I would definitely try higher values! Try with 1.15-1.20v and if it helps, you can go lower step by step (backwards)

Actually, I lied thinking about it.

I had it on auto at first, and that sets 1.15v. Few F9's then too cos I remember thinking "Oh FFS!" biggrin.gif

Booted fine after the initial F9 tho.

Things are a little confusing, no question about that. There are actually two BIOS choices on the official page, 0902, and 1002. 0902 is a "2T" memory BIOS, while 1002 is a 1T memory BIOS. Based on your memory, you may find that one works better than the other, though 1002 is a newer version.

Then, there are the "beta" BIOS versions on this thread. They come from Asus ROG, but are not official. 0079 was the initial version from the current set. 0081, 0082, and 0083 are the three that have evolved from 0079. 0081 is your 1T version, 0083 is the 2T version. 0082 I don't remember off the top of my head what benefit it has. Most have seen these BIOS versions to be a step up from the official, but some run into trouble due to the changes.

0902 is not a 2T BIOS of 1002, it is an older BIOS and does not have fixes that are in place in 1002

Look at my post again. 1002 is newer, but being a 1T BIOS, may not work as well for those who have 2T memory.

AMD Ryzen processors do not use pre-programmed VID tables.
1. Therefore, there is no fixed Vcore when the CPU runs in its out-of-box condition.
2. Default Vcore will vary depending on workload and will range from 1.2-1.3625V.
3. Overclocking an AMD Ryzen processor will snap the voltage to 1.3625V, but this value can be changed.

So above tells us it has no fixed VCORE.

Example, 1st R7 1700 at UEFI defaults ~1.089V measured on ProbeIt point with x264 loading CPU (3.2GHz ACB), 2nd same test ~1.119V, ~30mV difference. I did not do any measurements for 1st in UEFI and CPU is no longer with me redface.gif .

Now we know SMU control how VCORE is, The Stilt's thread states that. See the question I pose and answer here.

Now when we do a PState OC we don't change VID there, so IMO SMU is still controlling voltage, we just add an offset as required.
Quote:
So at stock let's say PState 0 is 1.089V with +0mV offset.

So if we read 1.228V on 3.7GHz OC - 0.01875V (offset required for OC) = PState 0 as 1.20925V.
So if we read 1.319V on 3.8GHz OC - 0.10625V (offset required for OC) = PState 0 as 1.21275V.
So if we read 1.409V on 3.9GHz OC - 0.19375V (offset required for OC) = PState 0 as 1.21525V.

Quote Link (above data is all LLC: [Auto] ie AMD stock).

Now above data doesn't even fit with PState 0 being 1.1875V either.

Now what did I see with say PState 2 meddling on UEFI 0902.



Now above shows 1550MHz 875mV, so lets say these values apply when in default UEFI mode, like we say PState 0 values are. But I don't get 1550MHz idle on defaults settings, so voltage is not going to be 0.875V at idle either. I measured something like 0.500V-0.600V in OS and a clock was shown of ~1.4GHz. When I start to just clock up PState 0 and not touch anything in Pstate 2 what happens?

Idle becomes closer to 1550MHz the more I OC above 3.0GHz frequency shown in PState 0. So what is happening is an automatic shift on lower PStates frequency as Pstate 0 is OC'd. The values in PState 2 becomes upper limit for that state.

Now lets go back to PState 0.





Now I see 3000MHz there as stock, this is base clock.

Warning: Spoiler! (Click to show)


Now that VID is ceiling for base clock IMO. So when in OS defaults 3.0GHz is not 1.1875V, SMU has determined what to do. Even 3.2GHz ACB is not 1.1875V, both my results highlighted above are way below that, 1st CPU ~1.089V, 2nd CPU ~1.119V (ProbeIt point).

I believe when we OC SMU is varying voltage, as shown in quoted data earlier with offsets added.

I believe when we are in UEFI and measure voltage CPU is not in lowest state or even PState 0 (ie 1.1875V) and the voltage we are reading is not relevant to use as to say plus an offset we will get x vcore. Again ref the linked post questioning The Stilt.

Is there a secret to installing ASUS AISuite???

I click the setup.exe, uac prompt pops up, I confirm, nothing happens, same with the AsusSetup.exe.

Other applications like Geekbench or RyzenMaster install just fine. AISuite does just nothing... ***

@gupsterg With the example I posted above (1.35v) adding 0.05v as offset gave me 1.4v under load which I needed for 4.0 GHz clock.

Do not dispute that smile.gif . I do not have all the answers wink.gif . Only sharing what I'm experiencing and collating smile.gif .

Do you have 2 "X" CPUs to hand?

On the right VCORE is 1.373V.

This is above 1.35V, so CPU is not at base clock in UEFI IMO.

I'm assuming screenshot is at UEFI defaults?
