Ok, I made a wrong assuption and yes, there is a smd NTC under the CPU, in the space inside the socket, so ill work in that direction.
As far as I could check, the resistor and the connection to the I/O chip is ok, have to check a pair more of details and will post if there is any good news.
Thanks a lot
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

MSI MAG Z390 Tomahawk BIOS temp, allways at 0ºC and CPU goes protection 800Mhz
Hi to all, my motherboard (bought second hand as faulty, but now working after cleaning the ram slots) have a strange failure that shows 0 Celsius degrees in BIOS, because of that, the CPU goes to protection mode and gets stuck at 800Mhz.
Since its a 8-9 Intel generation, I know the CPU temp is the hottest temp of the cores (as i have read in intels documentation) so its not a diode or sensor on the board.
External temperature (motherboard temp) is working OK, 27ºC more or less
In windows, all the software I have tested shows correct the Core temps

DELL XPS 9560 Burned zone need photo please
Hi to all, I have a XPS 9560 with some faults, im working on it for fun, I have a "burned" zone I need to dremel but afterwards ill need a photo of the zone for rebuilding as far as I can, I have the schematics and the boardview but will like a photo, if some of you can get any so I see the traces will be cool.
It was some kind of lucky that the zone had not too much components, so I think I can deal with it.
Its under the zone where PC308 PC309 and PC337 is located, next to PU300
Thanks a lot for all and "pray" for me ...

Re: I need help with fixing my HDD(WD25000AAJS)
First, if you didnt yet, clean both pcb and then clean well the contacts on the J1 "connector" pads on both pcb, they look some dirty and maybe you think its not that serious, but i revived a pair of HDD cleaning those contacts, may worth a try. A pen eraser does it nicely, try to make them as shiny as possible.
Good luck

Re: GTX 1660 BIOS Beep Error
Does the own card has a buzzer? first time to hear about that. Or do you mean the beeps of the motherboard?

Re: RX470 8GB FE freezes
Well, after some test, I have tried diferent Bios, and modifiying them with polaris editor, but nothing turns it ok.
In polaris editor I tried to change the voltages of the ram when it goes faster, cause it goes to 1V when it crashes.
The fact is that all voltages (ram and core) goes up to 1V when it freezes, before that they stay at 0.9V
Have tried many times Tserver at diferent configurations (at the first post I said Matss, but was refering to Tserver) and all of them it says there is no error and card doesnt freezes...

Re: ASUS Sabertooth 990FX REV.2 bios chip problems, probably socket shorted?
Hi, from my experience a 3V on battery is low and I have motherboards that will reset to defaults when its 3V or under.
Did you try to change the battery to a newer than 3.1V one? maybe that one goes under 3V when powered off

Re: Repopulating SATA ports -- HP 800 G2 SFF.
Hi, try saving the bios from the SFF and install the TWR version, maybe it works, if not, turn back to SFF bios.
Soldering a sata port will not tell the board that there is a new sata port, so that should have been the last thing to do, first let the motherboard know it has 5 ports.
In worst case you can buy a PCIex to Sata card, I know that is not what you want, but its the worst scenario solution.

Re: GTX 1060 6GB - Not Recognized Properly
Hi, look at the front and at the back of the card, it uses to have 2 bios chip, dont really know why, but all the nvidia cards I have has 2

Re: GTX 1060 6GB - Not Recognized Properly
Did you try in windows? look what gpu-z tells about it bios rom, maybe it was modified. What make and model is it?

Re: Nintendo Switch drains battery in 2 days when off
Hi, thanks a lot, in these days ill look about it and ill try to replace the battery with my bench supply, so I can see the miliamps it takes when turned off now and after cleaning or removing that MAX, thanks a lot again, will post my findings

Re: RTX3070 Gaming pro power issue
Ah, ok, so the problem seems to be with the memory. Maybe any of them has a short of somekind and it makes the vram regulator to go to 0V and then disable other minor voltages.
Maybe you can inject 0.8V to 1V to rams and see if any of them heats up? (any mem or capacitor, resistor.. of that rail)
Do you have any schematics of any 3070?

Re: RTX3070 Gaming pro power issue
Ok, so look at the PEX circuit, its made assuming 1.8 is present, and if PEX is lost, Vcore is lost.
Find the PEX generation circuit and chip, after that, look if the enable for that circuit is lost after that 15 seconds, if enable goes 0V, try to find why, if it is there, it is faulty PEX generation circuit or chip.
This scheme is for Pascal GPUs, maybe it helps someway

Re: RTX3070 Gaming pro power issue
Hi, the sticker near the pci is kind of dirty, maybe someone tried to fix it before? What about 1.8v after that 15 seconds? PEX voltage comes from 1.8 as I know

Nintendo Switch drains battery in 2 days when off
Hi, I fixed a nintendo switch that was faulty replacing the M92T36 chip, since it had a short meassured in near capacitor.
After that the console works ok, but i find 2 problems, one I dont know it it is normal, the second problem I know is not normal.
BQ24193 charging chip heats a lot when charging, reaching near 70 degrees, with console open, with no disipation from the console chasis, so I dont know if it is normal. By the way, it charges ok, but would like to know if it should heat so much (meassured with a thermal camera and i can touch it because it burns)...
