50 ohms on 1V8 is not a good sign, should be ca 0.9kohms, GPU failure quite probable. You can try to use Mats/Mods to test the card, if no test possible, and the card is not recognized, then this...

Solder leakings must not mean the mosfets are bad, this can be remains from the production process. Check first if all voltages are present or not. Then you should desolder and check the mosfets,...

Re: is PCB bump did not make a serious problem? gtx680 Graphics card

Hi, recently I have made just for fun some tests on a similarly destroyed motherboard (not my achievement), if such bublles are possible to remove. And, in fact you can do it, heating the board to...

Re: MSI RX6900XT - i fcked up - shorted TOUT with BOOT on

The 5470qe is probably a custom chip, no datasheet/public offer available, only solution is buy another broken card and use it as donor. You can try to write to Alpha&Omega, but wouldn't expect a...

Re: ASUS STRIX Z490-F GAMING - No POST, stubborn board

Hi, you are right with SLP_S3#, I was somehow stuck in my thinking like this board :). It must be low in stand-by mode, and it should goes H on Power Button press. I have to rethink now, thanks for...

Re: ASUS STRIX Z490-F GAMING - No POST, stubborn board

That was also my initial idea, but then I traced back the EN signal for the mosfet keys which give the power to the CPU VRM chip (and 5V_DUAL), and these signal is forced down to zero by something, I...

ASUS STRIX Z490-F GAMING - No POST, stubborn board

Hi,

I have this very stubborn ASUS mobo on the bench, and I already face the wall with it. It just refuses to POST, although everything seems to be OK.

Re: GTX 980 Artifacting even after ram chip swap and core reflow

There are principally 3 (4) options: bad memory, bad connection between GPU and memory, bad GPU, OK also a fourth one, missing/decalibrated caps/resistors around the mem chip. If you rule out memory,...

Re: CMOS battery discharges constantly and extremely quickly

You need to check the resistance on the + pole of the battery connector, should be in Mohms range, if you have it lower, then somethings draws too much power, most probably the chipset (where the...

Re: Renesas RAA 229004

Hi, there is no datasheet even at the Renesas site, so it might be not released still or it's a custom chip. The only information avaliable is attached, but not much of use as pin numbers missing....

Re: MSI RTX2070 code 43

Which programmer do you use ? If you use CH341 it has a design flaw and can destroy the 1.8V bios chips. It is good for motherboard bios chips (3,3V), but not for graphic card bios chips. It's...

Re: MSI RTX2070 code 43

Code 43 will most probably be a broken memory chip or cold solder of memory chip or the GPU. You can try to bend the powered card slightly to check if the picture comes, if yes then you have to...
