i5-6500 build, 5 beeps and reboot

I've read a few problems like mine here and I wanted to add to the pot.


  • -i5-6500 skylake
    -Tried on two seperate gigabyte LGA1511 mobos inside and outside of the case on cardboard in a complete anti-static environment (I'm a technician.)
    -Two seperate PSUs, both tested on another build as working, 750w
    -Cooler master Evo sink and fan, although I tried stock just in case.

Just as the title states, I was hit with five beeps then the computer would restart. Both the 8-pin and power supply connector are firmly seated for each motherboard. The boards power on, cycle through, and shut off after 5 beeps. Absolutely no bent pins in either socket and each socket has tested good. I've used two NEW instances of the i5-6500 skylake and have gotten the same 5 beep cpu error code before it shuts off. This is getting really expensive and my patience with it is starting to wear.

How possible is a double DOA for motherboards or CPUs? Has anyone heard of an issue with the skylakes?
 
Solution
Okay the only thing i could think of is that you have your stick of ram in the wrong slot. Move it to the second slot that is closest to the CPU. See if that works.


Yeah, that's what prompted me to return the first one, but now the new on is doing the same thing. Just seems oddly lucky to get two DOAs.
 


Well you would need a new CPU, not a new mobo.
 




Sorry, had to clarify. I have both a new CPU and Motherboard after the first CPU failure.
 


Sure can, with cpu and cooler on? All cables connected or bare? I appreciate your time.
 


Oh okay, well damn. So what exactly happens when you try and boot? you just get the beeps and a black screen?

This is what happens every time on both motherboards with both cpus
 


Shit, didn't mean to hit the best answer button. I'm on my phone. Can you view the video I posted?

I've just seen that the ram I have is 2400 vs the 2133 that is allowed by the board. You don't think I've shorted out both my processors do you?
 


Hmmm... Well Gigabytes website says 5 short beeps is a CPU error. But... those sounded like long beeps to me. So I would probably just try and get a new CPU, and if it does it again i would call Gigabyte. Or call them first.
 


Sounds like the option to go with. Good thing I lucked out on amazon for the cpu's or these returns would be annoying.

I'm also gonna try it with different ram. The site said 2400mhz would be fine, but specs define it as 2133 only. Maybe the micro atx is finicky and doesn't post without a cpu error if the ram isn't installed.

 
alright, I do have an update. I broke down and called gigabyte after my 3rd, count it, 3rd cpu gave an apparent error. The 5 beeps are not short beeps and do not indicate a CPU error. Most likely it has to do with some sort of ram error. The support dude said it may very well be the motherboard, which is weird that I just happened to get two separate motherboards DOA.
 


So it turned out to be a ram frequency issue. On the new gigabyte micro atx's, you cannot breadboard without RAM. It will give you a cpu error because the initial post check inputs small amounts of data using your ram which then addresses it to your speaker/led/interface. Also, can't just rely on throttling your ram if it's a higher frequency. In my case, I had used 2400mhz initially, but switched to 2133mhz when all else failed. That allowed a successful boot, memory reference, and then post in my case.

I think it kinda sucks that the beep codes mislead me for so long, but I'm just glad this tiny build is up and running. Time for software!
 


Thats crazy. Glad you figured it out tho!
