsb at 100mhz ... if it's even 100mhz).
384mb should be fine, though windows starts to have (fixable) problems around 512mb and 1gb.

yes, i still use the i386dx-33.
no, i wouldn't trade it for a pentium iv.

Thanks Chris... Just one question. Can I leave the 128MB/PC100 stick in place and add two 128MB/PC133 sticks in the remaining two slots? It sounds like that is what you are saying...bear in mind I'm somewhat a newbie.
Technically,
Mixture of the two types should still work, unless there is design compatibility issue(s).
Tested memory modules specifications at the following, LINK.

Cheers.
If the 128MB PC100 is the factory [read computer manufactors] memory, I'd take it out. But, i have had them work with no problems also. If that is original Compaq, remove it.

as shinma and train stated, and as i stated previously, there's a good chance that you can use the old memory with the new. the only way to find out for sure is to try.

On my Compaq 5360, I replaced the Compaq Ram even though it still works.

I think the 128MB/PC100 is OE since I bought the puter new, so it stands to reason it is. Here's what I am going to do, go and buy 3 128MB/PC133 sticks, take out the OE stick and see if the PC133's work. The sticks are made by K-BYTE at $34.99 each.
two more questions,,, what is fsb and how do I determine what the fsb is on my puter?
thanks to chris wolf, train, shinma and greengoose1
will post back results tomorrow.
fsb = front side bus. Mobo manual will have the spec.

Thanks Train https://discussions.virtualdr.com/

I must be a newbie, I bought a Compaq!
Okay I installed the 128MB/PC133 sticks in slots 1 & 2 with the OE 128MB/PC100 stick in slot 3 which (by the way is where I found it upon opening the case?) not sure if it matters but I would think slot 1 would be the logical spot. So far no problems so I am going to put another PC133 stick in tomorrow so long as there are no problems until then.
Thank you all for your time and patience! https://discussions.virtualdr.com/

I just installed 3 128mb pc100 CL3 sticks of RAM, at the reccomendation, of a site at http://www.crucial.com I just put in Compaq Mod# 5245 Presario and they showed all the RAM that that model required, the Total you could put in and I don't believe that PC133 CL2 was offered. I believe they said that this model would not benifit from anything over PC100 CL3. Anyway it's Micron RAM and I learned alot about how RAM works,so it might be worth a look, just to learn a little more how RAM works in your Computer. Marturo

We can fix anything if we try hard enough.
Marturo...I had the same reservations as you, after doing some research, talking to the folks here, and going to crucial.com, I decided the 128MB/PC133 sticks probably would work so I installed them and have no problems so far. Here is what crucial has to say:
Quote:
Which speed and memory technology should I buy?
In general, you should match the speed and type of memory technology that is already in your system. If you don't know exactly what type of memory you currently have, don't worry; any of the modules listed in the Memory Selector™ for your system should work fine.
Common types of memory technology include fast page mode (FPM), extended data out (EDO), synchronous dynamic random access memory (SDRAM), and double data rate SDRAM (DDR or DDR SDRAM). Most systems will accept only one type of memory technology. (The very few motherboards that can accept more than one type of memory will only allow you to use one type at a time.)
Memory speeds are written in different formats depending on the type of memory technology your computer uses. FPM and EDO speeds are written in nanoseconds (ns). SDRAM and DDR speeds are written in megahertz (MHz) or with a "PC" rating.
It may seem confusing, but faster memory will NOT necessarily make your system faster. Your computer will only run as fast as the "slowest link" in your system, so you can't speed up your computer by adding faster memory. The way to make your system faster is to add more megabytes (MB) of memory.
Here's a rough guide to relative memory speeds. Remember, it's best to match the memory that is currently in your system.
Crucial.com
Here's what crucial says about your model:
I am by far a tech but I have noticed my harddrive doesn't cackle anymore. It could very well be because I have more memory, more than likely it is. Is my pc faster? So far I notice some improvement in tasks performed, but that was not my entire goal. Mainly I wanted more memory so my harddrive did not have to work harder than it should. So I took a chance and so far so good. I would like to thank you for your input though, I think it's great their is a forum like this so we all can learn and share our thoughts and experiences.Quote:

The difference is not using the virtual memory as much. And as you found out it does help.
With 384MB ram I still set my virtual for a minimum of 150MB and let windows set the max.
Now to help matters along I also use Powerful PC
Between the two, I have changed a 28 minute graphic rendering from 28 minutes to 1 minute 30 seconds. And I like that idea real well. https://discussions.virtualdr.com/

Train, if I go into:
My Computer>Properties>Performance tab>Virtual Memory> windows is managing virtual settings right now. If I tick the "Let me specify my own virtual memory settings" it reads:
Hard Disk: C:\10449MB Free
Minimum: 0
Maximum: 10449
My questions are, is this where I need to change my settings? And if I set the minimum to 150MB how do I let windows set the maximum? Or do I go into the registry to do the changes?

You are in the right place
And if I set the minimum to 150MB how do I let windows set the maximum?
Yes you type in the 150 in the minimum area, but leave the max alone. Make NO changes in the Max area
Or do I go into the registry to do the changes?
Hope this clears things up for you.

Train I thought my instincts were right and yes, you did clear it up except now I have another question. I did the changes, restarted my PC and went back to the virtual settings and noticed that "Windows is managing my virtual memory settings" is ticked and the hard disk>minimum>maximum settings is grayed out. The settings did change as follows:
Hard Disk: C:\10449MB Free
Minimum: 150
Maximum: no maximum
Is this normal? There is also a box to tick to "Disable virtual memory settings" which I have left alone.
p.s. My Systems Resources did increase by 3%!!! https://discussions.virtualdr.com/ I'm going to try the PowerfulPC tip you posted which means I'll probably be a royal pain in the .... but first I better re-read the link cause there is alot to of info to absorb. Thank you Train for your help and patience! https://discussions.virtualdr.com/

You are welcome to the help and glad to be able to assist you. I reread that a good number of times myself. Also, WhitPhil posted a good explanation of how that stuff works.
Yes you are reading the same informantion as I do and that is normal.
Remember when you started it said 0 in the minimum box. Now your minimum is 150MB, but in system.ini, [386Enh] MinPagingFileSize line it might read a little different.
Mine reads MinPagingFileSize=153600 {which is in K} so that is 156.6MB.
Thought I'd point that out if you see it so you would not panic. Again nothing to worry about.
That disable box, leaving it alone is a very good policy.

Just went into the system.ini, and my [386Enh] MinPagingFileSize reads the same 153600 but wouldn't it be 153.6MB https://discussions.virtualdr.com/ Darn typos...hehehe! Again thank you and hope I can return the favor in the future.

Powerful PC. Forgot about that. I miss reading the VV posts. Will work for XP or does it need to be modified for XP?
