CINEBENCH R10
1 CPU=> 3955
x CPU=> 14398

PCMark Vantage => 11844

3DMark Vantage => 16362

Phenom II X4 965 default clock is 3.4Ghz, so the performance is quite high.
As 45nm manufacturing CPU, 1.4V is a little bit high.

AMD DRAM Performance
I use CORSAIR last dual channel product, DOMINATOR-GT CMG4GX3M2A2000C8
Clock is DDR3 2000, Latency are CL8 8-8-24, and voltage is 1.65V

CPU 3.4Ghz
DDR3 1607.4 CL6 6-6-18 1T
Sandra Memory Bandwidth - 9320MB/s
EVEREST Memory Read - 13289MB/s

CPU 3.825Ghz
DDR3 1632 CL6 6-6-18 1T
Sandra Memory Bandwidth - 9617MB/s
EVEREST Memory Read - 14274MB/s

AMD CPU has built in the Memory Control. During K8 stage, AMD had very high memory performance.
Since years, Intel also uses similar design and support Tri-channel. It makes AMD far away behind in DDR3 performance.
During my test, DDR3 can be stable at 2160 in Intel, but even it’s difficult to over DDR3 1700 in AMD platform.
In fact, AMD DDR3 is difficult to tune. Even the best capable AMD CPU, highest DRAM is only around DDR3 1800.
I think AMD needs to improve more for catch up the extreme segment. It’s nothing about memory capability now.

Phenom II X4 965 Temperature
Cooler is Tuniq Tower12 Extreme, the top level cooler in the market now.

CPU 3.825Ghz
Stanby - 40

Full speed - 59

45nm Phenom II is improved a lot which compare to 65nm Phenom.
Even I OC to over 3.8Ghz, the temp is still lower than 60.
Of course, Tuniq Tower12 Extreme cooler is indispensable contribution.
