DDR5 XMP does not work.

Any thoughts? (Z690i Unify and 6600mhz corsair vengeance)
Tried the usual voltages and nothing.

I don't know about Intel but I have seen videos showing that AMD DDR5 systems need a long time and many reboots to complete RAM training.

Just noticed system hangs even when saving fan rpm's. Have a suspicion the bios is ****.

Does all the CPUs support that speed? Is pretty hardcore. I assume only 2 sticks?

I am no expert, but I would have assumed that the XMP profile would function. Yes, two sticks, mobo only has two slots.

Now working, think the posting is broken. I'll stick it through aida tomorrow.

I had the same issue. Turns out my Asus mb wanted the sticks in 2 & 4 rather than 1 & 3. Ahh seen your mobo is 2 slots. Ignore

Done the stick stuff, board is faulty. Used another GPU and black screen hangs on anything that needs a restart, like most installations theses days.

Is the exact memory kit (the long model number) on your motheboard's QVL list? If it is, then your CPU IMC is not good enough to run this speed, try 6400Mhz

It is and XMP is working. I would change the title if I could, the problem is black screens through restarts. Nothing to do with the ram, tested in memtest and tried another brand. PC had to switch off and on to get through the windows installation, the same with the updates. The same happens if I make a setting change in bios and requires a reboot. It is the mobo or the CPU is my guess, changing ram speeds does nothing.

Update: The thread can be locked/deleted if possible. Took out CPU and put it back in and all functions as it should, someone explain that to me.

poor pin contact, or overtightened heatsink would be my guess, seen it a lot with AMD, but not so much with Intel and not with those symptoms

Probably over tightened then, the pins were fine. Oh well, case closed.
