Hi all. I bought a new system and installed them today. But when it starts there is no display. Other components (fan,gpu ) looks they are working. Please help me to solve this situation.

System:

Mother board : asus rog maximus z790 hero
gpu: asus rtx rog strix 4090 oc edition
ram: g skill trident z5 64GB (2x32 6400 mhz cl 32 ddr5 ram(F5-6400J3239G32GX2-TZ5W) (I bought 2 of them total 128 gb)
cpu: intel 13900k i9
ssd: samsung 2tb 990 pro nvme (Picked 3)
psu: corsair ax1600i 80+ titanium

Thanks for your helps from now.
 
I would pull 2 of the memory sticks out and try again. There are also 2 slots the motherboard prefers when you run just 2 sticks.

Buying 2 kits of memory with 2 sticks each is not the same as buying a kit with 4 matched sticks. Even in the part numbers are identical the memory sticks are not.

You also have other issue. The memory kit you purchased is on the list from asus but not a kit of 4 even if you purchased them. The only kit they have on the list with 4x32 is from kingston and only runs 5200.

Firstly thanks for your reply. I tried with just 2 of them. İnstalled dim a2 b2 but issue keeps on. Do i have to buy new ram?
 
It should run with 2 sticks. I would of course try both kits. You could I guess try just 1 stick of memory.
In general any ddr5 memory should post the system running the memory at the lowest speeds. The problem generally comes when you try to run them at the faster rated speeds.

It would be unlikely all the memory you have is defective. You then start to suspect things like the cpu or the motherboard. It can also be caused by the cooler applying improper pressure to the cpu chip.

These issues are really a pain to find when you do not have spare equipment to test parts in. You could remove the cooler/cpu and inspect the socket for bent pins. After that is a guess is the memory controller on the cpu bad or is it the motherboard.

What does mean if gpu fan doesnt work and no rgb light anymore on rams? I m really scared.
 
Seems you have a fancy board. What does the led number thing display.
You can look the codes up in the asus manual and it might help a bit.
The numbers should change as it boots and checks stuff and if it gets stuck the code will stay the same.
