[REQUEST] Dell Optiplex 790 BIOS Unlock
#1
Hi, guys! Sorry for my bad english.

My name is Alexander. A month and a half fighting with the BIOS. I need to access the BIOS settings. Hackintosh. I want to do without the patch MSR. The IFR saw the item on / off MSR lock. And also change the graphics settings. Please help me. He failed 5 times already addressed in SC for flashing on the programmer after the experiments. Both NVRAM changed, and AMIBCP, and the SetupPrep module. In the IFR dump everything changes. After the firmware does not pass POST. Apparently sitting somewhere a Checksum validation. In one word-I in despair. Would be finances, I'd buy another PC. But, I live in DPR, Ukraine or Russia - it is unclear. Financial position have us the sad(. So option one is to defeat Dell. Thank you in advance for your attention and time.

Link for BIOS

https://downloads.dell.com/FOLDER0482163...90-A21.exe

P.S.
AMI Utilities not work. AMISCE,Afudos and other. EFI utilities for editing Efi Vars - not work.

Hi all,

I have a Dell Optiplex 790, and have installed a Intel i5-2500k and looking to overclock it, but the feature is locked down by Dell Sad

Would it be possible for any of you Bios geniuses out there to unlock any hidden or locked options from the attached latest A22 bios for my machine please ?

I have also tried Throttlestop and XTU from Intel to no avail

Throttlestop cant increase the multiplier past the stock x37 which is annoying as I know the 2500k is capable of much more.

Thanks in advance, but not holding out much hope, as I believe Dell lock down the Bios protection too Sad


Attached Files
.rar   O790-A22.rar (Size: 5.34 MB / Downloads: 39)

you need to remove BIOS chip and flash new BIOS with SPI flash tool, Intel ME locks BIOS down otherwise.

Hi everyone,

This is my first PC, which I built a few months ago:

Dell OPTIPLEX 790 Desktop

Motherboard: Dell 0J3C2F

CPU: i7-2600k

GPU: GT 1030

RAM: 8GB DDR3

SSD: 500gb

I want to overclock my processor but of course Dell's locked bios has no options to overclock. My BIOS version is A22 03/07/18

I was wondering if anyone could help me overclock my i7 2600k, whether that means a modded BIOS or whatever. I have attached my current bios.


Thanks in advance,
Jacob.

Would it be possible to unlock the debug menu on this BIOS, as well as enabling overclocking options and XTU?
