What DDR5 kits are actually hitting 7200MHz+ stable on ASUS Z790 boards right now? Honestly I've been building rigs since the DDR2 days and I've never had this much trouble with simple XMP profiles but this setup is driving me crazy.
I'm trying to finish a 14900k build for a client here in Philly by Friday and the G.Skill 8000 kit I bought just wont cooperate on my Z790-E... it keeps throwing errors in memtest if I go anywhere near the rated speed. I've messed with the VDD/VDDQ and even tried loosening the timings but nothing works. Is there a specific brand or die that actually plays nice with ASUS or am I just chasing ghosts at these speeds? I've got a $400 budget for the RAM swap if I have to return these sticks...

I once fought a Z790 for days before realizing 7200 was basically the limit for those 4-slot boards.
- TeamGroup T-Force Delta 7200MHz CL34: fast tho.
- Kingston FURY Renegade 6400MHz CL32: safer bet. Just go for stability.

I'm happy with 7200 because it works well and saves money.
- Corsair Vengeance RGB DDR5 7200MHz 32GB CL34 XMP II is stable. No complaints tho.

TL;DR: High-speed DDR5 marketing is basically a scam and trying to hit 8000 on a 4-dimm board like the Z790-E is just asking for a headache. Honestly its ridiculous how these companies act lately! Selling these extreme kits when they know they only work on a tiny handful of 2-slot boards is such a joke. Ive been building since the early days too and the way they market this stuff now is just garbage tbh. We are paying premium prices just to be unpaid beta testers and it drives me crazy... I spent way too many hours on my last build just fighting with sub-timings that should have been stable out of the box. Definitely check out the Actually Hardcore Overclocking channel on YouTube if you want to see the technical side of why this is such a nightmare. Its amazing how much they charge for stuff that barely works half the time!

Oh man, I love this thread so much!! This reminds me exactly of when my buddy Dave went through a massive brand war with himself last summer trying to fix his workstation...
- He was comparing these two giant brands and swearing that one had better stickers so it must be faster
- I just remember laughing so hard when we realized he had been trying to force them in backwards for like ten minutes cause he was so tired
- He spent way too much on those flashy kits when the basic ones were probably fine but he just loved the look
- The whole thing turned into this huge debate about which company had better customer service hold music while we waited for a technician!
- It was such a fantastic disaster to watch from the sidelines tbh. Building rigs is seriously the best hobby even when nothing works right lol. Just total chaos!

> the G.Skill 8000 kit I bought just wont cooperate on my Z790-E Man, I feel your pain. I went through a total nightmare with my last build trying to hit those numbers and it was honestly soul-crushing... I spent like three days straight just staring at memtest errors. In my experience, 7200mhz is really the practical ceiling for most of these four-dimm boards like yours. You might want to consider that the Z790-E just isnt built for 8000 like the specialized overclocking boards are. I would suggest being really careful with the IMC on that 14900k too because some chips just cant handle it no matter what you do. Its kinda like a lottery tbh. Before you give up, are you strictly looking for 8000mhz or would you be okay settling for something like 7200mhz? Also, are you updated to the very latest BIOS?
