Radeon HD3870 X2, Identify Component

[Byte_76]

I have a Radeon HD3870 X2 which has all voltages and cores get warm but the card is not detected by the PC.

There is this component on the PEX reset line but I don't know what it is and what the pinout is.

Can anyone help me to identify the component?

[ktmmotocross]

it should be and gate working as PEX RST buffer

Okay, yes but is there a reference to a part number that will have the identical functionality?

i want to look up the data sheet and order replacements but I need to be sure it’s the correct part.

The image is blurry, clean the IC with some IPA and see if you can read the marking

Byte_76 take a photo with the light at the right angle, the reflection will help reveal the letters and numbers

I have taken more pics with slightly different lighting angles on each.

Tested in multiple PC’s. The card is not detected by the PC. Both cores do get hot.

I’m still a novice at graphics card repair so I’m not sure what to check or where to check on the board for voltages or faults.

I’ve circled the location of the components that I am asking about in this thread.

Any ideas?

just use any and gate from literally any gpus. all use the same pinout

Thanks. Would this be a suitable replacement?
