Dual Channel Memory

[ror_b211]

For a while now I've had 1GB of RAM but with an unorthodox configuration, which is 2x 256mb Kingston HyperX PC4000 (sold as a 2x256mb kit) and 512mb stick of some cheapo RAM. It works at 200mhz & 2.5-3-3-6 and obviously not in dual channel mode.

The reason it is like this is because when I first built the computer, I saved money in several areas, including the RAM, so I could afford the CPU (I was on quite a tight budget for a gaming PC). So I had 512mb of the cheapest RAM I could find. I decided to upgrade this after a while to 512mb of Kingston RAM which worked at 250mhz, dual channel...etc (ie. Better). So I had the old 512mb stick lying around. So after a while I decided to put the 512mb stick back in to get 1GB.

Anyway, I decided to upgrade again, but I need to know if this config will work in dual channel:

Channel 1:
Slot #1: 256mb Kingston HyperX PC4000
Slot #2: 256mb Kingston HyperX PC4000

Channel 2:
Slot #3: 256mb PQI PC4000 DDR TurboMemory
Slot #4: 256mb PQI PC4000 DDR TurboMemory

The PQI memory is sold as a dual channel kit:

Thanks for reading all that!

Any help appreciated, thanks.

Check your manual. I downloaded one to double check and your DC memory configuration is the same as my Asus board. Slots 1 & 3 need to match as do Slots 2 & 4. PQI isn't listed on their accepted vendor list for memory but that simply means it hasn't been tested.

Ok so does that mean that I should put the Kingston Slots 1 & 3 and PQI in 2 & 4?

yes

I was pondering between getting an extra 1GB stick of RAM to make 2GB (making an even odder setup) or getting the PQI and upgrading to 1GB of PC4000. Anyway I think i'll go with the PQI.

Thanks for the help!!
