RAM Problems

By Itchy ·
I'm running Windows ME,with an Asus MB,Pentium 111 933 chip,Decided to upgrade RAM,from128mbs, to 512,But PC would not recognise other RAM chips.Removed all,installed one at a time, ran Norton Utilities to check each RAM,in slot one, all proved OK,reinstalled all, still would not check out.BIOS aknowledged 512 mgs, but PC was VERY slow, and when Norton Utilities was initiated, RAM would not pass test.Swapped two 128 chips for one 256 chip, installed, worked/tested ok, installed another former 128 chip, would not test ok, PC slowed down.
What can I do, to get 512 mbs installed and running correctly ??????

Are your memory sticks the same type/speed? Check out the following Asus site for tech info about MB and RAM compatibility issues

as you already found the dimms are all ok individually,your problem my be your dimm slots are dirty or the second slot my be defective.
or your dimms are from different manufactures causing compatibility problems.
try cleaning your second slot & taking all your memory to a local PC store & have them check them all together.if they all work together for them, your dimm slot is cooked & nothing you can do about it unless where you bought it will replace.

also NORTONS not the best program to test your memory with.
I used to have a link to a site where you could download a good memory tester but I've seem to have misplaced it perhaps someone else reading this will reply with the link.

There are different kind of memory, depending on vendor or speed, some of them are 66, others 100 and the others 133, as you have a P-III you should have 133. Make sure all of them are the same speed. The other detail is that some mainboard supportsup to 256 Mbytes ram, I'd suggest you to go to www.asus.com and find out the specs. of your mainboard and see if it could support 516.
If you give me your Mainboard model maybe I can help you a little further, I can tell you that the PB3-BF supports 512, I have it and it works just fine.
Good luck,
@lberto

Your original 128mb of memory may be PC100 and the new memory PC133. Try installing the 256 in the primary bank first followed by the 128's otherwise do the reverse. The order in which the memory is banked can be the problem, especially if not the same speed.
Hope that helps.
