Question about DFI LanParty KT400A Motherboard

2 Answers

Lanparty kt400a I have had my motherboard for 5 years now using Amd athlon AXDA2500KV4D, 1.5 gig of DDR PC3200 ram, 120gig WD Hard drive, NVG34AL DVI 128MB video card. I use it for gaming online and had no problems till now. What it does is it shuts off hard drive, cd/dvd drive but the fans and lights still remain. This problem happens when i am in bios or before windows xp is starting. I checked my hard drive on another computer and is good. I checked the cpu temp setting in bios before it shuts down and check was good. I also checked the psu on another computer and runs good. I thought that it could 1 of the memory sticks so i tried them on another computer and checks good. My setting are the same as it was for 5 years on the motherboard and bios and it down to 2 things the mother board or cpu but at this point i don't know of any way to check and see which one. Another example i should tell it that now when i try to turn on my computer the lights and fan run but nothing is loading or beeping just sits there.

    I used the cheap dfi ad77 to test my cpu and turned out good and I actually talk to dfi tech support and they said they would repair the board for $30 which is a good price. Socket A motherboards aren't being made anymore so if you would upgrade go for AM2 or AM2+.

Chip up grade options!

is a socket 754 motherboard. It will support AMD Athlon processors up to Athlon64 3400+. It is a bit long in the tooth by today's standards, and only uses DDR memory, not DDR2. You may get more of a bang for your buck by buying a "barebones" system, which can consist of a motherboard with processor and memory, depending on how much you want in the barebones package.

Typically you use the case, power supply you already have with the new motherboard and processor and ram (memory).

At any rate, if you only want to upgrade your processor, keep in mind that your board only supports up to the Athlon64 3400+. It will support up to DDR 400 ram. You would probably benefit more by buying 2 sticks of 400 DDR ram at 2 gigs each, if you don't have much ram now. If your processor is close to the 3400+, then another processor in that board isn't going to change things much.

Good luck, and write back if you'd like more help.

I want to add more ram in my pc km400/km266

Oddly enough this board has the following specs: The board supports both Althon and Duron processors up to Athlon XP 2800+ (3000+ with a BIOS update). It can handle 3 GB of DDR333 RAM (or 2 GB of DDR400, but not all types are supported). 
That's the older 184pin DDR ram in PC2700 or PC3200 guises. I can see no reason why it would only accept 2gb of the faster Ram.
Why not go over to  and run the online scan to get the true story on your board?
