The average 11900K has SP 70+
Above average/good SP 80+
Really good / lotto winner 90+

special tweak only engage for short range below 4000 to be safe
so added tweak to maximus tweak mode 2 for a much wider range without affecting normal XMPs: just choose mode 2 in below bios
this also has the eventual vtt voltage cstk1 asked for
m12

What bios is the M12A bios based on? I assume 2103.

i9-11900K (SP89) @stock---4800Mhz-C19-28-28-48-1T----1.66V---SA 1.2V---MCIO 1.26V---Stressapptest----1 Hour

2488354


Trying mem OC on my SP89, turns out the IMC is a lot more finicky requiring specific voltage ranges for SA/IO to stay away from errors.

My SP85 would train 5066MHz C20 1T easily though it needs a little more voltage in the IMC and does away with 10-20mV less VDIMM at each frequency point. SP89 has a noticeable hard wall with memory scaling, mostly no POST up till 1.4V SA/IO for 5066 C20.

Might attempt 5066 C20 1T GSAT 1H on my SP85 soon.

odd. i havent seen 11900k on gear 2 showing any diff on imc ..

maybe gear 1 or the upper ranges of gear 2.

interesting.

you verified your cpu sp on which board bro?

Yes it's probably going to be the upper ranges of a daily OC.

What would be regarded as safe SA voltage 24/7? Currently running 4 x 3733 CL14 with 11900k SP94 and 0707 BIOS on MH13. Was hoping to push it to 3866 for now before venturing into gear 2 mode.

Can anyone recommend timings to tighten for sub 40ns? Currently ~43-44ns in AIDA just using BIOS mode 2. Complete n00b with memory OC, I usually just follow guides and hope for the best with each new build.

Asrock timing config isn't reading timings correctly, any idea why?
