So I'm having strange issues with ram posting. This is a friends build so sorry for my lack of complete knowledge of it.

Asrock 970 Extreme 3 motherboard.
Generic Mushkin? DDR3 1333 ram 2x 4GB sticks
Geforce 660 Ti graphic card
Seasonic 650W power supply
AMD Phenom II 965


Now when I turn the computer on without RAM installed it does the standard 3 long beeps. I put the RAM in it does no beeps. The computer starts up and everything seems to be running optimally. Which leads me to believe it isn't the PSU or the CPU. I've tried both sticks in the slots and every time I stick them in I lost the no RAM beep. But then I don't get the no GPU beep that should I should be getting.

This leads me to believe the RAM is bad. Problem is it's both sticks and they were working fine about a week ago. I don't want to go out on a limb and tell my friend to buy more RAM because I'm not sure it's the problem.

I've switched out the motherboard with same everything else and had the exact same problem where the ram would beep when it wasn't in. I'd put the RAM in and it wouldn't beep. But sometimes on the other motherboard I would get no beep at all even if the RAM wasn't in there.

I'm at a complete loss as to what the problem could be at this point. Don't want to tell him to buy something when I can't be sure what the problem is. Could the PSU be bad? Could the CPU be bad and only posting at certain times? Just need some advice from people who are more knowledgeable at this than me.

It's not supose to beep loads or anything when the ram is in the slots, If anything you should here 1 beep to tell you post has passed without problems.

Now some motherboards might act different but for me there has only ever been the post beep inless there was a problem.

Does the pc work fine, Does bios see all the ram, Does windows show all the ram? If everything is working then don't worry.

Neither motherboard has an onboard video. So it has a post beep if you don't have one installed. Both boards do roughly the same post beeps if the ram is not installed. Then don't post beep if the RAM is installed. Leads me to believe it's the RAM. I'm just having a hard time believing that both RAM sticks died at roughly the same time in the past week. The only thing I've changed is the motherboards so Im assuming both of them are working. Was the exact same PSU, CPU, and RAM from each swap. Just can't be sure if it's not a PSU or CPU problem instead.

Hmm its an odd one, If you can get into bios while ram is installed you could try to manualy set voltage and timings to see if that helps. I know my old mobo was very fussy with ram and caused me nothing but trouble but i got around the problem by using one stick and then setting bios up then add the second stick and it all worked fine.

Yeah my main problem is I can't get anywhere near BIOS at the moment. Neither motherboard will get to video.

We had video and everything before this, but his hard drive turned out to be bad. We installed a new hard drive and then we can never get any sort of video and the RAM doesn't want to pick up. Just blows my mind to think that both those RAM sticks went bad in that time.

Sounds like similar problems I was having with an i3 build.

When you boot with the RAM installed, do all the fans spin up including the GPUs?
The issue sounds to be the power supply, if you can get your hands on a spare then give that a try.

All the fans turn on and the post beeps happen as soon as it's turned on. Unless of course the RAM is installed. Tried this on an Asrock 970 Extreme 3 and ASUS M5A97 LE R2.0 and they get the exact same problem with the beep with no ram and no beep with ram. It's easy to assume it is the RAM at that point but I used all the same parts for everything else so I can't exactly be sure.

Hi

Just so others from the TPU community can reference the codes

Beep Codes.jpg

-double check to see that there are no grounding issues with the case and mobo or other

-reseat the CPU [just for good measure]

-Clear CMOS [remove battery and unplug power to motherboard] let the board stand for a while

-reinstall the battery and reconnect power to mobo

-ensure the RAM is installed to DDR3_A2 & DDR3_B2 [and or boot with one stick in DDR3_A for trouble shooting]

example:
Dual Channel.jpg

-try booting to bios screen with minimum hardware attached only [PSU, motherboard, CPU & Cooler,one stick of RAM and vga card] *attach monitor to vga card

So I've found out that those RAM sticks work in another computer. That leaves the PSU or CPU that can pretty much be the only problems. I don't feel the CPU is bad because I get the RAM beeps and have never got a CPU beep on either motherboard. Could the PSU just not be supplying enough power?

Hi

never got a CPU beep on either motherboard
Is no beeps a bad CPU! ?

BeepCodes.jpg

-reseat the CPU [just for good measure]
- test the CPU in another PC system

- unplug PSU connections from motherboard and double check they are secure

- check PSU with Power Supply Tester
