RAM Question
 

Hi,

The other day I was upgrading the RAM in some PC's. The supplied RAM would not work as additional RAM of as a single stick on it's own.

The error was a number of long beeps - nothing on the screen / no boot.

Tried another stick of the same RAM but still the same. Tried another machine - same error.

Here's a photo of the RAM - I can see the type is slightly different - what's the significance of this? Should they be able to co-exist as the supplier claims they will.

The blue stick is the original in the PC and the green is the additional stick.

What does your board support? Some won't work.

From web
"
It might help to download the free 'Everest Home 150' system analyser from http://www.lavalys.com/products
which spells out everything to do with your machine and also gives advice on whether the memory is at optimum or not.

There is also 'Start - Run - type in msinfo32 - Press enter' and an internal analyser will pop up which gives similar tho' not so detailed info.

Memories...of the way we wereeeeee :D

It's a HP 3120MT PC - not sure of the board. Will have to go look it up...

Re: RAM Question
 

1 module is single rank, the other dual, so they are strictly speaking not identical.

It's possible your mobo will not support one of these types or doesn't like the mix.

Is that what the 1R and 2R means then? What about A0 and B0?

Re: RAM Question
 

That'll need a wiser head than mine. I recognised the 1R & 2R but I'm not enough of a tech to advise you on all and any implications.

Kymmy?

If you can go to the corsair website and run the mem checker thing on there, and that will give you a list of ram that will work with the pc.

I have used it a few times to get ram for a laptop or 2 and it has worked fine all the time.

It's the way the chipset on the dimms is arranged... They should work in individual bays but not as dual channel as they're not identicaly arranged.

A few motherboards though will even have problems with them in single channel mode though usually a bios upgrade will cure that..
