Might not be the right place, but since it has some relation to the BIOS update to H87/B85 chipset that enables overclocking of K series Haswell;
i5-4440 in an Asus H87M-E motherboard with BIOS version 0604 out of the box (dated 30/8/2013). Detected as i5-4440 in BIOS, Windows 7 (My Computer -> Properties), CPU-Z, HWmonitor.
Then I flashed the BIOS to the latest one at https://www.asus.com/Motherboards/H87ME/#support to 0904 (dated 17/1/2014). The changes I observed;
Still detected as i5-4440 in BIOS, Windows 7. But in CPU-Z and HWmonitor it now shows i5-4670S.
Still clocked as 3.1ghz with 3.3ghz turbo like a 4440 and 84w TDP, as 4670s suppose to have 3.8ghz turbo and 65w TDP.
Anybody knows what happened here?
I suggest you to contact ASUS support service since this is mobo specific question.i5-4440 in an Asus H87M-E motherboard with BIOS version 0604 out of the box (dated 30/8/2013). Detected as i5-4440 in BIOS, Windows 7 (My Computer -> Properties), CPU-Z, HWmonitor.

It could be either BIOS or CPU-Z/HWMonitor issue.

what is the common stable voltage for 4770k at 4.5ghz 24/7?
does it need to run 4c/8t?
may i know best batch for this CPU? I need to know as im planning to get 4770k.
Voltage required is depends on chip and it's unique from chip to chip. does it need to run 4c/8t?
may i know best batch for this CPU? I need to know as im planning to get 4770k.
From what I observed a 4770K @ 4.5GHz around 1.15v is a good chip, bad chip like mine requires 1.25v+.
If you don't need 4C/8T then might consider to take the 4570K 4C/4T.
There is no best batch it's all depends on luck.
