Problem with XMP boot setup. Need assistance!
The additional 4-pin ATX power doesn’t improve stability. The EPS 8-pin can handle up to 336W for the CPU—more than sufficient for an i9-9900K. You’d only need this extra power if you’re attempting extreme overclocking requiring over 350W for the CPU. Are you using a single 4x8GB package or two separate kits? The BIOS showing DDR4-3000 and suddenly listing DDR4-3200 as an XMP profile suggests two 8GB kits, one DDR4-3000 and another DDR4-3200. The part numbers and revision details are usually on the heatsink labels. I’m puzzled why the i9-9900K wouldn’t run with four modules at DDR4-3200. It might be similar to my experience with the i7-8086K, which ran four 8GB modules at DDR4-3600 CL15 using Samsung B-Die DDR4-3000 CL14.
I previously managed this board and BIOS, but the ME firmware is quite disorganized. You could try setting the XMP profile manually. Just note the main clock speeds and DRAM voltage, turn off XMP, adjust the DRAM speed to 3200, and use the standard voltage specified.
Well, when I enable auto, it keeps the other RAM speeds at 2133 and I'm just setting the MHz to 3000. My worry is that it's not receiving any voltage changes or other adjustments XMP would provide. @DoctorNick Should I switch to XMP 1 (ASUS settings) or XMP 2 (Corsair settings)? Then record all the technical voltage settings? Or just focus on frequency, 1.35 and that's it?
Damn, I just realized.......................... When i bought this ram i never bothered to check all 4, i must have only checked the top two......................................................... Gosh I feel dumb now. Well at that point. Do you know if theres nay way i can configure the ram to get the XMP 3000 profile? Like put the 3000 in slots 1 and 2 and the 3200 in slots 3 and 4? Or should i do dcotor nick said below and just set xmp off and set frequency to 3000 and voltage to 1.35
I suggest verifying the components. If you have two mismatched kits, place one in Slots 2 and 4, the other in 1 and 3. [-- CPU Socket --] [Slot 1] [Slot 2] [Slot 3] [Slot 4]. The motherboard typically applies identical XMP profiles to all DIMMs, which may explain why DDR4-3000 isn't functioning, as it's the slower option. It might be due to Auto memory timings not matching. Try setting the frequency to DDR4-3000 and DRAM Voltage to 1.35V. Unless the board requires additional time or needs multiple retraining attempts.
After going through the troubleshooting, I realized I should have chosen XMP 2 instead of XMP 1. The Asus BIOS is clearly not working well, so sticking with the Corsair preset (XMP 2) seems like the better option.
