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,
Interesting case, I have a gtx 980ti which suffered typical drmos failure. I replaced it together with 12V PEX switching transistors, all blown fuses etc. No shorts on vcore, vmem, pex or any other rails.
Yet the card does not give any sign of life when plugged into pcie x16 slot unless I plug it in via a mining riser?! I was troubleshooting it using riser as it is easier to measure etc. It worked so I assembled the card put in the computer and no post. When I move it to the riser it works again.
Checked all voltages on PCIE finger 12V, 3V3 while... -

Do you want to know the chip resistance value?
Is this resistance FBD_ZQ2?... -
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.
