Hello everyone, computer was brand new. Working perfectly. Decided to finish out my upgrade with a bump from 2x16 to 2x32. System would not post, RAM light stayed on.

-Tried each slot individually with 16gb stick.

-Flashed 3 times

-Shorted the RTC pins a few times.

Specs:

13900KS, Z790 ProArt Creator, 4090, 1000W, 2 TB NVME

Original ram that came with system: DDR5-6000 CL30-38-38-96 1.35v (FS-6000J3038F16GX2-TZ5NR)

Upgrade: DDR5-6400 CL32-39-39-102 1.4v (FS-6400J3239G32X2-TZ5RK)

Any and all advice is greatly appreciated.

A good 1st step is to reset the BIOS and leave XMP off. Will it boot under those conditions?

Z690 Hero, BIOS 3101, MEI 2345.5.3.0, ME Firmware 16.1.30.2330, 7000X Case, RM1000x PSU, i9 12900K, ASUS TUF OC 3090TI, 2 x 16GB Corsair RAM @ 5200MHz, Windows 11 Pro 23H2, Corsair H150i Elite AIO, 4x Corsair RGB fans, 3x M.2 NVME drives, 2x SATA SSDs, 2x SATA HDs.

Negative.

What happens if you put the old RAM back in?

Same issue. No post. RGB is on, fans are running normally. DRAM light is on.

OK, so my only other idea is that your cooler might have been overtightened - that can affect RAM and maybe swapping the sticks around has disturbed the CPU mounting. You could try slackening off the cooler and then retighten, but not too much. Also make sure that the cooler mounting posts haven't damaged any traces on the motherboard. It can happen with large posts and if overtightened without protective washers.  If you remove the cooler, also check under the CPU for dirt or damaged pins in the socket. 

I would also double check all connections to the motherboard, PSU and GPU. Something might have been knocked or disturbed. Otherwise, think I'm out of ideas.

I appreciate you giving it a shot.

I can't find the new memory kit on the QVL at Asus or the memory finder at GSkill. FS-6400J3239G32X2-TZ5RK or F5.... I just don't see that listed as supported. But that doesn't explain why the old memory doesn't work when it did before. I looked at the memory config at GSkill and only found AMD systems supported by the original kit.   ?? Not sure. Maybe test another kit?? Check the QVL.

Ha, it is F5 not FS. ****** these eyes.

Know the feeling. I would check that QVL closely. Is this a PC you built yourself? I don't think it's the right memory. Why it worked before I don't know.
