Yes, i'm sure - when machine starts it shows:
Slot 0 HP Smart Array 6i Controller (192 MB, v2.58) 1 Logical Drive
and when we put it out it shows:
Slot 0 HP Smart Array 6i Controller (64 MB, v2.58) 1 Logical Drive

We did tests with and without battery:

dl380 (CPU: 3.6GHz) without cache: 2h 34m = 154m
with cache: 2h 25m

without cache: 1m 24s
with cache: 2m 49s

wo. cache: 4m 58s
w. cache: 4m 57s

wo. cache: 4m 40s
w. cache: 4m 38s
