Question Need help identifying Motherboard Chips

[buster108]

Hi,

Yesterday accidently hit my board with a screwdriver near the pcie slot. Took out from the looks of it, two traces. See here: https://ibb.co/hgqQwLx

I Painstakingly followed the traces. They end in those two little dots that ive highlighted in blue and red: https://ibb.co/XyWB3nm


Which seem to end in either of the two chips to the right and left of them?

I got the name and function of the smaller chip on the right: GL850G KSA0160 1471100

One return came up from a search, a pdf explaining all about this chip. Its the USB 2.0 controller. No loss at all for me that.

The other chip, the ITE one, is tricky.

ITE IT5701E - 128
2240 - BXA S1B9MAGB03

Googling it5701e gets some good results. However, as seen in the images its a mixed bag. Some say its RGB controller or the q flash bios function or both. Not sure what to make of that. If it is just RGB no loss for me. Q flash would be a shame. Would I lose my ability to flash my bios overall? Surely that functions remains in the m-bios chip?

Thanks !

so why do you wanna know the chips?
just bridge the lanes carefully with a wire soldering it to the broken lanes

or just try using the board, if you are sure there is no shortcut

Hey well since then I've tested every single header, slot or function down on the board there and it's been fine. also I am nowhere near skilled enough with soldering to even attempt this, could easily mess things up further. On inspection I reckon I might have just chipped the protective layer off and exposed the traces, rather than cut them. Given I've tried everything but q flash, I just put nail polish on the top to protect it. If I'm in the position where I need to use q flash then something else has already gone very wrong anyway haha.


For anyone who comes across this post in the future needing answers, gigabyte support said the ite it5701e chip is used for q flash here.

"They end in those two little dots that ive highlighted in blue and red." You can't assume those traces end where you think they do. The things you marked in red and blue are called "vias". They could be connected to traces internal to motherboard that go almost any where.

The only way to figure that out is with a schematic of the motherboard.

They are for sure conected to internal layers, that is what 'vias' do. They dont end there, they go somewhere else and without schematic is very very hard to see where they go, especially for multi-layered board how a motherboard is.

Hi yeah was informed of this in another post. Since the chip accident the pc has run fine. Stress tested the major components. All my fans and front io are working as normal.

So then i ordered loads of parts to tests the other headers. Pcie x1, the secondary m.2, both usb 2.0 headers, both types of RGB/LED headers, tested the reset switch. All fine. I think I either didnt actually cut the trace or it leads to most likely the q flash chip. However, as you both said those traces ending there doesnt mean it necessarily goes there. So if I have cut something, it seems its not something I will ever use in my use case. I am not going to test the q flash test however as that could end really badly. I will just to continue as if the board does not have that functionality. If im in a situation where I need q flash, then something else has already gone badly wrong.

Could even lead to the seriel ports that are recessed so not used by this revision of the board. Whatever actually has happened, I seem to have dodged a bullet and learnt a lesson in the meantime from it all.
