This AXDA3000KV4D was a trash pick from e-waste with an Abit KV7 and huge Zalman HSF. When I unscrewed the HSF, there was a huge amount of thermal paste, and I noticed a Resistor array was part broken.
Am I on the right track for a replacement that will do the job... If anybody has replaced one before? I have quite a bit of SMD experience, but haven't reworked an actual processor before.

102 is the value. They all are 102.

It's fairly easy, just use some hot air but add some solder to make it faster.
Air at an angle (blowing outwards) and it'll come off fast. To solder just use the iron, not air.
Pads are quite big.

It'll be hot afterward. Let it sit or use a fan to cool it down.

I've stumbled across this problem over the years, I remember one Barton core having a strange amount of L2 cache (64 or 128K) and thus being recognized as "Unknown CPU" due to a broken resistor network. The Mouser part seems to be just right, but I always recovered the part from one of the motherboards in the "dead" stash.

Recently I had one cpu @667 MHz instead of the rated 1800 IIRC.
The array was broken.
I recycled one from another dead cpu. In fact I have a lot of dead XPs. It was even too easy to damage or kill one.
