Hello, can anybody help me with information about some resistance on the board?

Hi guys, i was wondering, i've got 9Ohms on Vmem, one of the mosfet was shortet to ground, so i've desoldered hi and low mosfets nad still low res, then i removed all of the memory chips, and the resistance is still low, so did you had maybe a card with that low res on memories, and the card was working fine ?
Removed the U1866Q and still without result, i dont have thermal cam so can't see where is hot spot when incjeting voltage.
The resistance on core is ok 0.1Ohm ((Power 0.8V when on)
Resistance on 12V 4K ohms (Power present when on)
Resistance on 12V PEX 4K ohms... -
Hi, I'm Daniel, and I'm new to the world of repairing motherboards.
I would like to create a table, or more likely a guideline about the voltage rails and their possible resistance rail.
I know that the motherboard design has a very big depend on the rail's resistance, but I would like to know what is the smallest value for a rail that can be acceptable. For example, I heard that some new gaming motherboards can have 0,5 Ohm resistance on the GPU rail, but on an older type, it could be a sign of a shorted GPU rail.
So, I generated a table with AI so I can... -
Hi I need the reference of this mosfets I upload a photo.
Green marked?
Red marked?
Thx in advance... -
I have Asus FA506 ( board DA0BKXMB8D0 Rev: D). Can you please roughly indicate what the lowest resistance I should measure on a coil? I know that a low resistance is allowed on coils in CPU or graphic circuits but can you provide acceptable values of resistance?
Thank you. -
Hy guys , i have a DVR board DS-80104 REV 2.2 that was powered wrong, i have some smds on the board that are blown and i can't identify them , maybe if someone has this board somehow and we can identify the smds', i have searched online and i can't find a schematic.
The smds are SOT-23-6 , one of them i think it has the marking ADJF since i found another one on the board with this marking , but the other one it seems that it starts with AG or it looks like. I would really apreciate if someone could help me identify those IC's .
