1.557v ASUS - ROG STRIX Z790-E GAMING WIFI new bios(High Voltage Concern)

ManCaveMike
Level 10

My motherboard is the ASUS - ROG STRIX Z790-E GAMING WIFI (Socket LGA 1700) Intel Z790 ATX DDR5 Wi-Fi 6E Motherboard  and everything is at stock value except I am DRAM Frequency set to 6000mhz for my ram.

 

CPU is 14900K with Corsair H150i Elite LCD XT

 

R23 score was 33k

Does my Voltage look normal?

All right, very good.

Yeah there are different settings for the SVID Behavior, I'm not sure what they all actually do, but I usually set mine to Best Case Scenario and adjust the LLC setting if needed.

The end goal is to have the maximum Vcore showing what you're setting in the bios. So, I'm setting 1.45v and my maximum Vcore shows 1.447v, this is close enough for me. You could try the Best Case Scenario setting and see how the CPU VID voltage reacts.

 

 

 

Ill give that a try.

Intel  failsafe made everything in the 1.4 and temps high.  Typical cripled performance.    I cant find any pictures of what  some of these settings are for my mobo and since I have no experience with it, I dont wanna touch it, but I know where the svid is, so I will try that,  Not sure what LLC you refer to

spiked over 1.5 again and now throttling

starting to wonder if I just got a bad cpu

Those temps are fairly high for 253W. Nothing wrong with the CPU, your cooling is the limiting factor.

Check mount, and then as the first user suggested, set SVID Behaviour to Typical. The simplest method to preserve performance in Cinebench is to disable CEP.

 

9800X3D / 6400 CAS 28 / ROG X870 Crosshair / TUF RTX 4090

Typical murdered performance almost as much as best case did.

Turning CEP off caused black screen on opening OCCT so I didnt even try to run it.  I got too scared.

These temps above are with IA VR 1423.  Im gonna power down and remount my AIO

Cooler currently has 164 to 178 in points depending on bios settings

Your CPU probably isn't likely able to use Best Case.

1. Remount the AIO, and check for consistent mounting pressure.

2. Clear CMOS

3. Set SVID Behaviour Typical

4. Disable CEP

5. Retest

The VID is preprogrammed at factory by Intel, and differs depending on the strength of the silicon. i.e., some chips will have higher operating voltage at stock than others - not all CPUs will respond the same way to manipulating SVID Behaviour (ACLL). For the record, SP98 isn't bad. Retest after conducting the above.

9800X3D / 6400 CAS 28 / ROG X870 Crosshair / TUF RTX 4090

Ok

 

I remounted my H150i Elite LCD XT.  I removed all existing thermal paste from both cpu and the aio, using a paper towl and isopropyl alcohol 99 percent

 

I reapplied MX 4.  I studied the area that had the least amount of paste, the top right, and when I applied I did the spread butter method with a mini pea size in the middle just for added paste,

I then cleared my Cmos.

Bios set as follows.

SVID to Typlical
Disable CEP
DRAM Frequency 6000

Retest with OCCT(testing R23 next)

For the first time since I owned my CPU, I am in the middle on all sections.  Ill report back when I run R23.  I am also running at 5,7ghz instead of the 5.5 it was prefering.

Thank you and thank you to Nate for all your help.

 

Here is my HWinfo 

 

ManCaveMike_0-1733733679890.png

And here is my new 35k score in R23

ManCaveMike_1-1733733709743.png

33k score was my default settings and caused thermal throttling.

35k is the new score and lower temps and voltage!

 

I am going to leave the settings like this and will test some games tomorrow(tonight)  Thanks again.,

Best Case scenario has the worst R23 score I ever seen in the last several years.  It cut my score in half!

 

Still hits 5.5 and vcore dropped.  Ill have to see how it is in games now,

Best Case is also cripling gaming performance.  Losing 60 to 100 fps, massive dips and stuttering.  But voltage looked nice.  Just gonna go back to 1423 on the ia vr
