RAM upgrade to 2 GB PROBLEM on T43

[babha]

First of all hi to all, as iM new here!
And i have a problem. Got a used T43 with just 512 MB RAM - so i ordered 2 x 1GB Corsair RAMs after reading, that they are no problems in the T-Models.
The problem is: the RAM-socket beneath the keyboard works proper .. i tried all the sticks inside - NO PROBLEM. But if i ad - any - stick in the second one - the computer will not boot. It starts (sound), but nothing on screen, it seems to "freeze". Is there a solution? Do i have to change somewhere i dont know or download a program or something?
Is it SOMETHING that could be done about it??!!
It doesn´t seem that the seller will take the computer back because of that ... and i actually dont believe he knew about it when he sold it.
PLEASE HELP!
greetings
Manfred

Welcome to the forum.

Sorry to hear of your trouble.

You could try 1 x 2gb chip in one slot.

Welcome to the forum.
There's nothing you can do about it, other than swap out the motherboard.
Insist that the seller accepts a return and give you a full refund.
After all, that machine is defective. Did you buy it as-is without warranty?

Just saw the post about 2GB in one slot. That's not possible AFAIK.

Many of my T43/R52s run on a single 2GB module.

Yes, i bought it in ebay .. and there You have, at least in Germany, no warranty. Actually i dont think that the seller knew about the problem, BUT .. here i am ...
His first reactions didnt look like "Oh, iM sorry, in that case .."

There has been mentioned 2 GB in 1 slot. Is THAT possible?
What kind of RAM are You using? 4200? Higher?
I was VERY surprised to read in some posts, that people mix all kind of RAMs successfully. In a German forum i got the impression that the Thinkpads are very sensible and dont take everything ...

Sorry: i read my last post ... forgot to ad: "no warranty in ebay IF YOU BUY FROM A PRIVATE PERSON ..." of course!

T43 can take 2x 2GB. OS will only use 2GB total either with 1x 2GB or 2x 1GB. PC2-4200 or PC2-5300 will work but they only work at 533Mhz, speed for PC2-4200.

Maybe you want to contact the memory manufacturer. I had a situation similar to yours and Kingston swapped my two sticks for one. I only had to pay to mail it in. $5 I think.

You can try to clean the memory slot, too. I'd try 1) compressed air, 2) pencil eraser, 3) alcohol.

Definitely sounds like a bad memory slot. The way the connector works, it's supposed to be self cleaning, but try cleaning it anyway - it can't do any harm although it's difficult to get at the individual contacts. I'd see if the memory vendor will swap the 2x1Gb sticks for a 1x2Gb stick plus any difference.
