Is the ASUS ROG CROSSHAIR X870E APEX marketed for memory overclocking?

Yes, the ASUS ROG Crosshair X870E Apex is absolutely aimed at people who love pushing memory speeds. This isn’t your “just plug it in and forget it” type of board, it’s part of ASUS’s Apex line, which is famous for extreme overclocking, especially when it comes to RAM. For starters, it only has two DIMM slots instead of four. That’s not a downgrade, it’s intentional. With fewer slots, the signal path to the memory is cleaner, which means you can crank up DDR5 speeds without stability issues. ASUS even throws in a ROG Memory Fan Kit so you can keep your RAM cool when you’re pushing it hard, and they brag about hitting 9000 MT/s and beyond. The board’s power delivery and cooling setup are also beefed up so it can handle extreme tuning, even if you’re doing liquid nitrogen runs. And this isn’t just marketing hype people have actually pushed memory past 10,200 MT/s on it, even with air cooling. So yeah, if your goal is to squeeze every last drop of speed out of your DDR5, this board was pretty much built with you in mind.

Is this a question? Nope. I'm just mad it got delayed. :(

I pre-ordered it almost month ago within first couple of days when it was up for pre-order on Newegg. I believe I was one of first who placed pre-oder. Now I got notification that the shipping is delayed by more than a month! I still hope that for early birds like me it won't be more than a couple of days delay. Anyway this is very disappointing Newegg!

Already sold out. I pre-ordered and mine shipped on May 8th

How many DIMM slots does this motherboard have?

This motherboard has 2 DIMM slots.

Does the ASUS ROG CROSSHAIR X870E APEX have a RAM cooling solution?

Yes, the ASUS ROG CROSSHAIR X870E APEX includes a ROG Memory Fan Kit as a cooling solution for RAM, designed to enhance memory overclocking performance.
