After upgrade ram, iMac start 3 beeps

Hi Guys, i have try to upgrade my ram from 8G to 32G with new slots of memory.

It went all well. I have been setup the RAM, and it's was working very well.

I put my PC on sleep, then i wake up with strange beep sounds. I had to shutdown. I try to start it again, only blank screen with 3 beeps again.

I try different combinations for slots positions ( 2 first slots works well ) if i put memory on 3 or 4 slot, it's getting the beep, no matter what.

Please let me know for your solution.

I try to replace memories, and i got also new one from G Skill.

I use to start with 8G of each. It's not working. Three beeps are doing again.

- I test it out with 4G of each slot, and it's start working (Crucial brand) (max 16G at all)

Can anyone suggest me if i have software or hardware problem? Why i am not able to start my computer with 32G or 24G?

Did something like this happend before?

it is either something with the Ram modules or the seating of the Ram is not good enough.

3 beeps: Ram problem, nothing else. Reread this thread.

Well i think you should Reread my thread.

- This is my new set of 4X8G ram slots. It's just not possible they to be not "good enough" or seating to be bad.

I have been even try combination like

1 - 8G

2 - 8G

3 - 4G (not working) original

4 - 4G (not working) original

Event mixing

1 - 4G original

2 - 4G original

3 - 8G (not working)

4 - 8G (not working)

I have been even trying with

1 - 8G

2 - 8G

3 - 8G (not working)

4 - 8G (not working)

Only first two slots does not make trouble. Once when i add third or four with 4+ it's making trouble.

Notice: All slots working with 4G

Anyone some solution how i can debug this instead of three beeps on start?

That means that you should return the Ram and ask new ones.... as we have said already.

I return the RAM, i got new one as we said already before. I am speaking that with NEW one (that i got yesterday) it's happening the same.

Is there any way how i can boot to start instead of 3 beep?

If you are sure it is the correct specification, do it again, as I have said. You can not solve this yourself...
