Is my CPU multiplier safe?
Hello!

So my question is about the CPU multiplier clock whether it is safe or not.

first of all i'll give u my build:

Motherboard: Asus Gryphon Z87
Power Supply: Chieftec A-135, 400-650W (ordered Seasonic S12II-620 that should be here in few days)
CPU: Intel i7 4770k
CPU Cooler: Noctua NH-U9B
GPU: MSI Geforce GTX 660 Gaming Edition
Memory : Team Elite DDR3 2gb(x4) 1333mhz
SSD: Samsung 840 PRO 128gb (boot drive)
HDD: ATA ST31000528AS SCSI 1TB
Case: Fractal Design R4

I have never clocked CPU other than enabling turbo boost in BIOS that increased my multiplier from 35 to 39 (and maybe some Voltage?) which gave me 3,9ghz speed on CPU and it has worked without fail for almost 1 year.

Few days ago i decided to update my BIOS from first version to latest and since then my CPU multiplier increased from 39 to 43 so now my CPU is running at 4,3ghz and 1,225V.

So...i wonder if this is safe and stable or should i be better of setting the max multiplier to 40 instead of 43?
Running prime95 for 30 mins with the "blend" torture test i succeeded with temp 75c and went up to 95c once after 10 min for about 5 seconds and dropped back to ~75c.
Playing games like Battlefield 4, Shadow of Mordor and Batman Arkham Citites i never go over 50c

Should i just be happy i have a stable CPU at 4,3ghz or set multiplier to 40 to be safe?

core speed 4,3ghz
multiplier x8-43 (always running on x41-43)
bus speed 100,16mhz

Thank's in advance i hope i didn't make this "essay" to hard to understand.

so if i haven't had any issues with this clock there's no need to change it?
