GSkill 6400 with 13900k

[Hopper64]

Still can’t get a stable result with this memory kit on my MZ690E with a 13900k. Part is F5-6400J3239G16GX2. Tried VDD/VDDQ 1.435-1.45V with no success. Reviewed shamino’s notes previously and tried 1.435-1.45 on VDD with VDDQ at 1.25V and VDDQ Tx 1.435-1.45 and no success either. MC was at 1.35V and noticed it was a bit more stability with manual SAV 1.15-1.225V. Higher SAV seemed to be more unstable. XMP 1 and 2 don’t pass TM5 and Ramtest. Just using manual settings and dialing in the primary timings. Rest set to auto. Suggestions? Thanks.*

I wonder if this is related to the issue I was having: https://rog.asus.com/forum/showthread.php?130980-Is-anyone-running-a-13900k-with-a-STRIX-Z690-E&p=87...

I'm using a similar kit F5-6400J3239G16GX2-TZ5RK

Don’t think so. I was having the same issue before the 13900k. Just can’t get the memory stable.

I have this kit and it works fine at XMP with both a 12900K and 13900K. You might just have bad sticks, hate to say it... and if you've tried on multiple CPUs there's a better case for that.

It also won’t work on 2 different z690 motherboards. But it passes at default settings. That’s why I am thinking it’s the OC and not the kit itself.

those 690 MBs were Asus as well?
probably will have to wait for a Z790...

tried these?

Hello,

Easiest way is to tune the CPU System Agent and Memory Controller voltages. Test incrementally.

CPU SA: 1.00v - 1.15v

Memory Controller 1.2v - 1.35v

Try using either Tweak Modes 1 or 2

Try Selecting XMP II (Default DIMM profile)

Use Karhu RAMTest to test stability (1000% - 2000% coverage)

maybe the Z790 will solve the issue...

Yes. Tried all those. Both Asus boards. And yes, just starting to test a MZ790E and so far a 6000 GSkill kit is working with no issue. XMP 1. Never had success with that on Z690. Getting detect memory error with the 6400 kit and waiting for input from Asus on that. Thanks. Â*

can't believe that even with Z790 Asus can't run a simple 2x16 beyond 6000 =))
and that bloody Z790 Extreme mobo is 1500-ish euro, as Z690 Extreme was at its time - now they "discounted" to 1100-ish Eur :))

But to be clear I’m getting detect memory errors code 55 ONLY with the 6400 kit at default so I believe it’s a simple bios issue that needs to be fixed. It’s peculiar that it boots and will post with the 6000 kit at default but not 6400. I’m not sure what’s going on yet so it’s difficult to draw any conclusion at this point. 🙂
