Desperate: Tried installing additional RAM-blocks and now my computer turns on for 1second, then off and immediately on.

Hey guys

I previously had 2x4GB RAM in my computer. I've been thinking of upgrading to 2x8gb, but a friend said I should just get 2 more of the same RAM. So I did that, so I'd end up with 4x4GB of the same RAM blocks. This guy usually knows what he's talking about.

Anyway, I got the 2 new RAM, but rather than being blue like the ones I already had, they were yellow. Their serial number was the same, so I thought it was still good. Well I installed them and computer didn't boot. I then read that RAM need to be from the same DATE, not only exact same kind. Well, that sucks. So I take out my old ram, put the new RAM in the old RAM slot and check them. Still doesn't work.

So I put my old ram in my PC, same as before and put in and now my PC won't start. I've tried with both RAM separately.

I'm using an ASuS Z97-A motherboard.

When I turn on my computer it lights up for 1-ish second, then turns off before turning on again after another second. But then it just stands there. There's light in the computer and the fans are running, but nothing else is happening: No display-

Did I somehow fuck up my motherboard when trying to install these RAM?

Sincerely,
Niklas

Clear the CMOS. If the computer still won't start, try booting with just 1 stick.

What were the new and old ram models?

 

[helpstar]

be sure the RAM is locked inside the slots and use the Dimm slots A2 and B2 (from CPU the 2nd and 4th) for both.
If you wanna try only one, install it into slot DIMM_A2

Like previously suggested, clear the cmos by jumper
Clear RTC RAM (3-pin CLRTC)

RAM is guaranteed in the form it is sold.

Matching up identical part numbers and/or combining multiple kits have no guarantee to be compatible together.

Workarounds for getting extra memory to work include:
Lower memory frequency
Increase DRAM voltage
Relax DRAM timings
Lower CPU multiplier

The old memory has never been tested with the new memory so you take responsibility for doing your own compatibility testing with no guarantees.

Adding extra memory causes additional stress to be placed on the memory controller. As a result, the PC may not boot or the memory may no longer be able to operate at rated specifications.
