Why won't my RAM run XMP stable?

Hi

I have a Z690 Gigabyte gaming x DDR4 Motherboard with 12900K with the latest BIOS version which is F8.

The RAM is Corsair vengence 4x8gb 3200mhz. It's fine at the stock setting of 2333mhz I think but when I set it too XMP in the BIOS Elden Ring will freeze after about 30 min but never when its at 2333mhz.

Is this faulty RAM or something else?

Thanks!
 
My Z690 never sets the right voltage even though it’s part of the XMP profile I always thought. I was having stability issues for hours until I realised my ram was set at 1.2v and not 1.35v which I had to setup manually.

Make sure it’s not doing the same thing (mine is also a Gigabyte board).

Despite lots of bios updates the z690 still seems a bit odd sometimes…

My older Sandy Bridge board didn't set XMP voltages properly either, also Gigabyte. Manually set the voltage on top of the XMP profile and see if that helps.
 
I tried setting 3200 manually and set the voltage to 1.35v but still crashes Elden ring after roughly 30 min.
 
Is your memory actually supported in XMP configuration on the board for 4 sticks? 4 sticks has a lot more strain so typically not all boards will support xmp in 4 stick configuration.


I would check on there whether 4 stick and xmp is ticked for your memory kit.
 
Did a quick google and you are not the first to encounter DDR4 issues.


My 12700K SP70 is game stable (with E-cores disabled) at 1.182V Load (LLC 6 on Strix A, 1.190V set in BIOS I believe, manual voltage), but for it to be R23 stable I had to increase it to about 1.22V, so roughly 40mV higher, I haven't measured exactly what it needs yet but since I've been testing memory I just increased voltage to about 1.24-1.25V Load, to ensure complete stability, and that's with 5.0GHz (50x) Sync All Cores, C-States Disabled, Turbo/SpeedShift/Turbo 3.0 enabled, and Cache/Ring on 4.7GHz (47x). I do have a beefy radiator setup for the processor though, triple radiator and the water temp never goes more than 1.5°C above ambient when gaming at ~100W.
I have been out of the loop for quite a while, what's the Gigabyte track record like? How quickly if at all, could one expect issues like these resolved? We talking about days/weeks/months?
It's quite weird none of the media has picked this up since running even stock speeds and timings seems impossible at the moment and it should affect all users. Number of reports of the issues are still somewhat limited and quite hidden in various forums.
I have no idea, I dislike Gigabyte products with a passion, not because I have anything against the brand itself per se, it's just that all of their products are rather.. poor, and that's just a fact. GPUs, Motherboards, Power Supplies, doesn't matter, worse than all of the competition, in general.. (there are always exceptions), they've had some good boards over the past few years but they've been very, very rare. So, I don't own anything Gigabyte and thus lack any deep insight in their track record, such as BIOS updates, which you would only know about if you owned a board, but to be clear, so you don't think I'm sounding like a "fanboy" of any such nonsense, I did buy a Gaming X and Elite AX for Z690 to test out and very likely keep, that was the plan, because on paper they are literally the best boards, unbeatable price/performance, but nope, BIOS is basically pre-alpha by the looks of it, they clearly don't care, since it's been a week now and still no BIOS update. So vote with your wallet I guess, support brands that know what they're doing. If a BIOS update isn't out within the next 5 days, I'm not even going to bother testing the boards, not going to waste my time messing around on a broken BIOS (and yes, it's literally broken, I had the same bug as Cuthalu but on my Elite AX when I tried it briefly a few days ago, I brushed it off as something I did wrong, gave Gigabyte the benefit of the doubt, but after seeing Cuthalu encountering the same problem on a different board.. literally just broken BIOS).


So I don't know what to say. You could try 2666 speed with auto latency timings and then go higher from there but XMP seems definitely out of the question.

I would probably have to spend an afternoon tinkering with the settings to see if I could manually get the BIOS right but I can't tell you over the forum. There are so many variables you need to look at with issues like this.

Are the auto settings to aggressive? Do you need 1.45v? Have you manually set the SOC voltage? Is the motherboard trying to auto overclock via BCLK?
 
I also seem to recall Buildzoid complaining that DDR4 overclocking with gigabyte Z690 motherboards being a massive issue.

Try this video for info but I'm at work and don't have the time/can't be asked to watch it again

 
Thanks guys, wil spend the weekend looking into it more and see what happens.

More voltage!!! When all else fails memory wise throw voltage at the dimms and a bit more at the uncore.

I have to agree with this. I always add more voltage to my DIMMS until I hit a heat/stability wall and then reduce it.

I also think LLC is an under utilized function. What you taketh away with manually set low voltages, LLC adds when the system is under stress.

I would also point out that often auto voltages are dangerous/too low and manually setting the voltage is key. Use CPU-z to test if the voltage is accurate (or as accurate as can sort of be with software monitoring).
 
Pretty sure you run two sticks it's fine... Z690 is not great with full dimm population... However should work with careful sa, io tuning....

To test ram ideally you run a ram testing programme also to find any specific issues with each stick...

I have found Y-Cruncher to be really good for testing stability of both RAM and CPU, so far every time it has passed 2 runs the memory is stable in Memtest86, use as much of your RAM as possible.
