z690 Formula - Detect memory

[Optimiser]

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.

I have a similar problem on my ROG Strix Z690-F Gaming WiFi when it comes to memory in-slot recognition. Only B2 works! I can therefore only use one of my 2 new 16Gb DDR5 G.Skill 6000 Trident Z5 sticks! Tried all the bios's except the last 2 that won't let you wind back and am on the last one before them.

Hello 0ptimiser,

Welcome to the ROG forum.

I also have the ROG Strix Z690-F Gaming Wifi with 16GB (2x8GB) Kingston Fury Beast 6000MT/s cl40 overclocked to 6200MT/s 34-36-36-40-2N timings in Gear Mode 2.

I'm on the latest bios 2103 and I find this bios to be the best so far.

If slot A2 is not detecting your memory at default settings, you could try loosening your cpu cooler a touch. If that doesn't help, remove your cpu cooler and cpu and check for any bent or misaligned cpu socket pins with a magnifying glass.

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.

Try raising VDD and VDDQ to 1.30 - 1.35v.

Please see the first post. The bios settings are there, including what you're suggesting.

Hello,

will the CPU cooler pressure affect the A2 and not A1 ?

Mine sometime post but crash during stress or gaming, and sometimes doesn't post at all

Hi ssstrong,

A cpu cooler that is too tight can warp the pcb and cause issues such as yours, bent cpu socket pins can cause this issue too.

With both sticks installed in slots A2 - B2, enter the bios and hit the F5 key to reset to defaults.

Both sticks should be detected at default settings, if they are, it's possible you just need to adjust some voltages.

Thanks Nate, I've remounted the cooler a few times. No change.

I opened a ticket with corsair. After troubleshooting, they're pining this on the board or the bios. Now what?

I've finally got my 2 x 16 Gb DDR 5 DIMM sticks to boot properly (together) but ONLY in B1 and B2 mem slots respectively. This was only since updating to BIOS 2103 with memoery at 1.35 Volts and using either no XMP or XMP1, NOT XMP2. DIMMs will absolutley NOT work (boot) in A1 or A2 in any combination of 1 or 2 sticks, so I only have dual channel not quad.
I do not believe it's anything to do with CPU cooler pressed down too tight or bent socket pins. I Do believe it's an issue with the motherboard itself!

Hello guys, can you look at this video please

I'm on the latest bios 2103 and I find this bios to be the best so far.

Hey, Nate, I also have Z690-F, and I'm a bit scared updating to 2103 from my 1304 due to no-rollback issue.
At BIOS 1304 my G.skill 6000 cl36 seems stable at XMP and even allowed me some overclock to 6200.
But later BIOSes (1505, 1601..) couldn't even handle the XMP right. And a lot of complaints for all of them here ta the forum.

What you think - shall i try 2103?
