Question about EPoX EP-9NPA+ SLi Motherboard
Why cant I run in dual channel mode with amd 4400+ x2 ? The RAM ran in dual ch. mode with 3800+ x2, why not with the 4400+ ?

You can update your chipst nVIDIA nForce4 SLi.
This is not a easy task. It requires you to download the proper drivers. nForce will do this for you by checking your current system. Click this link to nForce:
Do not update your system by doing an install. You will have to remove the current nForce devices manually through device manager. (DO NOT restart your PC untill you have replaced the nForce drivers with updated nForce software).
If you do, you'll find your going to have to do a complete reinstall of windows & you will loose your current data.
Updating your ssocket 939 will run better. Your dual channel should post after update. It was a waste searching EPoX for faq's. Couldn't even download their/your manual. Please read recommended files to help with the update, these are worth every minute. (I learned the hard way).
Good Luck & Kind Regards.
& please vote.

Tips for a great answer:
For dual-channel memory configuration (2), you may:
• install identical DIMMs in all four sockets OR
• install an identical DIMM pair in DIMM_A1 and DIMM_B1 (yellow
sockets) and another identical DIMM pair in DIMM_A2 and
DIMM_B2 (black sockets)
* Always use identical DDR2 DIMM pairs for dual-channel model. For
optimum compatibility, we recommend that you obtain memory modules
from the same vendor.

Dual-channel architecture requires a dual-channel-capable motherboard and two or more DDR, DDR2 SDRAM, or DDR3 SDRAM memory modules. The memory modules are installed into matching banks, which are usually color coded on the motherboard. These separate channels allow each memory module access to the memory controller, increasing throughput bandwidth. It is not required that identical modules be used, but this is often recommended for best dual-channel operation. It is possible to use a single-sided module of 512 MB and a double-sided module of 512 MB in dual-channel configuration, but how fast and stable it is depends on the memory controller.
If the motherboard has two pairs of differently colored DIMM sockets (the colors indicate which bank they belong to, bank 0 or bank 1), then one can place a matched pair of memory modules in bank 0, but a different-capacity pair of modules in bank 1, as long as they are of the same speed. Using this scheme, a pair of 1 GB memory modules in bank 0 and a pair of matched 512 MB modules in bank 1 would be acceptable for dual-channel operation.
Modules rated at different speeds can be run in dual-channel mode, although the motherboard will then run all memory modules at the speed of the slowest module. Some motherboards, however, have compatibility issues with certain brands or models of memory when attempting to use them in dual-channel mode. For this reason, it is generally advised to use identical pairs of memory modules, which is why most memory manufacturers now sell "kits" of matched-pair DIMMs. Several motherboard manufacturers only support configurations where a "matched pair" of modules are used. A matching pair needs to match in.
