I misread nearly all characters in the first place ~0.5 mm text height is adveturous reading. Panet3dNow made a very clear picture of the chip I already posted a link to their webpage. 9LPRS471 and 9LPRS478 where clock generator chips for the 690G chipset. Googling for 9LPRS478 shows a link to the IDT page where you can download a datasheet. Fortunately I have such a board here. i2cdetect -l shows the PIIX4 adapter i2cdetect 0 shows there is someting at 0x50,0x51 and 0x69 none of those adddresses can be dumped. I Tried each one after a cold start, because as you expected this was required on the sapphire board to get the dump work again. I also have an Gigabyte 780G board and an Asus M3A board (770 chipset) here. ? The gigabyte has an 9LPRS477CKL chip and the M3A uses also the 9LPRS477BKL. 780G ?i2cdetect -l shows the PIIX4 adapter i2cdetect 0 shows there is someting at 0x50,0x51,0x52,0x53, 0x38,0x69 I attached the dumps of 0x38 and 0x69 to that mail. > > Both chips have an SMBus interface so most certainly at least one of > the addresses of i2cdetect corresponds to this chip.

Same here but this chips is also very hard to read and the numbers might be similar looking characters like those i noted. BTW: Both DFI Lanparty boards have a feature in common "CPU Overheat Protection function monitors CPU temperature during system boot-up" Can be they use an separate chip for that, that is located below the chipset heatpipes.
