Souping Up a Lenovo M93P Tiny for 4K

it should definitely lower them, I ended up moving the 4790s into my dell 9020 usff and putting an i5 4670(84w tdp!) with the same settings and it seems to obey the limit
just make sure you completely remove intel xtu and reboot before installing throttlestop(if you already have throttlestop installed, consider reinstalling from scratch)

I found throttlestop seemed to only work properly after intel xtu was completely removed from the system
always use hwinfo to confirm voltage offsets too, should show whether throttlestop is working or not
I use occt to confirm power usage(will flatline with a package power usage of 52w)

I've also joined the forum just because this seems to be the only real place that I can find these Chinese conversion chips being discussed. Hopefully you guys that have messed with them can help a bit. I have a M73 Tiny and I bought one of the Magic Reform i7-4870HQ. I saw that earlier posts mentioned this working for someone else. I'm running the latest version 85 BIOS for my Thinkcentre. When I install the i7, it shows up correctly in the BIOS and is identified. The only issue that I can find is that it gives an error that there is no microcode update available. Did anyone else that tested one of these chips run into that? Anyway, when I try to boot an SSD with Windows, the system hangs on the black Lenovo splash screen. If I try to boot from a Windows 10 installer USB, it will boot to the Windows Splash screen with the loading dots, but never goes any further. Makes it seem like something is wrong. However if I boot to an Ubuntu Live USB, everything boots normally and I can use the system. I'm really not sure what's going on. I swapped back to the original i5 chip and Windows boots normally. Does anyone have any ideas? Do you think that I just ended up with a bad i7 CPU? Really strange considering that it will boot to Linux. I'm wondering if there is some BIOS setting or version that I'm not aware of. I am using a 90 watt PSU btw.

I have the same issue with my M73 Tiny and i7-4950HQ. Looks like no microcode updates are included with the built-in bios. I was researching to include the microcode for CPUID 40661 within the bios update, and it is possible with either UBU tool or MMtool Aptio 5.0.0.7. A microcode bin file has to be downloaded and then injected to bios update. The further step is SPI programming since bios protection has to be overridden, but there are two chips on the motherboard: one with 8mb storage and another with 4mb storage capacity. The original bios has to be backed up from both of these chips and then the modified bios with updated microcode has to be split in two parts identical to the ones backed up by SPI programmer. After splitting modified bios you will have to write it back onto those two chips.

It is a theory, but I do have the modified bios version 85 with patched microcode 40661 for i7-4xxxHQ CPUs.

Now waiting for a SPI programmer to arrive to start experimenting.

Strange thing is that I can easily boot into Windows / Linux / Hackintosh, but I do get the same beeping warning about missing processor microcode update… and that is the thing I want to get rid off.

Please, give a feedback, if you were successful with modifying the bios to support 40661 CPUID’s microcode😉
