Max TURBO Multiplier with 1/2/3/4 Cores is 32x/31x/30x/30x
GPU (HD4000) frequency: 650Mhz-1050MHz

Strange CPU. At stock slower than 3610QM. Bad Turboboost behavior

I approve what is written above. It is shown like 3720QM ES in CPU-z but it is way not 3720QM.
I wish Viktor wrote this a week earlier:(

This is just the same xm cpu but early stepping.
Stock clock is lower than the brother 3920 or 3940xm, but who cares about stock clock when using extreme cpu.

Multiplier overclock is unlocked, L3 cache is 8mb, TDP is 55w, which is exactly same is 3920 or 3940xm CPU.

Used it for 2months with 4.1 4.1 4.1 4.1 clock. No BSOD. Rock-stable.

Worth getting it if one can for it is much cheaper than oem xm cpus.
