Crucial Ballistix 4400mhz ram XMP issue :( I hate asking for help but sometimes you just have to.

[cmmyers51]

So, My current system is a Intel 10900K with a NZXT Kraken X73 AIO. X490 Vision G Motherboard with 32gigs (16gig x 2) 4400mhz memory (crucial Ballistix) and a ROG strix 3090 graphics card.  With the Z490 I could not get any stability out of the XMP for 4400mhz at all most I could get stable running Memtest was 3800Mhz. Technical support was basically useless, gigabyte telling me to contact Crucial and Crucial telling me to contact Gigabyte. So yesterday I installed a Prime Z590-A motherboard and am getting stability issues also so I bought another 32gig ram kit and same result, everything is updated if I had hair I would be pulling it out.  I am basically hoping someone on here has some experience with this so I can finally get my system running to its full potential.

Dumb question, perhaps, but have you confirmed the sticks are in the correct slots?

[cmmyers51]

Yes lol

The IMC lives on the CPU… it’s likely your CPU can’t handle RAM that fast. Remember, XMP speeds are not guaranteed to work, they are an overclock.

 

You can try bumping system agent and VCCIO voltages to try and get it happy. Basically you will need to follow RAM overclocking tips. But it’s almost certainly not the mobo or the RAM, likely the CPU.

Slot Number 2 and 4 if you count from the left?

 

Seems like you need some VCCSA and VCCIO adjustments, what does the mobo run at stock? I typically go for 1.3V SA and 1.25V IO

[cmmyers51]

yes it is DIMM_A2 and DIMM_B2 according to the manual. Stock the Mobo is running 2666Mhz.  I will give it a shot.

There is always a chance that you are a bit unlucky in the silicon lottery. 4400mhz is not really a standard in DDR4 and it's a pretty hefty overclock.

I somehow think that you will be only able to achieve it with a manual overclock, instead of the standard XMP settings. It can depend on the system too, but yours seems it should be able to do it.

if i had to guess it's SA/IO too, never heard of z490 choking at 3800, manually check ur timings/voltages instead of just xmp

Also of note, more VCCSA and VCCIO don’t necessarily lead to stability. There is a sweet spot for every CPU, and more isn’t by default better. 
 

RAM overclocking is a massive PITA, I would do some YouTubing, and if reference: https://www.reddit.com/r/overclocking/wiki/ram/ddr4#wiki_corsair

 

And I would also use better memory stressing programs, memtest isn’t bad, but there are better listed on that page as well.

Thank you guys for all the help, After setting ram overclock manually instead of using XMP and setting the recomended VCCSA and VCCIO.  It went through a 45min memtest with no errors.  You guys are great
