Vcore with 7940X and Asus Rampage VI Apex

[tistou77]

Hello

It seems that Aida64 reads the VCCIN (CPU VRM) and not the Vcore for the 7940X (maybe with 7920X, etc...)
It is missing the voltages for the "CPU VRM" and "Cache CPU"

 

 

 

Thanks

Please right-click on the bottom status bar of AIDA64 main window --> Sensor Debug --> ISA Sensor Dump. Copy-paste the full results into this topic, or attach the results as a TXT file to your post. You may need to enable status bar in AIDA64 / main menu / View first.

Thanks,

Thank you.  Please upgrade to the latest beta version of AIDA64 Extreme available at:

https://www.aida64.com/downloads/latesta64xebeta

After upgrading to this new version, make sure to restart Windows to finalize the upgrade.

Let me know how it works.

Then the Vcore is indicated but remains "blocked" in idle (no variation in load)
The CPU VRM and CPU Cache voltages are not indicated

The way it works on your motherboard is that at idle the Vcore voltage provided by the onboard sensor chip gets too low.  In which case we've been told to use the CPU VID value instead of the measured Vcore voltage value.

As far as I can tell, the voltage rails you miss aren't monitored by the onboard sensor chip on your motherboard.  You may be able to adjust those rails in the BIOS Setup, but readback is not provided.

Ok thank you, and you know if on the Rampage VI Extreme, it's the same ?

AFAIK it's the same there too.

[tistou77]

Ok Thanks

Something I do not understand, with the Turbo Vcore software from Asus, it's possible to have the voltage of the Mesh/Cache (and modify it), Aida64 should be able to read this voltage, right?

And with the old beta, CPUID read the VCCIN instead of Vcore, is that this tension was accessible ?

Thanks

[tistou77]

Hello

With SIV 64X, the voltages of the Mesh (VCache) and the VCCIN are well indicated
Just the VCCIN (CPU VRM) which is indicated as "Vcore", a bug to regulated the side of SIV

 

Thanks

Hello Fiery

If you need other tests, to have these voltages with Aida64

Thanks

[Fiery]

All I can tell you about the Vcore issue is that AIDA64 does what the BIOS does on your motherboard.  If the logic behind it seems odd, well, then the BIOS works odd too

We've added the requested CPU Cache voltage reading in the latest beta version of AIDA64 Extreme available at:

https://www.aida64.com/downloads/latesta64xebeta

After upgrading to this new version, make sure to restart Windows to finalize the upgrade.

Ok for Vcore, no worries

It seems to be good for Cache voltage
And for the voltage "CPU VRM", it should be possible to have it?
CPUID Aida64 reads it (but it is indicated Core Voltage and not CPU VRM)

Or it is a misreading of the Vcore (even if the voltage corresponds to the VRM CPU) ?

Thanks so much

PS: It also lacks + 3.3v voltage, normal ?

AIDA64 CPUID Panel shows Vcore, matching the "CPU Core" voltage reading on the Computer / Sensor page.  There's no separate CPU VRM voltage rail that one could measure on your motherboard AFAIK.  We'll add +3.3V readout in the next AIDA64 beta update due in a few days from now

Thanks for the +3.3v

For the CPU VRM (VCCIN), this voltage is very well read by SIV 64X (indicated in yellow on the screen)
There will be an update of SIV to indicate the VCCIN (instead of Core)

[Fiery]

VIN0 line holds VCore, not VCCIN.

[tistou77]

that's why SIV will do an update normally, and indicated this voltage as VCCIN and indicated the "good" tension for the Vcore
Several people with Rampage VI have tried by changing this voltage in the bios, and this is the VCCIN

Or this tension is available or we do not understand

All I know is that VIN0 is Vcore But at idle its value shouldn't be used.

ok thanks, I will use SIV64X to be able to read the VCCIN, in idle and load, the voltage is correctly read (checked with the DMM on the motherboard)

I also asked Asus to see if the problem could be corrected
For other brands of motherboard, is it the same or not ?

We've done more research on this.  As it turns out, on Asus Rampage VI Apex and Extreme boards VIN0 holds VCCIN when you have a Skylake-X processor installed; but the same register holds the Vcore when you have a Kaby Lake-X processor installed.  Similar separation of register layout, based on the type of installed processor exists with other manufacturers as well.  It's a recent phenomenon about the X299 platform, and should be no longer an issue once Intel commits to a single CPU architecture for each platform

We'll correct the VCCIN vs. Vcore issue in the next AIDA64 beta update.

Ok, thanks for the explanation
Will it be possible to read the VCCIN with a Skylake-X and the next update on a Rampage VI ?

Thanks so much

Yes, of course. On Rampage VI boards with a Skylake-X processor installed, VCCIN will be measured, and Vcore will show the same reading as CPU VID.

[tistou77]

Ok thanks so much

Hello

With X299, the CPU Input Voltage is indicated VCCIN, and on X99, it is indicated CPU VRM
It is possible that also was indicated CPU VRM on X299 ?

Intel uses VCCIN for the Skylake-X voltage rail in question, so that's the correct term to use by monitoring software as well.
