Merom T7400 e1705 A01 vs A02 bench results.

Here is a quick run of tests on A01 vs A02 on my e1705 with a T7400 running. The upgrade worked fine with my yonah back in. Then I just swapped back to Merom and had no issues so it is supported and works.

Tempretures are in line with what I was seeing before.

Idle 28-30 cel.
100% load max'd at 70 cel.

Here are the benches.
