Great job!!!

I already told you all, for booting 7200 all slot used and bench it, i need to bin cpu and memory.

Here you go

Thats very good result for the mem clk, you need more memory clock to do it better i think. Try to run at 4000 c12 or more. You need high sa like 1.35v-1.45v, and more vddq, maybe 1.35-1.55v is fine for benching. I did 4080 c13 with asus prime is all hot ambient air in Indonesia

Usually is like that, you cant rma cpu that cant do 5500 daily on water, or cpu imc that cant do 7200 quad channel. Because intel only accepted if your cpu imc failed 4800 jedec spec as on intel ark specs. Anything above that is overclock. And remember now ddr5 imc is having 4 channel, and every channel is different. Channel A better than Channel B, and slot B is better than slot A. You need combination to make all works.

Just rma it, no need to spam it here. I dont think anyone here is customer support. Just FYI, i changing memory same hynix 3 times, 2 kit did 6666 ycruncher 2.5b, and 1 kit did 6933 ycruncher 2.5b. And there is cpu imc variance too, i cant do 7200 geekbench without cpu limited to 2c/2t or what it mean is cpu imc need cold.

And you already have the money back is it? Or not? You same people on ocn forum right? I only silent rider there. Dont expect very high xmp kit to be stable easily, on any gen and any specs. And variation board to board is there as always have been since old day, just because clock is now higher many people just realising it now.

Sorry for you guys who have problem with DDR5. On DDR4 i have issue with 5066 Kit that is error on xmp, and thats not board or memory issue, its IMC issue, and this on rocketlake. I can bench geekbench to 5866 and memory clock 6300 but no 5066 stable at xmp. XMP is overclock.

Crazy score, CPU, memory, and run!

Nice result and nice mem!

Great job!

DDR5-6933 30-40-40 passing Y-Cruncher 2.5B on 2021 board with 9902 BIOS

DDR5-7200 32-42-42 2T Quad Channel done on 9902 BIOS finally!

Crazy run great job!

Great job!

Just try the settings above, i wait your feedback if it fixed your problems

Anyone who said who have problem, my board is 2021 too and i dont have problem, i can run Y-Cruncher 2.5B All Days on this setting and actually i use this settings for daily use. This settings may help you if you have problem. Try this BIOS, this is best BIOS for mem oc from anything i try. BIOS thanks to @shamino https://www.dropbox.com/s/qb4qbqdzae5e3d2/ROG-MAXIMUS-Z690-APEX-ASUS-9902.zip?dl=0 And try this may help stability, thanks to @safedisk SenseAmp Offset Training [Disabled] Read Timing Centering 1D [Enabled] Round Trip Latency [Enabled] Turn Around Timing Training [Disabled] And i try this helped too : DRAM CLK Period [63] to [161] Dll_bwsel [24] or [25] Memory Controller Voltage [AUTO] CPU System Agent Voltage [AUTO] or some CPU may like it 0.9 to 0.975v IVR Transmitter VDDQ Voltage [AUTO] DRAM VDD Switching Frequency [1.5] DRAM VDDQ Switching Frequency [1.5] DRAM VDD & VDDQ is depend on Memory IC and PMIC can be different.

With that timing and voltage, most probably Samsung B-Die

Great result!

GG, nice cpu and nice job!

Crazy clock!

Nice score! New steppings cpu seems good!

Great result!!

7000 30-40-40 2T Tight working on 0080 BIOS, definitely improving it!

Nice works and nice score!
