Increase RAM

By nicksman ·
I have a MS 6351 Ver:1 motherboard (not accounted for at MSI.com!) with two DIMM slots. I had 2 256 memory cards amounting 512 Mb RAM. I bought recently two 512 DDR2 DIMM cards to put in the same slots in order to increase memory to 1GB. However I still get 512 Mb RAM reading. I wonder if this is a motherboard limitation to less than 1 GB RAM or that I can increase the RAM capacity by altering some BIOS readings?
Thank You

You don't give us much to work with here

But try fitting just 1 stick of RAM and see how BIOS Reads it.

If you have a Pentium 2 or 3 M'Board here with SD RAM it will be the BIOS is limited to a certain size of RAM and Can Not Map Ram bigger than this size per RAM Slot and sometimes you can not populate all of the RAM Slots with the Biggest RAM Sticks.

It is also possible that if you fitted High Density RAM it is unreadable as the M'Board can not support High Density RAM.

High Density RAM only has Chips on one side of the RAM Stick as a general way to identify it. Depending on what type of CPU you have here you are limited to what the M'Board can use the newer the CPU Type the More RAM it can carry but typically P2 or Equivalent CPU's can use up to 256 MEG. P3 or equivalent under 1 GIG Speeds use the same capacity RAM and the CPU's over 1 GIG can use larger RAM Sticks sometimes but this is limited to 512 MEG Capacity.

When you get to the P4 or equivalent CPU Types these M'Boards can generally support up to 1 GIG RAM Sticks of the DDR Type.

Low End System

by TheChas In reply to Increase RAM

Looks like the MS-6351 board was part of a low end system.

Considering that this is a Pentium III system, I would say it's time for a major upgrade.

MS motherboard Limitation

by nicksman In reply to Low End System

I feel obliged to thank you all for your prompt replies which were very helpfull. They confirmed my worst guess that the MS 6351 motherboard has a limit of 512 RAM but I was unable to find out. Thanks again.
