Hello at stock settings with ASUS Multicore Enhancement I had all cores boost to 4.7ghz but I didnt take note of the voltage but temps was below 60c with Corsair H100

I went ahead and enabled XMP for my DDR4 Ram to OC to 3200mhz and now my CPU only boost at all core 4.4ghz
Do I need to manual OC now because of enabling XMP?
 
Yes manual overclocking is better to fine tune stability, overclock your cpu first then enable Xp .

Should be able to find a guide on the web
 
Enable xmp and OC at the same time is the best option as OC of cpu and memory effect each other.

Should be easy.

Set xmp
All core 47
Cache 44
Digital power cpu curent cap 140%
Vcore 1.3v
Vccsa 1.12
Vccio 1.1
Cpu standby 1.1
Dram voltage 1.4

Done.....

Hello
I have followed your settings and everything been fine for couple days. What I have noticed though when playing games all cores will be at 4.7 but randomly one core will drop down to 4.4. Temps are very good all cores below 60c
 
Maybe try with zero avx offset.

You can look check windows power plan.

Some games are not using all cores so they may also drop when not loaded.

With your settings you always have cache 44 min/max - is this stability or performance as I assumed higher would be better but not tested much yet.

Running the same ratio as core now (51 for 24/7 use).

Cheers!
 
For stability yes. Core can often go higher then. You can gain some efficiency by overclocking cache too so after you max out core then test incremental increases in cache.
 
Hello been running stable with all this set
Set xmp
All core 47
Cache 44
Digital power cpu curent cap 140%
Vcore 1.3v
Vccsa 1.12
Vccio 1.1
Cpu standby 1.1
Dram voltage 1.4

But I noticed even with voltage at 1.3v in the bios Hwinfo64 is reporting max 1.485 is Hwinfo just reading things wrong here?

Isn't that the vid?

Noticed that too, been using CPUz for my readings.
 
Hello is 1.2 VCCSA and 1.2 VCCIO too much ?
I been getting a GPU driver crash only in one game FORZA 3 and google people seem to have fixed it by increasing these voltages to make the system more stable. I was using 1.1 on both perfectly fine apart from this one game.

This game does really push my system a lot more then other games I would say so I can kinda see why this game would crash a unstable system.
