Question I9900K + MAXIMUS XI EXTREME + GSKILL F4000C17 Issue, Need Assistance :(
Ty liquid again.
If i try to put avx 1 or more system crash istant when i start cinebench, now i reach 2120 as score, but after 20 min prime crash and system put me in the bios where he adjust dram voltage from 1.35 to 1.40 and VCCIO and system agente voltage to 1.35.
Which parameters i have to modify to keep stability?
My ram are F4-4000C17Q-32GTZR
Thanks very much again
What prime are you running. Shouldn't use higher than 26.6 due to extreme stress from AVX power draw. More details on this can be found. I'd recommend realbench. Have you tried lower VCCIO/SA? Usually, there is a stability window. To low or high can cause issues.
I attempted the version I wrote earlier but the system crashed again after 15 minutes of startup. I’d like to try without using XMP and just aim for better CPU stability. What are your thoughts?

Yes, proceed solely using CPU OC settings, excluding XMP or memory tweaks. Maintain the stock voltage of 2133, without applying XMP until the CPU is properly optimized. Please specify your maximum acceptable CPU voltage and preferred OC type—whether you need AVX at 5GHz or a lower frequency, as most applications don't require it.
Regarding the maximum voltage on the CPU at a given temperature, I’m not sure of the exact number, but in my room it’s around 27-28 degrees, so higher temperatures might require lower voltage. I plan to test 1.32 volts per core.
I'm working with 1.325v and an AVX offset of 1. Referring to core/cache performance at 5ghz. If stability isn't achieved, I'll test offsets 1, 2, 3, then 4.9ghz at the same voltage. My goal is to identify your CPU's limits. Should I use 1.3v as a safe starting point? Are you applying manual voltage control? Your cache is currently at 4.3ghz. I recommend using an LLC7 controller to reduce voltage droop, assuming your board specifications match. Avoid using 8 since it can cause overshoot.
I believe I can proceed with 1.33, but I haven't verified the temperature. Let me check the cache stock 4.3 and LLC6. Now I attempt the version I previously mentioned; if it crashes again, I'll adjust LL6 to 7 and AVX 1.
I attempt to reduce speed to 4.9 at the same voltage, but the system remains unstable. I believe sending back this CPU might help.
