Did some expiramenting with Dark mem oc. 4800 is harder for some reason.

@DerpFails
are you still using 8700K?
With 8700k is mem overclocking a little bit easier than with 9900k/kf/ks, nevertheless very good resutls!
Can you also run benchmarks with it?

Best I have is 4800 14-13 2t waza and 4266 12-11 1t gb3. You know me as Sparky's__Adventure on HWBot.

I don't bump it back down after training. I am unaware of any correlation between high sa/io and imc degradation, that doesn't mean that there isn't any though. I just haven't seen it yet at my side.
When I was testing the 390 dark alot, I was beating the hell out of some 9900k cpus 1.55+ io/sa for the really high 4900mhz+ LL benching mostly on air cooling too. Kept working well every session without any decrease in overclockability that I could tell.

Do yall bump VCCSA/IO back down to under 1.4 - 1.45 after training?  When shooting for High-ish Bdie clocks? or Leave it up at 1.4/ 1.45 for the entirety of the bench session?
 
In my small sample size of 3 9900K's I can't get training @4300+ w/o at least 1.4v SA and I am pretty sure my chips don't enjoy long exposures to 1.4v sa/io.
 
One of my CPU's after running 1.45v SA for about 5 bench sessions of ~5 hours per session decided it only likes at least 1.375v+ SA regardless of clock.
 
Which i correlated with a degradation of IMC associated with SA V at 1.4v but I didn't know how to validate that theory and am mostly just in a state of perpetual speculation and assumption. #feelsbad
 
 
 
 








 
Do you run 1.450 sa and 1.40 io as a daily for that rig or just benching? And are you still running it? Have you run into any issues from from those voltages? And your samsung b-die is still fine from running 1.650 volts on the dram daily right? No issues with degradation or stuff like that? - Just curious about the sa and io since some people say 1.40 volts on both of them are the max voltages you should use on a daily, and your comment said you haven't run into any problems yet.

"I have 4 sticks passively cooled on x299 DARK rig running at 4000 cl14 1.65v daily. Never changed the voltage from there and running nearly one year straight without much shutdowns at all and no issues yet. I also know some guys to literally use 2v on their daily testing rigs with no issues as well lol. Id's say 1.55-1.65v with moderate OC is np longterm." - Kingpin
 
I assume the shutdowns are from powering it down? you don't power off your computer usually?
