Question about Abit KN8 Ultra Motherboard
I have 2 pcs DDR that located in DIMM 1 and DIMM 2, with the same manufacture. Each of DDR are:
DIMM 1 -> KINGSTON, DDR PC3200, CL3, 512 MB
DIMM 2 -> KINGSTON, DDR PC3200, CL3, 1024 MB
But the problem is The Dual Channel still not active. I see on first boot was "1ST SINGLE CHANNEL 64 bit". Then I try to find the new BIOS version, but it didn't available on www.abit.com.tw.
Could you help me my friends ... ??
The problem might be your ram are not dual channel. Dual channel ram are usually matched in pairs in speed and size of modules ( 2 modules of 1gigs or 2modules of 512). Check out crucial technology site in the support section either F&Q or live chat with them....Doc

You can install 128 MB, 256 MB, 512 MB, and 1GB DDR SDRAM DIMMs into the DIMM sockets using the memory configurations in this section.
• Install only identical (the same type and size) DDR DIMM pairs
using the recommended configurations.
• Make sure that the memory frequency matches the CPU FSB
(Front Side Bus). Refer to the Memory frequency/CPU FSB
synchronization table on the next page.
• This motherboard does not support double-sided 16-bit DDR DIMMs.
• Do not create a three-DIMM configuration in dual-channel mode. The
third DIMM is ignored in the dual-channel operation.
