Question about DDR Dual Channel

[ragingazn628]

Right now I have 1 gig of kingston PC3200 Ram running at 512MB x 2 Dual Channel. My question is that if I want to upgrade and get more ram is it possible for me to continue to dual channel the 512x2 alongside with 1gigx2 totally 3gigs of ram working at the same speed PC3200

if yes then is it possible for the 1gigx2 ram to be at different speed say PC4000?

1) You can run two 512’s and two 1gig’s giving you 3gig total and keep dual channel.

2) I would get the exact same ram if possible, same brand, same speed…

ORRR... with the price of Ram now I would even just replace it all and buy the fastest ram your machine will take.

What motherboard and OS are you presently running?

Yes, I would think that if you were to add 1GBx2 + 512x2 for 3GB that it would work. I would reccomend that the RAM be the same speed (PC3200), and that you install the them in pairs, and in the correct DIMM sockets. I.e. slots 1+3 and slots 2+4. Also stick with kingston, a technician would tell you that its best to stay with the same brand of RAM.

so yes to the first question.
no to the second question, I would stay with the same speed of RAM. (PC3200).

One other thing you can do to be absolutely sure is to check you motherboard manual to find out what RAM is supported. Your looking at DDR RAM. (400Mhz).

Hope this helps.

I just looked at the price of Ram. and for the old stuff its not soo cheap.

I´m just having a problem adding 2x1Gb to my 2x512Mb, I already try all the combinations, and I can´t get Bios or Win XP see all the memory. I put it in dual channel, single channel and it seems there is no way to fix my problem.

I have a MB RS480M2-IL with AMD Athlon 3200+, all my memorys are Kingston PC3200 B400.

I can get the system start with the 4 sticks, but only CPU-Z could see my 3 Gb, but the system has some instability.

Is there a solution?

PD.- Sorry by my english (it isn´t my native language)

More sticks you have, the more issues you will have.

Rule of thumb - least amount of sticks posible, most matched/matching as posible

as for 3gb - 32bit windows will not see more then 4gb total, including video memory and other reserved memory, hence why you may be seeing less ram then installed, but it could be something else too.

DDR Ram is becoming rare and is increasing in price too.
Shop for deals and you might get lucky.
Right now the DDR2 rig is the way to go.

Look in the BIOS, there should be either a memory configuration or chipset configuration that will have settings for your memory. Look there to see if dual channel is enabled, and look for a Command Rate setting, you will probably have to set this to 2T to run stable with 4 sticks. After you can boot into windows, grab CPU-Z and it will tell you what your memory is currently running.
