Memory upgrade

Piusno1

I have an old computer, its pentium 3 133mhz I have already installed 1x256mb stick and 128mb stick and its working fine, but I still think I could do with more so I bought another 128mb stick to install. There are 3 dimms and I think 512mb is the max for the processor i have, but when I put the new 128 stick in the computer stalled, there was no signal at all, I took out the older sticks and put the new 128 stick in it booted no problem. But when I had all 3 sticks in no such luck,
So can anyone advice me to what im doing wrong.
Thanks all

Thankfully you are PC133, the slighly older PC100 was problematic on many DELL pc's (intel chipset thing other PC brands also affected) so matching was critical - PC100 was not a guarantee it would work.

You may have a timing issue - in case there are speed differences in the ram - try each of the DIMM's on their own to make sure they are ok, then put the slowest one in the first socket and get the BIOS settings for it - used to work on older PC's

CPUZ is a utility that will give you more info on the memory. and http://www.shop4memory.com has a utility where you can type in the make/model of many pc's to get an exact match ( of course you can buy it some where else ) it might even list the one you have

Try Crucial.com for decent prices on memory also, they have a tool that can scan your machine. Shop4memory are very good also.

Sometimes ram sticks of different brands refuse to play well together. A friend of mine once had to deal with this fun thing. I think he went in to the BIOS and set his currently working ram at CAS 2. When he popped in the new troublesome ram, it started working! So try lowering or increasing the CAS latency and then put in the new ram and see how it goes.
