Intel 13th Gen Support?

veidas said:
9.5 works for me with Gigabyte B660M Gaming X and 13600k. I had to downgrade bios to the first version that supports 13th gen, dated 2022 August, and it started working. If I flash newer bios, it doesnt work. Seems like Intel introduced some undervolting lock later on.

Yes, correct. The new feature is called "Intel Undervolting Protection". It was silently released some time ago. Initially, it was intended to block undervolting using apps like ThrottleStop, but in practice, it can also break the BIOS undervolting. The options may still be in BIOS, but once you apply even a tiny undervolting, the system may become unstable, stop booting, or show a huge performance drop.

You may find more details here: Inter Undervolting Protection: The Whole Story.

So attaching screenshot per request to show undervolt working fine using Throttlestop 9.5 with Gigabyte B660 board and 13600k. Still playing around trying to see if its stable, but the results are ridiculously good. It used to need 180w for full performance, and with huge AK620 cooler I would hit around 90c on cinebench r23. Now it uses around 130w and doesnt go above 68c. So 50w less on full load and over 20c cooler. For anyone having trouble undervolting with B660, I suggest to downgrade bios to the earliest version that supports 13th gen CPUs. It should allow Throttlestop to work. Cant test overclocking, since its a B660 board, but I would imagine it should work with Z series board.

It looks like the early microcode 05 allows voltage control on 13th Gen CPUs. Thanks for posting that info.

It also has a lower stock vid than 10E just fyi

Yes, even on stock settings, my 13600k uses ~10w less on full load and runs cooler with earlier bios version. Why would they increase it later, if it can run on much less
 
In terms of undervolting, things are more complicated: Intel Blocks Undervolting: The Whole Story.

It is possible to undervolt 12th and 13th gen SKUs through ThrottleStop if the following conditions are met:
- Intel Undervolting Protection is disabled in BIOS
- The motherboard vendor implemented this option properly and fixed all related issues, OR the motherboard is using an old version of BIOS

It is possible to undervolt through BIOS as well, but:
- There should be this option available
- All the issues with Inter Undervolting Protection were fixed. At this point, the common issues are: a huge performance drop after applying a small negative offset through BIOS, issues with booting the device, and some kind of throttling (like IA CEP)

Sounds like Intel is living in fear of low voltage. Set it to the moon, just to be safe. Multiply that by millions of computers worldwide and that adds up to a lot of wasted energy and excess heat.

No, that post is correct. If a motherboard or a laptop vendor decides to enable the new Intel Undervolt Protection feature and does not add this setting to BIOS, the undervolting will be completely blocked.

Also, this new feature may break the undervolting on some motherboards event if a vendor decides to keep it enabled. There're some motherboards where these issues were fixed, but it's a lottery.

I see ThrottleStop hasn't been updated since June '22. I found this tool a few years ago when I had a 8th gen Intel CPU and I've really loved using it to set my Clock ratios and Speedstep settings, etc..
I just recently upgraded to an i7-13700K and notice it doesn't seem to support 13th gen chips. It seems to have partial support but some features are just broken and setting ratios doesn't seem to do anything for the Efficiency Cores.

Has there been any update on when 13th Gen support will be added?

I found solution to undervolting issues with 13gen (13700k) on ASUS TUF Plus D4
BIOS updates or previous versions will change nothing.


After installing latest INTEL® MANAGEMENT ENGINE Firmware Update
(Find appropriate to your Motherboard BIOS - I.M.E. is installed from Windows):

... undervolting has began to change voltages on CPU,
... SVID ("Best Case Scenario") lowered voltages automatically to lowest and STABLE levels.


Mine 13700k goes 5,5GHz at 1.3V (225W) ..... before 5,4 at 1,45V (270W)

But can you actually adjust voltages with Throttlestop? Thats what this topic is about..And are you using B series motherboard?

New versions of bios (desktops) contain Undervolting protection option: disabled/ enabled.
I have TUF PLUS Z690 D4 WiFi.
Bios ver 2204 (Newest)

After installing NEWEST INTEL® MANAGEMENT ENGINE Firmware Update.
Bios changes AFFECT the voltages,
It worked for me.

1,45V > 1,3V stable! 13700K

Try to find latest INTEL® MANAGEMENT ENGINE Firmware Update.
for your motherboard
and install it (from windows).
This may enable Throttlestop change voltages.
Worked with my bios / throttle stop under windows

I have the latest. Only thing that allowed me to undervolt was using old bios version that came without intel dynamic undervolting block.
 
Hello there,

I have an MSI Titan GT77HX V13 (4090 and 13980HX)

My BIOS shows Undervolting Protection and I can disable it.

I have to go through a lot of hurdles to be able to OC P-Cores but I can't OC E-Cores. Every time I click on E-Cores it doesn't let me it's like it's greyed out.

Any ideas what it could be?
 
I can confirm that new beta version is working on MSI Titan GT77HX V13 with 13980HX and 4090. All unlocked, but I think changing power is the only thing that doesn't work where I set it to 300W but max only takes 200W.

Post a TPL screenshot. Many laptops will enforce a lower power limit. Make sure the MMIO Lock box is checked.

I will try again with that box checked

Sadly that's not happy there. I tried changing things in the BIOS in Power / Performance section but it's not taking
 
Hello Unclewebb!First off,thank you for all that you do,can you please send me the beta link for 13th gen mobile support also?I have a Legion 7i Pro 13900HX with advanced bios and I can disable undervolt protection and I should be able to change most of the settings.Thanks!
 
Greetings, Unclewebb.

I was wondering if I could receive the link to the new Beta as well? I have obtained a 13980HX and I'd prefer to use software that is more safe and intuitive than XTU.

Thank you.
 
Hey uncleweb, 13900kf user here been using the 9.5 for some time and it worked well. Can i also recieve the link the new beta as well for testing purposes? Thanks much
 
Hello there,

Can confirm that ThrottleStop 9.5 is working with old BIOS.
My setup:
  • Intel i7-13700KF
  • NZXT Kraken Z73
  • Gigabyte B660 AORUS MASTER DDR4 rev 1.3
  • BIOS F8 (August, 22)
  • Offset voltage -0.160mV
  • Cinebench R23 result ~29500 points
  • Max power ~190W and max package temp ~75C

so far it’s working great.

Well tinker with downvolting at a later time.
