PC not posting (no display Output)

[Hippmensch]

I have bought a new Motherboard, RAM and a CPU

 

Motherboard: Gigabyte Z690 UD AX

RAM: Kingston FURY Beast 2x8 GB, DDR5-5600, CL40-40-40

CPU: i5-12400F

 

From my old Pc I used the PSU, GPU and the storage (2 SSDs, 2 HDDs)

PSU: BeQuiet! Pure Power 500 W

GPU: Palit RTX 2070

 

I have put everything together but it didn't post.

The Fans started spinning and the CPU and GPU got warm.

The diagnostic LEDs for the CPU and RAM were blinking. (The user manual says if one of the light is on there is a problem with the corresponding part)

 

I tried: 

• reseating the RAM
• trying other RAM slots
• reseating the CPU
• plugging the power cables of the CPU out an putting them back in
• flashing differnet BIOS versions on the board
• Powering the system on without Ram (the diagnostic LEDs for CPU and RAM were blinking, but faster than with RAM sticks)
• clearing CMOS by removing the battery

After a few times blinking the pc tries to restart.

Please comment if you know some more troubleshooting steps or there is missing information.

Thank you in advance for your answers.

ddr5 .. check compability for CPU mainboard and ram..  that cpu supports 4800mhz ram.. not sure it helps to buy faster then. and there are heaps problems overclocking ddr5 still.

500w ? .. tried stronger psu yet?  if i use my old psu it'll be a 1600w one...  doesn't say how old your old psu are, but not that old if you reuse gpu and it's a 2070. if it's same age tho. 

 

leave the battery out 10+ minutes before putting it in again.  or if you reset with shorting the clr-cmos pins if you have them hold it for 10ish seconds.. powered OFF unplugged.

Thank you for your reply.

 

• DDR5: I looked up the compatubility on gigabyte's website (https://www.gigabyte.com/Motherboard/Z690-UD-AX-rev-1x/support#support-memsup) and the DRAM kit I bought seems to be the only one from Kingston not listed there. 
• PSU: I have no other PSU available but it powered an i5 9600k with OC before so I don't think power is the problem
• I've tried leaving the battery out for a while and plugged it back in but it didn't help.

 

Another Question: 

Do I need to connect both connectors to the psu? Or just the 2x4. I heard you could leave one unplugged if the CPU isn't that power hungry.

try to return the ram and get something that is listed.. even tho it's slower it's better with stabile system than not running at all.. or atleast if you know someone that has slower ddr5 sticks if that are better.  

honestly... i don't understand why you went with ddr5 at all.. had you gone with same board just ddr4 version you could have used the old sticks. since ddr5 still is too expencive. but that's up to you. But i will be assuming you will try to upgrade CPU PSU and GPU at a later stage, then it's understandable. 

 

thinking about it.. before you return anything:  you could try to start with 1 stick in different slots. could be a channel issue. 

 

for the powerconnector. if the cpu don't use much anyway, you should be able to start it with 1 4 pin connector in the 8 pin too..  most of those cpu 8 pin are usually just 2 4 pins together. and some weaker psu's has only one.. in some Dell/HP systems they have only 1 4 pin..

Thank you for your help.

 

I bought a new motherboard which lists the RAM on the support website and it worked first try.

 

Maybe the motherboard was dead, maybe there was a compatibility problem with the RAM.
