(OT)Memory
 

If I have a system with pc100 sd ram can I add pc133 sd ram without problems, I know that if the system works with 100 the 133 should slow to 100 but will it make the system crash????/

Re: (OT)Memory
 

you will have to check your mobo documentation to see if the mobo will accept the the two different speeds. Usually the answer will be no. As most times the memory has to be paired

Hmmm...no Doc for MB was a freebee to me (was faster than my system) I have 3 slots and have them stuffed with 64meg ea for 192 total but want more http://forum.shrapnelgames.com/images/icons/icon7.gif thanks http://forum.shrapnelgames.com/images/icons/icon7.gif

Re: (OT)Memory
 

what is the mobo... perhaps i can find the doco

That I do not know, is an older HP system, I am not at home at this time so I can not find out till I get there.

Re: (OT)Memory
 

I'd give it a shot. Just be sure you can take the memory back.

I've got a few systems with 100 Mhz memory that have 133 RAM in them with nothing worse than an occasional message in POST (stupid Gateway system...).

Re: (OT)Memory
 

As Loser said, just give it a try. Based on the comcrap....I mean Compaq systems here, it will work fine.

Lets see 128 meg for 30.00 not to bad with 1 will give me 256 cooool http://forum.shrapnelgames.com/images/icons/icon6.gif

128 Mb SDRAM PC133 RAM - $9.99

At that price, you should be able to buy 2 and be confident of a matched pair. However, I've never had any problems with mis-matched speed for RAM (as long as I use the minimum). Only have had problems with type of RAM ie. ECC, etc....

You shouldn't have a problem, I would take out the 100mhz memory, just in case. What OS are you using? If it is 98 ver's then going over 512 mb wont help and might give you glitches (I can't remember exactly why, something about 8/16 bit processing I think). I don't remember hearing any issue with ME and memory. with Win 2K and Xp the skies the limit (err the MotherBoard is http://forum.shrapnelgames.com/images/icons/icon10.gif )

11 bucks a stick here: http://www.dvcentury.com/Merchant2/m...ode=88-130-120

Re: (OT)Memory
 

i just looked at what i was absent mindedly doing.
port 1: sd 100mhz 64mb
port 2: sd 133mhz 64mb
port 3: sd 133mhz 256mb

then i looked at the motherboard:
ports 1-2 100mhz , 2-3 133mhz
by what the compaq sit said your right all 3 ports will run at the slower speed.

Re: (OT)Memory
 

What speed is the cpu in that system? On older systems there is a point where addressing load can actually hurt performance.

Re: (OT)Memory
 

750mhz AMD duron
bus speed i dont know

Re: (OT)Memory
