So far so good building my new rig, just stumbled upon something that I guess I do not understand. So far I have bought the A8N-SLI Deluxe mobo, and AMD 3500+ 90nm cpu, and a case. Been doing some research on the memory and I came up with thinking I wanted this: CORSAIR XMS 184-Pin 512MB DDR PC-3200 PRO series with activity LEDs, Model CMX512-3200XLPRO - Retail Model# CMX512-3200XLPRO Specifications: Manufacturer: CORSAIR Speed: DDR400(PC3200) Type: 184-Pin DDR DIMM Error Checking: Non-ECC Registered/Unbuffered: Unbuffered Cas Latency: 2-2-2-5 Support Voltage:2.8V Bandwidth: 3.2GB/s Organization: 64Mx64 -Bit Warranty: Lifetime After a bit of more research I found 2 things. One.. the next ram I am about to talk about scored higher in a review site and two... the Asus site says it supports the latter as two pairs of dual channel memory but it does not support the corsair one. This is the other memory: Crucial Ballistix 184-Pin 512MB DDR PC-3200 - Retail Model# BL6464Z402 Specifications: Manufacturer: Crucial Speed: DDR400(PC3200) Type: 184-Pin DDR SDRAM Error Checking: Non-ECC Registered/Unbuffered: Unbuffered Cas Latency: 2 Support Voltage: 2.8V Organization: 64M x 64 -Bit Warranty: Lifetime Now, is that really possible? That the mobo will not support a specific stick as two pairs of dual channel but it will others? The reason for my question is I am really wanting the LEDs on the first pair but... I will most likely buy another two sticks shortly after the rig is built and I don't want it switching bakc to single channel. Anyone have any expereience with this?
