One long beep - 2 short beeps - repeat

[Mustii34]

Hello everyone,

I've got a weird error with my PC. I bought all the parts new and assembled it myself and yes, I have built many computers before. I'm getting a really weird issue though with the 4th DIMM slot. I can get the computer to start perfectly with RAM sticks on DIMM 1, 2 and even 3 but as soon as something goes into the 4th DIMM slot, I get one long beep, 2 short beeps then a repeat. I've confirmed it's my RAM causing the error. Before I go out and buy new sticks of RAM, is there any way I can fix this error?

Specs:
i7 6600
DDR4 2133MHz G.skill ripjaws (4gb x 4)
Asus h170M-plus
GX750W PSU

First try booting with just 1 stick of RAM in the 4th slot, leave DIMM 1 2 3 empty and put just a single ram in DIMM 4. Try it with every stick (you have 4 sticks, try with each individually) and report again.

had an issue with my pc when i built with the RAM that i connected it to the slots, it would run with 2 wouldn't run with 4 . Changed motherboard and had the same issue. A Bios update solved it. Must be something wrong with the voltage or timing? try a BIOS update.

Tried that, that's how I got the one long beep followed by 2 short beeps. Filling all DIMM however leaves me with no BIOS beep and no POST.

I also thought this would be the issue.. It wasn't. I updated to the latest version today and that's the only reason I started getting the beeps through BIOS. Before the computer would just stay on and not provide any beeps what-so-ever.

Seems like you will have to RMA the motherboard for a dead DMI slot.

Wish I could. Problem is it was working before. Then randomly stopped, and for all I know it'd start working again in future. Do you think I'd need to take it back? Nothing wrong with the RAM right?

If ram works everywhere else, just not in the 4th DIMM, then it's not the ram. And anyways while you wait, might as well RMA the ram, not just the mobo.

Went ahead to do further testing, tried each RAM in each DIMM slot, all worked everywhere including DIMM 4 except one stick of RAM which didn't work anywhere. I've labelled it with clear. removable tape. Now to test If I can get 2 RAM running at the same time.

Thoughts on having only 3 sticks in there rather than 4?

UPDATE:

3 RAM is running. DIMM 1, 3, 4 is working fine. Turns out it was the one bad stick of RAM haha

Well then, yeah you have done the correct test, RMA the ram.

Sorry to keep this thread going.. but what just happened.
It turned off and refuses to turn on at all now. Motherboard is getting power (Green light shown on mobo) but none of the switches are triggering anything?
Ugh. This is such a pain.

Try a different power outlet to begin with.
