Hi,

My current system is,

CPU: 750 Athlon
MB: Abit KA7-100
Ram: Corsair 128mb PC133-16x8 SDRams-Unbuffered-CL3 (model: CM654S128A)
<website> http://www.corsairmicro.com/main/products/specs/cm654s128.html
OS: Win2k Pro
Often Uses: IE5,MIRC,ICQ,Winamp,WCommander,Warftpd, Leapftp, &amp; Games (BG2,RPG)

Ram is currently cheap, and I am just about ready to upgrade more ram. There are numerous respectable manufacturers including Corsair, Crucial/Micron, and Kingston. I have the following questions.

1.) This is the first system I have that uses SDRAM. I am familiar with EDO ram in which the rams must come in the exact same pair. Do I have to put in similar SDRAM (specs, model, etc.) without affecting the Corsair?

2.) I can always buy the exact same stick that is on there right now. Most vendors price it at about $85-above. However, I go to to www.crucial.com and find the following for about $10 less than the Corsair:

Crucial 128mb PC133-Unbuffered-CL3-ECC (model: CT16M72S4D75)
<website> http://www.crucial.com/index.asp?model=KA7-100&amp;x=16&amp;y=3

Some of the specifications on about Corsair and Crucial do not make sense to me. According to the specs, the Crucial *appears* better. Is that true? In addition, let say I get the crucial, it there going to be any problem because it and the corsair do not have the same spec?

3.) Win2k Taskmanager typically indicates my system uses about 100mb of ram. Nonetheless, I experience a decrease of speed when openning more programs. Will upgrading ram speed my system up?

4.) When will a new ram format surpass SDRAM, and thus SDRAM will become obsolete? I am considering getting 256mb rather than the 128mb. Is there a significant performance difference between a 256mb system and a 384mb system?

5.) Which SDRam do you recommend? I have never had Crucial rams. Corsair SDRAM is very reliable and works flawlessly. I did not include anything from Kingston. Feel free to add comments about it, or any other brand.

Thanks,

1) No.
2) Most probably no problem at all.
3) More RAM is always beneficial for Windows 2000.
4) DDR RAM is the next generation of memory. You should be fine with 256 on Win 2K unless you do extensive memory-eating programs. (i.e. Photoshop)
5) Crucial will suit you fine.
 
I would recommend Crucial to anybody, any day!

Get the part no ending in &quot;7E&quot;, which is CAS 2 also.
 
No point in buying the more expensive Crucial CAS2 RAM if your current Corsair RAM won't do CAS2.
 
Thanks guys.

According to what Peemo writes, a system will assume the SDRAM with the less features. So my system will utilize CAS-3 even if I put in the CAS-2 because of the Crucial.

Unless your Crucial will do CAS2 at the speed you're running despite its rating. Good chips on a good PCB will often exceed their ratings. Try your Crucial at CAS2 and see if its stable then get some more RAM to match the Crucial's capability.

Good Luck.
