DFI Lanparty NF4 939 Problem

**bigbeark** · 01-16-2020, 01:38 PM

Last time I booted this board it worked but the 1st ram slot did not work.

After a couple of years storage, when I attempt to boot I get the continuous beeping sound. I can't find a manual to download, but I am assuming this has the award BIOS. A search suggests that this is the Ram failing to be recognized.

There is no sign of bulging caps or damage to the board.

Do I assume that the memory controller has died?

I have tried various tested working Ram, and always the continuous beep, no matter which slots are used.

Will test the CPU ASAP, but the fact I'm getting the beeps means that it's a ram problem.

Any experience or suggestions? Thanks in advance.

Most commonly this will be a bad contact in the RAM slot. Make sure to clean thoroughly with contact cleaner, double check you RAM sticks and the contacts are in good conditions and compatible.
Memory controller is inside CPU so you can also clean CPU socket and make sure CPU is in good conditions as well.

i've seen plenty of these boards on junkbay. the problem is that i see 99% of them come with kzg caps which are failure prone. for some reason, dfi luvs using kzg and or kzj caps on these boards which are their primary reason for failure. caps can fail without bulging and kzg/kzj fail while sitting unused and unpowered which is what u experienced.

also check your power supply. a failing psu can also exacerbate issues with failing caps on the board.

Concur with the two posts above me.

Tried re-seating all hardware first (CPU, RAM, etc.) several times, as that tends to "clean" the contacts good enough most of the time. If issue persists, indeed check for bad caps as Chaos suggested above - especially if you have United Chemicon KZG or KZJ, as they do indeed can go bad when sitting on the shelf (and in general, they are just not good and can fail with use too.)

Yes, this board is loaded with KZG and KZJ. I will remove and replace them and report back. Thanks for the heads up.
