Hello and hope someone has the secret! Let's have some fun!
I am trying to access the CPU multiplier settings in the BIOS of my HP Z620 workstation (it's basically like an X79 chipset but it's C602 for dual socket support) which are hidden. I have built computers my entire life..(exception of laptops/tablets)... I decided to take a shortcut this time because I got a good deal on an HP Z620 for a MAME project. It has an Intel XEON E5-1620 3.6Ghz quad core and came with 16GB and some other things.. anyway I wanted to see if the XEON was unlocked. The E5-16xx V2 (and pretty sure V3 also) are unlocked Xeons (undocumented but trust me they are, I have one) and this is the original E5-16xx "V1" series.. so I am VERY curious if it is also and I wouldn't mind a slight kick for free.
Before I get read the riot act (LMAO) I'm very familiar with overclocking/experienced and how this isn't an overclocking system blah blah it's really not a system I'm planning to push I basically just wanted to know if the CPU was unlocked and if it was I would probably raise the multi one notch and call it a day (just for the good feeling of getting more than I paid lol). It became a challenge as a looked and looked and couldn't find the trick (curses foiled again! lol).
Anyway, I THOUGHT THIS WOULD BE EASY... lol! I looked everywhere... nothing on the Z series so far.
Just to really break this down, here's what is going on. When I use F10 to enter the BIOS it's missing half of the normal things you would expect to see. I realize all vendor BIOS' are locked down but many of them give you SOME of the CPU settings.. this BIOS has NOTHING for the CPU except enable/disable HT... I know there must be hidden BIOS settings..(The BIOS is made by AMI)... or I need to flash a MOD BIOS to unlock the settings.
Don't call me nuts lol. This is not unheard of... there are actually many systems (many are HP) with special key combos to access hidden BIOS settings (https://www.youtube.com/watch?v=qSi0Xc4RcUc). The BIOS is made by AMI but it's just very limiting. I've read that some OTHER HP computers had special key combos to access hidden BIOS settings.
The ones I have found so far (but did not work for me):
* CTRL-F10 and then CTRL-F11
* F10 and then press A
Does anyone know of any other special key combos that might work or MOD BIOS'?
The following fix has been made in BIOS version 03.90:
- Fixes an issue where system would not boot when cards with large MMIO are installed.
The following enhancements have been made in BIOS version 03.90:
- This release improves security of UEFI code and variables and includes mitigation for the following vulnerabilities. HP strongly recommends promptly transitioning to these updated BIOS versions which supersede all previous releases.
Intel-TA DOC #548744
- Updates Legacy PXE OROM to 1.5.56.
- Adds F10 Setup option to Restrict USB Devices based on a variety of options including the ability to only allow keyboard and mouse.
- Adds F10 Setup option to disable error reporting if system has insufficient Option ROM space.
These utilities can be used to restore or update the System BIOS. System BIOS is independent of the operating system. To determine the BIOS family and BIOS date, press F10 on the target workstation during Power On to run the Computer Setup Utility, and then select File/"System Information". This information can be saved into a text file on a USB flash media device by selecting File/"Save to Removable Storage Device".
This SoftPaq includes the following methods for changing the BIOS version:
- Use HPQFlash to upgrade the BIOS directly in a Microsoft Windows environment.
- Use the utilities in this package to flash the BIOS in a DOS environment from bootable media.
- Use the ROM images in this package with the Computer Setup Utility (F10) to flash the BIOS from a USB flash drive or CD-ROM drive.
Thinking outside the box I like it however I'm not having any issues with keys not being recognized.. I can select F9, F10, F11, F12 and they all respond as well as the option messages and ESC boot menu it's just that when I get into the BIOS the only CPU option is to disable hyper-threading.. that's it.. Not even any memory settings.
I figure either there's a hidden BIOS with more options or I need a MOD BIOS...
