Guys - is the Vcore/VCCSA/SysAgent all three in 1,28V safe ?
Someone wrote here that SA/VCCIO should be 0,05V difference ?

Testing now 1,260V on all three settings.
Cpu drops to 1,248V. IO drops to 1,243V.
Three tests passed without errors.

And was that starcraft or starcraft 2 in the background? lol

Didn't need 1.4v to boot into windows. This is XMP + 4200
Also put the 4133 @ 1.4v (enhanced performance)



Now you got my itch going again

btw, on the aorus master with a 9900k, you can do CL 16-16-16-36(or 34)-372-65534-2T @4133mhz with 1.45v vdimm/training voltage or less and with 1.25v sa/io or less with that kit as long as your IMC is decent and as long as you have enough case airflow for the dimms.


Please do me a favor since you have the same kit. Please try to train 4200mhz with those dimms using auto motherboard timings. What timings does it give you? You should be able to train it with dram voltage on auto and sa/io 1.25v but once it trains, go back into bios right away and raise the dram/training voltage to 1.4v or 1.43v to get into windows. Then please screenshot the timings in asrock timing configurator and post here. Let me know if you need asrock timing configurator.

Nw, hopefully you'll yield better results with the memory but note Kedarwolf had all his timings set (he spent quite a bit of time on the 24/7 stability thread)

Honestly I'm pretty happy with these, Apex finally isn't crashing at max pl + oc scanner (I knew it wasn't the card giving errors)

Fair enough.

I'll have to try out kedarwolf's method, I never tried that before. I wonder if it will yield better latency or if RTLs will train better or w/e. Right now i'm getting 38.x ns latency at cl15/4000, i don't know if that is where it should be or not.

Yeah I guess I can't really offer much advice on your set up, just kind of out of my realm of knowledge, sorry mate.

These are more or less stock settings, but running a constant frequency.
Don't like my voltage jumping all over the place.
If I go by Falkentynes recommendation of ac/dc 100/160 I get an unequal residual every once in a while, these settings provide equal residuals after 16+ h powered off.

Regarding the memory, this seems to be completely stable, I copied how Kedarwolf did it (same kit as yours)

I was always under the impression we were supposed to boot with xmp profile, then modify the timings/frequency of the xmp profile after xmp has already been trained. Have I been doing this wrong?

still looking at your settings before I can give you a definitive opinion.

Ok, after looking at the settings, I can't really say whether it is optimal or not, I don't tune with anything other than dvid mode or the basic set it and forget it fixed voltage mode. I'm not too great at balancing the higher acdc settings. Am curious about the ram thing I mentioned earlier.

I am curious though, Why not just run stock if you were going to run 47x? You'll get more performance in other areas while still having your 47x all core multiplier.
