[Blackcity]

Hi guys I'm having trouble starting my PC with 4 RAM sticks (32gbx4) Corsair Dominator Titanium 6000 MHz CL30 (CMP64GX5M2B6000Z30) do you have a solution in the BIOS the CPU is a 9800x3d thanks for the help

How long did you wait after boot for the Q-CODE 15 to disappear?

It may take up to 15 minutes to finish memory training. Q-CODE 15 is not an error code.

Did you read this?

Hello Blackcity

Code 15 = Memory Training and can take upwards of 15 minutes.

It's not recommended to combine memory kits.    

I'll suggest to pair up your memory with the serial numbers and use 1 memory kit in the A2-B2 slots.

I managed to start the PC with 4 sticks of RAM but I can't go beyond 4800mhz while with only two sticks I managed to get even 6200mhz stable solutions?

these are the settings of the Expo 1 4800mhz profile by changing these parameters

You won't get all 4 sticks to run at 6000MHz, it's too much for the cpu's memory controller to handle.

Stick with 1 memory kit in the A2-B2 slots.

ok perfect since it works at 48000mhz I'll leave it like this is there much difference in slowdowns?

Well, it would depend on the games you play. But generally, games prefer speed over capacity.

If you use your pc for work, capacity would matter more than speed.

16GB of memory has been the standard for quite a while. Some newer games are recommending 32GB, so one 64GB memory kit is more than enough. 

If you want to fill all 4 memory slots for aesthetics, corsair has light enhancement kits. Your memory part number shows you have the Dominator Titanium.

Here is a set of black ones. -  DOMINATOR TITANIUM DDR5 Lighting Enhancement Kit — Black

Thanks but on another PC I already use those fake RGB sticks at this point I keep the 4800mhz RAM combined with an rx 9070 xt playing in 4k I think that this speed will not cause me problems

Guys, I put two RAM sticks again yesterday, I had problems with black ops 6, continuous crashes with those settings, 2x32gb went to 6400mhz without problems, big difference compared to 4800mhz
