Ram issue

I've had a custom built computer for a couple of years now.

It has a MSI 848P Neo-S motherboard. 2 green coloured ddr ram slots (which are occupied by 2x256mb kingston ram) and another unused purple slot. The purple slot is exactly the same shape as the previous green ddr ram slot (yes, including the position of the knob thingy). Only its purple. It looks like it'll fit an ordinary ddr ram stick. but im not sure. Any ideas what it is?

And "if" it is a ram slot.. Anyone see any problems with adding an extra 2gb ram stick to it?

Thanks in advance

According to both Kingston & Crucial there are two slots . The max is 2 gig as a combination of 2 one gig sticks per slot
It takes PC2700 or PC3200
So it looks like you cant add the 2 gig module

Are you sure thats even the mb you have got ? According to MSI the 848P Neo-S only has 2 RAM slots.

Yes, it seems the motherboard identification is in error.

bshen, if the board has a dual-channel memory controller, which is the usual reason for memory slot color coding, only the two green slots will run memory in dual-channel mode. The third slot is an odd color because if it is used, the memory complement will increase, but all the memory will be operated in single channel mode, reducing the bandwidth.

A few motherboards could still run in dual channel mode this way with a specific combination of DIMMs. We would need to know the correct board model to find out if this is the case here.

you are absolutely right platypus. I got the motherboard wrong. now, im sure it s a ram slot. Does two greens and one purple slot mean anything significant? and limitations? anyone?

As I indicated, it generally means the matching slots for dual-channel operation. If you can provide the correct motherboard model we can check further.
