RAM Upgrade issue

  craigf1uk 18:59 30 May 09

I have recently upgraded the RAM on my PC so that now I have two 512MB DDR2 modules in the slots - all is working fine. However, I have a third slot for RAM on the motherboard but when I install a module into this slot I cannot boot up (there is no failures, just nothing happens). Taking the modulr out again and all is well. Any ideas how I can activate the third slot? My max memory should be enough to put in a third 512MB?

What happens if you take out one of the 2 installed modules of ram and place it in the third slot, so you are still running 2 sticks of ram but are using the first and third slots?

Also does the third memory module work if you swapped one of the installed modules for the thrid one?

Some motherboards can only support certain speeds in certain combinations in certain slots.

So - as per above - what motherboard.

Finally had a chance to try out the above, swapping one of the 512MBs into the third slot causes the boot-up issue, so I now know that I'm not overloading the motherboard.

The motherboard is a Leadtek WinFast NVidia CR18D/G
