What motherboard are you using?

gigabyte z390 aurus ultra with latest f7 bios.

Even if i just enable the 'multicore performance' mode which locks it to 5ghz i'm seeing vcore upto 1.5. Either my cpu sucks or the mobo is trash.

I've followed multiple guides, varied techniques, even used loadline extreme and nothing can keep it stable unless i pump in about 1.45 vcore just for a stable 5ghz
 
Im using a gigabyte board.
Here are my settings:
Core multiplier 52
Dynamic vid offset +100
Llc: turbo
Vcore current protection: turbo
Vr ai ac/dc: both set to 1

Maybe you could try these with your 50x multi. The ai ac/dc is important with the positive offset otherwise id see vcore as high as 1.4v. Set to 1 vcore max spike is 1.304

Also, i use vrout in hwinfo64 to monitor the vcore. This has been tested as the most accurate reading. It is the one that Asus boards use as standard. It also explains why Asus board users report lower vcore many times.
I notice my vcore reported as 1.3 via vrout, can be as high as 1.37 on the other sensors and its the higher value that is used as default on other monitoring softwares.

One and a quarter hours into Aida64 stability test, 5.0ghz with 1.190v set in bios, 1.172v under full load LLC7. Max temp 70c. Don't use AVX/FPU.

30 minute run of RealBench using same voltage, load voltage 1.172v, as above post, highest temp 79c, as we know RealBench uses AVX instructions, hence the extra heat produced. ;) Screen shot taken after RealBench had finished, but load voltage is shown as Minimum in HWInfo64.

Under load voltage. 1.172v

my bios will not let me change vr au ac.dc fir sine reason and i can't find vcore current protection either, just llc and internal acdc loadline.

I know the ultra bios has only half the o.c options as the master version, it's so stupid and i wish i knew this before buying it. Doubt ocuk would swap either as the box is damaged.

Is the IA ac and dc loadline in the vr settings? Im pretty sure my friend with an ultra was able to change this. It may have been bugged on an early bios. Meaning entering 1 then pressing enter bugged it out.
I will have a look later to see where the current protection setting is and update here.
 
Nope. They're releasing the new SKU without the active igpu but thats about it. I doubt there will be an update to the current lineup. It seems like Intel are right at the edge with this process node now so until the architecture changes or we get a node shrink i think stepping revisions are unlikely.

At least in the consumer space.
