Greetings all..

I have a question about an Asus A8V-E Deluxe (BIOS Rev. 1012) motherboard. I currently have an AMD Athlon 64 3700+ (San Diego Core) and 2x512 MB of Hynix (HY5DU56822DT-D43) PC-3200 DDR (400 MHz) memory. This is listed in the QVL as follows:

512MB Hynix HYMD264646D8J-D43 3 Hynix DS HY5DU56822DT-D43 V V X

The two "V"s at the end represent the DIMM socket support. So, my RAM is listed as supporting A (one module inserted in any slot as Single-channel) and B (one pair of modules inserted into either the blue slots or the black slots as one pair of Dual-channel). Option C (4 modules inserted into both the blue and black slots as two pairs of Dual-channel) is not supported.

Currently, I have my RAM sitting in DIMM_A1 and DIMM_B1, which gives me one pair of Dual-channel and works with no problems.

My issue is that I want to upgrade to 2GB of RAM and don't want to lose the Dual-channel. Assuming I am reading the QVL correctly, it would appear that if I purchase two more identical sticks of RAM, then I will have 2 GB but will only have Single-channel. Is this correct? If this is the case, how much of a performance hit can I expect to take?

On the QVL, there are two Samsung sticks that do support 4x512 MB. If I bought just 2x512 MB of Samsung and combined it with my 2x512 MB of Hynix, would I have two pairs of Dual-channel or would it kick it down to Single-channel?

The only other option I could see is replacing my current memory and using 2x1 GB of some other brand. On the QVL, I don't see any 1 GB sticks functioning as Dual-channel. Can you have 1GB Dual-Channel?

Sorry for such a long post but I really want to understand what I'm looking at here. To summarize, my main goal is to have 2 GB of RAM running in Dual-channel at the rated 400 MHz spec. I'd really appreciate any advice that you all could provide.

Thank you!
