AMD 7950x with g.skill xmp

Hi,
I want to buy RAM sticks for a new computer with an AMD 7950x processor, a Gigabyte x670 aours Elite ax motherboard. I chose G.Skill Ripjaws S5, DDR5, 96 GB, 6400MHz, CL32 RAM (F5-6400J3239F48GX2-RS5K) but it only supports XMP. Is it a good idea to buy these ram? The voltage of these bones is 1.35V. I care about at least 96 GB memory. Is there any other better choice? Is the EXPO profile better than XMP?
Please help.

Everything works as it should, the processor runs at 6400 MHz, it is the same memory - Z5. The motherboard is Asus x670E-A. I recommend G.Skill

Unfortunately, the Aorus Elite AX board does not support any 48GB sticks on the list.

I run 2x32GB GSkill Ripjaws S5 XMP 6400 CAS32 (Hynix) with my 7950x on an ASRock B650E Steel Legend .. not quite the same  ..but they run pretty darn good

Just be sure to update your BIOS to latest version for your motherboard

On your board, my selected RAM sticks will work without any problems. this means I have to change the motherboard. How is your motherboard performing? Is the BIOS clean or slightly modified?

Stock BIOS from ASRock .. if that is what you mean

I run a PBO preset of 85C TJMax, CO -30mv all cores, GDM = off , MCR = off, PDM = off, +25 core boost, AGESA = Competitive (auto clocks subtimings a bit more aggressively than Default)

..and though XMP works great at 6400 32-38-38-38-102, DDR voltages 1.4v, SOC 1.3v, UCLK=MCLK/2. Changing to UCLK=MCLK (1:1) is not stable on my rig at 6400 .. so I get better performance running @ 6200 30-36-36-36-78, DDR voltages 1.35v, SOC 1.21v, UCLK =MCLK

Some of ASRock BIOS settings might not make sense to non-ASRock users .. I'm not sure what the Gigabyte equivalent would be .. like PBO presets or ASRock's AGESA settings

that is great to hear. mine posted a BIOS message that there was an error detected. I had to get a new 6000 MHz kit. i'm very disappointed with my machine.
