This board only has Offset Mode Voltage in BIOS



Is it possible to know if there's some sort of hidden setting to have fixed voltage instead?
And if Turbo Boost can be also disabled?

bump

just want to know if this is possible

@aiocr - Yes, there is a setting hidden from you that controls if CPU voltage is >> Auto, Fixed, or Offset
I can make this visible to you if you want? And yes, same on turbo, there is a turbo boost setting to enable/disable too. If you want these made visible to you, please give me images of the section you are in above, from top to bottom so I can see everything visible to you in that section.
Please try F12 to screenshot to USB, if it does not work, then use camera and resize images to 800-1000 px wide, then put all images in a zip and upload for me, thanks.

@Lost_N_BIOS





In the "Turbo Boost" option when i click nothing happens, no prompt, etc. It's like a "greyed out" setting.

I'd definitely appreciate if you did that, just one question though. Is there any risk in "bricking" the motherboard by modding such settings? I don't understand much about the subject and as this is the only PC i have i just want to be safe. Hope you understand. Ty

don't worry @Lost_N_BIOS i know you have been busy

@aiocr - Only real risk is if you have a bad flash, this is easy edit, nothing to go wrong or risky here.
What CPU are you using?? And I assume you want 2.20 BIOS edited, correct?

Which "Turbo" are you specifically talking about, that "Does nothing"??
Here's how those (Asrock Specific ones) work on this BIOS
https://forums.tomshardware.com/threads/...tuning.1768017/
https://www.anandtech.com/show/6089/asro...cy-bites-back/3

Intel Turbo will enable or disable Turbo, no way that does not work, unless maybe your ME FW is messed up?
Can you change CPU multiplier and or memory speeds? If yes, ME FW probably OK, and especially more-so probably OK if you can see ME FW version w/ HWINFO64 as shown below

So, as of now, this is the requested edit you need, correct?
CPU Voltage >> Auto, Offset << Hide
CPU Voltage >> Auto, Fixed, Offset << Make visible

+ I will also make visible >>
DRAM Config Mode >> Performance, Compatibility Mode (hidden from you now)

Which "Load Line Calibration" can you see? Do you see 100%, 50%, 0%, OR Level 1-5? I can switch if you want the one with more options. OR, do you want me to leave this as it is now?

So, edit 2.10 BIOS then? I can put any microcode you want into 2.20, if you want new BIOS without spectre/meltdown microcodes, or I can just edit 2.10, up to you?
But, unless you disable Windows (10 I assume) from loading it's own latest microcode, then what's in the BIOS does not matter at all and windows will load it's own and BIOS one will not be used
Here's how to do that in post #272

Turbo is for use w/ stock speeds, ie CPU running at stock 3.4Ghz and then this applies when you enable Turbo you mentioned (w/ the other one disabled, not on auto)
Maximum turbo frequency 3800 MHz (1 or 2 cores)
3700 MHz (3 cores)
3600 MHz (4 cores)

Since you want to OC much past stock speed, and Intel Turbo stock limits, you should disable Turbo as it's no use to you w/ an overclock and unlocked CPU anyway.
You should be able to disable both "Turbo" features, and then manually set whatever CPU multiplier you want.

You said changes I mentioned + Turbo made visible, yet you can already see turbo and commented it's not working.... So what do you mean make it visible, it's there already?
Disable this, you are overclocking anyway, so useless. Unless, Asrock has something configured to where you can't OC CPU Multi without it enabled, if that is the case then leave enabled and set your 45 multi for CPU ratio
Some systems, to use Turbo, C3 or C6 has to be enabled, I forget which and or if this is a thing on Asrock and or Z77. But, it should be no problem to run at 4.5Ghz always, since you have unlocked CPU (Disable speedstep, C1E, and EIST first)

On LLC, so you want to try the one with 1-5 level? OK, will do Either way, you can tell which is giving you more/less under load, but keep an eye on idle amount too as that's affected sometimes as well.
To see which gives you more/less under load, set 0, 50, or 100 and test CPU under load using CPU-z benchmark tab with a second CPU-z open, or other voltage monitor, so you can watch idle/load voltages, then you'lll easily see which gives what you want.

Leaving some more info.

About microcode:

I remember few years back messing around with UBU tool and seeing a microcode recommendation. I took a look and still had that version on my HDD. In newer versions this recommendation cannot be seen anymore as the procedure/menus have changed a bit since then.



Version 19 was listed as "best overclocking" so maybe go with that?! Currently running 2.10 BIOS with version 12.




So, in short, the "To-do" list would be:

Edit BIOS 2.20 to have microcode Version 19 instead of the most recent one with spectre/meltdown fixes;
CPU Voltage >> Auto, Offset -- Make option "Fixed" visible;
Intel Turbo Boost Technology -- Make this option interactable, currently i cannot disable this, as "Disabled" isn't reachable as explained before;
DRAM Config Mode >> Performance, Compatibility Mode -- Make this visible;
Load Line Calibration -- Switch to Levels instead (Level 1-5)

As always, open to any recommendation you might have on the matter. :)

@aiocr - Yes, I can put in whatever microcode you want
2.10 BIOS has (for 3570K/906A9) >> Rev 12 4/12/2012
2.20 BIOS has Rev 1F 2/7/2018 (post Spectre/Meltdown)

Latest actual microcode that is non-spectre/meltdown = cpu306A9_plat12_ver0000001C_2015-02-26_PRD_2F737D45.bin

Intel Turbo Boost tech setting should let you enable/disable, but it's possible that the Asrock 30 Turbo at top is stopping you, if you have that on auto or enabled etc.
Or, this may be a BIOS bug with version 2.10? I suggest you test with 2.20 now and forget about microcodes for a second until we're done

Or, you may need to load optimized defaults, save/apply and reboot back to BIOS, do not touch anything else, except disable Intel Turbo, then save/apply and reboot back to BIOS to make rest of your changes
Some BIOS (brands) require you to have C3 or C6 or C1E enabled to even use turbo, so having those disabled may also be what's causing you to not be able to change it? Hard to say without having the board here myself to check it out.
On this, before we do anything else here, please do as I mentioned above with Optimized, and let me know what happens. Then, it still same, I will send you BIOS with edit to this setting only to see if Nulling the suppress and gray out if constraints on this then allow you to change it.

It's greyed out if by the two following things = True >>
QuestionId: 0x2D equals value 0x1 {12 86 2D 00 01 00} >> Which = >> Offset voltage = -0.005V, Value (8 bit): 0x1 (Which to me, seems like this would be a bug, no reasoning for this to be a thing)
QuestionId: 0x41A equals value 0x1 {12 06 1A 04 01 00} >> Which = >> CPU Ratio = All Core, Value (8 bit): 0x1 << So, due to this, please set CPU Ratio to Auto (which should be default after you do above), then test again.

And suppressed if the following = True (in which case, you should not see the setting)
QuestionId: 0x3 equals value 0x0 {12 86 03 00 00 00} = Intel SpeedStep Technology = Disabled
QuestionId: 0x41A equals value 0x0 {12 06 1A 04 00 00} >> CPU Ratio = Auto
QuestionId: 0x3D equals value 0x0 {12 06 3D 00 00 00} = Limit CPUID Maximum = Disabled

So, if any of the above = True, Intel Turbo should be hidden from you, and or may be grayed out etc.
I'll Null ALL of this in test BIOS for you if we can't sort via optimized testing mentioned above

Turbo voltage would not need disabled, auto or a voltage increase would be all you'd need, if you wanted to use this. I checked, and that is all this contains, Auto + Voltages
Voltage applied here would not affect enable or disable of turbo.

Yeah, we'll make you a BIOS with manual voltages first + 1-5 LLC and one with 0%, 50%, 100%, then you can test like that and see which you like better
That UBU info on microcode may be outdated, about which is "Best for Overclocking", but I did check for you on the latest version that is like that (old style 1.69.17) and it still says same ver 19 (6/13/2013) is best for OC.
But again, that may be dated info?

I'd suggest using 1C from 2015 for best stability and likely same OC as 19 too, you never know unless you test and tweak and test and tweak while comparing both on your exact system with your own personal tweaking skills.
But it's your system, so yes, up to you!

OK for now, we'll go with 2.20 + Rev 19 microcode + >>
CPU Voltage >> Auto, Offset -- Make option "Fixed" visible;
Intel Turbo Boost Technology -- Make this option interactable
DRAM Config Mode >> Performance, Compatibility Mode -- Make this visible;
Load Line Calibration -- Switch to Levels instead (Level 1-5)

@Lost_N_BIOS

A lot of useful info, ty!

And you were absolutely right, i did some tests as you suggested (on 2.10 but i remember that on newest version the behavior was the same):

Loaded "optimized defaults" rebooted and Turbo became interactable > can select "Disabled";
As soon as i set "CPU Ratio" from "Auto" to "All Core" Turbo Boost becomes "Greyed out" again;
If instead of "All Core" i select "Per Core" Turbo becomes interactable once again > can select "Disabled";
And here's a weird thing though, if after that, i select "All Core" again, Turbo Boost is still interactable > can select "Disabled";

Anyway, i guess we're good in this front after all, Turbo is apparently reachable to change, so off the list it goes. TIL

About the microcode, i thought about that and you're probably right, info is most likely outdated. I'll take your suggestion and pick the 1C which seems to be the best choice as you explained.

Would then go like this:

BIOS 2.20 + 1C microcode + >>
CPU Voltage >> Auto, Offset -- Make option "Fixed" visible;
DRAM Config Mode >> Performance, Compatibility Mode -- Make this visible;
Load Line Calibration -- Switch to Levels instead (Level 1-5)

@aiocr - Nice to see Turbo is sorted and figured out now!! Yes, that is a bit funky how they have it set up, poor decisions/implementation by BIOS engineers?
I guess they want to keep in line with "Intel Spec" since you can't "All core" Turbo to max multi, so it's kinda trying to tell you no by doing it that way, but it's not ideal without explaining that to user upon hover/select of these settings

I can (will) null all that suppres/grey if on Turbo, but the actual application of how it all works (or not) will still be same.
Meaning you can't all core turbo, but you would be able to change this setting no matter what, whenever you wanted (invalid selection would be ignored and or changed on reboot possibly)

OK then, I will make you mod BIOS per outline above now I'll make you two BIOS, one with 19 and one with 1C, then you can compare

* Edit - @aiocr - Here, please test and let me know if all is as it should be menu-wise, then if so you can go ahead and test 1C vs 19
If it's not all proper menu-wise, let me know what's wrong/missing etc.
