Unfortunately the 2570p uses and insyde BIOS, not an AMI. I only know how to enable multiplier overclocking on AMI. What he has done is a 4.8% BCLK overclock, which will work for all CPUs.

Maybe I can find where to raise the TDP by 10W, but that will require drudging through the BIOS decompressed into assembly.

His BIOS + ME FW:

2570OC.bin

Do the keyboard sequence:

WIN+left_arrow+right_arrow, then release on POST to enable the flash descriptor override.

Download FPT here:

fpt.zip

FPT needs to be run from DOS. There is a windows version but flashing in windows is very dangerous.

Backup your original ROM using FPT at the commandline in case you get a bad ME as discussed below and need to flash back:

fpt.exe -d origbios.bin

Flash the modified ME firmware with FPT using the command:

fpt -me -f 2570OC.bin

The file included is a full BIOS + ME FW image, but we are only flashing the ME FW. I could cut out the BIOS portion for a smaller download but this works. There is no danger in overwriting the ME FW with any other version, so flashing this mod properly is safe for any 2570p.

After flashing XTU may need to be reinstalled to enable the BLCK slider.

I do not know if this BCLK overclocking also overclocks the PCH PCI-E for eGPUs. It would be nice if someone could test PCI-E bandwidth in SANDRA with a BCLK overclock to verify if it does or not. If not I can provide an additional mod which definitely will overclock the PCH PCI-E.

UPDATE: New modified ME firmware file that works for Tech Inferno Fan, since this one didn't, is located here: http://forum.techinferno.com/hp-business-class-notebooks/2537-12-5-hp-elitebook-2570p-owners-lounge-41.html#post79212

How to check for a bad ME flash or XTU version

Below I've included an image showing what I check for a bad ME flash and/or bad XTU. A 'bad ME flash' in my case was Aikimox's modified ME contained in this post. I believe jot23 had this same issue.

I upgraded from XTU 3.2 -> 4.0 -> 4.2. All of them had the reference clock slider once I had flashed a good ME firmware with unlocked clocks c/o Khenglish.

Khenglish modified my system's own fpt.exe BIOS dump which resulted in a good ME flash. Now I can successfully adjust my BCLK. The captured XTU screenshot belowing showing a 4.63% overclock (2.7Ghz->2.825Ghz)

Can I use this on a 8470p? I recently installed a 3820qm on my 8470p and would like to be able to OC it a little bit and decrease voltage if possible.
