OK, now I see why you mentioned P6T. Yes, mainstream brand boards can have a lot of options, OEM/no-name boards usually are very limited.

You can only set the highest multiplier locked to the CPU by Intel, in your case that is 23 (25 or 26 max turbo multi, early BIOS may only allow that when single core is used/under load) - http://www.cpu-world.com/CPUs/Xeon/Intel...0614X5675).html
Sometimes, after 1366 was out for a while, all motherboards had updates that allowed setting max turbo boost multi as the main/only multiplier, your BIOS does not have this update applied to it and it's not a setting or something modders can apply, this is something the BIOS engineer had to do way back then.

Did you ever adjust the Performance/Watt select setting directly under TurboMode Tech setting, that affects how Turbo mode is applied, always or only after certain time period then it kicks in

Here is BIOS with updated microcode for your CPU only (not latest version, but 2015). This may not help, but worth trying. I know if original was 2009-2010 then maybe better chance this could fix something, but still worth trying anyway

Hi mate, just coming here to really thank you for helping with this, after much failure in this I found a bios with the turbo working, I just flashed and it's work but just in some core's, the multiplier only reach x25 but is a improviment anyway.
If someone need it here the bios I used (Koloe x58 5520/ich9r) --> 116.6.104.5:801/yks/s/49d979df
A dude from a russian forum asked a seller for a bios with TW working and the seller gave this BIOS.

@Hungary137 - Great you found a good BIOS, please upload for me so I can put in folder, in case someone needs later. It's normal, not all cores can reach max turbo
I can't download from that link, it just takes me to google results with two results (one in 2016 and one in 2018), neither of which I can download from either
I was able to get to a webpage in FF finally, but I see only one BIOS >> GBL58501 X58 BIOS.ROM and not sure that's the one you are using? Please upload the file you have so I can compare

I uploaded here, is the same archive. "GBL58501 X58 BIOS.ROM"

Sorry to interrupt, maybe someone is willing to help me...
i'm trying to replace the boot logo by an all black one.
it's a Supermicro X8SIL-F on bios 1.2a (latest, can be downloaded from the site here: https://www.supermicro.com/products/moth...8SIL.cfm?IPMI=Y
thanks a lot!!

@basco - This is not UEFI BIOS, that is why you cannot open with UEFITool. I assume that is why you posted a reply here?
This is an example file, do not use this for anything, but I need to ask if this is the correct logo you want to replace with all black? Do you want the text removed from bottom too (Press Del/Tab)?


* Edit - I assumed the above was the one you wanted replaced


x8sil2mnt = No Text (complete black)
x8sil2mt = Text only at bottom (press Del or Tab info)
Both BIOS have updated CPU microcodes, from a previous edit I did for someone else (all updated except CPUID 106E0)
http://s000.tinyupload.com/index.php?fil...819834777149254

W o w !!

Yes, i would like a complete black screen without text.
If i understand correctly, you also updated the cpu microcodes in my bios? what advantages do i get from that?
And what does CPUID 106E0 mean? And why shouldn't that be updated as well?
I will flash your modified bios tomorrow and let you know.

Thanks!!

@basco - 106E0 is for ES (engineer sample) CPU, general public usually doesn't use these, so the updated microcode is tough to find, and I've not found latest one as of right now, so that is why it's not updated
I didn't notice until now, that the old edit I did for other user to update the microcodes, I didn't use latest 106E5, so here is new set, this time with all updated to latest for sure except 106E0


http://s000.tinyupload.com/index.php?fil...554665407594580

CPU microcode updates have latest bug and errata fixes, security fixes etc from Intel. Sometimes manufacturer updates these when they put out BIOS update, but often they're too lazy to do unless it's big security fix, and you know BIOS update slow to never on some too.
If you end up wanting the Logo edit without the microcodes updated, let me know and I will redo for you. For complete black without text you want >> x8sil2mnt.bin

I've been searching this forum, does this post contain 106E0 and it's successors?? Or is this something completely different...
Intel, AMD, VIA & Freescale CPU Microcode Repositories Discussion (3)

i flashed it, it works!!
Is it possible to quiet the PXE boot rom messages also? (while still having a functional PXE boot of course)

@basco - I'm not sure what you are asking about 106E0 above?? Did you mean on that page, is there a newer 106E0? If that is what you meant, no, those are same version your BIOS currently has (Old - FFFF001F)
I'm not able to find the latest 106E0, it's only necessary if you have a CPU with that actual CPUID anyway, and wanted latest for it.

Thanks for quick report back, and great to hear BIOS works as you'd hoped!

On the PXE thing, what happens if you at Advanced >> Boot Feature >> Quiet Boot (set enabled, or disabled) - Does the PXE messages still show either way this setting is set?
Other than that, I see no way to disable this message. Show me what you see on this, I may be able to remove the text and leave just blank screen, but for that I would advise you have a programmer in hand and backup made in case edit causing BIOS to lock up at that module with no way past it if it's a bad mod.

FYI to anyone looking later, this BIOS has headless option (may be visible, or hidden, unsure, but could be made visible if hidden)

I can set headless mode in this bios. it's under 'acpi configuration'.

I mainly mentioned because I'm asked about this from time to time on various BIOS, and I rarely see it as a BIOS option, so I dropped that comment here for anyone looking for a board that has this option later on.
Thanks for confirming the setting is visible by default.

this is my pxe boot screen:


haven't got a big wallet, but made a donation. thanks!

@basco - Thanks, the site appreciates your donation!

on the PXE screen, I don't think I could edit that to be blank, or it would mess up the PXE module function, however, I see here in a random config PDF that this screen may be hidden sometimes by splash logo https://cs.uwaterloo.ca/~brecht/servers/...agnt/config.htm
So, maybe that setting I mention on post #25 would hide it, did you test both ways (Quiet Boot)?

Also on that same page >> AddOn Rom Display mode >> Try that "Keep Current" or "Force BIOS"

* Edit - I also see on that link above, in the actual PXE function once you enter it, you can hide this option via >>> Show Setup Prompt << Disable and or set timer to zero

ok,
tried quiet boot (both enable and disable), did not hide pxe
AddOn Rom Display mode both ways did nothing.
i cannot open the pxe setup menu, CTRL-S is not working... do you think this can be fixed?

i've found bootutil.exe from intel, but cannot reflash so far...

tried ibacfg.exe, it says 'no supported adapters found'
