I have a ECS P4M800PRO-M, it has a SIS chipset which allows either DDR or DDR2 and S775. As the name implies, its limited to 800MHz FSB. Also it has a memory limit of 2GB of either flavor, I've used both DDR and DDR2 on it equally well, but never together.Originally posted by: DrLynx
Hello all,
I have a Athlon 64 3500+ processor with a Asus A8N-E motherboard. I have 4 GB of DDR 400 or PC3200 or 400 Mhz DDR RAM.
My motherboard conked off last week. Seems like 939 boards are totally out of the market (our local market atleast - India). I can either go for a Asus A8Vxx board that had been sitting in the dust for over two years or I can buy a Intel Quad Q6600 and a good motherboard.
But, the problem is that, everything seems to be supporting DDR2. I do not know if mine is DDR2 or DDR1. How do I find this out?
Plus, they are all supporting 800 Mhz. Mine is just 400 Mhz. Will this memory work? I really do not wish to throw off 4 GB of RAM. If it will work, will it slow down the board's bus speed thus bringing all speed down giving me no advantage of the upgrade? I have heard that in Intel boards, the two bus speeds are separate but I just want to confirm.
Thanks in advance.
