Specs: Microsoft Windows Vista Home Premium, 2.3 GHz / 1917 MB
I am wanting to upgrade the memory in my HP S6142n pc. It came with 2 GB and I wish to upgrade to 4 GB (running Vista Home Premium).The motherboard is an ECS MCP61PM-HM.The chipset is Athlon 64 x 2  4400+ Duel CoreI have a few questions:Should I just add 2 GB to my existing memory (Samsung PC2-5300, 333Mhz) or take it out and put in a new set of 4 GB  that matches (and go up to 6400)?Is there one manufacturer that is more reliable than others (I know this is subjective)? I have read good things on G SkillThe reason for doing this (other than picking up some speed) is that IE is extremely unstable with my current system. Multiple times per days I get the white screen and message that it has stopped working. This is with only a few windows open and maybe Outlook. Also with very little running, I have 2 GB of RAM installed but only 546 available physical memory. Hopefully this will help these things. I anyone has any other advice it would be helpful too (graphics card, to much Vista and HP crap bogging things down, etc... Also the memory timing is set to 5-5-5-15 at 1.8 volt.Thanks very much

PC2-5300 is the wrong RAM...I don't know why HP does that. The correct RAM for an AMD A64 system is PC2-6400 (DDR2-800).

Here's 4GB (2 x 2GB) of Corsair DDR2-800 for $25 after rebate:

In answer to what RAM to buy. Your HP probably doesn't have any options to adjust RAM voltage so you may want to buy RAM that is set to run at 1.8V. Some performance RAM may require a higher voltage and your board may not be able to supply it.

If you want to you should be able to see if you have any way to control RAM voltage. If so, then the above is not applicable.

The RAM that jam linked to is an example of what I described. The specs on that RAM calls for 1.9V. OK if you can supply it.
