Help memory problems ;-(

[Vaughn]

I have 2 PCs. One a homebuild with 4 memory slots. 2 are for SDRAM Dimms. I
believe DDR, they only have 1 location notch in each slot. The other 2 have
2 Notches in each slot.

One of the First slots has a single 512MB DDR memory chip, and all is OK.

the other PC is a DELL, and this has 2 slots similar to the ones being used
in the first PC. this Dell has one 128MB memory module in one slot.

I have just purchased another 256 MB module but this will not work in either
the DELL or Homebuild PC.

When used in the DELL the screen has painted, und unpainted strips on it
when the new 256 module is used.

On the Homebuild nothing works with the new 256.

the other 512, and 128 work in both machines.

The only difference in the 2 working, and new un-working module is that the
old working ones are 2100, but the new one is 2700.

Is this the problem?

And what does 2100, and 2700 mean as the older ones are 333MHz, as so is
the new module?

I'm sure the answer is very obvious, but if you could be so kind as to point
it out I'd be most grateful.

Thanks in advance Vaughn

Try it in someone else's system.I'd suspect a faulty module but check

Did you put the larger chip in the #1 slot?

 

[Vaughn]

Did you put the larger chip in the #1 slot?

Yes always put larger in first, but still no good. thanks for the reply,
anything else you can think of please please forward.

many thanks Vaughn

Trying this later when I can get to my mates.

This link was really good, thanks.

Gave a lot of info, and from what I can make out all seams the same with
both the info on the link, the old Modules, and the new non working one, so
pretty sure now its a faulty part.

many thanks for hat speedy reply.

Have now also tried it on another machine, still no good, so suspect this is
a faulty module.

Still Any idea what the 2100, and 2700 markings mean?

Thanks Vaughn

2100=266 MHz
2700=333 MHz
3200=400
3500=433
3700=466
4000=500

If your modules are marked differently , suspect the modules.

ACE many thanks for clearing that up

Higher speed modules should run in slower motherboards (ie- backwards
compatible). The important word in that sentence is 'should'. At the
minimum I always try and match the speed of my DIMMs to each other
(haven't had issues running 2700 in a 266 board, but I don't want to
tempt fate by running 2100 and 2700 modules in the same board, even
though there *should* not be a problem with it).

I'm going to die rather sooner than I'd like. I tried to protect my
neighbours from crime, and became the victim of it. Complications in
hospital following this resulted in a serious illness. I now need a bone
marrow transplant. Many people around the world are waiting for a marrow
transplant, too. Please volunteer to be a marrow donor:

Download CPU-Z, it will ID the existing memory modules and show the
speed settings.

That's what I thought, they should be backward compatible, but after it
didn't work I tried it on its won, and still nothing, so taking it back to
see what the shop says. There pretty good so all should be OK.

Thanks very ,much for the help, and totally agree, will try to keep all
modules the same from now on.
