Hi ! I'm a greenhorn in need of advice .. Have an Athlon 64 3400+ 2.4Ghz with Asus K8S-LA which I understand is capable of supporting 2GB of PC3200 DDR SDRAM in two slots. It currently has only one 512MB DIMM installed, and I'd like to remove that and max out with 2 x 1GB. I am under the impression, perhaps incorrectly, that DDR (dual data rate) is not the same as Dual Channel, and dual channel modules can not be used, and/or not supported in an Athlon 64. I've searched and read for hours and days and can't find an authoritative answer to the dilemma. Some dealers advertise PC3200 DDR , but the fine print always says they are designed for Dual Channel. The manufacturer sites aren't any help either, as their wordings are often misleading. Can Dual Channel modules be used safely without crashing the system ? If not, can someone direct me to a manufacturer that suppies modules for this rig without the dual chanel hype ? With tongue-in-cheek I ask: Will someone please explain or tell me where to go ? THanks in advance for your help.
