z690 Formula - Detect memory

[axiumone]

I've had this board since launch. In the begging, I had it with 4x16GB sticks from two corsair kits and with early bios revisions that was a nightmare. Fine, I've sold the kits and switched to a single 64GB kit. I was hoping for plug and play. Just XMP is enabled.

I need stability out of this rig, and I'm having two big issues. Every couple of reboots, I'll get stuck on memory detect while booting. I'll have to power cycle and it'll kick me to bios saying it couldn't boot, I'll go into bios and without changing anything, it'll keep working for another couple of boots. The other issue is win 11 refuses to wake from sleep. Instead of waking the system, it will reboot. Bios is 2004

Hello,

You'll need to tune the system. You can try using XMP II as this is the default DIMM profile with slightly loser memory subsets.

Try bumping VCCSA (CPU System Agent). 1.05 - 1.15v

[axiumone]

XMP I or II produce the same results. As you can see in the screenshots, MC voltage is already at 1.25. How much more can I safely raise it? I’ll try raising VCCSA. *

This is a pretty slow ram kit. Why does this require tuning besides turning on xmp?

Edit - Raising VCCSA to 1.15 seems to have helped. System wakes from sleep as expected and no memory detect after a couple of reboots. Thanks!

Nothing changed in voltages or system config. Now it's back to restarting when waking from sleep.

Tried VCCSA voltages from 1.1-1.4, no affect.
Tried setting the speed to 4800mhz, no affect.
Updated bios from 2004 to 2103, no affect.
Tried slots A1-B1, system wouldn't even post at anything above 4000mhz.

The system just reboots instead of waking from sleep.

Running memtest right now. It looks like the memory is not defective, so it must be the motherboard or bios.



Why is it that a set that is on the QVL list for this board doesn't work with just XMP settings?
Why aren't the settings posted that the set was used with for QVL testing?
Is the motherboard defective?

[axiumone]

Asus? Anyone? My workflow changed and it's imperative that this motherboard restarts and wakes from sleep without fault. Between the PG42UQ having massive issues with firmware and this motherboard having huge issues with networking and now this memory problem, that's over $2000 usd tied up in faulty asus products.

I have 2x16GB Corsair 5200 sticks in a 690 Hero. They are the non RGB sticks. They run at 5200 with XMPI just fine. Never had a stability problem with them and just about all of my other mobo settings are on defaults.

If it helps, I have taken a screenshot of my memory voltages from HWInfo below. Also, in CPU-Z I get exactly the same timings as you. The only difference is that mine says 32GB, yours says 64GB. Otherwise identical. I was going to suggest 2103 BIOS as I've seen no complaints about that version, but you have already done it.

You say you have a 64GB kit. Is that 2x32GB or 4x16GB? If the latter, have you tried just 2 sticks instead of 4? Maybe see if that helps stability for now?

The columns in the screenshot are current, min, max and average

I have similar issue that related to RAM and memory detect issue with frequent crash during gaming or stress or sometimes not posting and showing memory detect

[axiumone]

I'm still having the issue. What does QVL mean to asus? What was tested? What settings were used?

This kit behaves the same even at the kits JEDEC settings of 4000mhz. Corsair support says the kit is fine. That means its the motherboard.

I have two ram sets of 16 GB x 2, one is ADATA 4800 and one is G-Skill 6600, both works only on A1, B1 slot with 4000mhz. Not posting on A2,B2 and showing memory detect issue.

after many trial. it works now only on B2 with 6600 but putting the other ram on A2 slot show memory detect issue. putting single ram in A2 also memory detect.

I am not getting any help. its either MB problem or some bios tweaks needed.
