Re: Palit 2060 ic identification
Thanks so much!
Are there any alternatives that can be used?
Aliexpress will take a while

Why does the gpu die have a thermal pad on it, should have thermal compound.Leave a comment:

Palit 2060 ic identification
Hey guys looking for a little help on an IC chip that gets extremely hot, i think its a buck converter but want to be sure to get the right part.
The identifiers on the chip are:
7222
0VWV
I have been unable to find pcb images of the model the 2060 (2060 Dual the Palit 1660 super has a similar 20 pin chip NCP81278 the board layout in that area is very similar)
Thanks for looking in on the thread!... -
Re: Asus 1660 super with blown mosfet, help needed to identify pads and a capacitor
I have a voltage here but it's only 0.9v this is close to the pcie slot and the 1.8v probe point, from ground the voltages are as in the photo, I think this is the 5v regulator as measuring from the 5v probe point I get voltages, however the 0.85 leg only shows 0.06v, get no readings from the 1.8v probe, any clues on the routing and likely refulators for 5v 1.8v and 3.3v, any help appreciated, the mosfet I replaced is getting 12v probing pmq1 and 2.
Any helps appreciated or any schematics...Leave a comment:

Re: Asus 1660 super with blown mosfet, help needed to identify pads and a capacitor
After further inspection 1.8v 5v and 3v, pex, gpu, mem... probe points have no voltage.
12v is present.Leave a comment:

A little update, mosfet replaced, on poking about with multimeter mem, pex and 1.8v appear to be connected to ground.Leave a comment:

Re: Asus 1660 super with blown mosfet, help needed to identify pads and a capacitor
Must be some way of recreating what was once there surely, just seems odd for there to be a grounding pad underneath the layer of where a positive rail goes across.Leave a comment:

Re: Asus 1660 super with blown mosfet, help needed to identify pads and a capacitor
Thanks for your reply, was thinking of using copper tape with a non conductive side and pcb mask between the coper tape and that area of exposed ground.Leave a comment:

Re: Asus 1660 super with blown mosfet, help needed to identify pads and a capacitor
Here are some of my findings, hope this may help someone in the future, the capacitor measures 10uF off board so I believe its a 16v 10uF multi layer capacitor that's missing.
I also found alternate points for the burnt pads on the flip side of the board by taking off the good fet to see how the traces are made up, the long pad pins 3 and 4 and the 10uF capacitor are all in the same circuit with continuity between the 2 pair of via points on the good fet but zero continuity on the bad one,...Leave a comment:

Thanks for your reply it's pad 10 on the datasheet, looks like it's completely gone on the board.Leave a comment:

Asus 1660 super with blown mosfet, help needed to identify pads and a capacitor
Hey guys yet another 1660 in for repair this ones got a bad FDPC5018SG which I have removed, the pad was fused to the fet so there is not much left of what would have been a pad, my question is what would that pad have connected to would it have been a grounding pad similar to the larger pad or should it have a trace going to a component, also there is a missing capacitor, wondering if anyone could give an approximate value for the cap near the other fet marked in red my esr meter gives 598uf on the board yet to desolder it off to check out of circuit.... -

Re: EVGA 1660 XC out of warranty, blown chip
Does anyone have a Evga 1660 XC (i think the TI may have similar chip, also some Palit cards have this chip too, its right next to a pair of 6 pin ic chips in parallel)that they could measure continuities and resistances for me off this chip from a grounding point to each pin.
The main ones I'm interested in are the ones between where mine has blown, I think they go to the capacitor adjacent but I'm unsure if the pair are bridged or have their own routing per pin, many thanks in advance.Leave a comment:

EVGA 1660 XC out of warranty, blown chip
Have an Evga 1660 XC that's got a bad chip blown (ebay seller says onky boots in safe mode), I've had some help pinpointing the chip as EMF20B02V Field effect transistor, its pretty fried:
Here's how it looks desoldered:
Looking for some advice on repair, the area where its blown makes it difficult to trace the copper conductive tracks, I'm unsure if it was one large rectangular pad or if the area is mirrored the same as its opposite side with 2 separate contacts, its hard to tell without anything to reference to.
Any help and advice is appreciated,... -

Re: Graphics card Schematics and Boardviews
Any boardviews out there for an EVGA 1660 XC I'm trying to identify the component in red to replace as the one on my board is that crispy you can't see any of the numbers on it.
Thanks in advance....Leave a comment:
