Hmmm.........curiouser and curiouser.

The top chip appears to be a multi-phase switch-mode voltage regulator made by an outfit called Voltera. I'm trying to get some data on it right now, but they are being snooty. I'd guess that it is the regulator for the vCore.

The other chip is a dual single-phase switch-mode plus single linear voltage regulator made by InterSil. Pins 1, 4, and 12 provide the regulator feedback and should be at whatever the output voltage is supposed to be. Since one of the recommended applications for this bad boy is as a voltage regulator for DDR memory, it is probably responsible for vDimm. Do you have a volt meter?
