memory upgrade problems

[damien666]

Evenin all,

As of a week ago I was running 256 megs of RAM. (2 sticks of PC133 128mb sticks). I really wanted to upgrade to 384 (my board has 3 available slots). So i purchased another pc33 kingston 128mb stick and installed it in my board. The upgrade was a success needless to say, but I'm now noticing ever since I installed the additional RAM, more often than not it seems like my system is running much slower and blue screens much more often. Any suggestions on why this is happening is appreciated. Thank you

Some motherboards don't like having all memory slots filled. Some motherboards don't like having certain memory slots filled. Also some motherboards just don't like certain memory sticks. I had a motherboard that hated Micron memory.

In addition the motherboard may be running the memory at CAS2 timing. The Kingston memory may be rated for CAS3 and be problematic at the faster CAS2 setting.

What to do: trying shuffling the memory sticks in different slots. See how fast memory is running by checking the memory settings in bios. Change memory settings to slower speed. Take out Kingston memory and see if problems go away.

What OS are you running? Did you resize your swap file? Don't know why, but W2K still does not dynamically resize your swap file when you add RAM. :rolleyes:

I doubt this is causing your blue screens, but it sure doesn't hurt to check.

Jeff,

I'm currently running Win98 SE and close to upgrading to 2000. What size should I resize my swap file to?

JeffBX meant if you are running Win2k already and add more ram, WIn2k will not resize the swap file.

[Jeffbx]

Right. Under W2K if you add more RAM, the system will tell you what your swap file size SHOULD be, but it won't adjust it for you. You have to remember to do it yourself.

To answer your question - in 98, let the OS choose your swap file size for you. In W2K, set the minimum to whatever the OS recommends, and the max to 1.5 - 2x the minimum.

need help,

like many of the persons posting in this BBS i also have problems when i upgraded my memory.

I have a kk266 mobo, 1Ghz AMD TB, with 256MB RAM. 32MB GTS pro video card. OS win2k SP2

when i had the 256MB RAM stick, everything was fine, and my PC was rtunning somoothly (i havent overclocked yet but i want to, if i get the necessary information).

the problems started when i upgraded my memory. i bought another RAM stick, 512MB this time, and when i used both of the RAM sticks, win2k will boot but if i played "any" 3D game..Black and White or Crimson Skies.... the system will cancel the application and/or rebbot by itself.

i took the 256MB RAM stick out and everything is normal once again. i have read that some motherboards require ECC or Registered ECC dimms if you use more than one stick. Has anyone else heard this?

i think i read it in another BBS but i am not sure where?

has anybody aout there have any idea on how to fix this problem?


thanks in advance
